After a spaceship disguised as a meteorite lands on the planet of the Blupi, strange events occur as an evil robot takes over the entire planet with his machines. The game is a real-time strategy game set over 30 missions. Players use point and click controls to issue commands to the Blupi to gather resources such as wood, stone, and ore, construct buildings using those resources, and build weapons and vehicles to fight the robots. The game features additional mission objectives, including to secure camps, rescue captured Blupis, and protect from hazards including forest fires. Planet Blupi contains a level editor allowing players to craft their own maps and mission objectives.
