Sid Meier’s Alpha Centauri

About Sid Meier’s Alpha Centauri

Sid Meier's Alpha Centauri is a 4X video game, considered a spiritual sequel to the Civilization series. Set in a science fiction depiction of the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron ("Planet") in the Alpha Centauri star system. As the game progresses, Planet's growing sentience becomes a formidable obstacle to the human colonists.

Alpha Centauri features improvements on Civilization II's game engine, including simultaneous multiplay, social engineering, climate, customizable units, alien native life, additional diplomatic and spy options, additional ways to win, and greater mod-ability. Alien Crossfire introduces five new human and two non-human factions, as well as additional technologies, facilities, secret projects, native life, unit abilities, and a victory condition.

Space-race victories in the Civilization series conclude with a journey to Alpha Centauri. Beginning with that premise the Alpha Centauri narrative starts in the 22nd century, after the 2060 launch of the United Nations colonization mission "Unity" to Alpha Centauri's planet Chiron ("Planet"). Unbeknownst to humans, advanced extraterrestrials ("Progenitors") had been conducting experiments in vast distributed nervous systems, culminating in a planetary biosphere-sized presentient nervous system ("Manifold") on Chiron, leaving behind monoliths and artifacts on Chiron to guide and examine the system's growth. Immediately prior to the start of the game, a reactor malfunction on the Unity spacecraft wakes the crew and colonists early and irreparably severs communications with Earth. After the captain is assassinated, the most powerful leaders on board build ideological factions with dedicated followers, conflicting agendas for the future of mankind, and "desperately serious" commitments. As the ship breaks up, seven escape pods, each containing a faction, are scattered across Planet.

In the Alien Crossfire expansion pack, players learn that alien experiments led to disastrous consequences at Tau Ceti, creating a hundred-million-year evolutionary cycle that ended with the eradication of most complex animal life in several neighboring inhabited star systems. After the disaster (referred to by Progenitors as "Tau Ceti Flowering"), the Progenitors split into two factions: Manifold Caretakers, opposed to further experimentation and dedicated to preventing another Flowering; and Manifold Usurpers, favoring further experimentation and intending to induce a controlled Flowering in Alpha Centauri's Planet. In Alien Crossfire, these factions compete along with the human factions for control over the destiny of Chiron.

Alpha Centauri, a turn-based strategy game with a hard science fiction setting, is played from an isometric perspective. Many game features from Civilization II are present, but renamed or slightly tweaked: players establish bases (Civilization II's cities), build facilities (buildings) and secret projects (Wonders of the World), explore territory, research technology, and conquer other factions (civilizations). In addition to conquering all non-allied factions, players may also win by obtaining votes from three-quarters of the total population (similar to Civilization IV's Diplomatic victory), "cornering the Global Energy Market", completing the Ascent to Transcendence secret project, or for alien factions, constructing six Subspace Generators.
