As the heavily-armed humanoid, you blast, battle, bound and blunder your way over more than a hundred screens of blood-curdling action. Release a deadly grenade to devastate a birth pod and shoot the hordes of aliens that slither and scramble to overwhelm you. Rocket a gun emplacement and pneumatic hammers hurl you end over end back across the screen. And in a new twist, some of the screens can be played as a vulnerable but athletic Vitorc or as Exolon, a lumbering but powerful exoskeleton.
