A seminal first-person shooter where players take the role of a lone space marine ("Doomguy") fighting through hordes of demonic invaders unleashed from Hell on the moons of Mars.

Relentless combat, quick reflexes, and constant movement are core to the gameplay.
Features grotesque demon enemies (Imps, Barons of Hell, Cacodemons, etc.), hellish environments, dark lighting, and a constant sense of dread and isolation.
Set on futuristic Martian moons (Phobos & Deimos) and UAC (Union Aerospace Corporation) facilities.
Emphasizes high scores, secret hunting, and fast, skill-based play.
