From the back of the box:
On the raw rock that was once Earth, the remnants of Man cling desperately, huddling beneath the energy dome which shields them from the poisoned environment.
Into this superstitious, barbaric world strides Doc the Destroyer. Outcast and heretic, he must survive the horrors of the fetid underworld and the gladiatorial arena, to confront the tribal elders and save the Dome dwellers from extinction.
His quest is an ingenious fusion of strategy, adventure and arcade combat. Featuring the ability to alter Doc's characteristics at the start of each game, it also offers an extensive mappable landscape, menu-driven multiple options, and some of the biggest fighting sprites ever seen.
