It's one hundred years in the future and the now-benevolent organization known as A.I.M. has been fighting a non-violent conflict with the fascist government it wishes to change. But there's a splinter group that's ready to return to its violent roots with Death's Head 3.0. Problem is, the killer robot isn't sure what side it wants to be on.
