Space Siege

Space Siege is a science fiction RPG from Gas Powered Games, the same people who made the Dungeon Siege series. This time the threat is aliens from outer space and the focus is more on the character and story than on tons of hack and slash. As the character grows he will have the chance to replace parts of his body with mechanical improvements and to apply upgrades to the robot which accompanies him.
