A lone space marine must battle an onslaught of demonic creatures in id Software's sci-fi follow-up to Wolfenstein 3D. 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. Doom for Xbox Live Arcade supports four-player deathmatches and two-player cooperative gaming, either through Xbox Live or via split-screen on the same system. ~ Scott Alan Marriott, All Game Guide
