The story: The year 2345, the world is ruled by corporations welthy enough to buy entire countries. One corporation wanted to more. It wanted the world. To do so it engineered 2 super soldiers to do its bidding. Over the course of time an underground resistance managed to capture one of these super soldiers and manage to give him back his humanity. Thus our hero the neo spartan was born. His mission would be to take down his own brother CRUSHER and then the corporation he belonged to.
