Before Wolfenstein 3D, there was Catacomb 3-D. Developed by id Software in 1991, this first-person dungeon crawler is the direct ancestor of the FPS genre — the first game where you could see your own hand on screen, and the prototype that proved the engine that would change gaming forever.
About Catacomb 3-D

Catacomb 3-D was developed by id Software (John Carmack, John Romero, and Adrian Carmack) and published by Softdisk in November 1991. You play Petton Everhail, a wizard who must descend into catacombs to rescue his friend Nemesis from the demon Morbidity. The game was released as freeware by Flat Rock Software in 2009.
This is the game where Carmack first demonstrated that smooth texture-free 3D rendering was possible on consumer PC hardware — the technical leap that made Wolfenstein 3D and Doom possible.
Gameplay
Catacomb 3-D is a first-person shooter played from a first-person perspective. Your wizard attacks enemies by casting magic bolts — there are no guns. The catacombs are filled with skeletons, demons, and other monsters across 30 levels of increasingly complex dungeon navigation. You search for keys, find potions, and push through waves of enemies toward the boss.
Why It’s Worth Playing
Playing Catacomb 3-D is like reading the first draft of one of gaming’s greatest works. The engine is recognizably the ancestor of Wolfenstein 3D, but the fantasy setting gives it its own identity. For anyone interested in FPS history, this is essential — the moment the genre was born.
