The game was launched as part of a Kickstarter by Green Ronin Publishing. Less than 24 hours later, it had well surpassed its goal of $US30,000, reaching over $US194,000. Built around the Adventure Game Engine rules used by Green Ronin's other tabletop games, the RPG tasks players with putting themselves into the simmering conflict between Earth, Mars and the Belt, taking on a variety of roles, from combat operatives to diplomats and venturing out into the stars.
