Doom

First person shooter fans have had intimidate dealings with Hell ever since id Software released Doom in 1993. The original casts players as an unnamed and tough-as-nails space marine charged with saving humanity (what's left of it, anyway) from armies of demons that poured through a gateway between Mars' two moons, Phobos and Deimos. Eventually, gamers transition from the corrupted space station to Hell itself, complete with walls made of human faces and pentagrams.
