Doom

DOOM (DOOM 1) is the genre‑defining landmark first‑person‑shooter developed by id Software, released for MS‑DOS in December 1993. Widely regarded as the foundation of modern FPS gaming, you control the iconic unnamed space marine “Doomguy”. After a catastrophic teleport experiment opens a portal to Hell at UAC research facilities on Mars moons, demonic hordes overrun the base. As the sole survivor, you blast through infested military outposts and hellish realms to stop the demonic invasion. Powered by the revolutionary id Tech 1 (Doom engine), it delivered 2.5D texture‑mapped environments with height variation, dynamic lighting and built‑in automap. It features an iconic arsenal including pistol, shotgun, chainsaw and rocket launcher across three core episodes. Distributed via shareware with the first episode free to public, DOOM pioneered LAN multiplayer deathmatch and co‑op gameplay, and fostered a massive modding community for custom WAD levels. The expanded retail version Ultimate DOOM added an extra campaign episode. With fast‑paced brutal combat, heavy‑metal soundtrack and dark hell‑themed visuals, Doom 1 DOS remains one of the most legendary vintage PC games of the 1990s.

These games get the keyboard directly — the controls are whatever the game itself defines, usually in its own help or options screen. Gamepads are detected automatically. On phones you get on-screen buttons.
