Discover a new generated world each time you play. Build colonies in biomes ranging from desert to jungle to tundra, each with unique flora and fauna. Manage and develop colonists with unique backstories, traits, and skills. Learn to play easily with the help of an intelligent and unobtrusive AI tutor.Read more
