You're a marine, one of Earth's toughest, hardened in combat and trained for action. Go to Hell and back in DOOM, as you battle through many levels of infernal action. Use pistols, chainsaws, shotguns, chain guns, rocket launchers, plasma rifles, and the BFG-9000 to blast demons, mutant spiders, possessed marines, and other creatures from another dimension. Take a trip to the moons of Mars and keep the demons from taking over!
