As Captain Carnage or Major Mayhem, it is up to you or you and a friend (in simultaneous action) to rescue the hostages while shooting hundreds of mutants bent on your destruction. As you walk and run forward, backward, left, right, and diagonally through 20 battlezones of nonstop action, you'll always have your machine gun by your side. Additional weapons which you can find along the way include grenade launchers, rocket launchers, plasma machine guns, flame throwers, spray-fire rifles, defensive blades, and an assortment of bombs.
