This is a first-person shooter in which players assume the role of a space marine who battles his way through Hell to save the Earth. Players use their fists, shotguns, machine guns, and chainsaws to kill an assortment of humans and monsters. Enemies explode into bloody chunks of flesh when killed. Enemy corpses remain on the ground, sometimes appearing as bloody piles of bones, blood, and viscera. Though the graphics are somewhat minimal (mid-90s renderings), several game levels depict pools of blood, mutilated bodies hanging from ceilings, with creatures' guts spilling out.
