EarthSpaceColonies is a strategy-simulation game where you build space colonies around the Solar system. Your first destination is Mars. You need to establish a first self-sustaining colony and terraform a red wasteland into a green oasis. You need to balance your resources and expand the infrastructure. You can build anything from high-tech factories, hotels, military bases to space elevators, and terraformers. You can colonize other worlds as well: defend a mining colony on a dwarf planet Ceres and explore the subsurface ocean on Ganymede, Jupiter’s largest moon. You are challenged to survive intense combat on Saturn's moon Titan.
