Description from the publisher: From the colonies of Mars to the orbital stations of Earth and to the outposts on Jupiter, the cry is heard, Free Mars! is a science fiction wargame of revolt across the Solar System in the late 21st century. Earth’s colonies are rising up against an oppressive Terran Federation. The system is based on SPI’s Battlefleet Mars, but with additional forces and units representing several types of spaceships, ground units and special forces. Special weapons include artificial intelligence missiles, cybernetic attacks and enhancement of human warriors via nano-technology. Cards representing the various military-political-economic groups that are maneuvering for power are included. The map shows the Solar System out to Jupiter, with displays for each planet. Two maps, two counter sheets, two card decks.
