"In the 22nd Century the darkest region of space lies in the hearts of men." The fate of all humanity rests with a small clutch of brave soldiers, and their sophisticated intra-stellar fighting machines, as they must defend the free solar system from a sinister invading force, in order to fight... for their future. But when allies become enemies and enemies become allies, battle-lines and allegiances are blurred as humanity races to save itself... from its own utter destruction.
