Doom (1993 video game)
Doom (1993) is a first-person shooter for MS-DOS and Windows developed by id Software. It uses a 2.5D engine: environments render in 3D perspective but movement is confined to a 2D plane, and enemies are 2D sprites using billboarding. Players assume the role of a space marine fighting demons and possessed undead humans across labyrinthine levels grouped into episodes, each ending in a boss fight. Completion requires reaching a marked exit room while managing limited ammo, health, and armor—and avoiding hazards like toxic waste and crushing ceilings. Five difficulty levels scale enemy count, damage, speed, and aggression. The game supports cooperative and deathmatch multiplayer over local networks and modding via WAD files. Its design prioritises fast-paced action over narrative, with minimal plot conveyed through inter-episode text.
