GETTING STARTED
INTRODUCTION
Welcome to FIRAXIS Games’™ second offering, Sid Meier’s Alpha Centauri™.
As with all games from FIRAXIS, fun and imagination rule, and we have tried
to make a very complex topic accessible and interesting.
It is an ambitious game, addressing some very fundamental issues facing
mankind as we approach the new millennium. What sort of technologies can
we expect to deal with within the next couple of centuries? How will we use
these technologies — for good or for evil? In fact, what ideologies will be paramount in the next millennium, and do these ideologies imply new and differing definitions for “good” and “evil”? What is the ultimate goal for humanity?

2

THE STORY
Soon after the new millenium begins, humankind’s oldest enemies — war,
famine and disease — are winning the battle on planet Earth. The United
Nations decides to attempt the mission that has been the dream of countless
science fiction writers and fans for generations: the colonization of a New
World, before it is too late. The establishment of a new outpost for mankind
as an alternative to the decaying situation on our mother planet seems to be
the last and best hope for the continued existence of mankind.
Code named “Unity,” the plan is simple. Send enough men, women and supplies to the earthlike planet, Chiron, orbiting the primary star in the Alpha
Centauri system. Give them the seeds for planting a new society — technology, knowledge, and experts of every kind. Insure that the mission, U.N. sponsored, stays on track by carefully monitoring its progress from Earth. Then,
when the time is right, and if the need still exists, begin shuttling others to
the New World at Alpha Centauri.
But space travel is a difficult undertaking, even now. It is hard to reach our
own moon. Even if we had the capacity to make it to a distant planet, will we

G E T T I N G

S T A R T E D

C H A P T E R

be able to bring the travelers back? Once firmly established on a distant world,
will we be able to cooperate with one another there long enough to establish
a new society that can attain the same levels and quality of life that we have
achieved here after almost 5000 years of civilization? But the deteriorating
conditions on Earth leave us little choice.
From the beginning, there are problems aboard the U.N. Starship Unity. An
unexpected reactor malfunction damages the ship, waking the travelers early
from cryo-sleep. It soon is evident that the accident has damaged the communications equipment and contact with Earth is lost, and cannot be reestablished. The leadership of the mission is faced with the prospect of going
it alone and soon begin to argue obstinately about the best way to proceed.
The game begins when the Unity Mission reaches Chiron. But, by this time, the
mission has fallen into chaos. The most powerful leaders on board have built
ideological factions and surrounded themselves with dedicated followers. It is
clear that each faction has established its own agenda for the future of
mankind and is desperately serious about carrying it through.

GOOD LUCK
We hope you will find a multitude of ways to solve the problems the Unity
travelers face. There are nearly unlimited options and you can experiment
relentlessly as you explore, discover, build and conquer. Please feel free to contact us to pass on criticism or praise, or just your point of view, at
WWW.FIRAXIS.COM. Have fun and Good Luck.

USING THE MANUAL
If this is the very first time you’ve ever played Sid Meier’s Alpha Centauri or
any game like it, we recommend you do not sit down and read this book
cover-to-cover before you start playing!
Instead, we strongly suggest you put down this book, start up the game, and
play through the tutorial scenario provided. Also, check out the five “tours”
provided in the game’s Help menu. These two resources are the easiest (and
most fun) way to learn the basics of the game.

G E T T I N G

S T A R T E D

Tours. To get to the tours, start the game and select any options which look
interesting (you’ll find out exactly what they do a little later) or just hit QUICK
START. When the game loads for the first time, you will be automatically
walked through several tours that show you the fundamentals of the game.
To get back to the tours after the first game, L (left-click) on the MENU tab
on the left side of the screen, then L on HELP. The tours are at the bottom
of the Help menu.

4

Tutorial Scenarios. To access the tutorial scenarios, start the game and select
SCENARIO from the Main menu. When the Scenario menu appears, select
PLAY SCENARIO. Open the folder 1EXPLORE and select the “Explore.sc” file.
Upon successful completion of the “Explore” scenario, move on to the
2BUILD folder, and then to the 3CONQUER folder. When played in succession, these tutorials can help teach the Sid Meier’s Alpha Centauri basics in
a fun and intuitive way. To access a list of scenario objectives and how to
achieve them, L on the MENU tab on the left side of the screen, then L on
the HQ menu, and select REVIEW SCENARIO OBJECTIVES.
Once you know the basics, this manual is provided to help you discover the many
subtleties and details of Sid Meier’s Alpha Centauri. We hope you’ll be returning to these pages often while playing, to discover the exact purpose behind a
game option, or the meaning of a term. Who knows? Maybe after you’ve been
playing Sid Meier’s Alpha Centauri for awhile, you’ll come back and read this
book cover-to-cover, just to make sure you’re not missing anything.
In addition to this manual, you will find the following materials, also included with your game, extremely useful:
• Install Guide. Installation, trouble shooting and customer support.
• Tech Tree Chart. The technologies that you discover as you progress, and
their interrelationships. This chart also contains information about the terrain, vehicles, and world of Sid Meier’s Alpha Centauri.

GAME SETUP
Sid Meier’s Alpha Centauri allows a wide range of player customization
options both before and during play.

MAIN (STARTING) MENU
This is the first thing you see
upon starting Sid Meier’s
Alpha Centauri.

6

You can quit the game from
the Main menu with q. If
you’re not on the Main
menu, q takes you back to
your previous screen. On all
menu screens, q takes you
back one level.
START GAME
Starts a new game. This selection opens the Map Selection menu (see Map
Selection menu, facing page).
QUICK START
This option drops you directly into a new game configured exactly like the last
game you played (including faction choice). If you use Quick Start before playing any other games, it drops you into a world of average size, with all defaults
on, playing the Gaian faction on the easiest difficulty level.
SCENARIO
Scenarios are specific challenges designed to test your playing skill to the maximum. The exceptions are the Tutorial Scenarios, specially designed to teach
new players the basics.

G E T T I N G

S T A R T E D

C H A P T E R

LOAD GAME
Allows you to load a previously saved game. You can load both automatic
saves (see Automatic Saves, p. 30) and named saves (see Save Game, p. 29).
This option opens your Saves directory.
MULTIPLAYER
Use this to set up a multiplayer game. See Multiplayer, in the Install Guide,
for detailed instructions.
VIEW CREDITS
Reveals the game’s creators.
EXIT GAME
This option quits the game and returns you to Windows®.

7

MAP SELECTION MENU
In this menu you decide what kind
of new game you wish to start.
MAKE RANDOM MAP
Allows you to start a new game,
making only a few basic choices—
Size of Planet, Difficulty Level, Game
Rules and Faction. (See Customized
Planets, next page, for details of
these options.)
CUSTOMIZE RANDOM MAP
Allows you to customize a number of parameters of your new world before
you start play. See Customized Planets, next page, for details.

THE MAP OF PLANET
This map is the “official” map of Planet. It’s always the same.
HUGE MAP OF PLANET
This is a large version of the map of Planet.
LOAD MAP FILE
This allows you to load a custom map that you’ve saved out as a map file.

CUSTOMIZED PLANETS
When you elect to play on a random or customized random map game, you’re given
a series of choices that allow you to shape the environment of your new world.

8

A fully customized planet allows you to control exactly what kind of game
experience you want. If your primary interest is combat and tactics, choose a
small planet with plentiful native life, giving you lots of opportunity to fight
off native threats and other factions. If you’re more interested in peaceful,
long-term development, choose a huge planet and rare native life. If you want
a difficult terraforming challenge, choose a mountainous, dry world, but if you
want a more inviting environment for your people, choose rolling terrain and
lots of rainfall. If you like building and managing a navy, go for extensive
ocean coverage, or if you prefer to work on land, choose smaller oceans.
At any time in the customization process you can return to the Select Size of
Planet menu by hitting q.

G E T T I N G

S T A R T E D

C H A P T E R

1

SIZE
There are five options: Tiny, Small, Standard,
Large and Huge. The bigger the world, the
longer you’ll probably play before encountering any of the other factions.
From this screen, you can also load any custom
map files you may have saved. The Load Map
File option opens your map file directory.

OCEAN COVERAGE
Allows you to select how much of the world is under water. The three options
are 30-50%, 50-70%, and 70-90%. The more ocean, the greater the necessity for a navy and the fewer opportunities to expand your faction on land.

9

EROSIVE FORCES
Allows you to choose between Strong (rolling and flat terrain), Average (hilly
terrain), and Weak (rough, mountainous terrain). In general, flat terrain is easier to settle and terraform. Rougher surfaces are harder to terraform, but offer
an abundance of mineral resources.
NATIVE LIFE FORMS
Allows you to select the frequency of Planet’s native life-forms, notably mind
worms (see Fauna, p. 40) and xenofungus (see Flora, p. 39). Choices are Rare,
Average and Abundant. The fewer native life forms, the easier the going, particularly early in the game.
CLOUD COVER
The choices are Sparse (light rainfall), Average, and Dense (heavy rainfall). The
more rainfall, the more nutrients available to feed and expand your bases.

G E T T I N G

S T A R T E D

C H A P T E R

1

DIFFICULTY
There are six levels of difficulty. The higher the
difficulty, the smarter and more aggressive your
opponents, and the tougher it is to establish
and expand your faction. Difficulty levels, from
easiest to hardest, are: Citizen (novice),
Specialist, Talent, Librarian, Thinker, and
Transcend (expert).
GAME RULES
These advanced gameplay options are
described in detail under Game Rules, p. 197.
FACTION

10

There are seven factions of refugees from the disastrous destruction of the
U.N. Starship Unity. This is where you select the one that you wish to lead.
• CUSTOM NAME allows you to change the name of the faction (if, for example,
your faction simply must be the Cheeseheads). This option also allows you
to customize the terms used to address and describe your faction in diplomatic interactions.
• HELP button displays a summary of the faction’s character and its special
abilities (and handicaps).
• LOAD lets you load a previously created faction configuration.
• OK accepts your choice and starts the game.
• CANCEL returns to the Main menu.
After you select a faction, you get a window that allows you to change the
name and gender of your faction leader (for example, Norma of the
Cheeseheads), if you wish, after which the game begins.
See Factions, facing page, for information about the seven factions themselves.

FACTIONS

The human factions of Planet are not divided by race, language or place of
ancestral origin. Instead, each faction is guided by the vision of its leader.
These visions, in turn, give each faction a unique set of advantages and disadvantages. By comparing the strengths of your faction to the parameters of
a customized planet, you can either give yourself an edge against the other
factions, or set yourself a unique challenge to overcome.
You’re likely to find the game more enjoyable if you pick a faction you can
empathize with (even if you don’t necessarily agree with everything they profess).
GAIA’S STEPDAUGHTERS (LED BY LADY DEIRDRE SKYE)
The Gaians are determined not to repeat the environmental mistakes of old Earth.
They seek to live at peace with Planet. They start out with the Centauri Ecology
technology and advanced abilities to interact with the native life, including the
ability to move freely through xenofungus squares and gather extra nutrients
from fungus. Their empathy with Planet gives them the ability to place ravaging
wild mind worms directly under their control. Their experience with recycling systems makes their bases more efficient, but their pacifist leanings undermine the

G E T T I N G

S T A R T E D

C H A P T E R

abilities of their military units, and they resent police control in times of crisis.
Because of negative environmental consequences, the Gaians can not make the
“Free Market Economics” social choice (see Society Window, p. 136).
HUMAN HIVE (LED BY CHAIRMAN SHENG-JI YANG)
This faction is ruled under harsh collectivist/authoritarian principles. The good
of the individual is totally subordinate to the state. They are isolationist, and
militaristic. The Hive begins with the Doctrine: Loyalty technology. Their bases
are built underground, giving them the equivalent of a pre-installed Perimeter
Defense facility. Their population growth and industrial development are above
average, but their economy tends to lag behind others. The Hive can not make
the “Democratic” social choice (see Society Window, p. 136).
UNIVERSITY OF PLANET (LED BY ACADEMICIAN PROKHOR ZAKHAROV)

12

The University is completely dedicated to research and the free exchange of
information. They are rumored to sometimes put the pursuit of knowledge
ahead of ethics. They start the game with the Information Networks technology and one additional bonus technology. Each University base receives a free
Network Node when founded. The University’s research progresses quickly, but
their open-access philosophy makes them susceptible to attacks by covert
“Probe Teams,” while their callous elitism can easily lead to unrest among the
workers. The University can not make the “Fundamentalist” social choice (see
Society Window, p. 136).
MORGAN INDUSTRIES (LED BY CEO NWABUDIKE MORGAN)
The Morganites are organized along corporate lines, and dedicated to laissezfaire capitalist economic principles. They start the game with 100 energy credits and the Industrial Base technology, and receive a bonus to all income from
commerce between factions. Morganites have expensive tastes, making it difficult for them to support units in the field, and requiring them to build Hab
Complex facilities before the population of any of their bases can exceed four
citizens. The Morganites can not make the “Planned Economics” social choice
(see Society Window, p. 136).

G E T T I N G

S T A R T E D

C H A P T E R

SPARTAN FEDERATION (LED BY COLONEL CORAZON SANTIAGO)
The Spartans are paramilitary survivalists. They believe in both a right and a
duty to keep and bear arms. The Spartans start the game with the Doctrine:
Mobility technology and a fast scout rover vehicle, and they do not have to pay
extra to develop prototypes of new units. Morale of their units is exceptionally high, and their citizens accept strict police control as a necessity, but their
extravagant military needs weigh down industrial operations. The Spartans can
not make the “Wealth” social choice (See Society Window, p. 136).
THE LORD’S BELIEVERS (LED BY SISTER MIRIAM GODWINSON)
The Believers seek a life of prayer and religious worship. Because of the
strength of their convictions, they get a bonus when attacking their enemies.
They start the game with the Social Psych technology. The Believers are resistant to probe brainwashing, but their suspicion of secular science retards their
research efforts, and their belief that Planet is their promised land sometimes
interferes with their ecological sensitivity. The Believers can not make the
“Knowledge” social choice (see Society Window, p. 136).
THE PEACEKEEPING FORCES (LED BY COMMISSIONER PRAVIN LAL)
The Peacekeepers exist to support the humanitarian principles of the United
Nations of Earth, the organization that originally commissioned the Unity
expedition to Alpha Centauri. They start the game with the Biogenetics technology. The idealism of this faction attracts an intellectual elite, but their society possesses a tendency towards bureaucratic inefficiency. Their bases can
exceed normal population limits by 2. Due to his experience with parliamentary
maneuvering, Lal’s vote counts double when the Planetary Council is convened
for election of a Planetary Governor or Supreme Leader. The Peacekeepers can
not make the “Police State” social choice (see Society Window, p. 136).

CHAPTER 2

WELCOME TO ALPHA CENTAURI

C H A P T E R

WELCOME TO ALPHA CENTAURI
Your new home in the Alpha Centauri system is officially called Chiron, but most
of the new inhabitants refer to it as Planet. In cosmic terms, Earth and Planet are
two worlds similar enough to be considered practically identical. But for human
beings, the product of millions of years of earth-specific evolution, Planet is a
strange, alien and frightening place. Your first task, upon arrival on this new
world, is figuring out the ground rules how the whole system of Planet works
together, and how your faction can make itself profitably a part of that system.

GETTING STARTED

16

A whole new world is a big place, and Sid Meier’s Alpha Centauri is a big
game. The first settlers on Planet are awed by the infinite possibilities that
stretch before them, and the first time you open the game, you might find
yourself a bit over-awed by all the choices you have (particularly if you’ve never
played any similar simulations before). This section is a quick guide to what you
can expect when you first start to play, and some of the basic and necessary
actions you need to take to get yourself established. All the concepts and
actions mentioned below are covered in much greater detail later in this book.

FOLLOWING PLANETFALL
When your faction first makes planetfall, you always have at least one mobile
unit ready for action. Send this unit out to explore the immediate vicinity of
your base (you can move your unit with the eight arrow keys on the numeric
keypad: just press the key corresponding to the direction you want to go). Try
to explore at least five or six squares out from the base in all directions, then
pick a direction and head out, or find a coastline and follow it. You’re looking for inviting places to establish new bases (remember, green is good — look
for green squares near rivers or coastlines), and for the supply pods scattered
by the Unity just before its destruction (but be careful—the Unity pods can
contain valuable gifts, but they can also unleash danger). Watch out for mind
worm boils—the dangerous native life-forms of Planet. Be prepared to fight or

run when you see mind worms (you can attack by attempting to move into
their square). Ultimately, you’ll want to make contact with the units or bases
of the other human factions.

RESEARCHING TECHNOLOGY
New technologies drive your survival and expansion on Planet, giving you
access to new weapons, base facilities, and Secret Projects. As soon as your
first base is established, your faction immediately begins scientific research.
You don’t have to do anything to start researching, it just happens. Every few
turns your scientists announce a new breakthrough, and ask you to set priorities to guide your next research effort. For more information on how to maximize your technological advances, see Technology, p. 119.

EXPANDING YOUR EMPIRE
Each of your bases is constantly building a new unit or base facility. You can
decide where a base should direct its industrial efforts. To do so, L on a base
to open the Base Control Screen. In the lower left corner of that screen is a
window showing that base’s current build orders. L on the Change button to
get the Production Readout, which shows everything your base can build (at
the start of the game, this might be just two or three objects). At the start of
the game you’ll want to concentrate on units. First, build a military unit to
guard the base. When it’s completed, use H to order that unit to remain in
the base, on guard. If you wish, you may order the base governor to take over
production if you L one of the “Governor” buttons at the top of the Base
Control screen (see Governor, p. 69).

17

As soon as the “former” (terraforming) unit becomes available (with the discovery of Centauri Ecology), build one and send it out to terraform the landscape.
Move the former out of your base and have it build farms (F), roads (R), and
solar collectors (S). If the terrain is harsh (a brown square with no green), plant
forests (sF). If the terrain is rough (lots of grey blobs in the square) drill
mines (M). You can also automate a former by pressing sA; it immediately begins building terrain enhancements as the former commander sees fit.

WELCOME TO ALPHA CENTAURI

C H A P T E R

You’ll also want to build some extra colony pods to establish new bases. When
a pod is ready, send it out to an inviting green square at least three or four
squares away from any other base (and on a river or a coast if possible). B
builds a new base on that square.
As your faction discovers new technology, you gain an ever wider variety of
build options to choose from. Once you have a defensive unit and a former,
and have sent out a colony pod from a base, you’ll probably want to start
improving the base itself by building facilities. Particularly useful facilities for
new bases in the early part of the game include the Network Node, Perimeter
Defense, Children’s Creche, Recycling Tanks and Recreation Commons.
Eventually, when you feel one of your bases is well established, you may want
to commit it to building a Secret Project. These massive works take a long time
to build but yield lasting benefits to your entire faction.

DIPLOMACY

18

Inevitably, you come into contact with one of the other factions from the
Unity. When this happens, you’ll usually get a message that the leader of the
faction wishes to speak to you, via your commlinks. It’s usually a good idea to
talk to another leader when given the opportunity. Leaders may offer to trade
technologies (often a good idea), or offer you a treaty, or even an alliance (a
very good idea, unless you’re itching for a fight). On the other hand, they might
threaten you or even try to extort energy (the currency of Planet) or technology from you. Giving in to such demands can be humbling, but is sometimes
better than the alternative (a fight you may not be ready for). Sometimes they
want to borrow energy credits (a good deal in the long run, unless you’re going
to need the energy you’re loaning away in the immediate future).

FACTIONAL STRIFE
Unfortunately, diplomacy can’t solve all problems. Sooner or later, you’ll have
to prepare your faction for armed conflict. Even if your intentions are peaceful, you’ll need a standing army, to respond quickly in case of unprovoked

WELCOME TO ALPHA CENTAURI

C H A P T E R

aggression. (Keep such defensive forces small—no more than two units per
base in the years immediately after Planetfall. Otherwise they’ll become expensive to maintain, and rapidly become obsolete.)
If you prefer the conqueror’s role, you can put your whole faction on a military
footing, building multiple units per base for a massive invasion force. Obviously,
you probably shouldn’t invest too much time and resources into an operation
until you’ve encountered the enemy and know where they’re located.

THE TURN
Sid Meier’s Alpha Centauri is a turn-based game. Each turn corresponds to
one Chiron year. Mission Year 2100, Planetfall, is the first Chiron year.
Each turn follows the same pattern.
1. Planet & Enemy Faction move. All native and enemy units make their
moves (including attacks). You see any such movements that fall within the
limits of your sensors. The leaders of the other factions may contact you.

19

2. Faction Update. You are advised of any completed enhancements, research
or units. (You can customize your preferences for updates; see Warning
Preferences, p.199.) You may set a new goal for each base when a project
is completed, or you may use the defaults. As time progresses, you are
offered opportunities to upgrade units, and may receive updates of your
progress at unraveling the secrets of this new world.
3. Player Move. You (and all other player-controlled factions, in multiplayer games)
may move units at this time. You are taken, in turn, to each unit that is:
• not “holding” in a defensive position, or “asleep” within a transport unit.
• not already engaged in a multi-turn action.
During this time, you may also freely change your preferences, or change
orders to bases or any units (whether or not they’re already engaged in orders),
contact other faction leaders, inspect visible portions of the map, and review
all available data.

GETTING AROUND
The first things you have to learn, in order to establish your faction, are how
to interpret the map and how to move around.
The main map, which occupies the top two-thirds of the screen, is your playing surface. At Planetfall (when your faction first arrives on Planet, and when
the game begins), the vast bulk of the map is either indistinct or totally black
(depending on how you set the Unity Survey option; see Game Rules, p. 197).
You have to move units around and explore to find out exactly what your surroundings are.
The simplest way to move a unit is with the numeric
keypad.

20

The direction in which the keypad arrow points corresponds directly to the direction the unit moves, so that
8 on the numeric keypad moves you one square to
the north, while 3 moves you one square to the
southeast.
It is also possible to set units to undertake longer,
multi-turn journeys without further orders, or
even to have them decide for themselves what
actions to take. These options are described
under the Action Menu (p. 92).

Continual movement c+arrow key
If you want a unit to move continually in a single direction, use this command.
The unit continues in the specified direction until it can no longer proceed,
due to coastlines or enemy units. The unit’s commander may route around
small obstacles like fungus and small bodies of water.

WELCOME TO ALPHA CENTAURI

C H A P T E R

2

MOUSE MOVEMENT
If you’re sending a unit on a long journey, and you don’t want to hit an arrow
key for every square of the distance, you can set a destination using the
mouse: Just L (left-click) on the unit, drag to its destination, then release.
The unit figures the most direct path to your destination, automatically routing around obstacles like small bodies of water and fungal areas.
Waypoints. There may be times when you don’t want a unit to take the most
direct route to its final destination (for example, if a route would take you
through hostile territory). In those cases you can use waypoints. To set a waypoint, L-and-drag to the first waypoint square, z while holding the
click, then drag to the next waypoint or to your final destination. A waypoint
is set on that square—the unit goes to the waypoint, then on to the next waypoint (if there is another one) or its final destination. A unit will normally follow the path shown on the screen when its orders are given, but it may deviate somewhat based upon the tactical situation at the time it makes the actual move. It always traverses the waypoints in the order given. You can insert
up to three waypoints on a route, including the destination.

21

EXAMINING THE MAP
The main map is scrollable. L (left-click) on any square to center the map on that
square. You can also scroll the map in the indicated direction by moving your
mouse cursor to the edge of the screen (unless you choose to disable this option).
• If you have a unit in that square, L also moves your cursor to that square
and activates the unit (see Active Units, p. 22). If you have multiple units
in a square, you choose which unit to activate.
• If you have a base in the square, L opens the Base Control Screen (see
pg. 66).
: (right-click) on a square to open a window containing many of the most
commonly used commands. These commands are fully described under Action
Menu, p. 92.

FOG OF WAR
On any given turn playing with the default game options, there are three types
of terrain visible on the map.
Black squares are squares you have not mapped yet. (If you have the Unity
Survey option turned on, these are not black, but you won’t be able to see any
details of the square’s terrain, other than whether it’s land or sea).
Dim squares are those you have already mapped, but which are not currently
observed by any of your sensors (either from units or bases).
Bright squares are those you’ve mapped, and which are currently monitored
by your sensors. Most units can observe only adjacent squares. All bases and
your units with Deep Radar (a unit special ability) can observe out to two
squares away.

22

ACTIVE UNITS
During a turn, each of your units not currently under orders will become active
and remain so until you either give it an order or activate a different unit.
Active units are shown by a marker or by flashing, depending on the game
options you have selected. A unit that has been skipped during your turn
because you chose to activate a different unit will re-activate before the end
of your turn as a reminder that it still needs instructions. If you are viewing
the map, press V to auto-select the next active unit.

COMMLINK
Although it may take awhile to find them, eventually you’ll need to communicate with other faction leaders. The commlink system is your means of communication and your tool for trade and diplomacy.
The Commlink button is located on the right edge of your screen.

23
L on this tab or press F12 to open the Commlink menu which displays the
names of each of the opposing faction leaders along with your current diplomatic status with that faction (Vendetta, Truce, Treaty, Pact; see Diplomatic
Relations, p. 129). L on a name to contact that leader (see Diplomatic
Contact, p. 127).
A final option, COUNCIL, cannot be used until you have the commlink frequencies for all other leaders. It allows you to convene the Planetary Council. (See
Planetary Council, p. 132.)

TURN COMPLETE
This button, just below the Commlink tab, allows you to disregard any remaining actions and end the turn (if you have actions left in the turn, you are
prompted to confirm your choice). This button flashes when all your units
have received orders for the current turn.

If you L on the M button (for “messages”), the Data MFD displays the most
recent messages generated by the game, with the oldest at the top.
If you L on the I button (for “information”), the Data MFD displays a continuously cycling series of screens displaying important information about
your faction and its status among the other factions.

MAPPING PLANET
When you first arrive on Planet, you’ll have no idea where you are, where the
other factions are, or indeed what might lie over the horizon. You’ll have to
begin the fascinating process of exploring Planet, and as you progress the
world map is unveiled.
The map of Planet is a spherical surface projected onto a rectangular image.
This means, in realistic terms, that the squares at the top and bottom of the
map (near the poles) represent much smaller areas than the squares in the middle (near the equator). In game terms, however, there’s no difference—a square
is a square. Understanding the projection, however, does make it easier to

WELCOME TO ALPHA CENTAURI

C H A P T E R

understand that the long stretches of rough land at the top and bottom of the
screen represent the edge of Planet’s uninhabitable polar regions.
MAP COORDINATES
Map coordinates are
numbered starting from
(0, 0), with the vertical
axis first. The vertical
axis is numbered from
the top of the map to
the bottom, and the
horizontal is numbered
from left to right, starting at the point where
the World View (see
World View, p. 24)
wraps. Thus (14, 22) would be nearer the upper left corner of the World View,
while (101, 77) would be much lower and farther to the right.

27

ARCHIPELAGOES
Some land squares are connected by a thin line between their diagonal corners, with water squares on either side of this line. These squares are connected by an archipelago of small islands, and these intersections can be
crossed both by sea units (from one water square to the other), and by land
units (along the archipelago).

Automatic saves are stored in the AUTO subdirectory of your SAVES directory.
The “Iron Man” option (see Game Rules, p. 197) turns off automatic saves,
except when quitting a game, for those who think autosaves make it too easy
to go back and undo embarrassing mistakes. If you manually save an Iron Man
game, you exit the game.

CHAPTER 3

PLANET

C H A P T E R

3

PLANET
Before you can turn your attention to the old terrestrial games of politics and
warfare, you must first focus on the serious business of surviving and thriving
on a strange world. Unlike the human factions, Planet cannot be conquered,
dominated or negotiated with, but it can be worked with to ensure the survival and prosperity of your people.

RESOURCES
Resources are the essential elements which you extract from your surroundings
to support and expand your faction. There are three types of resource—nutrients, which support your population and allow your bases to grow in size;
minerals, which allow you to build units and facilities; and energy, the currency of Planet.

36

To obtain the resources from any given square, it must be inside your territory (see Working the Land, p. 60), inside the production radius of a base (within a two-square radius, excluding diagonals), and that base must assign a unit
of its population to work that square (see Working the Land, p. 60).
Unworked squares yield no resources, regardless of their fertility.
Your ability to exploit territory is limited by your technology. When you first
arrive on Planet, you are generally unable to recover more than two of any one
resource per turn (see Resource Production Tables, p. 52). As you acquire new
technologies, your production capacity expands until you are fully able to
exploit the resource potential of every square in a base’s production radius.

NUTRIENTS (RAINFALL)
For your faction to increase, you must be able to extract healthy nutrients
from the alien ecosystem of Planet. The more nutrients a base produces, the
faster and larger it can grow. Rainfall directly determines the amount of nutrients a square can produce.

PLANET

C H A P T E R

3

There are three levels of rainfall on Planet—arid, moist and rainy. Rainy
squares show as green on the map, and are usually the best places to establish new bases. Arid squares show up as brown, and moist squares combine
green and brown. When scouting for new settlements, always remember,
“Green is good.”
Without any modifiers (such as special resources, enhancements, xenofungus,
monoliths and others, all detailed below), an arid square produces no nutrients, a moist square produces 1 nutrient per turn, and a rainy square produces
2 nutrients. Rocky squares (see Minerals, p. 37) do not produce nutrients
regardless of rainfall.
Moist and rainy squares are excellent places to build farms to enhance nutrient production. The amount of nutrients any given square can produce is limited until the discovery of Gene Splicing.

MINERALS (ROCKINESS)
Mineral production controls the rate at which your bases improve, as well as
your ability to produce military, transport and terraforming units. Existing
units may also require a certain amount of mineral raw materials for support.
The rockier a square, the more minerals it produces. There are three levels of
rockiness—flat, rolling and rocky. Without any modifiers (such as special
resources, enhancements, xenofungus, monoliths and others, all detailed
below), a flat square produces no minerals, while a rolling or rocky square produces 1 mineral per turn.
Bases cannot be established in rocky squares, nor can farms be started there.
They are, however, excellent places for mines. For more details, see Terraform
Menu, p. 46.
The amount of minerals any given square can produce is limited until the discovery of Ecological Engineering.

PLANET

37

C H A P T E R

ENERGY (ELEVATION)
A solar collector must be built in a square to harvest its energy from elevation.
Energy allows you to sustain your bases in working order. Even more importantly, though, it is the effective currency of the human factions of Planet.
The energy you collect is allocated to three different areas: Economy, Labs and
Psych. Energy allocated to Economy is used to maintain base facilities; any
excess is placed in the energy reserve. Your faction’s economic power is measured by its energy reserves. These reserves are saved in the form of “energy
credits,” and are used for maintaining base facilities, commerce and energy
payments between factions. Energy from the energy reserves may also be
invested in mineral production to hurry projects to completion (see Build
Orders, p. 67). Energy allocated to Labs speeds research into new technologies
(see Energy Allocation, p. 117). Energy allocated to Psych helps maintain
order in your bases (see Energy Allocation, p. 117).

38

Squares with solar collectors produce 1 energy per level of elevation. There are
four levels of elevation above sea level on the Planet—0 to 1,000 meters above
sea level, 1,000 to 2,000 meters, 2,000 to 3,000 meters, and above 3,000
meters. For example, a solar collector built in a square at 1025 m would produce
2 energy each turn. You can find the elevation of a square by checking it in the
Status View (p. 25). You can also see elevations and depressions on the map.
The amount of energy any given square can produce is limited until the discovery of Environmental Economics.

CLIMATE AND ELEVATION
The rainfall of a given region is partly determined by the elevation of the surrounding terrain. On Planet, the prevailing winds always blow from west to
east. This means that the westward exposure of a ridge or mountainside catches more airborne moisture—the effective rainfall increases on that side.
However, little moisture reaches the eastward slope, so the rainfall decreases
on that side. A great mountain range may be lush and green on the western
side, but will be arid desert on the eastern side.

PLANET

C H A P T E R

3

You can learn to exploit this pattern by raising and lowering terrain with your
former units to create favorable rainfall conditions for yourself or unfavorable
rainfall for an opponent (see Terraform Menu, p. 46).

NATIVE LIFE
Planet has been teeming with life since eons before the arrival of humanity.
Individual specimens of Planet’s indigenous species seem simpler than analogous Earth life, but appearances can be deceiving. Much of Planet’s plant and
animal life is tied together in a grand symbiotic relationship, far more intricate
than any comparable system on Earth. Truly the whole is greater than the sum
of its parts. For more information on the native ecology of Planet, see
Planetography, p. 216.

FLORA
Though there are many different species of plant life, the dominant form is
the crimson, fantastically shaped xenofungus (or “fungus”), which covers vast
tracts of the surface. Its near cousin, sea fungus, is equally ubiquitous in
Planet’s oceans and seas.
Fungus squares (squares with fungus in them) can not be used for bases, tend to
spawn mind worm boils (see Fauna, p. 40), and they are difficult to move through.
However they do have one useful property—a ground or sea unit can hide in a fungus or sea fungus square, and is invisible to detection by all other factions unless
they actually try to move a unit into the square or have sensor arrays nearby (see
Terraform Menu, p. 46). Also, units attacked while in fungus get a defensive
bonus, unless the attacking unit is itself native life (either human-bred or “wild;”
see Fauna, p. 40), in which case the attacking unit gets an offensive bonus.
As your knowledge of Planet expands, you discover ways to extract useful
resources from fungus squares (see Resource Production Table, p. 52). You
can also overcome many of the inconveniences of fungus squares by enhancing your Planet rating through Social Engineering (see Social Factors, p. 141),
allowing easier movement through fungus.

Bases and enhancements cannot be built on xenofungus squares, but the
resources of the fungus itself can be harvested. As your terraforming technology improves, you acquire the ability to clear, and even to cultivate xenofungus. Fungus can be planted to create defensive barriers, or simply for the
resources it yields.

FAUNA
The dominant animal life of Planet is the mind worm, a horrid-looking little
parasitic carnivore about 10 cm long. A single mind worm is a dangerous pest,
able to burrow into a human brain and devour it, while the victim succumbs
to violent delusions or dangerous fantasies, or lives out his deepest terrors.
Many theories have been advanced to explain the psychoactive nature of these
attacks but none have been experimentally validated.
Far worse than a single worm, mind worms are known to form vast mobile colonies,
called “boils,” which can overwhelm a military unit or a whole human base.

40

In addition to the land-based boils, there is also an aquatic vector for mind worms
called the Isle of the Deep. This floating terror can attack ships at sea. It can also
attack coastlines, spitting up mind worm boils on shore. Even an airborne vector,
poetically dubbed the Locusts of Chiron, haunts Planet’s stratosphere.
All three mind worm vectors go through a lifecycle. Seven different phases of
growth for each vector have been identified (See Morale/Lifecycle, p. 87). The
larger and more mature a boil, the more dangerous it is.
As your technology advances and your knowledge of Planet increases, you
might acquire the ability to grow native life-forms and place them under your
control for use as weapons. You may also acquire the ability to enslave wild
mind worm boils into your service.

TERRAIN
The fantastic vistas of Planet offer more than alien beauty. Planet provides an
endless variety of both gifts and pitfalls for the human settlers.

RIVERS
Since the dawn of human history, rivers have been the arteries of civilization.
This remains true on Planet. If a river runs through a square, it delivers a +1
bonus to energy production. Rivers also tend to increase the moisture of the
squares they run through or by. Rivers start from an underground source and
follow the contours of the land down to the sea. With the proper technology
you can tap into underground aquifers and create new rivers.
Rivers can also be used as natural roads. A unit can float up or down three
river squares for every one square of normal movement it possesses.

OCEANS

41

There are three types of ocean terrain (corresponding to the three elevations
of land terrain): ocean shelf, ocean, and ocean trench. With the proper technologies and equipment, ocean shelf squares can be improved, and aquatic
bases can be established there. Ocean and ocean trench squares can not support bases or be enhanced.

RESOURCE SPECIALS
The ecology of Planet is complex, and a few regions produce significantly more nutrients, energy or minerals than would be expected from their
moisture, elevation or rockiness. These special squares are indicated by
icons, indicating the type of resource that is increased in that square.

UNITY PODS AND MONOLITHS
Before the Unity was destroyed, it released the Colony Pods of the seven factions and scores of robotic “seed pods,” carrying vital supplies and technology for humanity’s conquest of the new world. Unfortunately, because of the
chaos in the last hours of the Unity, these pods were scattered at random over
Planet’s surface.
Many of the Unity pods became infested with indigenous life-forms and
opening them unleashes fungal blooms or mind worm boils. A few others react
unpredictably with Planet itself, triggering massive earthquakes. The majority,
however, continue to hold valuable resources such as units and information
from old Earth.

42

Far more mysterious are the monoliths, relics of a mysterious intelligence that
visited or inhabited Planet long before humanity’s invasion. The monoliths
possess amazing psycho-technical powers. They can completely repair units
that are damaged and even make improvements to those units’ performance.
However, a monolith can enhance only so many units before its mysterious
power is exhausted and it ceases to exist.
Monolith squares yield two of each sort of resource, regardless of the underlying terrain (until the monolith disappears).
Other relics of the past are the alien artifacts—mobile machines that seem to
be a form of computer. Artifacts can be linked to Network Nodes to discover
new technologies, or their power can be tapped to hasten the completion of
Secret Projects.
Most of the time, monoliths and alien artifacts are indistinguishable from
Unity pods to long-range sensors. Only by actually sending a unit into the
square to open the pod can it be determined if the pod is a useful gift from
the Unity, an alien relic, or a disaster waiting to happen.

PLANET

FORESTS
One of the fundamental advantages of formers is their ability to plant forests
of terrestrial vegetation on the more inhospitable regions of Planet. Forests
provide a small yield of nutrients and minerals, while doing no damage to the
ecology of Planet (in fact, forest can actually offset ecological damage from
enhanced squares). Over time, forest squares expand into adjacent undeveloped squares. When a forest is harvested—that is, when any enhancement
other than a road is built on it—you receive a one-time bonus of +5 minerals.
Planting forests is an excellent method of deriving benefit from arid terrain,
particularly early in the game before some of the more advanced terraforming
options are available.

FUNGUS
The ubiquitous xenofungus can produce resources when you discover the
appropriate technology:
• Centauri Ecology gives you one nutrient per fungus square (per turn).
• Centauri Meditation gives you one energy per fungus square (per turn).
• Centauri Genetics gives you one mineral per fungus square (per turn).
• Centauri Psi gives you one more nutrient per fungus square (per turn).
• Secrets of Alpha Centauri gives you one more energy per fungus square
(per turn).
• Terraformers can plant xenofungus after the discovery of Ecological
Engineering; sea terraformers can plant sea fungus with this discovery.

LANDMARKS
Landmarks are giant natural wonders of Planet, the most important geophysical features of the world. You might encounter any of the following.
Freshwater Sea. The richest aquatic region on Planet provides +1 nutrient per square.
Garland Crater. Some thousands of years ago, a massive object crashed into
Planet, leaving this vast crater. The rare and valuable remnants of the original
object remain in the crater, giving the squares inside a +1 mineral bonus.
Geothermal Shallows. A whole field of underwater geysers underlies this
coastal shelf, providing +1 energy per square.
Great Dunes. The largest, most unforgiving desert on Planet. The Great Dunes
provide no bonus resources, and are in fact a remarkably inhospitable place.
Monsoon Jungle. This is an anomalous expanse of thick and curiously earthlike
vegetation. The rich soil of the Monsoon Jungle yields +1 nutrient per square.

44

Mount Planet. This enormous volcano is active, but its slopes provide a +1
bonus of both minerals and energy. The enormous crater at the top fills a
whole square with lava.
New Sargasso. This is the largest naturally occurring growth of sea fungus on
Planet. It provides no special bonus, other than the resources that can be harvested from the fungus itself.
Pholus Ridge. The geothermal energy unleashed by the clash of two of
Planet’s tectonic plates produces +1 energy per square along Pholus Ridge.
Sunny Mesa. This extensive highland offers no special resource bonuses, but
its elevation makes it naturally excellent for harvesting energy.
The Ruins. A vast and ancient ring of monoliths embedded in thick xenofungus, it has no special resources, other than the monoliths themselves.
Uranium Flats. This savanna is particularly rich in heavy elements that provide
+1 energy per square.

HOW TERRAIN AFFECTS MOVEMENT
A unit’s current movement points are displayed in the status view. As the unit
moves, this number decreases as movement points are used up.
Certain terrain types impede normal movement (these penalties have no effect
if moving across the square on a road or mag tube).
Rocky and forest squares each cost two movement points to cross, while sea fungus squares drain three movement points (however, these squares can always be
entered by any unit having at least one full movement point remaining).
Trying to enter a land fungus square (successfully or not) always ends your
unit’s movement, unless the unit is a mind worm boil, or your faction possesses the Xenoempathy Dome Secret Project.
Rivers are important in planning movement over undeveloped terrain, because
of their ability to triple a unit’s normal move.
Terrain has no effect on the movement of air units.

HOW TERRAIN AFFECTS COMBAT
Terrain can, in specific situations, provide crucial advantages in combat to
savvy commanders and deadly pitfalls to the unwary.
The important tactical ability of xenofungus to provide concealment has
already been discussed (Flora, p. 39).
Artillery units (see Artillery Combat, p. 100) get an offensive bonus of +25%
per level of altitude from which they are attacking.
Mobile units in smooth or rolling terrain get a +25% offensive bonus, reflecting their ability to make the most of their agility.
Any unit in rocky terrain gets a +50% defensive bonus.
Any unit in xenofungus gets a +50% defensive bonus, unless it is being attacked
by a native life-form (either human-spawned or “wild”) in which case the unit
gets no defensive bonus, but the native life-form gets a +50% combat bonus.

TERRAFORMING AND ENHANCEMENTS
Terraforming literally means “to make earthlike.” It is the art of maximizing
resource production in a given area, making that square more hospitable to
human life. It involves building technological enhancements to the square or,
in extreme cases, actually changing the terrain itself. Terraforming operations
must be carried out by former units, which become available upon discovery
of Centauri Ecology.

TERRAFORM MENU

46

Terraforming actions are listed on the Terraform menu. Some actions on the
menu require the discovery of certain technologies before the action becomes
available; you see only the options allowed by your current technology on the
menu. If an action is possible, the menu indicates the estimated time in turns
required to complete it. The construction rates listed below are normal values
and decrease as your terraforming technology and equipment improves. Note
that the longer an enhancement takes to build, the more ecological damage it
causes (see Ecological Risks, p. 54). Also, if you have the Simple menu option
selected (see Game Menu, p. 29), you may not get all of these choices.
SQUARE ENHANCEMENT LIMITATIONS
Terraformers may construct facilities in individual squares to enhance the
resource output of that square or to enhance the performance of the square
in other ways. In general, a square may contain a road or mag-tube, a
farm/soil enricher, and one additional enhancement. Building an enhancement
in a square that contains any enhancement other than a farm (or soil enricher) and road (or mag tube) destroys the earlier enhancement.
CULTIVATE FARM/KELP FARM F

RATE 4

A farm increases nutrient production by one; kelp farms (that is, farms in the
ocean) increase nutrient production by two. Farms can be built only on land
squares that are not rocky, occupied by xenofungus, or contain a monolith. A
kelp farm may be built only on ocean shelf squares.

PLANET

C H A P T E R

3

Building a farm requires Centauri Ecology. Building a kelp farm also requires
Doctrine: Flexibility.
CONSTRUCT SOIL ENRICHER F

RATE 8

Enrichers may be built only on land squares containing farms. They increase
the nutrient production of the farm by one.
Requires Advanced Ecological Engineering.
CONSTRUCT MINE/MINING PLATFORM M

RATE 8

Mining increases mineral production by +1 in flat or rolling squares and +2 in
rocky squares, but they reduce nutrient output by one if the square would
ordinarily produce more than one. A road in a mined rocky square adds an
additional +1 to the square’s mineral output. Mining platforms increase mineral production by +1 in ocean squares until the discovery of Advanced
Ecological Engineering; they add +2 minerals thereafter. Mines cannot be built
in squares occupied by xenofungus or a monolith. Mining platforms may be
built only on ocean shelf squares.
Building a mine requires Centauri Ecology. Building a mining platform also
requires Doctrine: Flexibility.
CONSTRUCT SOLAR COLLECTOR/TIDAL HARNESS S
RATE 6 (+2 IN ROCKY)/4 (TIDAL HARNESS)
A solar collector (or a tidal harness on an ocean shelf) increases energy production. Solar collectors produce one energy per level of altitude (see
Energy/Elevation, p. 38), while tidal harnesses produce +2 energy on ocean
shelf squares. Solar collectors cannot be built in squares containing xenofungus or a monolith.
Building a solar collector requires Centauri Ecology. Building a tidal harness
also requires Doctrine: Flexibility.

PLANT FOREST sF

RATE 4

A forest of terran trees provides a limited but steady supply of nutrients and minerals, regardless of the underlying terrain. Forests spread to adjacent undeveloped
squares over time. Forest can not be planted in squares containing enhancements
other than a road or mag tube. Tree Farm and Hybrid Forest facilities increase the
resources available from forest squares inside the base’s production radius.
BUILD ROAD R

RATE 1 (+1 FOR RIVER, +2 FUNGUS,
+2 FOREST, +1 ROCKY, CUMULATIVE)

Roads speed movement at a rate of three road squares for every one square of normal movement. Roads can be built only in land squares devoid of xenofungus until
the discovery of Centauri Empathy, which allows roads to traverse xenofungus.
BUILD MAG TUBE R

48

RATE DEPENDS ON TERRAIN

Mag tubes are the heavy transit system of the future, utilizing magnetic forces
to push passenger and cargo modules through a vacuum tube at near hypersonic speeds. Movement by mag tube is free, allowing a unit to move from any
square with a mag tube to any other square connecting to that mag tube, as
long as that unit has movement points remaining. Mag tubes may be built in
any square containing a road.
Requires Monopole Magnets.
CONSTRUCT BUNKER K

RATE 5

Bunkers are defensive fortifications that can be built on any land square. They
increase the defensive strength of all units inside them and limit the effects of
collateral damage (see Damage, p. 103).
Requires Advanced Military Algorithms.

An airbase is a ground facility outside a base where air units can land safely,
refuel, repair, and take off again.

CONSTRUCT SENSOR ARRAYS O

RATE 4

Sensor arrays allow you to see everything within a two-square radius (including
units hiding in fungus). Additionally, a sensor array grants a defensive bonus to
your units within its two-square radius. The ownership of a sensor array is
determined by the borders of your faction. If your borders move, placing the
array outside your boundaries, it may come under control of a new faction.
REMOVE FUNGUS F

Condensers collect atmospheric moisture for use in irrigation. A condenser acts
as a farm, but also increases the moisture level of every square within a twosquare radius by +1 (if the square already has a farm or soil enricher, the condenser replaces the farm or enricher.)
Requires Ecological Engineering.
CONSTRUCT ECHELON MIRROR sE

RATE 12

An echelon mirror links a series of mirrors into a network. Every square adjacent to the echelon mirror with a solar collector enhancement gets a +1 energy bonus. An echelon mirror may be built on any land square.
Requires Ecological Engineering.

CONSTRUCT THERMAL BOREHOLE sB

RATE 24

A thermal borehole is a shaft driven through the crust of Planet to tap directly into the geothermal energy and rare mineral resources of the inner core. A
thermal borehole yields +6 minerals and +6 energy, regardless of terrain type.
No other enhancements except roads and mag tubes may be built in the same
square as a thermal borehole, and they can only be built on land.
Requires Ecological Engineering.
DRILL TO AQUIFER Q

RATE 18

This command taps into a subterranean fresh-water source and brings it to the surface. The new water source immediately begins to flow to the sea, creating a river.
Requires Ecological Engineering.
TERRAFORM UP ]

50

RATE 12

You can raise the elevation of a square, raising surrounding squares proportionately, to create a natural slope. Terraforming up can increase energy production in the region and also provide a natural barrier to trap atmospheric
moisture (see Energy/Elevation, p. 38), increasing rainfall on the windward
slope and decreasing it on the downwind side. It can also be used to build land
bridges by raising the sea floor.
Requires Environmental Economics.
TERRAFORM DOWN [

RATE 12

You can lower the elevation of a square, dropping surrounding squares proportionately. Sea formers can lower coastal squares below sea level, turning
them into ocean shelf squares (this is done by lowering an ocean shelf square
to make it an ocean square—the slope created causes adjacent coastal squares
to drop below sea level). This destroys any enhancements and units in the submerged area, as well as any bases not protected by a Pressure Dome facility.
This option can be used to destroy land bridges.
Requires Environmental Economics.

FARM + SOLAR + ROAD csS
This command tells the former to build these three enhancements in the
square, in sequence, each at their normal rate. If used in a xenofungus square,
this command also clears the fungus. If terrain or previous enhancements prevent the completion of all three commands, as many as possible are executed.
FARM + MINE + ROAD CsM
This command tells the former to build these three enhancements in the
square, in sequence, each at their normal rate. If used in a xenofungus square,
this command also clears the fungus. If terrain prevents the former from carrying out all three commands, it executes as many as possible.

Forest facilities each increase nutrient production in forest squares within
that base’s production radius.
4 Your ability to extract resources from fungus improves as you acquire new

technologies. See Fungus, p. 43.
5 Also raises the raininess by one increment in a two-square radius.

10 Bonus is +1 until the discovery of Advanced Ecological Engineering, +2

thereafter.
11 Recycling tanks only affect the central base square.

ECOLOGICAL RISKS
If Planet’s complex ecology is not respected, it turns on an invader. Each technological enhancement constructed on any square in a base’s production
radius increases that base’s ecological disruption. In general, the more complex
an enhancement (i.e., the longer it takes to complete), the greater the damage
it causes. Also, the higher a base’s mineral production, the greater the chance
of ecological disaster.
Your ecological damage ranking, as shown on your base screen (see Data
Readout, p. 73), gives the percentage chance on each turn that Planet will
react to your disruptions, in the form of uncontrolled fungus blooms that wipe
out all existing enhancements in a given square. The new fungal squares also
often spawn voracious native life-forms.

PLANET

C H A P T E R

3

Ecological damage can be minimized (or even eliminated entirely) through
Social Engineering (increase your Planet rating; see Social Factors, p. 141),
base facilities (Centauri Preserve, Temple of Planet; see Facilities, p. 64) and
Secret Projects (The Pholus Mutagen and others; see Secret Projects, p. 65).

RANDOM NATURAL PHENOMENA
Planet is a mysterious and complex system. It constantly produces new and
unexpected means to discomfit and endanger humanity, but it can also capriciously produce surprising blessings.
The influence of Planet’s suns and moons may provoke a burst of mind worm
activity, or solar flares may increase energy stores while disrupting diplomatic
communications, or you may discover an unexpected store of extra resources
near a base, or an alien plague may break out. The effects of random events
range from windfalls to disasters. Some events directly affect your faction, others affect other factions, and many affect all of Planet indiscriminately.
Some events happen instantaneously; others last for several years. Negative
random events can sometimes be avoided (for example, plagues are far less
likely to break out in bases with biology lab facilities), but most just have to
be ridden out, for better or worse.
The only thing that can be reliably said about natural phenomenon on Planet
is it’s always safest to expect the unexpected.
Random events can by turned off in the game configuration options.

COLONIZING PLANET
Your faction begins as a few huddled refugees in a single, makeshift encampment. It’s up to you to see that it grows into a self-sufficient, globally dominant society.

BASES
Your fundamental goal on Planet is for your faction to survive and thrive. Your
faction expands, in terms of size, power and influence, by building new bases.
These bases are each independent, self-contained ‘cities’—the centers of your
faction’s economic, military, technological and social progress. A base’s production radius extends up to 20 squares surrounding it, up to two squares
away excluding diagonals. It is from these squares that the resources are gathered for your faction’s consumption.

58

BASE MANAGEMENT: THE ESSENTIALS
Your bases produce several different types of items, all of which are used in
various ways to build your new society. To enter one of your bases, L on it in
the World View.
Base Governor is an intelligent manager that can control your base production for you. The governor can be set to one of four priorities—Explore,
Discover, Build or Conquer (see Governor, p. 69).
Citizens—the laborers and followers of your faction—populate your bases.
These citizens work the surrounding terrain to collect resources: nutrients,
minerals and energy.
Nutrients feed your people to keep them alive and functioning. Nutrients that
are not used directly for this purpose help to grow the base population.
Population growth is essential for a strong empire, since more people mean
more workers to collect resources.

COLONIZING

PLANET

C H A P T E R

Minerals represent all raw materials derived from Planet that are used for construction. They are used to build units (vehicles and equipment) and base
facilities (special buildings). They are also used to maintain units (provide
spare parts and so on) supported by the base.
• Units are mobile, and may be used for defense, exploration and conquest.
• Facilities increase the capabilities of the base that builds them. Certain oneof-a-kind facilities (see Secret Projects, p. 165) can be built only once but
benefit your whole faction. Most facilities have a prerequisite technology that
you must discover before you can build the facility (see Facilities, p. 64).
Energy is collected from the area surrounding your base, from rivers, or by
using solar collectors to harness heat (see Terraform Menu, p. 46). The energy you collect is allocated for use in three different areas of your bases:
Economy, Labs and Psych. (Note that Specialist citizens can increase energy
allotments in specific areas; see Citizens, p. 61.)
• Energy allocated to Economy is used to maintain base facilities; any excess
is placed in the energy reserves. Your faction’s economic power is measured
by the size of its energy reserves. These reserves are saved as “energy credits,” and can be used like money for base facility maintenance, commerce
between factions, or to expedite construction projects.

59

• Energy allocated to Labs speeds research into new technologies.
• Energy allocated to Psych helps maintain order and peaceful existence
inside your bases.
• See Energy Allocation, p. 117, for more details.

GETTING BASES
When you arrive on Planet, your first base is usually placed for you, depending
on your game setup options. Once your first base is established, you can build
colony pods to construct others, or acquire bases from other factions through
conquest (see Bases and Facilities, p. 104), Probe Team activity (see Mind

COLONIZING

PLANET

C H A P T E R

4

Control, p. 135), or diplomacy (see Diplomatic Contact, p. 127). There are two
types of bases: those established on land and those established in the sea.
• To build a land base, press B while a land colony pod is active. This establishes a new base on the square the pod currently occupies. Land bases cannot be established on rocky, fungus or monolith squares.
• Sea colonies can only be established by sea colony pods on ocean squares
without sea fungus.
Colony pods can also be used to increase a base’s population instantaneously—place a pod in an existing base, and press B to increase that base’s population by one.
Location, Location, Location

60

Your bases should be placed near good resources, with ample nutrients, minerals and energy available nearby. When founding new bases, remember that
green is good — the more green in an area (representing rainfall), the more
nutrients may be produced. Green areas of the map almost always make excellent base locations, particularly those that are near rivers, which generate additional energy and expedite the movement of units around the base.
Placing your bases in useful relationship to each other is a very important component of success in Sid Meier’s Alpha Centauri. Put your bases too close
together and they’ll cannibalize each other’s resources, limiting their growth and
economic power. If you spread them out too much, you’ll be wasting much of
Planet’s resources, as well as compromising your ability to defend your territory.

WORKING THE LAND
Each of your bases is a self-contained “city,” with an area under its influence
up to 20 squares surrounding it, up to two squares away. This is called its
“production radius” (see diagram).
Before your base can exploit the resources of any square in its radius, a citizen must be assigned to work it. If a base has a population of five, it can
exploit up to five squares in its production radius, in addition to the square

COLONIZING

PLANET

C H A P T E R

4

The base’s production radius is
defined by the area bordered
by the red line

it’s in (that square is automatically fully utilized, with no need of actually
assigning anyone to work it).
You can place your workers by hand (see Assigning Citizens to Work, p. 71),
or the base governor assigns citizens as he sees fit (see Governor, p. 69).

CITIZENS
The human citizens of your bases represent a resource even more vital than
energy, minerals or nutrients. While the base governor can handle much of the
day-to-day work of citizen allocation, ultimately it is up to you to assign your
citizens for the greater good of the faction. Note that each “citizen” represents
a thousand or more humans. There are four classes of citizens on Planet:
Workers, Talents, Drones and Specialists.

61

Workers are the salt-of-the-Planet, skilled workforce that keeps things
running along smoothly.
Talents are the cream that rises to the top of your society, your pool
of highly skilled professionals. Talents are created by facilities, Secret
Projects, certain specialists, and energy allocated to Psych (each two
energy units allocated results in one additional worker becoming a talent; see Energy Allocation, p. 117).
Drones are the unskilled, unsuitable and disgruntled among your people. They’re lazy troublemakers, and they all carry weapons. Drones
have a profound effect upon social order inside a base. See Drone
Riots, p. 63.

• Specialists do not work the outlying squares of the base to harness
resources. Instead, they work inside the base, adding directly to the base’s
Economy, Psych and Labs production (see Energy Allocation, p. 117).
Until the base has sufficient population to work every single square in its production radius, you have to create specialists (they don’t “just happen”).
Different types of specialists become available as your technology advances,
and some advances render certain specialists obsolete. A base of any size can
have doctor or empath specialists, but a base must have Population 5 before
it can create other types. To create a different specialist, L on a citizen’s icon
in the Base Control Screen.
The various types of specialist are:

62

• Technician. Technicians keep the base running at maximum efficiency,
adding +3 to the Economy allotment per technician in the base. They
become obsolete when you acquire Fusion Power technology, replaced by
Engineers.
• Doctor. A healthy population is a happy population. Doctors increase
Psych allotment at a base by +2 per doctor. Doctors are rendered obsolete by Centauri Meditation and are replaced by Empaths.
• Librarian. Librarians are an invaluable asset to research, providing +3
to Labs allotment per librarian. They require Planetary Networks, and
are rendered obsolete by Mind/Machine Interface, replaced by Thinkers.
• Engineer. A corps of engineers can optimize all of a base’s functions,
yielding +3 to Economy and +2 to Labs per engineer. They are acquired
along with Fusion Power technology, and they never become obsolete.
• Empath. Empaths have actually learned to use the psi potential of their
brains, providing +2 to both Economy and Psych per empath. They
require Centauri Meditation, and are rendered obsolete by Secrets of Alpha
Centauri, replaced by Transcendi.

• Thinker. Thinkers have maximized the computational capacity of their
brains and provide +1 Psych and +3 Labs per thinker. Thinkers require
Mind/Machine Interface, and become obsolete with Secrets of Alpha
Centauri, replaced by Transcendi.
• Transcend. The penultimate stage of human mental evolution, transcendi provide +2 to Economy, +2 to Psych, and +4 to Labs. They
require Secrets of Alpha Centauri and they never become obsolete.
GOLDEN AGE
If a base of size three or greater has no Drones, and the number of Talents is
equal to or greater than the number of Workers, that base enters a “Golden
Age.” For the duration of the Golden Age, the base’s growth rate and energy
production are both enhanced (equivalent to a +2 Growth, +1 Economy on
the Social Engineering screen; see Society Window, p. 136). The Golden Age
ends once there are more Workers than Talents, or if any Drones appear.

63

DRONE RIOTS
If the number of Drones in your population exceeds the number of Talents,
the result is a Drone Riot, which shuts down the base’s entire research and
production capabilities. If left unchecked, rioting Drones start to destroy facilities, and may even cause a base to defect to a rival faction.
To end a Drone Riot, you can move military units into the base to act as police
(the number of police needed is determined by your Social Engineering choices), adjust your Social Engineering to increase your Psych rating globally (see
Society Window, p. 136), or create Specialists to increase it locally. To avoid
Drone trouble in the long term, there are numerous facilities and Secret Projects,
such as Recreation Commons and The Human Genome Project (see Appendix
2), that increase your Psych rating or suppress Drone activity.
When your faction grows very large, you come to a point where Drone production and inefficiency both accelerate dramatically. Beyond this point, extra
Drones may appear due to the difficulty of managing a far-flung empire.

When you reach this threshold, your advisors remind you if you are about to
found a base that sends you over the limit; you can choose to continue or
abort. If you go past this point, make sure your social and economic choices
are arranged to support it.

UNITS
Units are mobile teams created for military, engineering, trade, exploration or
diplomatic purposes. There are land, sea and air units, many with special abilities. There are a multitude of different units that your faction can build as its
technological abilities grow.
There are five vital statistics (Movement Points, Attack Strength, Defense
Strength, Reactor and Morale) that determine how a unit rates in movement
and combat.

64

• Movement Points. The number of squares the unit can enter each turn,
assuming no external penalties or bonuses.
• Attack Strength. A measure of the unit’s ability to overcome a defender.
• Defense Strength. A measure of the unit’s ability to resist an attacker.
• Reactor. How much damage the unit can take before destruction. The reactor also affects the cost of a unit.
• Morale. A measure of the unit’s discipline and experience. There are seven
levels of Morale (see Morale/Lifecycle, p. 87), and it is the most important
factor in Psi combat (see Psi Combat, p. 102).

FACILITIES
Facilities are major public improvements to a base. A base builds facilities to
increase its efficiency, productivity and/or power. All facilities provide some
useful benefit to a base, but not all benefits are necessary to a given base at
a given time. Some facilities come with both benefits and costs and can do
more harm than good if placed where they’re not needed (punishment spheres,

COLONIZING

PLANET

C H A P T E R

for example, eliminate Drone problems but reduce Labs production). Most
facilities require an ongoing investment of energy credits to maintain, which
is taken from energy allocated to Economy.
A complete list of Facilities, including their benefits and costs, can be found
in Appendix 2, p. 163.
RELOCATE HEADQUARTERS
This build order (see Build Orders, p. 67) causes a new headquarters to be
constructed in this base. You can only have one headquarters for you entire
faction. When the new headquarters is completed, your previous one is disbanded. Headquarters provide essential coordination among the bases of your
faction, which keeps inefficiency low. Inefficiency results from increasing distance from your headquarters, so it’s usually good to maintain your headquarters near the center of your empire.

SECRET PROJECTS

65

Secret Projects are massive works requiring a great concentration of research
effort and a very long time to complete. The good news is that they provide
dramatic advantages to your faction.
Only one of each of the 32 Secret Projects can be built on Planet. The other
faction leaders do anything they can to complete a Secret Project before you
and claim its benefits for their faction. If a rival faction builds a Secret Project
you’re working on, you must transfer your research investment to some other
Secret Project, or allocate it to new construction.
If a base with a Secret Project is ever completely destroyed, that project—and
any ongoing benefits from it—are gone forever, for you and all other factions.
If a base with a Secret Project is captured, that Secret Project—and any ongoing benefits from it—become the possession of the capturing faction.
A complete list of Secret Projects can be found in Appendix 2, p. 170.

STOCKPILE ENERGY
If you don’t particularly need any new units or facilities from a base, but don’t
want to let its production capacity go to waste (or if your faction is strapped
for cash) you can order your base to Stockpile Energy. This causes the base to
immediately sell off every excess mineral it produces in exchange for energy
credits, which are then deposited in your energy reserves.

A TOUR OF THE BASICS
The Base Control Screen allows you to control your base to a minuscule level,
but if left alone the base can do a pretty good job of running itself. Most of
the time, you’ll be checking the Base Control Screen just to take a quick look
at the current status of a base—what it’s building, how its citizens are doing,
and so forth. Below is a quick guide to reading the most important data from
the Base Control Screen (you can also : on any part of the Base Control

This graph shows how your base is growing. When your nutrient tanks fill up (all the squares are bright), the population of
the base increases by one citizen and the nutrient tanks empty.
Conversely, if your base isn’t producing enough nutrients to
support all its citizens, nutrients are drawn from the tanks. If the tanks empty
and you still have a nutrient shortfall, you lose a citizen to starvation.

GOVERNOR
If you’d rather not worry too much about the year-to-year operations of a particular base, you can put the Base Governor in charge, making it his responsibility to assign citizens to work and determine which squares to develop and
what projects to undertake. If you don’t like a decision that is made, you can
always overrule it.
To activate the governor, L any of the five buttons at the top of the Base Control
Screen. On lower difficulty levels, the governor is always active as the default.
The governor’s priorities are set depending on which of the five options you
select. (Once the governor is on, L on the active priority to turn the governor off.)
• Default. The governor pursues a strategy mixing growth and defense concerns. This is the automatic priority at difficulty levels where the governor
defaults to “on.” To activate the governor with default priorities, L on the
GOVERNOR button until only that button is lit.

69

• EXPLORE. The base devotes itself primarily to producing units to explore new terrain. New colonization (colony pods) and population growth are also priorities.
• DISCOVER. The governor maximizes Labs output, seeking to optimize the
speed of discovery of new technologies. It also emphasizes Secret Projects
and probe teams for intelligence gathering.
• BUILD. The base disregards most external concerns, concentrating on its own
growth, terraforming, and the creation of new facilities.
• CONQUER. The base goes on a war footing, producing primarily military units
and facilities with specifically military applications (perimeter defense, command center).

ASSIGNING CITIZENS TO WORK
Your Resource Screen is used to control your base’s resource production.
If you L on any square currently under production, you reassign that
square’s worker to become a Specialist (see Citizens, p. 61). That square is
immediately taken out of production.
If you L on any square not currently in production, the governor selects a
Worker or Talent to begin working on that square. The governor selects a
square to abandon in favor of the new square.
If you want to reassign a Worker from one specific square to another, L on
the square you want to take out of production (to temporarily create a
Specialist), then L on the new square to reassign that Worker to it. You can
also drag and drop Workers from the population bar onto empty squares.
Say, for example, that you suspect the Hive is getting ready to launch an
invasion of your territory. This reassignment function allows you to order a
crucial border base to live off nutrient tanks for a few turns while your
Workers maximize mineral production to complete a Perimeter Defense
without dipping into energy reserves.

71

If you L directly on the base square itself, the governor selects assignments
for all available workers, with a view towards (a) meeting the base’s current
resource needs first, and (b) maximizing production (according to the governor’s current priorities, if any).

Likewise, if your base is not bringing in enough nutrients to support itself, the
projected decrease in the tanks is shown by bright squares outlined in red.
When the tanks are completely emptied, the base loses one unit of population
to starvation. The base continues to lose one citizen per turn thereafter, until
it reaches a population that can be supported by current nutrient production.

• OK. Accepts the current projects and closes the Production Readout.

SWITCHING PRODUCTION
If you decide to halt production on a Secret Project, unit or facility before it
is complete and switch production to something new, you lose some of the
minerals you have accrued towards the original project. The sole exception is
switching from one Secret Project to another Secret Project, which does not
forfeit any minerals.

79

You will need to switch production if a Secret Project you have been working
on is completed by another faction first. If you stop a Secret Project, you can
roll all of your investment into another Secret Project.
HOW MUCH DO YOU LOSE?
If you make any other kind of switch, you lose 50% of your investment after
the first 10 minerals. This applies if you roll your investment from a Secret
Project into anything but another Secret Project, or if you transfer your investment in a unit or facility to any other unit or facility.
The first 10 minerals that you invest transfer with no loss. All investment over
10 minerals is cut in half. For example, if you have invested 8 minerals, all 8

COLONIZING

PLANET

C H A P T E R

4

minerals transfer, with no loss. If you have invested 40 minerals, the first 10
transfer, as do half of the remaining 30: you transfer 25 (that is, 10 + 30/2)
and you lose 15 (30/2).
If the transfer more than pays for the designated purchase, up to 10 of the
remaining minerals are held over for your next production, with no additional loss. Anything over 10 minerals is lost completely. Continuing our example,
where you have transferred 40 minerals (which are reduced to 25 minerals in
the transfer): if you transfer those 25 minerals to a purchase that only requires
8 minerals, 10 of the remaining 17 minerals (25 - 8) are held over and can be
applied to yet another purchase. The last 7 minerals are lost completely.
Up to 10 minerals can be held over between production orders even when
orders are completed normally. For example, if you have a base producing 23
minerals, and it has 5 minerals left to create a unit, on the next turn it creates
the unit (expending 5 minerals), carries 10 minerals over to the next production orders, and the final eight minerals are lost completely.

80

UNITS
Units are those elements of your faction—people and equipment—that actually
go out upon the face of Planet and do things like fight, explore and discover.
At the most basic level there are three kinds of units in Sid Meier’s Alpha
Centauri—land, sea and air units. Land and sea units are basically selfexplanatory—land units can only move on land squares, sea units on sea
squares. Both types are subject to movement restrictions from fungus and
other obstructions (see How Terrain Affects Movement, p. 44). A unit’s chassis determines what kind of unit it is (see Chassis, p. 83).
Air units are a special case. They have no terrain restrictions at all, but most
have a limited range. Air units carry only enough fuel for two turns of operations. The unit must replenish its fuel every other turn at a friendly base or airbase, or it runs out of fuel. The unit’s movement is displayed as a split number, for example, 12/24. The first number is the amount of moves remaining

COLONIZING

PLANET

C H A P T E R

4

this turn, and the second number is the total movement available over two
turns. A yellow or red split number indicates that this aircraft should be heading for a nearby base to avoid the risk of a crash.
Choppers are air units, but they don’t run out of fuel. Instead, they need
ongoing maintenance when in regular use. If a chopper does not end its turn
in a base or airbase, it takes a small amount of damage. (Damage is repaired,
over time, when the chopper is at a base or airbase.) This damage weakens the
chopper in combat, and can result in the chopper falling apart and crashing,
if allowed to continue too long without repairs in a base or airbase.

DESIGNING UNITS
As you advance technologically, you are given the option of using units predesigned by your designers, or of designing your own units, using a fixed
assortment of components. Custom-designed units allow you to specifically
tailor units to your personal mission needs and also make full use of some of
the more exotic special abilities. New components are discovered in conjunction with many technology advances (see Special Abilities Table, p. 183). For
example, High Energy Chemistry allows you to build with plasma steel armor
and nerve gas pods.

81

To design a new unit, press U, or access the Design Workshop Screen from
the HQ menu or the Production Readout.
Units are made up of up to six components:
• Chassis
• Armament
• Armor
• Reactor
• Special Abilities (up to two)

COLONIZING

PLANET

C H A P T E R

PROTOTYPES
Any time you order construction of a unit with untried components, that unit
is a prototype. If you have already built a laser crawler and an impact rover,
your first laser rover (which consists entirely of components found in the previous units) would not require a prototype. But if you discovered the missile
launcher and decided to build a missile rover, the new missile launcher component would make your first missile rover a prototype.
Prototypes require a great deal of research and development. Therefore, a prototype costs 50% more minerals to complete than subsequent units of this type
will. On the upside, all prototype units get a +1 to morale, since new technologies are usually put in the care of elite forces. Note that the Spartans do
not have to prototype new units due to their expertise with military hardware.
OBSOLETE UNITS

82

As new versions of components are researched, old ones become obsolete.
Units with obsolete components disappear from your Production Readout and
are replaced by the newer models. You can also declare units of a given kind
obsolete from the Design Workshop.
UPGRADES
When an old unit becomes obsolete, you don’t have to junk it or let it wheeze
around. When you discover a new version of a component, you are given the
option of upgrading all the units that discovery has made obsolete. You must
pay an energy charge for each obsolete unit in your possession in order to
upgrade them. If you don’t want to spend the energy to upgrade all your units
of a given sort at once, you can also upgrade one at a time, using the Upgrade
command—csU on the Action menu (see p. 92). (Note that you can
also disband a unit at a base, and receive half its original cost in minerals.)

CHASSIS
The Chassis of the unit determines two vital characteristics: whether the unit
is a land, sea or air unit; and its basic movement rate (see Movement, p. 90).
A complete list of Chassis types and their associated values can be found in
the Units Table, p. 175.

WEAPON
The unit’s weapon type determines its offensive firepower. A list of armaments
and their associated values appears on the Armament Table, p. 177.
An important special weapon is the Psi attack, described under Psi
Combat, p. 102.
Non-combat units (colony pods, terraformers, and the like) can take unique
abilities in their weapon slot—for example, transport modules, colony modules
or probe team equipment.

83

ARMOR
A unit’s armor determines its basic defense strength. A unit is not required to
have armor—even unarmored units get a small intrinsic defense strength.
A complete list of armor types and their associated values appears on the
Defenses Table, p. 180.

REACTOR
Reactor Power determines how much damage the unit can actually take before
it’s destroyed. Also, more advanced reactors actually reduce the costs of units.
A complete list of reactors with associated values appears on the Reactors
Table, p. 182.

SPECIAL ABILITIES
You can also endow your units with special abilities to fulfill specific tactical
needs. Some are geared towards attack, some to defense, and some are more
esoteric. If, for example, the Gaians are attacking your faction with an invasion force of mind worms, you might want to counter with a force of units
equipped with the Hypnotic Trance special ability, which gives the units a
+50% defensive bonus against psi attacks. In the early stages of the game you
can have no more than one special ability per unit type, but you acquire the
ability to mount two special abilities on the same unit with the discovery of
Neural Grafting.
A complete list of special abilities, with descriptions, can be found on the
Special Abilities Table, p. 183.

CUSTOM UNITS

84

If you decide to build your own units to use in addition to the pre-designed
units, you should know that the cost factors (given in Appendix 2) are not
simply additive. The cost for a custom unit with many advanced features is far
above the sum of its component prices. In fact, often if you take a “super unit”
and tone down just one or two components a notch or two, you will find that
you can now afford two or more of the slightly more modest units for the
same price you’d have paid for a single super unit. Consider designing two different types of units which complement each others’ weaknesses rather than
trying for one unit with no weaknesses. Advanced reactors make the unit more
efficient and actually reduce its cost, so an advanced reactor can make more
sophisticated units more affordable.
Many special abilities are, for obvious reasons, unavailable on units of a certain type. Aircraft, for example, cannot mount heavy artillery, while combat
units cannot mount a heavy transport module.

BUILDING UNITS
Custom-designed units
can be created in the
Design Workshop, which
can be accessed with U,
or from the HQ menu or
the Production Readout.
You can get a head start
in designing the type of
unit you want by either
selecting a specific unit to
modify, or by using a vehicle preset.
Specific unit designs are displayed in the long bar at the bottom of the screen.
This bar contains all the unit types currently designed and in production, and
can be scrolled using the arrow buttons at either end of the bar. Units which
are obsolete to your faction, but still in production, are marked “obs.” Placing
your cursor over any of the units in the bar displays information about that
unit in the lower left window. L on the unit to place it in the design screen
for modification.

85

VEHICLE PRESETS
Vehicle presets are up-to-date versions of various vehicle types in a number of
categories:
• Garrison. Defensive units designed to protect bases and fortifications.
• Infantry. General-purpose combat units particularly useful for attacking bases.
• Artillery. Units with long-range fire capability (see Artillery Combat, p. 100).
• Tank. Mobile units useful for attacks in open terrain.
• Scout. Lightly armored, very fast units.

• Naval. Combat ships.
• Transport. Non-combat ships designed to carry goods or personnel.
• Air Assault. Heavy bombers.
• Air Defense. Fighters designed to intercept and engage other aircraft.
• Chopper. Rotary-wing aircraft.
• Missile. One-use air units—once they hit their target, they are destroyed.
• Buster. Missile units capable of annihilating bases and the surrounding terrain.
• Paradrop. Units capable of performing airdrops and orbital insertions (see
Drop Pods, p. 91).
• Amphibious. Units capable of attacking directly from ship to shore, or
attacking sea bases from land.

86

DESIGN WORKSHOP
Once you’ve chosen a starting point, you can make the specific modifications
you desire. The large round window shows the unit in development, its current stats and a working name based on its components. It also displays the
unit’s cost, and a prototype cost if a prototype is necessary. This window is
surrounded by six readouts showing the six component slots. L on a slot to
select the component you want for your custom unit.
Control Buttons. There are seven control buttons below the Design Window.
They are:
• APPLY. If a new unit type has been created, it’s placed in your Production
Readout.
• DONE. Exits the Design Window. If a new unit type has been created, it is
placed in your Production Readout.
• RENAME. Allows you to give the unit type a name other than its working designation.

• OBSOLETE. The unit type is removed from your Production Readout.
• UPGRADE. Upgrades all units of this type to a superior design, if one is available.
• CANCEL. Closes the Design Window with no changes.
• RETIRE. Disbands all units of this type, and removes the unit type from your
Production Readout.

BASIC UNIT TYPES
Certain unit types begin the game already designed and prototyped:
• Colony Pod
• Basic Formers and Sea Formers (Super Formers can be modified)
• Scout Patrol
• Transport Foil and Supply Crawler

87

• Probe Team
• Native life-forms—mind worms, Isles of the Deep, Locusts of Chiron
• Alien Artifact (cannot be built, must be found)
• Unity units—Unity Rover, Unity Scout Chopper, Unity Foil (cannot be built,
must be found)
As your technology advances you may want to design newer, more powerful
units to fulfill these roles.

MORALE/LIFECYCLE
One of the most important aspects of any given unit is its morale—its overall
discipline and experience. There are several levels of morale. Morale for native
life-forms (mind worms, Isles of the Deep and Locusts of Chiron) is called lifecycle level, since a native unit’s morale reflects not only the experience of its
human handlers, but also its physical maturity.

The importance of morale in combat cannot be overstated. Each level of morale
gives a +12.5% bonus to the unit, in both offensive and defensive combat.

88

The most common manner in which a unit’s morale is increased is for it to survive combat and be promoted, but there are other ways to increase morale of
both individual units and of your military in general. These include:
• Monoliths have been known to increase the morale of individual units (see
Unity Pods and Monoliths, p. 42).
• Base Facilities can increase the morale of units made at that base.
Command Centers provide +2 to land units, Naval Yards provide +2 to sea
units, Aerospace Complexes provide +2 to air units, and Bio-enhancement
Centers provide +2 to all units. Facilities provide morale bonuses only to
units made after the facility’s completion; they do nothing for units already
existing at the time they’re built.
Several base facilities also increase the lifecycle of any native units bred. The
following confer +1 lifecycle bonus: Biology Lab, Centauri Preserve and
Temple of Planet.
• Secret Projects
• Social Engineering (see Social Factors, p. 141)

PLANET

HOME BASE, SUPPORT AND PACIFISM
The base that builds a unit is that unit’s home base. Units taken over by probe
teams, or wild mind worms “tamed” by your faction, become the responsibility of the base geographically closest to the spot where the unit was acquired
by your faction. A few units, such as those acquired far away from any base,
do not require a home base at all.
You may change a unit’s home base by moving that unit to a new base and
selecting Set Home Base (cH) from the Action menu. That base now supports the unit. The home base must pay the unit’s support cost, if any.
A support cost represents the cost of keeping a unit equipped and staffed. The
cost for a given unit may be zero or one mineral per turn (as determined by your
faction’s support rating; see Social Factors, p. 141). It is subtracted from minerals collected at the home base. If you find that a base cannot build new orders
as quickly as it used to, it’s often the result of too many minerals used for support of existing units. In this case, try disbanding old or obsolete units (See
Design Workshop, p. 86) so more minerals can go towards new production.

89

If your faction has a Police rating less than 2 (see Social Factors, p. 141), it is
considered to be Pacifist. When a pacifist faction creates a unit and stations
it anywhere outside its own territory (see Territory, p. 131), additional drones
(see Citizens, p. 61) are created at the unit’s home base (representing social
discord). On the base screen, the Forces Supported Readout shows the effects
of pacifism as a peace symbol, one for each Worker that has become a Drone
because of a unit outside its territory.

MOVEMENT
There’s more to getting your units where they need to go than just pushing
them around the map. Moving a unit is an operation all to itself, and there are
several essential principles you must keep in mind (plus a couple of exotic
options that you can try).
In the absence of external bonuses or penalties to movement (see How Terrain
Affects Movement, p. 45), a unit can move a number of squares equal to its
movement rating. Land units can move only from one land square to another, and sea units can only enter sea squares.

ZONES OF CONTROL

90

Bases and land and air units exert a “zone of control” that restricts movement
in their immediate vicinity, reflecting the difficulty of moving with an enemy
nearby. A zone of control affects the eight squares immediately adjacent to a
base or unit.
A zone of control has no effect on units of the same faction, units of factions
sharing a Pact of Brotherhood, sea units, air units, or probe teams.
RESTRICTIONS TO MOVEMENT
A unit cannot move directly from one enemy zone of control to another. A unit
can enter or exit an enemy zone of control freely as long as both squares are
not enemy controlled.
A unit can always move
into a base square, or
into a square containing at least one friendly
unit, regardless of
zones of control.
Probe team units always
ignore zones of control.

COLONIZING

PLANET

C H A P T E R

4

An advanced special ability—the Cloaking Device—makes a unit effectively
invisible to the enemy, thereby allowing it to ignore zones of control.

DROP PODS
Drop Pods are a special ability component that allows units to make airdrops
or orbital insertions. Discovery of Mind/Machine Interface allows construction
of Drop Pods. Any unit with Drop Pods may make airdrops. Once you discover Graviton Theory or build the Space Elevator Secret Project, any unit with
Drop Pods may make an orbital insertion.
To perform an airdrop or orbital insertion, the Drop Pod unit must begin in a
friendly base or airbase, and may not have moved already this turn. At the drop
command, I, a parachute icon appears and you can L the destination square.
The destination square may be up to 8 squares away and can not contain
enemy units or bases. The Drop Pod unit moves instantly from the start square
to the destination square. Units take damage from airdrops—20% damage, or
26% if the unit has a singularity reactor.

91

If a unit tries to drop and then attack on the same turn, it receives a 50%
penalty to attack strength.
Orbital insertions are executed identically, but the drop can be made anywhere
on Planet.
An interceptor unit (see Air Combat, p. 101) stationed in a base within two
squares of the drop point prevents an air drop to that location.

ACTION MENU
The Action menu contains all the commands that you can give your units
(except for Terraforming commands, which are found on the Terraform Menu,
p. 46). Some of these options only appear if your unit is capable of performing that action at the moment (for example, a combat unit that is not in a
base will not see the Obliterate Base option).
CONSTRUCT BASE B
This command can only be carried out by a colony pod. The pod transforms
itself into a new base at its current location (if its current square is one on
which a base can be built; see Resources, p. 36).
OBLITERATE BASE B

92

This command can only be carried out by a combat unit (any unit with offensive armament) inside a base. It completely obliterates that base, putting all
the citizens to death and leaving nothing but bare terrain. This is an atrocity
(see Atrocities, p. 106), and results in severe repercussions from other faction
leaders. (Note that obliterating a base which you just conquered is considered
a worse atrocity than destroying one you built yourself—the other factions are
distinctly upset by any hint of “factional cleansing” on Planet.)
LONG RANGE FIRE F
Some units (notably artillery) can fire up to two squares away. To conduct long
range fire, select this command (your cursor changes to a target symbol) and
L on the square you wish to attack. If there are enemy units in the target
square you attack those units, and if there are no enemy units you attack
enemy terrain enhancements.
AIR DROP I
Orders a unit equipped with a Drop Pod to make an air drop or orbital insertion. When you select this action, your cursor changes to a parachute icon, and

you can select a square to drop to. See Drop Pods, p. 91, for a full explanation of air drops.
PSI GATE sI
Orders a unit to teleport from any base equipped with a Psi Gate facility to
any other of your bases so equipped. When you use this command a window
appears displaying all available destinations. Select the desired destination to
complete the movement.
CONVOY RESOURCES O
Orders a supply unit to deliver resources. It has two distinct functions:
• If the supply unit is outside a base, it delivers available resources from its
square to its home base each turn. Choosing this command brings up a menu
from which you select the resources you wish to convoy. The unit cannot
deliver resources from a square already being worked by a base’s citizens.
• If the unit is within a base, it convoys resources from its home base to its
current location every turn.

93

DESTROY ENHANCEMENTS D
Orders a combat unit or former to attack and destroy any enhancements in the
square it currently occupies.
DISBAND UNIT sD
Permanently destroys a unit, taking it completely out of play. If done at a base,
you get 50% of the original construction cost back. If the unit is outside a
base, you get the option to “Self Destruct,” which violently destroys the unit
while also damaging units in adjacent squares.
AUTOMATE UNIT sA

EXPLORE AUTOMATICALLY /
The unit, under its commander’s discretion, seeks out and explores uncharted
terrain.
PATROL P
This orders a unit to patrol back and forth between its current location and a
second square you select. Use this command, then L on the second square.
DESIGNATE BOMBING RUN B
This order designates an enemy base as a target for routine air attacks. The
unit attacks the base you select, returns to the nearest friendly base, repairs its
damage, then attacks again. The unit continues until its orders change or it is
destroyed.
GO TO BASE/SET AUTOFORWARD ROUTE G

94

Select “go to base” to issue orders to a unit you want to move towards a particular base. The unit goes to any of your bases by the most direct route possible (if it can’t actually reach the base it goes to the closest square). Selecting
this command brings up dialogue from which you select a destination.
When in view mode (see Map Menu, p. 32) and centered on a base, pressing
G allows you to set an autoforward route. This option commands any unit
without orders in one base to head to another that you select, setting up a
central rallying point for your troops. You may set autoforward routes for any
kind of unit.
GROUP GO TO J
This orders an entire group to go to a location you select (see Assemble Group,
facing page). Use mouse movement (see Mouse Movement, p. 21) to L and drag
to the group’s final destination, then use this command before releasing. The line
showing the proposed route to the destination changes from green to yellow. If
you have not assembled a group, all units in the current square are moved.

• Exclude units further than two squares away
• Exclude units with hold and sentry orders
• Exclude automated and patrol units
• Exclude ground, sea, air, offensive combat, defensive combat, terraformer,
or probe team units.
• Exclude other units
Once you’ve established the parameters of your group, L ASSEMBLE AT CURSOR to

orders, CANCEL to exit the screen without taking action, or OK to assemble the
group on the square with the active unit.

base. See Home Base, Support and Pacifism, p. 89, for more on home bases.
ACTIVATE (MOVE NOW) A
Makes the unit under the cursor the active unit (see Active Units, p. 22). A

UNLOAD TRANSPORT sU

UPGRADE UNIT cU
This command only works if the unit can be upgraded (see Upgrades, p. 82).
At the command to upgrade the unit, you are told how much the upgrade
costs, and given the option of canceling or continuing. If more than one possible upgrade is available, you are asked to choose.
DESIGNATE DEFENDER cD

96

Allows you to select the unit in a stack that defends first in the event of an
attack on that square. Otherwise, the computer automatically selects the unit
with the highest defense strength as the defender. This command is useful if
you don’t want your best unit in a stack to take the brunt of the attack, preferring to keep it in reserve for a counterattack.
SENTRY/BOARD TRANSPORT L
The unit stands down to repair itself, while posting sentries and maintaining
a state of readiness. It stays in position and does not reactivate unless:
• it repairs itself to the maximum it can achieve under current field conditions
• an enemy unit enters an adjacent square
• it is attacked by artillery
If used in a base, this command causes the unit to automatically board any
transport that has room for it.

HOLD THIS POSITION H
The unit stays in its current position indefinitely. You must activate it directly

97

COMBAT
At some point, even for the most peaceful and enlightened faction, armed
conflict becomes inevitable. And, of course, if your faction is neither peaceful
nor enlightened—if you actually like going out and beating up on the enemy—
then armed conflict is not just inevitable, but essential.
Combat occurs when a unit tries to enter a square containing an enemy base
or unit. (Probe teams are the exception here—their options are much more subtle. See Probe Teams, p. 133.)
Combat is decided by totaling the attacker’s strength and the defender’s
strength. The probability of either side doing damage is equal to that side’s
portion of their combined strengths. (For example, if the attacker has an attack
strength of 10 and the defender a defense strength of 20, the attacker only
damages the defender once, on average, for every two times the defender
damages the attacker.) This process of assessing damage repeats until either

COLONIZING

PLANET

C H A P T E R

4

the attacker or defender is destroyed (the exceptions are artillery, p. 100, and
disengage, below). It is entirely possible for the winner of a battle to come out
severely damaged.
STACKED DEFENDERS
If a unit attacks a square containing multiple defending units, the unit with
the highest defense acts as the defender (unless you have designated another
unit in the stack as the defender; see Action Menu, p. 92). If the defender is
defeated, and the square is not a base or bunker square, the rest of the combat units in that square take collateral damage (that is, they each take a certain amount of damage, determined by the reactor of the attacking unit).
Non-combat units in a stack are destroyed along with the last combat unit in
the square.
DISENGAGEMENT

98

In combats where the defending unit is faster than the attacker (i.e., the
defender has at least one more movement point than the other), the faster unit
can disengage if the battle is going against it. When a unit disengages, it simply moves one square away from the attacker. This assumes, of course, that
the square into which the unit is retreating is not blocked by impassable terrain or an enemy zone of control (see Zones of Control, p. 90). A faster
defender automatically disengages when it has received 50% damage.
If the attacker has the ECM Jammer special ability, the defending unit can’t
disengage from combat, even if faster. Also, if the defender attacked in its
immediately preceding turn, it may not disengage under any circumstance.

COMBAT MODIFIERS
In addition to the strength of the units themselves, there are also external factors that can affect the outcome of combat. These take the form of percentage bonuses or penalties to the unit’s base score. For example, if a defending
unit has a normal defensive strength of 20, a +15% bonus would give it an
effective strength of 23.

COLONIZING

PLANET

C H A P T E R

SPECIAL ABILITIES
Many unit special abilities convey a bonus in combat (or inflict a penalty on
the enemy). See the list in Appendix 2, p. 183.
TERRAIN
There are several occasions where terrain directly affects the odds in combat.
• Artillery units (see Artillery Combat, next page) get a +25% bonus per level
of altitude if they are at a higher altitude than their targets.
• Mobile units in smooth or rolling terrain get a +25% offensive bonus,
reflecting their ability to make the most of their agility.
• Any units in smooth or rolling terrain get a +50% defensive bonus against
artillery attacks.
• A unit in rocky terrain gets a +50% defensive bonus.
• A unit in xenofungus gets a +50% defensive bonus, unless being attacked
by a native life unit (in which case the attacker gets a +50% offensive
bonus), or by a faction that has built the Pholus Mutagen Secret Project.

99

HASTY ASSAULT
Each time a land unit attacks, it drains one full movement point from the
unit’s total move. If you have less than one full movement point remaining
when you attack, that is considered a hasty assault, and it puts you at a serious disadvantage. If you have 2/3 of a movement point remaining, you lose
33% of your attack strength, and if you have only 1/3 of a movement point
remaining, your penalty is 66%. (Movement status does not affect defensive
strength.)
A hasty assault always drains any fractional movement you have remaining.
Sea units, air units and mind worms do not suffer the negative consequences
of making a hasty assault.

COLONIZING

PLANET

C H A P T E R

BUNKERS AND BASES
Bunkers and bases offer a +25% defensive bonus to units within them. They
also eliminate the effects of collateral damage. However, infantry gets a +25%
bonus when attacking a base.
SENSORS
Units within 2 squares of a friendly Sensor Array (see Terraform Menu, p. 46)
get a +25% defensive bonus.
AIRDROPS AND ORBITAL INSERTIONS
Drop units (see Drop Pods, p. 91) get a -50% penalty if they attack on the
same turn in which they make the drop.
NON-COMBAT UNITS

100

Unarmed units get -50% penalty defending against combat units. A unit is
considered “non-combat” if it has no weapon and no armor, so a former unit
with plasma steel armor does not get the non-combat penalty when attacked.

ARTILLERY COMBAT
Naval units and units with the artillery special ability are able to use the Long
Range Fire (F) command (see Action Menu, p. 92).
Unlike most combat, artillery combat (combat using the Long Range Fire command) does not continue until a unit is destroyed. Attack and defense
strengths of the units are compared only once, and (if the defender loses the
single round of combat) a point of damage is assessed against the defender.
This reflects the nature of artillery combat, which is basically firing blind to
harass and weaken the enemy. Note that land units can never be completely
destroyed by artillery fire, and units in a base or bunker can never be damaged
more than 50%, although repeated barrages will keep them from repairing
damage. Targeting a square with no units for an artillery barrage actually
attacks any terrain enhancments in the square.

COLONIZING

PLANET

C H A P T E R

4

ARTILLERY DUELS
An exception to this rule occurs when one artillery unit attacks another. In this
case an artillery duel occurs, as each unit focuses its fire on the other. Artillery
duels are to the death, just like most other combats, but they utilize attack
strengths only.
ARTILLERY COMBAT MODIFIERS
• Artillery units get a +25% bonus for each level of altitude (see Energy
(Elevation), p. 38) they are above the target.
• Land-based artillery gets a +50% bonus when attacking naval units.
• A unit in smooth or rolling terrain gets a +50% defensive bonus against
artillery attacks to represent maneuverability as a defensive measure against
artillery.

AIR COMBAT
There are two basic types of aircraft, bombers and interceptors. Bombers may
only attack bases and surface units; they cannot attack air units. Interceptors
can attack other air units, but are at a penalty when attacking surface targets.
Specifically, interceptors attack other air units at twice their normal offensive
power, but land and sea targets at only half normal strength. (Combat
between two interceptors is at normal odds.) Any unit can attack a chopper.

101

To attack needlejets in flight (i.e., anywhere outside of a base or an airbase),
a unit must have the Air Superiority special ability . Air units at bases and airbases are considered to be “on the runway,” and can be attacked by any unit.
Missiles are a special kind of air unit. They are one-shot “fire and forget”
weapons. Missiles are always destroyed after an attack, even if they win.
Air units can attempt to destroy enemy terrain enhancements by flying over
the enhancement and using the Destroy Improvement command (see Action
Menu, p. 92).

The Designate Bombing Run and On Alert commands (see Action Menu, p.
92) can also be used to automate air combat.
AIR COMBAT MODIFIERS
Air units receiving an artillery strike get a +100% bonus to defense strength.
(An artillery unit must have the Air Superiority special ability to attack air units.)

NAVAL COMBAT
Sea units can attack normally against other sea units and sea bases. Attacks
against bases and units on shore are handled as artillery strikes. (See Artillery
Combat, p. 100) A sea unit does not have to have the artillery special ability
to attack adjacent coastal squares.
NAVAL COMBAT MODIFIERS

102

Ships in a base square are considered to be “in port,” and defend at a -50%
penalty against land and air units (for a net penalty of -25%, after the +25%
defensive bonus for being in a base is factored in). Against other naval vessels,
ships in port fight as normal.

PSI COMBAT
Psi combat is conducted by the native life forms of Planet (mind worms, Isles
of the Deep, Locusts of Chiron) and by certain advanced technological units.
Psi combat seeks to turn the enemy’s own minds against them, inducing horrible hallucinations and phobias, which cripple the enemy’s ability to defend
itself, and may even induce self-destructive behavior.
Morale modifies the basic factors used for psi combat, such as weapon and
armor strength. Thus an Isle of the Deep of Mature Boil status (morale level 5)
would usually overrun a green unit (morale level 2), but would probably find
itself overmatched against a commando unit (morale level 6). Again, normal
weapon and defense strengths are completely irrelevant to psi combat—a tiny
Unity rover of Hardened status would be more likely to survive than a singularity cruiser of Disciplined status.

COLONIZING

PLANET

C H A P T E R

PSI COMBAT MODIFIERS
• The attacking unit gets a 3-to-2 advantage in psi combat when the defending unit is a land unit.
• Units may install the special abilities of Hypnotic Trance (discovered with
Secrets of the Human Brain) and Empath Song (discovered with Centauri
Empathy), which each provide +50% in psi combat.
• A faction’s units gain a +10% psi attack bonus for each positive level of
their Planet rating (see Social Factors, p. 141). Factions with negative Planet
ratings receive an equivalent penalty.
• The Neural Amplifier Secret Project gives its faction a +50% psi defense
bonus. The Dream Twister Secret Project grants a +50% psi attack bonus.

DAMAGE
When a unit takes damage, the colored bar graph located just above and
to the left shows how badly it’s been
hurt. As the bar descends, it also
changes color from green to yellow to
red. When the bar is completely
exhausted, the unit is destroyed.

Damage Bar

103

As surface units take damage, their movement rates decline. This reduces the
maximum move of vehicles with a move of more than one, and also makes it

Units repair damage by remaining undisturbed for a turn. To skip a unit’s turn,
press z. If they move or come under fire, they do not repair that turn.
No unit may repair itself to better than 20% damage (80% normal strength)
using field repairs, unless your faction possesses the Nano Factory Secret
Project. The Sentry command can streamline the field repair process, requiring
much less of your attention (L; see Action Menu, p. 92). In a base, several
facilities can repair an undisturbed unit in one turn:

• A Command Center repairs land units in one turn
• A Naval Yard repairs naval units in one turn
• An Aerospace Complex repairs air units in one turn
• A Biology Lab repairs native units in one turn
Units repair at least 10% of their damage each turn, modified as follows:
• +10% in friendly territory
• +10% if air unit at airbase
• +10% if land unit in bunker
• +10% if in a base
• x2 rate if a land unit is on board a Transport with a Repair Bay
• +100% if the controlling faction owns the Nano Factory Secret Project.

104

BASES AND FACILITIES
Numerous base facilities affect combat, either directly or indirectly.
All units inside a base get a +25% bonus to their defense, and units in bases
do not take collateral damage (see Damage, p. 103). You can designate a unit
to act as the primary defender (using cD, or the Designate Defender command in the Action menu), or the game automatically defends with the
strongest defensive unit in the base.
When the last base defender is eliminated in combat, the base population goes
down. This population loss can be avoided by building a Perimeter Defense
facility in the base.
Building a Perimeter Defense or Tachyon Field doubles the defense strengths
of all the units in the base. Building both of these facilities triples defense
strengths.
Units in a headquarters base automatically gain +1 Morale when defending.

PLANET

CONQUEST AND ANNIHILATION
When all the combat units defending a base are destroyed (including naval
units “in port” and air units “on the strip”) the base can be entered by an
attacking unit, causing the base to pass into the control of the attacking faction. (If a wild native life unit is attacking an undefended base, the native life
form devours one citizen from the base, then dissipates.)
If the base population is reduced to zero in combat, the base ceases to exist.
Any Secret Projects within it are lost forever, to all factions. Land units within
the base at the time of its destruction are left intact; sea and air units are
destroyed.
Conquering a base destroys a random number of the base’s facilities.

ATTACKING ENHANCEMENTS
You can destroy enhancements in an undefended square, including roads,
farms and other enhancements, by moving a unit onto that square and executing the Destroy Enhancement command (D).You can destroy only one
enhancement per unit per turn. In squares with multiple enhancements you
are prompted to choose the one to destroy.

105

AIR, COASTAL AND ARTILLERY BOMBARDMENTS
You can attack enhancements in undefended squares using artillery, aerial
bombing runs, or coastal bombardment. However, unlike a direct attack, such
actions are not guaranteed to be successful—they have a certain percentage
chance of actually hitting something significant. Air units attack enhancements with a 75% success rate, artillery attacks with a 50% success rate, and
missiles always hit their targets. If you are successful bombarding a square
using artillery, a random enhancement is destroyed. If you attack using aerial
bombardment, you choose the enhancement to destroy.
Artillery and naval bombardment attacks are made using Long Range Fire (see
Action Menu, p. 92). Air attacks are made by moving into the square and
using the D (Destroy Enhancement) command.

ATROCITIES
Atrocities are crimes against humanity. They always draw a radical response
from the other faction leaders, ranging from trade sanctions to a war of extermination against your faction. But, if a majority of the Planetary Council votes
to repeal the U.N. Charter (see Planetary Council, p. 132), then these actions
no longer count as atrocities.
Atrocities include:
• Planet Buster. Any use of the base-destroying planet buster missile. This
will cause swift and harsh reaction from all factions.
• Nerve Gas. Activating the nerve gas pods special ability in combat.
• Genetic Warfare. Probe teams (see Probe Teams, p. 133) can conduct
genetic warfare against a base’s population.

106

• Obliteration. Wiping out one of your own bases is considered an atrocity.
Wiping out a base you just conquered calls for a much more severe penalty than wiping out a base you built yourself.
• Nerve Stapling. This is one of the lesser atrocities, evoking less outrage
from the other factions since it is committed only against your own citizens.
However, if you commit this act against a conquered base, it is treated much
more seriously. You can nerve staple the entire population of a base, a
process that eliminates both drones and talents, making Drone riots (see
Drone Riots, p. 63) impossible for a length of 10 turns.

SPECIAL CASES
ALIEN ARTIFACTS
Alien artifacts have no defensive capability — except that they cannot be
destroyed in combat. Instead, when an enemy unit attacks a square with an
undefended alien artifact, or the artifact moves adjacent to an enemy, the artifact passes into the possession of the enemy faction. Likewise, when the last
defender of a base falls, any alien artifacts within the base emerge and pass
into the control of the attacking faction.
PROBE TEAM COMBAT
Probe teams cannot attack most units (outside of their probe abilities), but
they can attack other probe teams. Probe team combat, like psi combat, is
influenced by the Morale level of the two combatants (see Psi Combat, p. 102,
and Morale/Lifecycle, p. 87).

CONTROLLING SOCIETY
There’s far more to building a successful empire than building facilities and
pushing units around. Sid Meier’s Alpha Centauri allows you to manipulate
economic forces, diplomacy, espionage and political ideology to strengthen
your faction’s hold on Planet.

HQ MENU
The options on the HQ menu are your primary tools for both long-range planning and information about your faction’s progress.
SOCIAL ENGINEERING E
This screen is used both for Social Engineering proper (see Society Window,
p. 136), and for energy allocation (see Energy Allocation, p. 117).

SET RESEARCH PRIORITIES\CHANGE RESEARCH GOAL sR
This option allows you to switch from one research project to another in midstream. This can be useful if, for example, the Gaians begin work on the
Xenoempathy Dome (which you consider crucial to your long-term strategy),
and you still haven’t started research on Centauri Meditation, the prerequisite
technology to building this project.
This functions in two ways, depending on whether the “Blind Research” rule
was selected for your game. (See Game Rules, p. 197.) If “Blind Research” was
selected, then you are prompted to select a new area in which to concentrate
your research (see Technology, p. 119). If “Blind Research” was not selected,
then you may choose a new technology to research.
If you elect to change research goals with “Blind Research” off, you are
prompted to select a new goal. Note that if you switch research projects with
“Blind Research” off, you lose half of the research you put in to the previous
project (see Switching Production, p. 79). This means that it’s better to switch

ENERGY ALLOCATION

“Lock” Icon
Each of your bases requires a certain amount of energy to maintain. It is up
to you, however, to decide how to best allocate your energy surplus. There are
three priorities among which you must divide your energy resources: Labs,
Psych and Economy.
Adjusting Energy Allocation. You allocate your energy using the three sliding
bars on the bottom of the Social Engineering Screen (see HQ Menu, p. 110).
You can increase or decrease any of the bars in increments of 10% (of your
total energy budget) if you L on the arrow icons: left to decrease, right to
increase. When you get one of the values to where you want it, you can L on
the lock icon to lock it down, and thereafter all exchanges are between the
other two values. (Otherwise the game decides how to add or subtract energy
when you alter the levels.)

117

At the start of the game your energy allocation is set to 50% Labs, 50%
Economy and 0% Psych.
• Labs. Lab investments go directly to research. The more you invest, the
faster you discover new technologies, facilities and Secret Projects.
• Psych. This investment is spent on recreation, culture and basic luxuries.
The more you invest in Psych, the more workers become talents, offsetting
the malcontent drones in your bases (see Citizens, p. 61).
• Economy. Energy reserved for Economy goes to support your existing base
facilities, with any excess stored in your energy reserve. The more you invest
in Economy, the more wealth you have available for emergencies.

CONTROLLING

SOCIETY

C H A P T E R

Making radical adjustments in your allocation levels creates inefficiency. This
loss to inefficiency is displayed on the Social Engineering Screen (a high
Efficiency rating — see Social Factors, p. 141 — can diminish such losses). In
general, the greater the difference between your Labs and Economy settings,
the more inefficiency occurs.

INEFFICIENCY
As your faction expands to new bases, the bureaucracy required to administer
it grows more unwieldy. The net result of this inevitable process is inefficiency
— a certain amount of resources that a base collects are never available for
actual use. The efficiency of any given base is directly related to both its size
and its distance from your faction HQ. Larger, more remote bases are most
prone to inefficiency.

118

The primary way to combat inefficiency is through Social Engineering (see
Society Window, p. 136), but inefficiency can also be curtailed via certain
facilities, such as the Children’s Creche. Relocating your headquarters to a central location can also help control inefficiency.
You create a different kind of inefficiency when you adjust your energy allocations in extreme ways (see Energy Allocation, p. 117). This inefficiency reflects
the principle of diminishing returns—past a certain point, the more effort you
put towards a particular priority, the less the effect of the increased effort.

CONTROLLING

SOCIETY

C H A P T E R

TECHNOLOGY
The success of your faction on Planet is judged, to a great extent, on your
ability to acquire new technology.
Scientific breakthroughs are a large part of technology advances, but they’re
not the whole story. For example, any primitive tribesman of old Earth could
hollow out a tree and make a canoe, but your faction can’t build sea-going
units until it acquires Doctrine: Flexibility. This isn’t because water works differently on Planet, it’s because it takes a great deal of work, planning and
inspiration to set up a self-sustaining shipbuilding industry of the sort required
to produce high-tech, ocean-going vessels on command.
Many of these technologies combine a new scientific discovery with a new way
of looking at the world. The result is usually quite useful.

RESEARCH
Your faction can research only one technology at a time. When you acquire a
new tech, you begin research on your next discovery. Most technologies can
only be researched after certain other technologies—its “prerequisites”—have
already been discovered, so as you advance technologically, your options grow
and change. Your research efforts can be augmented by allocating more energy to Labs, building base laboratory facilities, and creating scientifically oriented specialists in your bases (see Appendix 2: Technology Tree, p. 185, for
a list of all technologies).

119

BLIND RESEARCH
Normally (unless you disable the option during game setup) your research is
“blind.” You do not select a specific research goal. Instead, you are asked to
choose a research priority, and your goal is randomly selected according to that
preference. You can select multiple priorities, which increases the number of
technologies available under your preferences.
If you disable blind research, you select specific technologies to work towards.

CONTROLLING

SOCIETY

C H A P T E R

5

However, the list of available technologies at any given time is random, and
does not necessarily include every technology for which you have completed
the prerequisites.

THE TECH TREE
Technology advances are like building a house—you have to start at the bottom
and work up. Technologies are not discovered in a vacuum; each new discovery
depends on everything that’s gone before it. In Sid Meier’s Alpha Centauri, the
underlying structure that determines the order of breakthroughs is called the Tech
Tree. When you first land on Planet there are a few initial technologies towards
which you may begin to direct your research. From this foundation you begin to
build the technological superstructure of human civilization on Planet.

120

The entire tech tree is displayed on the poster included with this game. You
can also view the tech tree in the game itself, using the Datalinks or the 2
hotkey. In the Datalinks, techs with white lettering are those you’ve already
discovered, techs with dark lettering remain to be discovered.
Prerequisites. With the exception of the first seven technologies, each new
technology requires that at least one and usually two other technologies be
acquired before it can even be researched. These precursor technologies are the
prerequisites of the new technology (which in turn is a prerequisite for one or
more technologies to come). Knowing the prerequisites for an important technology is an essential part of formulating an effective research strategy. For
example, if you want to be the first faction to learn Secrets of the Human
Brain (and obtain the bonus technology that distinction brings you), you must
know that you have to discover Social Psych and Biogenetics first.
Prerequisites for a given technology can be found in the Datalinks of the
game, and are shown on the Tech Tree poster.
Tracks and Levels. The technology tree is divided into four technology tracks.
These divisions have no direct game effect, but they do make it easier to keep
track of your progress up the tech tree. The four tracks are:
• Explore. Discoveries that make it easier to unravel the secrets of Planet.

CONTROLLING

SOCIETY

C H A P T E R

5

• Discover. Theoretical breakthroughs in the realm of “pure science.”
• Build. New technologies that enhance the infrastructure of your faction and
its bases.
• Conquer. Military advances.
The levels simply record how far along the track a given technology lies. For
example, Monopole Magnets, the discovery that makes the mag tube enhancement possible, is Build 6, expressed as B6. When trading techs with other factions, you can compare these numbers, to get an idea of which faction is getting the better deal.

ACQUIRING TECHNOLOGY
Your scientists in their research labs drive your technology acquisition. But
there are several other ways to pick up tech, and it’s in your best interest to
exploit as many of them as possible.
Research. As long as you have any energy allocated to Labs, your faction conducts research.

121

Unity Pods. Some of the pods left by the Unity contain downloads from the
Datalinks of old Earth which, when combined with your own discoveries, can
provide the key to unlock a new technology instantaneously.
Alien Artifacts. These esoteric devices can be taken to a base and linked with
that base’s network node (if it has one). Such a linkage inevitably provides an
instant tech advance. Normally, the network node for any given base can only
be linked to a single artifact (the Universal Translator Secret Project is the only
exception to this rule—you may link any number of artifacts to it).
Diplomacy. One of the most common forms of diplomacy, particularly early in
the game, is for the leader of another faction to offer to trade a technology you
need for a technology he or she needs. Sometimes he or she also offers to trade
technology for a copy of a world map, or even for energy credits. Sometimes,
the other faction just demands that you fork a tech over unilaterally. You can
initiate similar requests to the other leaders (see Diplomatic Contact, p. 127).

CONTROLLING

SOCIETY

C H A P T E R

Probe Teams. Probe teams can steal technology from other factions (see Probe
Teams p. 133).
“Secrets” Technologies. The three “secrets” technologies (Secrets of the
Human Brain, Secrets of Alpha Centauri, Secrets of Creation) each provide an
extra instant tech advance to the first faction to discover them.
Secret Projects. The Universal Translator gives the faction that builds it two
instant tech advances immediately after it’s built. The Planetary Datalinks give
you instant access to any technology that is already known to any three other
factions. The Network Backbone and Supercollider can greatly enhance your
tech output.
Conquest. In some games (depending on what rules options you selected; see
Game Rules, p. 195) conquering an enemy base allows you to select any one
of that faction’s technologies that you do not already possess.

122

THE USES OF TECHNOLOGY
The biggest reason to research new technology is that it lets you build new
things—units, facilities and Secret Projects. That’s not all it does, however.
Technology can also:
Increase your production. Certain discoveries lift caps on the maximum
amount of a given resource you can take from a given square. Other discoveries increase your ability to take resources from fungus squares. See Fungus
Production, p. 43.
Expand your infrastructure. Some later discoveries can make certain key base
facilities part of your infrastructure—they are added to every new base that’s
built, at the time of establishment (bases that were built before the discovery
have to build the facility normally). See Facilities, p. 64.
Grant access to specialists, enhancements and social options. New technologies can give you access to new specialists (making current technologies
obsolete), new terraforming enhancements, and new social options (see
Society Window, p. 136).

DIPLOMACY
The least predictable part of your own faction’s survival on Planet is dealing
with the other six factions. Each of the other faction leaders is a distinct personality, with his or her own goals, motivations and temperament. You have
to know when to get tough and when to ease off, when giving a little yields
long-term rewards and when it just makes you seem weak.

FACTIONS
Each faction behaves in a manner consistent with its individual nature.
The philosophies of the factions mentioned below are explained beginning on p. 11.
Distinguishing data for the factions is given in several categories:
• Faction Characteristics are adjustments to social factors that are intrinsic
to that faction.
• Aggression indicates how eager the faction is for a fight. There are three
levels: Aggressive, Erratic, Pacifist.

123

• Priorities represent what’s most important to the faction. There are four
possible priorities:
Explore (The faction seeks to occupy as much territory as possible)
Discover (The faction seeks to discover new technologies)
Build (The faction seeks to build up its bases as much as possible)
Conquer (The faction seeks to maximize military strength)
• Starting Tech is any technologies that the faction automatically possesses
at the start of the game.
• Agendas are Social Engineering choices that the faction always makes,
when available.
• Aversions are Social Engineering choices that the faction never makes.

DIPLOMATIC CONTACT
Before you can contact any of the other faction leaders, you must first have
their commlink frequencies. This is usually gained by coming into direct contact with one of that faction’s units, but can also be gained from a third faction, or sometimes even found in a Unity pod. The Empath Guild Secret
Project also grants you the comm frequency of every faction leader.
When one of your units or bases comes into contact with the unit or base
of another faction for the first time, you usually open communications with
the faction’s leader. If you talk to another leader once, you exchange comm
frequencies. Once frequencies are exchanged, the other leader might contact
you, or you can contact him or her using your Commlink menu (see
Commlink, p. 23). When another leader calls, you don’t have to answer, and
likewise he/she might sometimes ignore your communications (particularly
in hostile situations). Once communications are underway, there are many
options.

SOCIETY

Sometimes communications are terse—a curt demand that a unit be removed
from faction territory, or a to-the-point death threat—but many are quite
involved conversations. At any point during communication you can consult
the Datalinks for information about the faction, technology they may be
requesting, or military units.
When you are in communication with another faction leader, he or she might
start off by offering you an alliance against a common enemy, or offering to
improve your diplomatic relations status (see Diplomatic Relations, facing
page). They’ll often offer to trade technology or world maps, and they’ll frequently demand tribute of tech or energy (sometimes expressed as a “fine” for
some unspecified infraction of their faction legalities). They’ll often tell you
about their latest military innovation, to let you know they’re ready for trouble. They might even offer to end a vendetta between your factions. Once
these preliminaries are over, it’s your turn. Your options are:

128

OFFER A PROPOSAL
Proposals that may be offered include:
• A gift, or “token of your esteem,” consisting of technology (one or all of
your available technologies), energy credits, or even one of your bases. This
makes a leader more friendly towards you, and if the gift is truly significant,
she might forgive your past transgressions.
• Upgrading diplomatic relations (truce to treaty, or treaty to pact brotherhood).
If your first proposal is accepted, you can try to upgrade again immediately.
• A request for technology, either as extortion or in trade.
• A request for energy credits, as extortion, in trade, or as a loan.
• A joint attack against a common enemy.
EXCHANGE BATTLE PLANS
You and the other faction leader discuss your immediate plans for battle, in
order to coordinate your efforts. The other leader presents you with a list of
targets, and you may select the target that you wish the other leader to attack.

SOCIETY

CALL OFF VENDETTA
You request the other faction leader call off his or her vendetta against a
third faction.
REQUEST VOTE
You request that the other faction leader support you in an upcoming council session. Often such support comes at a steep price.
TERRITORY VIOLATION
You demand that the other leader immediately remove all his or her units from
your territory.

DIPLOMATIC RELATIONS
Your relations with any other faction at any given moment depend on a number of factors, including your social choices, your proximity to their territory,
your military power, and of course your reputation and behavior during prior
diplomatic communications. When a faction leader is in communication, you
are given a one-word summary of that faction’s attitude towards you and of
their reported military preparedness.

*This is a special case of Magnanimous, encountered when the faction is hopelessly overmatched.
Mood is based on several factors, including how honest you’ve been with that
faction in the past, whether you’ve ever committed an atrocity against the faction, and how powerful you are in relation to that faction—faction leaders get
touchy and defensive when someone else is far stronger than they are. Small
factions often ally together to oppose very strong factions, even if the stronger
faction has behaved honorably.
Once you are in communication with a faction, your relationship settles into
one of four categories:
VENDETTA
A state of war exists. Each faction is under no obligation whatsoever to respect
the other’s territory, and you can attack one another’s units and bases with
impunity. Any loan payments are suspended.

130
TRUCE
A state of “watchful peace.” While the truce is in effect, the other faction may
not honorably attack your units, but may move his units into your territory
(you may attempt to threaten or cajole him into withdrawing). Loan payments
are made on schedule.
TREATY
A state of peace and cooperation. Both factions are expected to keep military
units out of the other’s territory (or at least remove them promptly when
asked). The bases of two factions with a treaty conduct commerce with one
another (see Commerce, facing page).
PACT OF BROTHERHOOD
A full diplomatic alliance. Both sides share their world maps, can access the
other’s report readouts (see HQ Menu, p. 110), and may move freely through
one another’s territory (zones of control do not apply between pact brothers).

CONTROLLING

SOCIETY

C H A P T E R

Units from one faction may even visit the other’s bases for repairs and leave
units in the same square. Income from commerce is increased. If one pact
brother declares vendetta against a third faction, the pact partner is expected
to do the same.

COMMERCE
If you have a treaty or pact with another faction, the two factions’ bases automatically conduct trade with one another. The amount of commerce income
depends on your respective social choices and the size of the bases involved.
Pact Brotherhood results in more profitable commerce than a simple treaty—
commerce rates are doubled.
The largest bases in the two factions trade with one another, as do the two
next largest, and so on until one side or the other runs out of bases.

TERRITORY
Any squares which are nearer to one of your bases than to any other faction’s
base are considered your territory. Territory cannot extend more than seven
squares out from a land base, or three squares out from sea bases, and must
be on the same continent (or sea) as the base claiming it. Building a base close
to another faction’s territory may cause boundaries to be re-drawn. It is entirely possible for bases from rival factions to be so close that the territorial
boundary runs through both bases’ production radii.

131

INTEGRITY
As you interact with the other factions, you inevitably gain a reputation. This
is based less on your belligerence than upon your honesty. You can attack literally everyone you see, but if you don’t break any treaties or commit any
atrocities while doing so your honor remains unbesmirched.
The levels of integrity are:
Noble

Scrupulous

Ruthless

Faithful

Dependable

Treacherous

CONTROLLING

SOCIETY

C H A P T E R

You can wreck your good name by breaking treaties and committing atrocities. If your integrity is towards the “treacherous” end of the scale, other factions are less likely to make deals with you, and more likely to break any
treaties that do exist.

PLANETARY COUNCIL
The final tool of diplomacy on Planet is the Planetary Council. You can convene
this body at any time, once you have the comm frequencies of all the factions.
No leader can call the council more than once every 20 years (except the planetary governor, who can call the council every ten years), and at each meeting
it can consider only one proposal. (Electing a leader does not count against
this limit, however.) No single proposal can be considered more than once
every 20 years.

132

The first order of business for the council is probably electing a Planetary
Governor. This post mostly consists of chairing council meetings, but the
Governor does gain an increase to trade and better intelligence against the
other factions. The most direct power of the Planetary Governor is the power
of veto over any council actions—the governor’s veto can only be overridden
if all of the other leaders unite against it. In the vote for Planetary Governor,
it is entirely acceptable to cast your vote for yourself. When an election is
called, you see whom each faction is publicly supporting for the election, but
this may not be who they actually vote for.
In votes for Planetary Governor (and later, in votes for Supreme Leader), each
faction is given a variable number of votes in council depending on its population. The voice of a larger, richer faction counts for far more than the voice
of the small and weak. Only the leaders with the two largest vote totals are
eligible to stand for Planetary Governor or Supreme Leader.
Other council actions are decided by simple majority vote (subject to veto by the
Planetary Governor). Matters that may be brought before the council include:

SOCIETY

• Salvage Unity Fusion Core. The rare elements from the Unity’s core provide 500 energy credits to each faction.
• Global Trade Pact. Increases income from inter-faction commerce.
• Launch Solar Shade. Causes temperatures to drop world wide, making sea
levels go down.
• Melt Polar Caps. Causes global warming, making sea levels go up.
• Repeal UN Charter. All atrocity prohibitions are removed.
• Reinstate UN Charter. If the council chooses to repeal the charter, it can
later vote to reinstate it.
Not all of these options are necessarily available at any given council meeting.
Many of the more radical terraforming operations have prerequisite technologies that must be discovered before they can be proposed.
In your regular communications with other council members you may request
that they vote your way in council. You can even offer them “special considerations” (bribes) in exchange for their votes.

133

PROBE TEAMS
Somewhere between war and diplomacy is the realm of the spy. Probe Teams
combine espionage and electronic warfare, plus a fair dose of terrorism in their
capabilities. An effectively coordinated program of Probe Team operations can,
all by itself, give your faction a decisive advantage in the ongoing contest for
supremacy.
Probe teams cannot attack other units directly, but they can battle one another to the death. Probe Team combat is based on the morale of the combatants. Probe Teams can attack other teams even in squares containing other
units. Since Probe Teams have no “official” existence, destroying another faction’s Probe Teams does not violate a treaty or pact.

SOCIETY

PROBE TEAM ACTIONS
Probe Teams are covert ops agents. They infiltrate the bases and territory of
other factions and conduct espionage and sabotage.
Some Probe Team actions require an investment of energy. How much depends
on the severity of the action and the enemy’s strength. Most major Probe Team
actions are legitimate grounds for Vendetta and, in the event you are caught, may
cause your reputation among the other factions to suffer (See Integrity, p. 131.)
When you initiate any Probe Team action, you are shown your chance of success, expressed as a pair of percentages (the higher your Probe Team’s morale,
the better the odds). The first percentage shown is the team’s chance of completing the operation, the second is its chance of escaping alive. When a Probe
Team enters a base or any square containing an enemy unit, it may attempt
the following actions:

134

INFILTRATE DATALINKS
The probe team hacks into the faction’s Datalinks. This greatly increases your
intelligence data about that faction, including access to their report readouts,
and even individual base readouts.
STEAL TECHNOLOGY
Just what it says. You grab the other faction’s research technology. You may
try for a specific technology, or grab one at random. Attempts to steal specific technology are much more difficult.
SABOTAGE BASE
You can either destroy an existing facility, wreck Planet Buster silos, or wipe out
all minerals accrued towards that base’s current build orders. You may target a
specific facility, or destroy something at random. Attempts to sabotage a specific facility are much more difficult. You cannot sabotage faction HQ or Secret
Projects. Perimeter Defenses and Tachyon Fields are extremely hard to target.

MIND CONTROL
Mind control is an attempt to subvert a base or unit of a rival faction and
bring it under your control.
The attractive aspect to unit mind control is that it’s one of the few probe activities that don’t need to be carried out from inside an enemy base—your Probe
Team can lurk in the wilderness or near your territorial borders and swoop
down to grab any unit that gets too close. Only single units may be targeted
by Probe Teams. Multiple units in a square are invulnerable to mind control.
The Total Thought Control option is a variant of mind control that takes control of a base or unit, without causing any damage to your reputation with the
other factions. It costs the same as normal mind control, but has a lower
chance of success.
The cost of a mind control operation against a base depends on a number of
factors, including the base’s size, the enemy’s energy reserves, facilities and
special operations in a base, and whether or not drone riots are occurring.

135

A Probe Team cannot take control of a base containing a faction’s headquarters.
INCREASE DRONE ACTIVITY
This operation changes one Worker or Talent in the enemy base into a Drone.
This is a useful preliminary operation to a mind control attempt, since a base
embroiled in drone riots is significantly easier and less expensive to mind control.
DRAIN ENERGY RESERVES
This ambitious operation attempts to divert a portion of the faction’s energy
reserves to your accounts. The more reserves the faction has, the more you
stand to gain.
GENETIC WARFARE
This is considered a severe atrocity. A successful genetic warfare operation
decreases the population of the base by a full 50%, instantaneously. Units
inside the base also lose strength to the virus.

DEFENDING VS. PROBE TEAMS
Other than physically hunting them down and destroying them, your best
defense against enemy Probe Teams is to boost your Probe rating through
Social Engineering (see Society Window, below). Investing energy towards
Psych also tends to deter Probe activities (see Energy Allocation, p. 117).
An excellent deterrent to enemy Probe Team activity is simply to station one of your
own Probe Teams in strategically important bases. An enemy Probe Team must
engage and destroy your team before it can undertake any further operations.
The Hunter-Seeker Algorithm Secret Project makes your entire faction immune
to probe activity.

SOCIAL ENGINEERING
136

Your faction has a purpose, a reason for existing, and that purpose is more
than just dominating all the other factions. Social engineering is the way you
put your social and political philosophy into action. Every Social Engineering
choice you make carries both benefits and liabilities for your faction. It is your
job to see that the benefits support your long-term strategy, and the liabilities
do not significantly detract from it.
Social engineering represents the fundamental defining characteristics of your
faction’s society. The choices you make in regard to these fundamentals literally affect every aspect of your faction. Use E or select Social Engineering
from your HQ menu to access the Social Engineering Readout.

SOCIETY WINDOW
The Society Window is the upper portion of your Social Engineering Readout
(the bottom portion, dealing with Energy Allocation, is described under
Energy Allocation, p. 117). This is where you actually pick the underpinnings
of your society. It consists of four lines, each representing a fundamental decision, and four choices for each line. You may make one choice from each line.
These choices determine your society’s base rating in each of the social factor

created a dangerous deficit in some other category.

Upheaval Costs. When you try to make a radical shift in political philosophy,
there’s going to be some social upheaval. To get your faction “over the hump”

SOCIAL FACTORS
Your faction possesses a numerical ranking (negative, positive or zero) in each
of the following categories. Positive ratings represent assets of your society,
negative ratings are liabilities. The specific results of each ranking in each factor are found in the table in Appendix 2: Social Factors, p. 158.
Although they’re most directly determined by your social choices (see Society
Window, p. 136), these ratings are also directly affected by your original faction philosophy, and several Secret Projects. Several base facilities can change
the ratings for that base only. Children’s Creche, for example, increases the
Growth rating for each base that builds one.
ECONOMY
Increases or decreases energy production by squares and by base; also
increases or decreases commerce income (see Commerce, p. 131).

141

EFFICIENCY
Increases or decreases loss due to inefficiency or modification of
energy allocation (see Energy Allocation, p. 117).
SUPPORT
Increases or decreases the cost to support units outside of your base.
High ratings can give you a number of units that can be supported
“for free” (see Home Base, Support and Pacifism, p. 89).

Negative scores increase ecological damage. Positive scores decrease damage,

RESIGNING
You may retire as faction leader at any time by selecting “Resign” from the
Game menu. This ends the game and computes your Sid Meier’s Alpha
Centauri score.
You must also resign if you reach the mandatory retirement year for your game
or scenario. In standard games, the mandatory retirement year is M.Y. 2500 for
Citizen, Specialist and Talent difficulty levels, and M.Y. 2400 for Librarian,
Thinker and Transcend levels.
You will be warned 20 years before you reach mandatory retirement.

WINNING THE GAME
There are four ways to win Sid Meier’s Alpha Centauri—conquest, diplomatic, economic or transcendence—depending on how you set your options in the
setup screens.

143

If you are playing a scenario, it may have specific and unique victory conditions different from those listed.

CONQUEST
You may win the game by conquest if you eliminate all remaining factions.
Factions that surrender and “swear a pact to serve you” count as eliminated
for this purpose. If Cooperative Victory is enabled, you need not eliminate any
faction with whom you have signed a Pact of Brotherhood, though no more
than three non-surrendered factions may ‘win together’ in this manner.

DIPLOMATIC
You may win the game diplomatically by convincing enough faction leaders to
unite behind you as Supreme Leader of Planet. A 3/4 vote of the Planetary
Council is required to secure such election. Only the leader of one of the two
factions with the highest vote totals may stand for election as Supreme Leader.

CONTROLLING

SOCIETY

C H A P T E R

5

When a Supreme Leader is elected, a faction leader may choose to defy the will
of the Council and refuse to submit. In this case, the Supreme Leader must,
with the help of loyal factions, conquer all defiant factions to achieve a
Conquest victory. Because of the military power usually required to secure election as Supreme Leader, defying the will of the Council is generally fairly suicidal. Other factions will therefore usually take this course only if you have committed atrocities against them or have grossly and repeatedly betrayed them.
You must have the Mind\Machine Interface technology before you can try for
a Diplomatic Victory.

ECONOMIC
You may win an Economic Victory by cornering the Global Energy Market. You
must have discovered Planetary Economics in order to pursue such a plan.

144

Cornering the Global Energy Market requires a sum of energy credits roughly equal
to the cost to “mind control” every remaining base on Planet. When you are ready
to make such an attempt, select Corner Global Energy Market from the HQ menu.
When a faction attempts to corner the Global Energy Market, all other factions are given an allotted period of time in which they can capture or destroy
the cornering faction’s headquarters and thereby foil the plan.

TRANSCENDENCE
The highest form of victory is the Ascent to Transcendence, the next step in
the evolution of humanity. In order to ascend, you must complete an extraordinary Secret Project—the Ascent to Transcendence—which can be started only
after at least one faction has completed the Voice of Planet Secret Project.

SCORING
Whether you resign or win outright, each game is given a numerical score. You
can check your current score at any time with 8, or the Alpha Centauri

Your Alpha Centauri Score is computed as follows:
• 1 point for each citizen of each base.
• If you have won a Diplomatic or Economic victory, score 1 point for each
citizen of a Pact Brother’s base.
• 1/2 point for each citizen of any other faction’s base.
• 1/2 point for each citizen of a surrendered base.
• 1 point for each unit of commerce your bases are receiving.
• 1 point for each technology discovered.
• 10 points for each tech advance after Transcendent Thought.

145

• 25 points for each Secret Project.
• A Victory bonus if you have won the game (see Winning the Game, p. 143):
For winning by Conquest, you are awarded 1000 points minus 2 for every
game turn elapsed. If Cooperative Victory is enabled, all Pact Brothers and
Sisters participate in the win, and points are split between all winning factions based on relative population. A maximum of three Pact Brothers and
Sisters may join in a win by conquest, not including those factions that have
surrendered along the way.
If you win a Diplomatic Victory, you are awarded 1200 points minus 2 for
every game turn elapsed. If Cooperative Victory is enabled and your Pact
Brother or Sister is elected Supreme Leader, you are awarded half this total.
For Economic Victory, you are awarded 1200 points minus 2 for every game
turn elapsed. If Cooperative Victory is enabled, Pact Brothers and Sisters of
the winning faction receive half the bonus points.

NOTES AND TIPS
GENERAL TIPS
• Pick your faction wisely. The bonuses and penalties intrinsic to each faction
may seem minor, but they exert a constant influence on the faction’s development throughout the entire game. Therefore, you want to select a faction where the abilities are an asset to your personal style and long-term
strategy, rather than a detriment.
• Don’t be afraid to use the governors and automate units. This can make
gameplay flow much more smoothly, without reducing your actual control
over your units and bases in any significant fashion.

148

• Watch how you place your bases. Try to use all the resources from as many
squares as possible. Don’t place bases directly within one another’s production radius, but it’s okay to let the radii overlap a bit. Try not to let any
potentially productive squares go to waste.
• Build several colony pods early in the game, to give your faction some territory as quickly as possible. From a strategic perspective, it’s never a good
idea to have all your eggs in one basket. Plus, more bases gives you bigger
energy reserves, faster tech research, and increased capacity to produce
Secret Projects and offensive units.
• When you start a base, build a defensive unit right away (more than one, at
higher levels of play). Also build at least one former per base.
• Make sure to build several bases on the coast. This allows your faction to
produce sea-based units.
• Never forget that units can hide in fungus.
• Explore as much as you can early on, while rival factions are small and relatively friendly and mind worms are young and wimpy.

TIPS

• Don’t mess with your economy settings until drones actually start to
become a problem in your bases (and even then, see if you can take care of
the problem with social choices or simple facilities first).
• A good basic strategy for building base facilities is simply to build the cheapest ones first. However, you might want to concentrate on network node (particularly if you have an artifact, or expect to build the Virtual World Secret
Project) and hab complex (if your population is growing quickly). Do not build
pressure domes or punishment spheres unless you know exactly what they’re
for and are certain they’re what you want (see Appendix 2: Facilities, p.
163)—these facilities are useful only in specialized circumstances, and the
punishment sphere can actually hold you back in specific ways.
• The more Secret Projects you can hog for yourself, the better. Even the ones
you don’t plan to use are useful, because you’re keeping them away from
some other faction.
• The earliest Secret Projects are among the most useful, particularly the
Human Genome Project and the Virtual World, both of which can give your
faction a power edge in stability.
• Plant forests to make arid squares productive. Plant some early to give them
time to grow.
• If a rival wants to trade technology, trade technology. Every tech advance
helps your faction, and an even trade is a good deal—it puts you that much
ahead of the other factions not involved in the trade.
• If your faction achieves clear dominance over the other factions, call an
election and make yourself Planetary Governor. It’s worth it for the trade
windfall alone.
• Secrets of the Human Brain can give you an important tech edge in the
early part of the game. Unfortunately (for the other factions), the
University and the Peacekeepers are about the only factions with a realistic shot at it. All other factions require some major luck to get this tech
first (though it can happen).

Energy

In order to harvest energy based on a square’s elevation, the square must have a solar collector. Squares
with solar collectors yield 1 energy for each thousand meters above sea level, starting at 1 for squares 0
to 1,000 meters above sea level, up to 4 for squares over 3,000 meters above sea level.

Rocky terrain negates all nutrient production from raininess.

• Move Cursor to Here. Moves the cursor to the square on which you :.
• Move Unit to Here. Moves the active unit to the square on which you :.
• Center on Active Units. Centers the map on your active unit. Can be used
if you’ve lost track of where the next unit to move is.
• Activate Units Here. Activates the units on the square on which you :.
• End the Turn. Cancels any further actions and ends the turn.

• Info On This Square. Displays information about the square in the Data
View (see p. XX).
• Help. Displays Help Menu (see p. 31).
In addition, the : menu may display additional options depending on the
contents of the square.
If there is a base in the square, the options include:
• Zoom To Base. Opens the Base Window (see p. XX).
• Change Production. Opens the Production Readout for the base (see p. 78).
• Hurry <current project>. Where <current project> is the name of the
project currently underway. See Build Orders, p. 67.
• Set To Explore.
• Set to Discover.
• Set to Build.

(These four are options for the base governor. See Governor, p. XX.)
If the active unit is in the square, the options include:
• Action. Opens the Action Menu (see p. 46).
If the active unit is a terraformer and is in the square, the actions include:
• Terraform. Opens the Terraform Menu (see p. 46).

GAME RULES
• Higher Goal: Allow Victory by Transcendence
• Total War: Allow Victory by Conquest
• Peace in Our Time: Allow Diplomatic Victory
• Mine, All Mine: Allow Economic Victory
• One For All: Allow Cooperative Victory. Your pact brothers can help you
achieve victory conditions, and share the victory with you.
• Do Or Die: Don’t Restart Eliminated Players. Normally, if a faction is eliminated (particularly early in the game), the leadership escapes and founds a
new base elsewhere on Planet. Under this option, when a faction’s gone, it’s
gone for good.
• Look First: Flexible Starting Locations. When you make planetfall, your
colony pod waits for you to order it to build your first base, allowing you
to reposition the base if you wish.
• Tech Stagnation: Slower Rate of Research Discoveries. Technological
progress is slowed down across the board.
• Spoils of War: Steal Tech When Conquer Base. When you conquer a base
of a faction that possesses technology that your faction does not, you may
select one technology to steal.

O P T I O N

S C R E E N S

197

A P P E N D I X

3

• Blind Research: Cannot Set Precise Research Goals. You select broad categories for your researchers to concentrate their efforts, based on the priorities you set between Explore, Discover, Build and Conquer.
• Intense Rivalry: Opponents More Aggressive. The other factions are much
more willing to fight (and more likely to gang up on you).
• No Unity Survey: World Map Not Visible. You know nothing of the world
other than squares you have actually explored and their immediate vicinity.
• No Unity Scattering: Supply Pods Only at Landing Sites. There are some
Unity pods near your first base, but nowhere else.
• Bell Curve: No Random Events. Most random events are disabled.
• Time Warp: Accelerated Start. You start the game some years after planetfall, with several bases, technologies and enhancements.

198

• Iron Man: Save/Restore Restricted To Exit. Autosaves are disabled except
when you actually leave the game—no going back to undo mistakes.
• Randomize Faction Leader Personalities. Leaders behave in unpredictable
ways.
• Randomize Faction Leader Social Agendas. Faction leaders do not adhere
to preset social agendas.

GAME PREFERENCES
PREFERENCES
• Tutorial Messages. The game displays “pop-up” hints and suggestions.
• Design Units Automatically. The game gives you pre-designed units at
each appropriate technological advance.
• Auto-Prune Obsolete Units. Automatically deletes obsolete, out-of-production units from your production readout. It is recommended that you

O P T I O N

S C R E E N S

A P P E N D I X

3

leave this option on, as your production readout has a finite number of slots
for units, and these can fill up very rapidly with obsolete units.
• Mouse at Edge Scrolls View. Moving your mouse to the edge of the screen
(not the edge of the map) causes the map to scroll in that direction.
• Autosave Each Turn. The game creates a new autosave file at the end of
each turn. These files are kept in the AUTO subdirectory of your SAVES directory. To load an autosave, L on AUTO when the load window opens and
select the turn you wish to return to. Autosaves are kept for turns 1-10, 20
and 30 prior to the current turn.
• Pause at End of Turn. When your turn is completed, the game pauses until
you L on the TURN COMPLETE button.
• Move Enemy/Neutral Pieces Quickly. Visible units from enemy or neutral
factions move quickly, without full animation.
• Move Allied Pieces Quickly. Visible units from allied factions move quickly, without full animation.

WARNING PREFERENCES
This menu is a list of actions or events that can occur at your bases. You may
select whether you wish the game to stop when one of these actions or events
occurs. If you choose to be warned about a given situation, you are shown a
window asking if you wish to zoom to the base where the situation occurred,
or ignore it and proceed with your turn. Even if you have these pop-up warnings off, you still get an automated message about the event in your message
window (see Data MFD, p. 26).
• Stop for New Facilities Built
• Stop for Non-Combat Units Built
• Stop for Combat Units Built

ADVANCED PREFERENCES
• Radio Buttons Select with Single Click. A single L both selects and confirms a button function.
• Click on Unit Always Cancels Orders. L on a unit to cancel any current
orders.
• Confirm Odds Before Attacking. The game displays combat odds whenever you make an attack move, then waits for you to confirm the attack. This
allows you to precisely gauge your odds of winning a combat.
• Pause Whenever Our Forces are Attacked. Play stops after you are
attacked, so you may analyze combat results.
• Fast Battle Resolution. Combat animations are speeded up, so the game
moves faster..

O P T I O N

S C R E E N S

• Move Units With Orders Quickly. Units carrying out preset movement
orders are not animated when moving into each square on their route. They
quickly “jump” from square to square.
• Move All Units Quickly. Units are not shown moving between squares—they
just appear in their next position.
• Don’t Center On Units With Orders. The game does not recenter on units
carrying out multi-turn orders.
• Zoom-To-Base Doesn’t Recenter Map. Allows you to open a base screen
when an event occurs, without centering your map on that base.
• Detailed Main Menus. Toggles between long, detailed menus, and shorter
ones with fewer options.
• Detailed Right-Click Menus. Toggles between a long, detailed : menu,
and a shorter one with fewer options.
• Right-Click Pops Up Menus. Allows you to toggle the : menu on or off.
When this option is off, if you :, the cursor moves to the indicated location. You can still get to the : menu by using s:.

AUTOMATION PREFERENCES
• Air Units Can Return Home When Reach Limit of Fuel Range. Air units
who exhaust their outbound movement automatically return to the nearest
base on the next turn. This keeps you from forgetting about an air unit with
low fuel.
• Automated Formers Can Plant Forests. Formers on “Auto” (see Terraform
Menu, p. 46) may plant forests.
• Automated Formers Can Raise/Lower Terrain. Formers on “Auto” (see
Terraform Menu, p. 46) may raise or lower terrain.
• Automated Formers Can Build Condensers, Boreholes, etc. . Formers on
“Auto” (see Terraform Menu, p. 46) may build these enhancements.

• Automated Formers Can Remove Fungus. Formers on “Auto” (see
Terraform Menu, p. 46) may remove fungus.
• Automated Formers Can Build Sensors. Formers on “Auto” (see Terraform
Menu, p. 46) may build sensors.
• Cancel Movement Orders When Spot Units w/ Pact. Any movement orders
are canceled when your unit sees a unit from a faction that is a pact brother.
• Cancel Movement Orders When Spot Units w/ Treaty. Any movement
orders are canceled when your unit sees a unit from a faction with which
you have a treaty.
• Cancel Movement Orders When Spot Units w/ Truce. Any movement
orders are canceled when your unit sees a unit from a faction with which
you have a truce.

202

• Cancel Movement Orders When Spot Units w/ Vendetta. Any movement
orders are canceled when your unit sees a unit from a faction against which
you have a vendetta.
• Do Not Cancel for Units of Different Class (land/sea/air). The above cancel options do not apply if your unit is a land unit and the other is a sea or
air unit, and so forth.
• Wake Passengers When Transport Reaches Land. If a transport moves
adjacent to a land square, the units inside automatically activate for orders.
• Always Investigate Monolith. A combat unit investigates a monolith any
time it visits a monolith square, without requesting your permission.

AUDIO/VISUAL PREFERENCES
• Background Music. Toggles background music.
• Sound Effects. Toggles sound effects.
• Voiceovers (Tech and Facility). Toggles the voiceover quotes that occur
when you discover a new technology or build a facility for the first time.

ADVANCED CUSTOMIZATION
Alpha Centauri includes a full range of editor functions that allow you to create your own maps or scenarios, alter the basic rules of the game, or just plain
cheat yourself silly (in single-player games only, of course). The designers
encourage players to become designers themselves, and see what new and
unexpected challenges their imaginations can create.

SCENARIO AND EDIT MAP MENU OPTIONS

206

The Scenario and Edit Map menus provide a number of powerful editing tools.
They are not considered part of the game itself, and using them cancels the
score of any game you are playing, but are provided for your enjoyment. Using
these tools, you can create your own scenarios, with custom maps, rules,
objectives and situations. Feel free to play around and create new scenarios for
your own use and that of your friends. We don’t have the space to document
all the features in the scenario and map editors, but here’s a few basics to get
you started:
• Activate Scenario Editor cK. When you want to edit a particular scenario or map, you must first activate the scenario editor from the Scenario
menu. Once you’ve activated the scenario editor, any game underway no
longer keeps track of the score.
• Edit Map options. The map editor allows you to build or tweak any map
using the options provided. Most are self-explanatory. When placing features, whether terrain or enhancements, remember that first you toggle a
particular feature, and then sL to place that feature, and s: to
remove that feature. All Edit Map features are displayed as icon toggles in
the central information window when the scenario editor is active.
• Save early, save often. The map and scenario editors can cause some program malfunctions because of the nature of these alterations. We suggest
you save your work early and often. Have fun!

EDITING TEXT FILES
Many basic rules of Alpha Centauri are set out in plain text files, which you
can modify with any text editor. (These files also let you customize the messages and quotes in the game, to humorous or dramatic effect.) You can, for
example, eliminate the extra cost for prototypes (or hike it to 200%), or add
an attack bonus for non-artillery units attacking the enemy from a higher elevation, or completely re-arrange the starting abilities of a faction.
Important rules files are alpha.txt, and the files for the individual factions;
believe.txt, gaians.txt, hive.txt, morgan.txt, peace.text, spartans.txt and
univ.txt. All the diplomatic language in the game can be found in script.txt.
These can all be found in the game’s root directly on your hard drive.
There’s not room to describe all the available options here, but the designers have
done their best to make it reasonably easy to modify these files, even for non-programmers. Many sections have an entry that describes the function of that section.
If you feel the urge to tinker, have fun. However, a few rules of caution are in
order before you start tweaking the game rules:

207

• Plain text only. Never, ever, ever save in any other format but plain text.
Otherwise formatting characters get in which screw things up. You might
not even want to open the file in anything other than a plain text editor, to
minimize the chances of unwanted formatting.
• The changes you make do change the game. Don’t be surprised if a relatively minor alteration turns out to have a major effect on game balance.
• YOU TWEAK AT YOUR OWN RISK. If you somehow manage to break the
game through file tweaking, you should uninstall the game and delete any
remnant files. Our Tech Support department cannot help you if you have
deliberately tweaked the game.
• Save everything. Before you start messing with the rules files, put the original files, plus any saved games you want to keep (look for files with the .sav
suffix) in a separate directory.

ADVANCED CUSTOMIZATION

A P P E N D I X

• Total meltdown. If you mess around with these files severely enough, the possibility exists that you might break the whole system—computers are surprising
that way. So once again, if you start playing around with rules files, it’s AT YOUR
OWN RISK. FIRAXIS Games and Electronic Arts™ will not be held responsible.
Note. You can create custom text files for use with custom scenarios. Create a
directory where you will store your scenario, then place the desired custom text
files in the same directory. When you launch the game and load a scenario,
the game looks for the text files from the same directory as the scenario first.
If it doesn’t find them, it looks in the root game directory as normal.

A NEW SUN
As the nearest stellar neighbor of the Sol system, there is a great deal more
data that can be collected about Alpha Centauri than can be amassed about
more remote stars. So far everything we know about Alpha Centauri suggests
that an earthlike world, capable of (at least potentially) supporting human life,
is entirely possible — and perhaps likely.

THE CENTAUR
The earliest astronomers identified groups of stars that seemed to fit together, into constellations (“stars together”). The most familiar of these include the
twelve constellations of the zodiac — the constellations through which the Sun
“passes” as the Earth completes its yearly revolution.

210

About A.D. 135, the Greek astronomer Ptolemy, working in Alexandria, Egypt,
catalogued the twelve zodiacal constellations, plus 36 more. One, just barely
visible on the southern horizon, he listed as Centaurus, the Centaur. Alexandria,
at 31.1° N, is further south than all of Europe and most of North America
(everything but parts of Texas and Florida, and most of Mexico) — no one north
of that point can see the Centaur. In fact, the two brightest stars of this constellation are too far south for even Ptolemy to have seen in Alexandria.
Since none of the well-connected astronomers of ancient times even knew
about these two stars, they never got the individual names that now identify
other bright stars (such as Polaris and Sirius). By the mid-1700s, 40 more constellations had been added to the 48 that Ptolemy had originally catalogued,
and these 88 spanned the heavens. In 1603, Johann Bayer published a catalogue, not just of constellations, but of all the brightest stars. The most visible star in each constellation became “Alpha,” the second-brightest “Beta,”
and so forth. The brightest star in the Centaur became Alpha Centauri. Alpha
Centauri is at the Centaur’s hip.

Brief Mythological Sidetrip. Other lands also have myths of half-horse, halfhuman creatures and races, but Centaurs are best known for their role in Greek
mythology. They have the body and legs of a horse, with the torso, arms and
head of a human. In some myths they are lustful and aggressive; in other tales
they are wise and reserved.

BRIGHT STARS
It’s obvious to anyone who sees it that Alpha Centauri is bright, but how bright
is it? About 130 B.C., Hipparchus divided the visible stars into “magnitudes.” He
recorded six levels of magnitude, later more precise measurements have determined that each magnitude is about 2.5 times brighter than the next magnitude. He listed 18 first-magnitude stars; four more were added to his list by later
astronomers, stars that were too far south for him to see. These four stars are
Alpha and Beta Crucis (in the Southern Cross) and Alpha and Beta Centauri.
In fact, Alpha Centauri is the third-brightest star in the sky, behind Sirius
(magnitude -1.42) and Canopus (-0.72), with a magnitude of -0.27. It’s over
three times brighter than the average first-magnitude star. (For the record, it’s
the tenth-brightest object in the sky, behind the Sun, the Moon, Venus, Mars,
Jupiter, Sirius, Mercury, Canopus and Saturn.)
But why is it so bright? The answer seems obvious today, but let’s briefly follow the trail of discovery that astronomers followed.

PROPER MOTION
In the early 1700s, Edmund Halley discovered that a few stars (Sirius, Procyon
and Arcturus) actually shifted position in the sky. In particular, bright stars
seemed to be more likely to move. That made it likelier that bright stars are
bright because they are closer to us. (It had already been decided that stars,
unlike planets, were too far away to reflect the light of the Sun, because they
didn’t seem any larger when viewed under magnification. The resulting theory was that stars generated their own light.)

A

NEW

SUN

211

A P P E N D I X

The motion that Halley discovered is called proper motion, because it is
motion of the star itself, rather than movement of the Earth. Halley couldn’t
see Alpha Centauri, but other astronomers soon discovered that it, too, has
proper motion. In fact, its motion is greater than that of any other bright star.
On the other hand, it’s not surprising this motion wasn’t detected by earlier
astronomers — it takes more than 500 years for Alpha Centauri to transit an
arc of space as wide as the moon.
However, the proper motions of several very dim stars — including 61 Cygni
(fifth magnitude) and Barnard’s Star (ninth magnitude) — are greater even than
that of Alpha Centauri. Barnard’s Star is almost three times as fast as Alpha
Centauri. So which is the better predictor of closeness, brightness or proper
motion? (Note that a star coming directly at us, or moving directly away from
us, would have no detectable proper motion, no matter how close it is.)

212

DOUBLE STARS
Double stars are pairs of stars that are apparently so close that it’s hard to distinguish them individually. Alpha Centauri turns out to be a double star. It
wasn’t originally thought that double stars were actually close to each other,
just that they were on the same line as seen from the Earth. However, when
astronomers started listing double stars, there turned out to be far too many
for random distribution of this sort. It seemed likely that many of the double
stars were actually part of the same system. Double stars that are bound
together in one system are called binary stars. Alpha Centauri is a binary, containing Alpha Centauri A and Alpha Centauri B.
Observation of a binary system gives us two more indicators to its distance
from our own solar system. The farther apart the two stars appear to be from
each other, the closer the system is likely to be to us. This likelihood is drawn
from the assumption that all binary stars are actually the same distance apart
from each other, which is obviously not true. However, it can serve as an indicator, especially when combined with other data.

A

NEW

SUN

A P P E N D I X

The second clue is that the more quickly they revolve around each other, the
closer they are likely to be to each other. (Mercury, very close to the Sun,
revolves around the Sun in 88 days — Earth days, that is. Jupiter takes almost
12 Earth years for the same revolution.)
Alpha Centauri A and B have one of the widest apparent separations and one
of the quickest revolutions (80 years) of all binary stars. The evidence mounted that Alpha Centauri is very close to us.

PARALLAX
As telescopes got better and better, it eventually became possible to measure
the parallax of closer stars. Parallax is a measure of how much an object
appears to shift, when the observer shifts position. In the case of stars, the only
way to measure perceivable parallax is to observe a star at two times in the year,
six months apart from each other, so that the Earth (and the observer) have
shifted from one side of the solar system to the other. In the 1830s Thomas
Henderson was able to measure Alpha Centauri’s parallax. He determined that
Alpha Centauri is 4.4 light-years away from us. (Remember that Alpha Centauri
is a binary, so sometimes Alpha Centauri A is closer to us, and sometimes Alpha
Centauri B is closer.) No star has since been found to be closer.

PROXIMA CENTAURI
Okay, there is one star closer. Sometimes. In 1913, Robert Innes discovered an
eleventh-magnitude star very close to the Alpha Centauri system, with high parallax. It is 0.15 light-years (a trillion miles, or more than 13,000 AUs*) from Alpha
Centauri A and B, but turns out to be part of the Alpha Centauri system,
nonetheless. Its orbit around the other two stars takes hundreds of thousands of
years; for now, it is closer to us than either Alpha Centauri A or B, by the same
0.15 light-years. Officially, it is Alpha Centauri C. Unofficially, it is Proxima
Centauri. We’ll keep calling Alpha Centauri a binary system, because Alpha
Centauri C is too far away, and too small, to materially affect the two larger stars.
* An AU is an astronomical unit, the distance from the Earth to the Sun.

LUMINOSITY
Once we determine the actual distance of a star, several other bits of data fall into
place. We can determine how bright the star actually is — its absolute magnitude
— by comparing its apparent magnitude from Earth and its distance. It turns out
that neither Alpha Centauri A nor Alpha Centauri B is among the stars with the
greatest absolute magnitude; their apparent brightness relies a great deal on how
close they are to us. For the sake of any colonization efforts, that turns out to be
a good thing — both stars have habitable zones (which isn’t to say that either star
has a planet orbiting it, much less one actually within the habitable zone).

MASS
214

The fact that Alpha Centauri is a binary system gives us a great deal more
information about its stars. We know how far away it is, so we can calculate
the average distance between Alpha Centauri A and Alpha Centauri B. If we
know this average distance and their period of revolution (how long it takes
them to complete one revolution around each other), we can determine the
total mass of the system. If we can measure how much each moves relative to
more distant stars, we can calculate which one is more massive, and by how
much. And if we know all of this, we can calculate whether their orbit around
each other is closer to a circle or to a long, narrow oval.

As you can see, the Sun and Alpha Centauri A are very similar to each other.
They are both G2 stars, which means that Alpha Centauri A has the same yellow color as the Sun. Alpha Centauri A is larger and brighter, but not by a great
deal. Anyone, or anything, comfortable with the Sun would probably be comfortable with Alpha Centauri A.
Alpha Centauri B is smaller and dimmer than the Sun. It is orange, rather than
yellow. Alpha Centauri C is a great deal smaller and dimmer than any of the
other three, and is red.

HABITABLE PLANETS
There are limits on the radius at which a planet habitable to mankind might orbit
a star. The brighter and hotter the star, the farther out a planet must be to be
habitable; the dimmer the star, the closer a planet must be. Alpha Centauri C can
have no habitable planets — any planet close enough for life-sustaining sunshine
would be quickly ripped apart by gravitational forces. Both Alpha Centauri A and
B could have habitable planets, if they weren’t part of a binary system.
But what effect might the two stars have on each other’s habitable planets?
As it happens, very little. If a planet were within either star’s habitable zone,
it would never come close enough to the other star to be materially affected
by it — its orbit would be stable. Take a look at the illustration of our solar
system, with the Alpha Centauri binary system superimposed on it. Mentally
replace the Sun with Alpha Centauri A. Alpha Centauri A’s habitable zone does
not reach much beyond the orbit of Mars, and any planet that close to Alpha
Centauri A is always too far from Alpha Centauri B to be affected by it.
Now mentally replace the Sun with Alpha Centauri B. Since Alpha Centauri B
is cooler than the Sun or Alpha Centauri A, its habitable zone is even closer to
Alpha Centauri B. Again, Alpha Centauri A would never come close enough to
perturb a habitable planet around Alpha Centauri B.
The same can not be said for planets at greater distances from either of the
binaries. Neither star can have a planet with the orbital radius of Jupiter,

A

NEW

SUN

215

Saturn, Uranus or Neptune. In fact, once beyond the radius of Mars, the only
stable orbits are those that circle both stars.
Even if neither star would perturb each other’s habitable planets, they would
still be clearly visible. From a planet circling Alpha Centauri A, Alpha Centauri
B would be a tiny, dazzlingly-bright yellow-orange light in the sky. It will be
a tiny dot, but not quite a point, and it would be far brighter than any full
moon — easily bright enough to read by. It would light up the night sides of
any moons in the sky, as Earth does to the Moon’s dark side if you look carefully when the Moon is a crescent. Depending on the geometry at any given
time, soon after sunset or before sunrise you night even see “double crescent”
moons! Alpha Centauri C would be just barely visible at darkest night as a red
naked-eye star from either Alpha Centauri A or B.

PLANETOGRAPHY
216

Both Alpha Centauri A and B can clearly support habitable planets. We are not
currently aware of any planets orbiting either or both of these stars (although
recent investigations using the Hubble telescope suggest that a giant planet
or a brown dwarf — a very small star — is orbiting Alpha Centauri C). However,
let’s assume a habitable planet orbits Alpha Centauri A. It should be named
Chiron, after the wisest of all the mythological Centaurs, and the tutor of
Achilles, Aesculapius and Hercules. However, anyone who lived there for long
might simply call it Planet.

EARTH COMPARISONS
Planet is quite a bit more massive than Earth, with a larger radius. While the
larger radius reduces the effects of gravity a certain amount, Planet’s greater
mass still creates a 30% greater gravitational pull — objects are 30% heavier
on Planet than on Earth. Planet is a bit farther from Alpha Centauri A than
Earth is from the Sun, but Alpha Centauri A is brighter than the Sun, and these
differences offset, so that Alpha Centauri A is almost exactly as bright from
Planet as the Sun is from Earth.

Planet’s days are only about 18 hours, so sleep cycles must be correspondingly reduced. Its years are slightly longer than Earth’s years., but not enough to
make a noticeable difference. The greater difference is Planet’s lack of seasons.
With only a slight axial tilt, any seasonal differences are minimal.
Neither of Planet’s moons exert as much tidal pull as Earth’s moon, but when
they combine, tides will run slightly higher than on Earth.
Once every 80 years, as Alpha Centauri B reaches perihelion (its closest
approach to Alpha Centauri A), it generates enough heat to increase Planet’s
average temperature by 0.3° C. That doesn’t seem like much, but Planet’s climactic system might easily amplify this to uncomfortable levels. In fact, any
life native to Planet may have evolved cyclic responses to this event.

ATMOSPHERIC COMPOSITION
The atmosphere consists of 90.9% Nitrogen, 8.5% Oxygen and .01% Carbon
Dioxide. The low oxygen content results in fewer forest fires, a higher proportion of anoxic (oxygen-free) environments — encouraging a large anaerobic
ecosystem reducing nitrates to break down organic matter — and a plant
ecosystem dominated by the need to conserve carbon.

METEOROLOGY AND CLIMATOLOGY
Planet’s larger size and gravity result in a significantly higher sea level pressure
than Earth’s: 1.74 atmospheres (that is, 74% greater air pressure at sea level
than on Earth). This brings the partial pressure of Oxygen (15k Pascals) up to
acceptable levels, but the high overall pressure combined with such a large
quantity of Nitrogen produces deadly Nitrogen narcosis in unprotected humans.
Human colonists would have to wear pressure helmets, at the very least.
The temperature bands running along the surface of Planet are the most obvious climactic pattern. As on Earth, solar energy warms the equatorial areas,
and the weather cools as you migrate towards the poles. Thus, equatorial
regions produce more energy, while the poles tend to have more mineral
resources.
The rainfall patterns of Planet depend on the wind currents, which always
blow from west to east. Since the wind carries moisture with it from the
oceans, rain tends to fall on the west side of mountain ranges. You can see
this trend when looking at a big continent — green predominates on the western coast, indicating a great deal of rainy or moist terrain, while the east coast
remains dry and barren. Rainfall determines the amount of nutrients that may
be collected, so often the west coast of a continent proves a better source of
nutrients than the east coast. On flat continents or small islands, no elevations
exist to trap the rainfall, and so moisture tends to be more evenly distributed.
Also, river valleys usually have a reasonable amount of rain, so a river running
through a dry area can be a good base location.
The warm tropical seas of Planet are breeding grounds for hurricanes, which
are also encouraged by the high gravity and rapid rotation. The dense nitrogen atmosphere only partly offsets this. The equatorial cloud belts, however,
help to regulate the climate by reflecting sunlight.

A

SUN

OCEANOGRAPHY
At over 20% higher insolation than Earth, Planet has very small polar ice caps.
The effect of this on the oceanic circulation is profound. Instead of cold oxygen-rich polar water sinking at the poles and being carried in a current along
the ocean floor to the equator (as on Earth today), the circulation is driven in
reverse, with warm saline oxygen-poor water sinking at the equator and flowing to the poles. As a result, the bottom waters have little oxygen.

SOIL COMPOSITION

220

Compared to Earth, silicates are much less common in the soils of Planet. As
in the tropics on Earth, warm water leaches the silica from clays, leaving a poor
alumina-rich soil. (This does not prevent rain forests from growing, but will
inhibit agriculture.) The arctic regions have a higher proportion of acidic soils
with a high proportion of organic matter (podzols) which is equally hard to
farm. The temperate soil zone, which on Earth is favoured with rich aluminosilicate clays, is much narrower on Planet, and the soils are more likely to
be sandy or lime-rich. Bogs are also common.

ECOLOGY
Although basically similar to Earth life, in that it is based on carbon compounds in water, the organisms of Planet have evolved a biochemistry very different from Earth. The scarcity of carbon in the environment, and of dioxygen
in the soil, has forced plants to try to make do without O2 (oxygen), and to
economize on the use of carbon in structural parts and as an energy storage
material. They do this by using a biochemical reaction unknown on Earth.
Planet’s plants seem to have a special enzyme to encourage this reaction, possibly with the aid of sunlight. They use the nitrate obtained this way to store
energy as organic nitro-compounds, to reduce carbonates to carbon, and to
carry out respiration in anoxic environments.

A

NEW

SUN

A P P E N D I X

5

The prevalence of anoxic (oxygen-free) environments rich in organic material,
combined with the presence everywhere on Planet of nitrated compounds, has
led to an astonishing variety of underground organisms which live in the
absence of oxygen (though they can use oxygen if it is present) and “breathe”
nitrate. This ecosystem apparently has symbiotic relations with the plants and
with Planet’s animal life. Also note that the prevalence of nitrate in the environment has serious repercussions.
Nitrous oxide is present in only small amounts as it combines with ozone in
the stratosphere to break down into N2 and O2 (which prevents the build-up
of an ozone layer).
When plant material is buried, nitro-hydrocarbons have all they need to
“burn,” so they do so slowly underground, leaving nothing behind until all the
reducing material (hydrocarbon) or all the oxidizing material (nitrate) has
gone. Nitrate nearly always runs out first, leaving a residue of carbon compounds. Provided this does not come into contact with oxygen, it fossilizes to
produce ordinary fossil fuels. Since Planet has been hot and hypoxic for a long
time, it should be expected to have all the oil, shale and coal anyone could
want, depending on the efficiency of the ecosystem.
Regardless of any attempt to wipe out the underground nitrate respirers, all
efforts to return carbon to the biosphere would encourage Planet life to proliferate. Conversely, the huge quantities of nitrate in the soil would be heaven
to human farmers.
However, water would have to be treated in order to remove the nitrates so
that it is safe to drink; otherwise humans would suffer from methhemoglobinemia, or “blue baby syndrome,” where the red blood cells are poisoned so
they can’t take up oxygen. The best way to treat this water is to pass ozone
through it to destroy the nitrate.

NATIVE LIFE
XENOFUNGUS
Xenofungus is a hard, crimson mass of tubular shoots ranging in size from about
a foot across to microscopic. It grows in huge, heaped tangles capable of covering thousands of square kilometers of land, with a depth ranging anywhere
from 2 to over 25 meters. Anything trying to move through a fungal area must
either have (a) the raw tonnage required to break through the mass, (b) the ability to move over its top without shredding itself or becoming bogged down in
the mass’s many cavities, or (c) the firepower simply to blast its way through.
Xenofungus also grows in the oceans. Sea fungus is a bit more diffuse than
the land stuff (tending to grow much taller, but not nearly as dense), but is
otherwise basically identical.

222

Most xenofungus blooms are thousands of years old, and geographically stable. On the rare occasions when they do appear, however, they literally appear
almost overnight, growing at a rate of up to a meter an hour, sprouting spontaneously over an area that can encompass hundreds of square kilometers.
Chemical analysis of the fungus indicates that it’s a rich source of trace elements
and rare minerals with a high potential value in energy, nutrient and mineral production. The only barrier to the full exploitation of the fungus as a natural
resource is the evolution of technologies to extract its benefits economically.
The fungus seems to exist in a semi-symbiotic relationship with the mind
worms (see Mind Worms, p. XX). Boils are often reported to originate from
fungus blooms, particularly when the blooms are somehow damaged. The
worms seems to provide the fungus with a natural defense.
One of the more mysterious and controversial aspects of the fungus is its
“song.” Certain individuals in the immediate proximity of fungal blooms (anywhere from 5 to 200 kilometers, depending on the individual and the size of
the bloom) claim to hear a sort of hum or ululation from the fungus. This
“music” is not audible to most, and it cannot be recorded. If it exists at all, it

A

may be a resonance created from the same “psychoactive” field that the mind
worms employ. Some (particularly among the Gaian faction, which believes
implicitly in the “Song of Planet” and has accorded it a mystical significance)
claim the song is ethereally beautiful. Others have alleged that prolonged
exposure can drive the human brain to distraction, or even madness.

MIND WORMS
The dominant land species on Chiron is the mind worm. From a distance, an
individual worm specimen, with an average length of 10cm, hardly seems a
threat. Get closer, however, and a human may experience the power of this
species. Visions of horrible tortures and frightful deaths assail the mind,
straight out of the victim’s worst nightmares. This effect multiplies with the
number of worms present, each individual adding its own voice to the attack.
With sufficient numbers, the victim goes numb with terror, causing spasms,
paralysis, and even death as the autonomous nervous system shuts down. This
attack is only a precursor to the worm’s main goal: to implant freshly hatched
larvae inside the host’s brain. One gravid worm, if sufficiently agitated, can
burrow through a human skull in thirty seconds — less, if the worm finds easy
entry through an eye socket or nasal passage. Once inside the brain casing, the
worm implants its ravenous larvae, which thrive and grow as they devour the
nutrient-rich tissue around them.
Adult mind worms live for less than a month (explaining their urgent need to
reproduce as quickly as possible), although they can enter a dormant state that
lasts for years when they are in contact with the xenofungus. They reproduce
sexually, but are hermaphroditic — each mind worm is capable of both impregnating another and of producing larvae itself. In particularly harsh environmental circumstances, a mind worm is even capable of impregnating itself.
Genetically, one mind worm is virtually indistinguishable from any other anywhere else on Planet, right down to the chromosomal level.
Giant swarms, or “boils,” of these mottled 10cm nightmares occasionally wriggle out of the fungal beds, attacking settlements and their outlying farms and

A

NEW

other enhancements. Victims are paralyzed with terror, and then experience an
unimaginably excruciating death as the worms burrow into the brain to implant
their ravenous larvae. Only the most disciplined security squads can overcome
their fear long enough to trigger the flame guns that can keep the worms at bay.
There is one advantage to destroying a mind worm boil (other than the
increased feeling of security). When mind worms combine into boils, their
metabolisms change. A few begin building concentrated deposits of rare elements, and when a mind worm boil’s “life” is cut short (for example, when one
is flamed), these deposits can be recovered and converted directly into energy
stores. The value of these deposits, and their mode of recovery, lead to their
informal name — planetpearls. Mind worms that naturally dissipate do not
leave the “husks” in which planetpearls are found — they are only recoverable
if the boil is “killed.”

224

There are three distinct vectors of the mind worm boils — land, sea and air.
The aquatic vector, dubbed isles of the deep, appears to form when suboceanic worms come together into a boil. The biochemical processes of the boil
itself produce sufficient gas to make the mass buoyant, causing it to rise to
the surface. At that point it takes on a life of its own, including apparent independent movement, and even the ability to perceive and pursue particularly
attractive food sources (like human vessels and sea colonies). Isles of the deep
in shallow coastal waters have been known to spawn land-based boils that
break off from the mother mass and proceed on their own cross-country
hunts.
The final vector, the air-borne Locusts of Chiron, is the strangest. Periodically,
a pre-boil mass of mind worms in a xenofungal bloom spontaneously, and for
unknown reason, metamorphoses so that they all grow wings, whereupon the
worms take off as a boil-swarm. Locusts of Chiron are rare, and “wild” locusts
are rarely seen outside of periods of unusual mind worm activity.
There are three current theories regarding the nature of the mind worms’
attack. One depends on biochemistry, suggesting that the species produces
some pheromone-like atmospheric chemical which induces hallucinations in

A

NEW

SUN

A P P E N D I X

the human brain. A second, more exotic explanation has also been posited,
that the worms manipulate electromagnetic radiation to attack. The third theory is that the mind worms are able to manipulate a totally new form of energy — a purely psychoactive waveform capable of interfacing with, and distorting the thoughts of, all self-aware creatures.

PLANT LIFE
The bulk of the biomass of Planet, however, consists of basically earthlike
green vegetation — algae, fungi and small plants, the most complex of which
can be compared to a terrestrial palm tree. Over most of Planet, this vegetation takes the form of a savanna-like carpet of grass and moss, with the occasional “vine” or small “bush” relieving the monotony. The sole exception to
this rule is the Monsoon Jungle, where anomalous green vegetation can reach
a height of several dozen meters. Whatever its size, however, the green biomass provides many useful proteins that can be efficiently processed for use
by humans as nutrients.

SYMBIOSIS
Despite the most obvious life-forms (xenofungus and mind worms), life on
Planet, in general, is neither hostile to humankind nor particularly noteworthy.
However, the intricate and sophisticated symbiosis in which nearly every
species participates is noteworthy. (In fact, no observed species, whether flora,
fauna or otherwise, does not participate in this symbiotic dance.) It is common
on Earth for two, or sometimes even three or four species, to engage in a symbiotic relationship. On Planet, the symbiotic network essentially embraces
every native species. This network works together with extreme efficiency and
produces very little organic residue — everything is used, then reused.
Therefore, contrary to planetologists’ expectations, fossil fuels and the like are
unknown on Planet.
It is not too great a stretch to suggest that this intricate network has been
woven by conscious intent (without attempting to answer the obvious rejoinder, “Whose intent?”).

OTHER PLANETS
Alpha Centauri B has been dubbed “Hercules” by the inhabitants of Planet. As
myth would have it, Hercules was, as much by fortune as by intent, a great
nemesis of the Centaurs. He slew Nessus (for attempting to violate Deianira),
Eurytion (for attempting to force a marriage with Dexamenus’ daughter,
Mnesimache) and even his former tutor Chiron (by accident, with a poison
arrow). Pholus was killed indirectly — by foolishly picking up Hercules’ arrow
and dropping it on his toe! Since Alpha Centauri B must either have ejected
or prevented the formation of other planets in this system, and could in time
be responsible for disrupting the remaining planets, the name is appropriate.
Eurytion (named after one of the Centaurs mentioned above) orbits Alpha
Centauri A at about half the radius of Planet. Among the planets orbiting the
Sun, Mercury bears the closest similarity to it.

dated aspects of Asimov’s book are well addressed at this site. It contains plenty
of current statistics and other data, covering much more than just Alpha Centauri
(a good place to start might be their search engine, at www.nasa.gov/search/). It
also includes an “Ask the Astronomer” question-and-answer forum, plus an

Sagan’s clear vision of humanity’s future in space makes this worth reading
cover to cover, not to mention the great pictures.

FICTION

228

Much inspiration for Alpha Centauri came from reading classic works of science fiction. For those interested in reading some great books, Alpha Centauri
Designer Brian Reynolds offers the following suggested reading list.
THE JESUS INCIDENT Frank Herbert
A speculative and philosophical tour de force by my favorite science fiction
author. You’ll probably have to search used bookstores for this one, but it’s
well worth it. My favorite science fiction novel ever. A clear inspiration for the
story of Planet.
DUNE Frank Herbert
Herbert’s more famous masterpiece. If you enjoy stories of human factions
tearing at each others’ throats, you’ll love this.
A FIRE UPON THE DEEP Vernor Vinge
A far future epic which includes one of the more interesting alien races I’ve
encountered as well as some really original future concepts and a surprise ending which brings it all together. Also includes some pretty hilarious parodies of
internet newsgroups.

ANVIL OF STARS Greg Bear
What if the universe is filled with alien races sometimes even more sinister and
diabolical than humanity at its worst? To what depths of deception and atrocity will a species descend in order to secure its survival?
SLANT Greg Bear
A near future earth where information technology has continued to make
quantum advances. I find suspension of disbelief very easy with Greg Bear,
because his worlds are coherent and his characters’ motives are so plausible.
THE MOTE IN GOD’S EYE Larry Niven and Jerry Pournelle
The best book I’ve read on the classic “first contact” concept. A really in-depth
study of what makes an alien race tick.
THE REAL STORY Stephen R. Donaldson
The first in a series of five. Mostly notable for the amount of sleep I lost reading it. Donaldson is the only author I know who can keep me addicted and on
the edge of my seat through five straight books.
RED MARS Kim Stanley Robinson
The characters can get a little thin, but this is the story on terraforming another world. Extremely well-researched. Hard science fiction at its hardest.
THE YEAR’S BEST SCIENCE FICTION Ed. Gardner Dozois
An annual collection. Extremely well-chosen and well-edited. My favorite
source of science fiction short stories. I take one with me on summer vacation.

JOURNEY TO CENTAURI (EXCERPT)
The following is an excerpt from the web-based episodic story, Journey to
Centauri, that appeared on the Alpha Centauri website beginning June 1,
1998, written by Michael Ely. Visit the Alpha Centauri website at www.alphacentauri.com to find out more about humanity’s journey to the New World.
“Captain.”
Shapes. Shadows, hovering over him. A sense of threat, darkness eclipsing his
vision, and the distant sound of warning klaxons. He tried to lift his hands and
could not, tried to speak and felt his throat turn to fire. A deep cold pressed
down on him, crushing his bones to ice.
“… this one … hurry!” The voice again.

230

More movement, seen through layers of frost and glass. I am the Captain,
came his next thought, sharp and coherent. I should be first ….
First out of the sleep. Visions returned to him: the long rough cylinder of the
ship, floating above the chaos of Earth. The massive cryobays with their rows
of sleeping crew, the white-suited cryotechs moving ghostlike among them.
His last memory of lying down in glass and feeling the blue tide rise to swallow him, forty years and a moment of darkness ago. Thinking, hoping, that
when he woke again, it would be to the sight of Alpha Centauri’s primary
cresting the rim of a new planet, a new world.
But now … something was wrong. Someone, unauthorized, moving around
the ship. A wave of dizziness washed over him and his vision blurred into a sea
of blue, red lights flashing in the distance. He could feel the ship shaking
beneath him.
“We move …”
A shadow passed over him, and then another. Footsteps retreated. He stared
up through the curved top of the cryocell, willing himself into the open spaces
of the ship, trying to force his fingers to move. His brain signaled alarm but
his heart and muscles, held in near stasis, would not respond.

He waited, helpless, while the ship hurled on and the warning klaxons sounded their three beat sequence.
After interminable moments he heard a click and a hiss, and then a storm
exploded beneath him.

Pravin Lal awakened to the hiss of the transparent capsule door breaking its
seal and the feel of the ship’s foundation shaking beneath him. His heart
began to pound and he closed his eyes, breathing deeply, seeking calm.
When his heartbeat slowed he opened his eyes once more. His training had prepared him for this: disorientation, sleep sickness, a deep fatigue that seemed to
nest in his bones. He spit the respirator from his mouth and pulled the IVs from
his arm, then lifted his hands, placed them on the glass lid above, and pushed.
The cryocell opened. He was alive.
Around him stretched the expanse of Cryobay Two, silent and vast, filled with
over a thousand identical glass capsules, each one bathed in a pale blue light,
each with tubes and cables snaking down to conduits in the floor. Over a
thousand crew, but his eyes immediately, reflexively, turned to the cell at his
left. He climbed to his feet and, ignoring the chill, crossed to it.
He looked down through the glass. There, beneath the frost and bluish tint of
the cryogel, he could make out her soft brown shape, indistinct, and the dark-

ness of her long hair. Pria. She looked so peaceful, so far away … he still
remembered her gentleness, and their last strong kiss before the cryotechs
closed the cell, locking her away from him.
His practiced eyes scanned the small console above her cell. Everything
appeared normal; she had survived. His eyes flickered once across the manual
release key, and then he saw the red warning lights flashing at the far end of
the cryobay. The ship … he had almost forgotten the danger. He brushed Pria’s
cell with his fingers one more time and then turned away.
From a metal shelf at the foot of his vacated cell he lifted a folded uniform …
sleek, comfortable, in the sky blue of the mission’s Chief of Surgery, with the
U.N. seal on the breast and no country-of-origin markings visible. The Captain
had lobbied strongly for that.

232

He slipped into the uniform and flipped on the small computer sewn into the
uniform’s sleeve. Status report: the Captain would emerge from cryosleep
shortly, along with other core officers and some emergency support staff. It
appeared that large portions of the ship’s hull had been damaged, along with
two of the three hydroponics modules. The fusion drive had shut down.
Pravin entered the Returned to Duty code and headed for the command bay.
The ship was racing towards Centauri system at tremendous speed, and without the fusion drive there was no way to stop.
Log Entry Received,
Pravin Lal, Chief of Surgery.
I have awakened to find the mission in jeopardy. I go now to join
my Captain in the command bay, ready to learn what has gone awry.
I pray the integrity of the ship’s datacore remains true. It is the last
hope of humankind...all of our knowledge digitized for transit to
the new world. If Earth has not survived these last 40 years, then
our future lies in the heart of this damaged ship.

The lid to his cryocell hissed open, and Sheng-ji Yang emerged into darkness
and immediate danger. From the shadows surrounding his cell peered the narrow deadly eyes of shredder pistols, their barrels leveled directly at him.
Sheng-ji stood calmly, using his hand against the cryocell to steady himself as
waves of post-sleep nausea washed over him. No weakness … his eyes flickered in the darkness, marking the position of every enemy. He could not see
their faces … the main lights in this bay appeared to be malfunctioning, or
shut down, and he could see only the other cryocells with their soft blue glow,
like phosphorescent flowers in a field of darkness.
He willed his muscles to relax with exquisite control. His eyes flickered, just
once, across the black metal lockbox on the shelf at the foot of his cryocell.
He wouldn’t betray his intentions by looking at the box again, but in his mind
he carefully reconstructed the exact positioning of the box on the shelf, its
exact height from the floor and the position of the softly glowing shape of the
digital print lock. The lockbox carried his personal arsenal: his shredder pistol,
a submission rod and several sets of organic restraints.
“Move away from the cell. Follow the exact path we have laid for you.” came a
harsh, gravelly voice from a knot of shadows only two cells away. He looked down
to see small glowing blue dots on the floor leading away from his cryocell. Why?
“On whose orders?” he asked, his throat husky from disuse … let the games begin.
“Do not answer him,” came a soft, steely voice from a position, amazingly,
even closer than the other, a peculiar dark knot of shadows barely an arm’s
length away. A chill crossed him, briefly … that this person dared to crouch so
close to him. He read the shadows quickly, making out a silhouette. The shadow … this person … waited with catlike alertness, spine taut as a wire. Who?
“Do not answer this man,” the voice continued. “You are forbidden to speak
to him. And, Doctor Yang, do not speak to them. Simply follow the path we
have laid out for you.”
“Am I to …”

Suddenly the shadow exploded into motion, and a black serpent crossed the distance to Yang in a heartbeat. Yang felt red hot wires of pain lace his neck, and
he fell to his knees, cursing the post-sleep weakness that dulled his reflexes.
Psych-whip, a part of him thought calmly. They have been in the armory. And
then he smiled as the pain intensified … he welcomed it, opened himself to it,
letting it dance on his nerves and dissolve into his spine. Pain, awaken me ….
“We mean you no immediate harm, but I know of your special talents. You
must follow my instructions. Do not speak. Crawl along the blue lines.”
He looked at the blue dots on the floor, his head still swimming. His eyes flickered up to one corner of the room, a zone of darkness with the vague sense
of a metal bulkhead curving. In that darkness he could imagine the bland silvery eye of the security camera staring down at him, but it could not see into
the far corner, where the blue dots led.

234

He felt the muscles tighten along his back. He felt the cool metal floor beneath
his hands.
Abruptly, he stood. Electric tension jolted across the room as shredder pistols
twitched to follow him. He could smell the uncertainty … should we fire? …
and it had the metallic tang of fear.
He took one slow pace along the blue dots, shuffling as if from fatigue, and then
every muscle in his body exploded backward toward his cryocell as a yell from
the bottom of his lungs split the darkness. One roll and he reached back over his
head to take the black metal lockbox into his hands … no wasted motion, no
wasted time. He had already seen the action in his mind. And then …
… no turning back, but instead he went up and over his cryocell, the blue light
illuminating him for just a moment. A burst of shredder pistol fire crossed the darkness, humming in a cloud all around him, liquefying the glass beneath his feet,
and as he leapt he felt the sharp stinging pain of the psyche whip on his back.
A wave of nausea overtook him and instead of fighting it he used it, followed
it down, his body spiraling drunkenly into the space behind his cryocell. He

could feel the confusion in the room as shadows lurched forward, orders issued
in hisses. No shouts and no further fire … near perfect silence, he thought.
Amazing discipline, as if ….
No matter. He had moments, and moments were all he needed. Crouched in
the darkness he punched the release code into his lockbox. He flexed his
hands, deadly weapons in their own right, serpents awaiting their venom.
The box would not open. It remained inert, a block of dead cold metal in his
hands. He turned it quickly face up, tried to make out the letters printed on
top. “A. Shaw.” They had switched lockboxes on him.
A shadowy form rose above him, and he caught a sliver of blue light across
familiar features.
“You …” he said, wanting to buy time.
A dark metal shape crashed into him, and his vision burst into blue fireworks
on a night black sky.

DESIGNER’S NOTES
Although this is our second product as a company, Alpha Centauri has been
around, in some form or another, right from the humble beginnings of FIRAXIS Games. Its story has in many ways paralleled the story of our company —
FIRAXIS and Alpha Centauri grew together, both changing and evolving over
two and a half years. Both faced significant setbacks and periods of self-doubt,
but in the end FIRAXIS came together as a company, and as you have hopefully discovered, Alpha Centauri came together as one of our best games ever.
In July 1996, the brand new FIRAXIS Games (at the time we were calling it
“FIRAXIS Software”) consisted of four or five people huddled in some borrowed office space in the back of the Absolute Quality building in Hunt Valley,
MD. AQ, a professional game testing company, was also a brand new startup,
so times were exciting, to say the least. Yes, the rumors are true: we did in fact
buy AQ a phone system and bartered it for their spare office space.

236

CEO Jeff Briggs worked the phones to rustle up some funding and did all the
hard work of actually putting a new company together. Sid Meier and Brian
Reynolds worked to scrape together some playable prototype code, and Jason
Coleman wrote the first lines of JACKAL, the engine which these days pretty
much holds everything together. Office Manager Susan Brookins found us
some office furniture and bought crates of Coke, Sprite and Dr. Pepper to stash
in a mini-fridge Brian had saved from his college days. We remembered that
at some indeterminate point in the past we were considered world class game
designers, but our day-to-day lives weren’t providing us a lot of positive reinforcement on that point. So for the first nine months of our existence as a
company, we clunked over the railroad tracks in the morning, played Spy
Hunter in the upstairs kitchen, and declared “work at home” days when AQ
had competitors in the office.
1996, you may recall, was also the “Year Of The Real Time Strategy Game.”
Giants strode the industry and remade it in their image. Indeed, our first offering as a company, Sid Meier’s Gettysburg, is enthusiastically real time, and if

A

you like real time games at all and haven’t tried it yet you owe it to yourself to
go and find a copy — Sid considers it one of the two best games he’s ever
designed, and the rest of us are inclined to agree. But we were also convinced
that in spite of the industry’s headlong rush to get on the real time bandwagon, a strong market still existed for turn-based strategy games. Gamers wanted
a new, sweeping epic of a turn-based game, and they wanted us to design it.
At that time, science fiction games were definitely not the first thing that
came to mind when you thought about our team. We were known for history-based games. We knew a lot about history and historical games and pretty
much left the science fiction and fantasy to everyone else. But we’d just done
an epic game based on all of human history up to present times and needed
a fresh topic, so at some point someone said “well, how about a future history” — human history from the near to the distant future. Kind of a way to
bring our strength with historical games to bear on a science fiction game.
From the beginning, Alpha Centauri set out to capture the whole sweep of
humanity’s future. Not just technology and futuristic warfare, but social and
economic development, the future of the human condition, spirituality and
philosophy. One challenge we quickly discovered is that whereas most people
are at least roughly familiar with the major events of human history, and can
easily relate to archetypes like “fire,” “nomadic hordes” and “the wheel,” they
haven’t got the foggiest notion of what “Polymorphic Software” might be,
since we just made the name up five minutes ago. It takes a lot of work to
weave a tapestry of future history which both coheres and makes the future
accessible to players.
Since it is, after all, the future we’re talking about, we’ve tried to be extraordinarily flexible in allowing many different possible strategies and different kinds
of victory. Whereas we can, for instance, look back on the past and say “well
obviously that system of government worked and that one didn’t,” it’s a lot
harder to make cogent predictions about future society. We don’t even know
what future governments will be like, let alone whether or not they will work.
So in our Social Engineering section we’ve tried to challenge players to imag-

ine the future for themselves — to create their own future utopias and try them
out against other competing visions. Thence also came the idea of “factions,”
rival groups to challenge players with opposing and contrasting ideologies.
Thrown into this mix are the uniquely science fiction elements of exploring
and terraforming an alien world. Since we were trying to create a plausible
future history, trans-lightspeed galactic travel seemed a bit unrealistic. We
chose instead to start with a near future situation which with only a little extra
optimism could actually happen — a human mission to colonize the solar system of our sun’s nearest neighbor. It seemed likewise implausible that upon
arriving in the Alpha Centauri system humans would discover a thriving community of five or six intelligent quasi-humanoid alien races, so we stuck with
human factions to provide rivals and opponents. But alien ecologies and mysterious intelligences are cool, so we’ve incorporated them into the game as
external “natural forces” which serves as a flywheel for much of our back-story
and a catalyst for many player actions.

With Gettysburg taking up most of our time, we spent Alpha Centauri’s first
year working up a prototype of basic ideas. Artist Mike Bazzell provided enough
preliminary art to get us going, senior programmer Jason Coleman perfected
our system code, and lead designer Brian Reynolds hacked a game and some
AI together. Sid had a spare fractal algorithm he wasn’t going to need for
Gettysburg, so Brian took it up to Canada for vacation and finished the world
generator on the shores of the St. Lawrence. We were playing “games” of Alpha
Centauri by fall of ’96, and by the following summer we were working on the
multiplayer engine. We invited veteran game designer Doug Kaufman, with
whom we’ve often worked, to join us as a game balancer and become “the first
man on Alpha Centauri.” You’ll find Doug’s ideas well represented throughout
the game (the disengage rule, long range bombardment, and energy loans, to
name just a few), and he’s the guy you can thank when you try some bizarre
new strategy and lo-and-behold the game understands it.
Around this time we also began doing some research on the scientific realities
involved in interstellar travel. A few tentative posts on the Internet later, we

A

made the acquaintance of Derek “Del” Cotter, a British fan who proved so helpful in setting us straight on astronomy, biology and interstellar travel that we
sent him a contract and hired him to do some research. Del provided the technical design for our starship, the U.N.S. Unity; designed planets and solar system consistent with current knowledge of the Alpha Centauri system; figured
out Planet’s vital statistics; and fleshed out our biosphere. Del’s interstellar travel research was particularly useful for our web story, which Mike Ely wrote and
which appeared in installments on our website during the final months of
development. Del even provided some biochemical theories about how the fungus and mind worms might work and generally made it possible for us to do a
near future space colonization game without sounding like idiots.
Now skip ahead to late 1997. Alpha Centauri was still plodding along, but the
schedule was starting to slip and most who played it at the time agreed that
it lacked that certain je ne sais quoi which makes a game stand out as a classic. Enter Bing Gordon, an industry veteran who co-founded Electronic Arts
way back when your humble game designer was just starting high school (you
mean he’s one of the guys who brought out Archon?! Cool!) and who lately
serves as its Chief Creative Officer. A long time fan of, um, that other game we
wrote, he was excited about working with us on our new project. He saw in
Alpha Centauri a masterpiece struggling to get out. Bing helped us figure out
what was needed to make this the cool thing we all knew it could be. In addition to the fact that we didn’t throw the whole game out the window in disgust, you can thank Bing for the Planetary Council and all the extra time we
spent making the diplomacy cool. Bing also convinced us to take multiplayer
seriously as a design challenge as well as a technical hurdle.
A few months before the 1998 E3, the gaming industry’s biggest trade show, it
was time to get our marketing plan up to speed. Lindsay Riehl, our one-woman
marketing department, quickly got this under control, kept the press interested
in our progress, and generally helped spread the good news. It was Lindsay who
talked us into including Explore/Discover/Build/Conquer in the game as well as
the ad campaign, so that what began as a cool marketing tie-in ended up
becoming a way to refocus our “Governor” automation (which had previously

A

been intended mainly for advanced players) as a useful learning tool for beginners. Later, Lindsay arranged to fly out EA’s marketing team for several days of
hands-on play, in a devious, underhanded and ultimately completely successful
ploy to hook them on the game and remake them as Alpha Centauri evangelists. Many thanks to Alex Carloss, Chris Plummer, Matt Orlich, Audrey Meehan
and David Swofford for all the hard work they’ve put in, and most especially for
taking the time to come out and really get to know us and our product.

Alpha Centauri showed well at E3, so it was time to buckle down and get this
bad boy finished. How Jason “90-hour week” Coleman and Artist Dave “I’m
very afraid” Inscore made it through the summer and autumn of ’98 is anybody’s guess, but in the end they proved to us that a Sid Meier game can have
an interface as polished and integrated as anything in the industry. Producer
Tim Train took on the near impossible task of keeping track of what everyone
was doing and making a (gasp) schedule, meanwhile coordinating the game
manual and foreign language translations and moonlighting as co-designer.
On top of all that Tim somehow found time to become our office Alpha
Centauri champion and provide innumerable good pointers on game tactics
for us to include in the AI. When a computer player amasses an overwhelming force and then moves up to attack your bases, think of Tim.
Art Director Michael Haire developed some concept sketches for our faction
leaders, and Jerome Atherholt painted those beautiful portraits which brought
them to life as individuals. Believe me there were a lot of people hovering around
his office door the day he was working on Deirdre (by the way, that’s pronounced “DEE druh.” Got it? Now say it again ten times). He also dug up and/or
manufactured all of those dossier photos, and most importantly took on the
scary task of designing the final look of Planet itself, drawing all of our terrain,
solar collectors, boreholes and so forth. We discovered that everyone had a
strong (and different) opinion on what Planet ought to look like (More red! Less
red! More detail! Less detail!), and finally one day Executive Producer Jeff Briggs
threw us all out and said “Okay, go home. This weekend Jerome is going to draw
the terrain, and when he’s done you can all look at it.” You done good, Jerome.

Mike Bazzell, in addition to doing pretty much all of our prototype art and
having by far the scariest office at FIRAXIS, built all of those cool vehicles and
vehicle parts. Imagine being told you have to design a laser cannon that looks
just as cool on a hovertank as on a needlejet or a cruiser, or carried around by
some infantry guys. And everything has to fit together interchangeably. And
rotate! And move in 3-D! But after years of playing with little “sprite guys,” it
sure is great to watch those needlejets make bank turns. Mike is also responsible for all of our on-screen animations, explosions and so forth.
Meanwhile, Mike Ely directed our Secret Projects movies, coming up with a
coherent vision, doing storyboards, figuring out which movies needed licensed
footage and which we should develop in-house, and working with the artists
to bring Planet to life cinematically. Mike made all of the “footage” movies
himself, and edited together the final cuts of all the movies. For the 3-D
movies, Nick Rusko-Berger was our principal movie man, creating our Opening
and Transcendence sequences as well as many of the Secret Projects, such as
the Bulk Matter Transmitter. But many of our other artists were heavily
involved in movie making as well — Greg Foertsch’s movies included the Space
Elevator and Hunter-Seeker Algorithm; Dave Inscore created the Command
Nexus and Maritime Control Center; and Jerome Atherholt painted the backgrounds for the Citizens’ Defense Force.
Music for our movies was composed by Jeff Briggs, our versatile CEO,
Executive Producer, Designer and Composer. Dave “Mr. Sound Guy” Evans, our
digital sound wizard and mandolin maestro, masterminded our in-game music
and did pretty much everything else that involves sound and sound effects.
Dave wrote what we suspect may be the first true interactive midi/pcm engine
ever to ship with a computer game. He had the fun of going to a sound workshop where everyone was talking about interactive midi as something “a few
years down the road” and thinking “heh heh, I’ve already done that.” Dave also
came up with some literally unspeakable technology to let us support true
voice-to-voice transmissions during multiplayer games. Meanwhile, Mike Ely
went through unending grueling casting sessions to find us seven faction
leaders with good voices, acting skills, and authentic accents. Want to make
Mike wince? Just sing a few bars of the “Deirdre’s got a Network Node” song.

Much still remained to be polished. Art Director Michael Haire designed the faction icons and created individual icons for each of our many technologies, facilities and secret projects. Michael also did many of our scoring screens, as well as
prototyping much of our interface. Greg Foertsch created our “monument”
reward screen, and did much of our situational payoff art. And while all this was
going on, a college senior and mathematics major walked into his career counselor’s office and said that what he really wanted to do with his life was “work
for a company called FIRAXIS Games.” And that’s how Chris Pine came to FIRAXIS. Chris did all the report screens on the HQ Menu, and we have to say we had
no idea how cool report screens could be until Chris joined us. Now if he’d just
give up this “Go” business and learn to play Chess like a normal Firaxian!

242

With Alpha Centauri pulling into the home stretch, Jeff Morris, our Quality
Assurance Director, kicked into high gear. Somehow Jeff managed to coordinate testing between three different groups plus FIRAXIS itself, keep our networks running, and still find time to write our install program. Our old sister
company, Absolute Quality, with whom we shared office space for so long,
handled the on-site testing, and we must say that Dan Schlueter and his team
did an excellent job finding the serious problems in our software. Dan, along
with colleagues Jim Smith, Ted Paulsen, Graham Boyanich, Ray Lofton and
Charles Brubaker, stayed on top of things and helped us get the multiplayer
code stable in record time. Origin also contributed Rhea Shelley’s test team,
which did a most thorough job of combing through the software for the
things that are so easy to miss. Thanks!
We’d also like to thank profusely the 25 hardy volunteers who participated in
our public beta test. Particularly considering that their only pay consisted of
buggy early versions of the game, their enthusiasm and participation was outstanding. We’d never done a public beta test before, but let me tell you we’re
sold on the idea now, since doing one gave us a perspective on our product
we could never have obtained in any other way. Among many other useful
suggestions, our beta testers insisted that we add Diplomatic and Economic
victories, and yes, even the dreaded Random Events. Thanks to everyone who
participated — you really made a difference.

Two and a half years is a long time to work on a project, and many changes
have taken place in that time. Amanda Rusko-Berger, Coulby Riehl and Caleb
Reynolds were all born during the project. Susan Brookins, who kept us fed
and paid and made sure the Gatorade man filled up our machine every week,
is now Susan Meier (yes, that Meier). The FIRAXIS staff has grown to a whopping 17, and we’ve got a pretty good view now from the top floor of the
Executive Plaza building in Hunt Valley. We’re a better team, a happier team,
and definitely a wiser team than we were when we started the project. The
nest is going to seem a little empty with Alpha Centauri gone, but fortunately
we’ve got two outstanding ideas in the works, and maybe even a few after
that, so it looks like we’ll stay busy for quite a while.
Before we close, we’d like to stop and briefly reflect on the deeper message
that Alpha Centauri hopes to convey. In the closing years of the twentieth
century, humanity stands capable of technological achievements which were
never possible in any previous era and which as far as we know may never have
been available to any sentient species, ever. The time of miracles is indeed
upon us, and yet the nuclear trigger remains armed, population growth continues to overwhelm available resources, our climate shows early signs of running amok, and sooner or later a near-Earth asteroid will probably wipe civilization or even humanity itself from the face of the planet. As a basket in
which to keep all our eggs, Earth is more precarious than ever, yet we continue to dilly and dally and just this week Time magazine ran an article calling
the International Space Station “a white elephant” that is not worth the
money.
Are we content to stew in our collective juices, to turn inward as our planet
runs inexorably out of resources and wait for the Universe (or perhaps our
next-door neighbors) to grow tired of us and wipe us out? Or shall we claim
the planets and stars, distribute our eggs among many baskets, ensure the
long-term survival of our species, and in the process embark on the greatest
adventure of all time? Mars could be reached within our own lifetimes:
manned exploration missions, even colonies, all for a minute fraction of what
we spend every year building weapons. The planets lie nearly within reach of

current technology, and even a trip to Alpha Centauri is easier than you probably think. Consider Planet’s final imperative at the Ascent to Transcendence:
bright children of the stars. We can probably eventually do even that if we put
our minds to It — what a thought! The stars are waiting for us; we have only
to decide that it’s worth the effort to go there. Look at the stars on a cold,
clear, winter night and think about that. If Alpha Centauri inspires a few
young scientists and astronauts; if it convinces a few more citizens to write to
their congressmen and work to rejuvenate our space program, humanity’s
space program, that will surely be its greatest and most lasting accomplishment.

244

And so to end our valedictory, we’d like to thank Sid for all his sage advice;
Jeff Briggs for thinking that starting a little company called FIRAXIS might
actually be a good idea; Jill Reynolds, Holly Coleman, Yvette Bazzell and all
the other FIRAXIS wives and families for enduring 80-hour weeks for longer
than anyone should have to endure them; our publisher for bearing with us;
and all the others, too numerous to name individually, for working to help
make this game great. Thank you, thank you very much. Most of all, we’d like
to thank all of our fans, who in the end make all of this possible. As always,
we hope you enjoy playing Alpha Centauri as much as we enjoyed creating it.
Walk with Planet!
