The game is set on Mars, a century after a great upheaval. Powerful guilds battle over water, which has become a valuable resource. Two of the most powerful of these are Aurora and Abundance. The player takes on the role of Roy Temperance, an escaped prisoner of war who finds himself caught between a variety of powerful factions, and must also battle a variety of creatures created by the planet's radioactive environment.
