A lone space marine must battle an onslaught of demonic creatures in id Software's sci-fi follow-up to Wolfenstein 3D. Featuring an enhanced graphics engine that incorporates such details as light sourcing, texture-mapped floors and ceilings, and areas with variable heights, Doom features relentless combat across 27 levels. Use your fists or equip one of seven weapons, from a pistol and shotgun to a chainsaw and rocket launcher, to battle groups of imps, zombies, and other hell spawn. Ride elevators, throw switches, and collect keycards to advance, all while avoiding traps such as crushing ceilings and acid pools. Like Wolfenstein 3D, the action takes place from a first-person perspective, with your character's head displayed along with his health, ammo, and armor on the bottom of the screen. Up to four players can compete over LAN, while two players are supported via modem or serial link. ~ Scott Alan Marriott, All Game Guide
