A significant upgrade over the wildly popular Wolfenstein 3D, Doom is one of the most recognized and groundbreaking games ever created. An unnamed space marine serving on Mars must save humanity when teleportation experiments allow evil creatures to overrun Mars and its moons, Phobos and Deimos. The HUD looks a lot like the HUD from Wolfenstein 3D, but Doom adds a third dimension to the level design, allowing for ramps and stairs, as well as enemies that can attack from above or below. Another new feature of the engine is destroyable objects, such as canisters that can be shot and detonated to hurt nearby enemies. In addition to health, the player also has an armor meter. Originally a trilogy, a commercial release called Ultimate DOOM added a fourth episode. Shareware v1.25 was a special demo created for Sybex. Doom was so popular that Microsoft developed a Windows 95 port to showcase Windows 95 as a gaming platform. There are 4 episodes in this game, with only the first episode playable in the shareware version.

Episode 1 - Knee-deep in the Dead
Episode 2 - The Shores of Hell
Episode 3 - Inferno
Episode 4 - Thy Flesh Consumed
