Wolfenstein 3D was a critical and commercial success and is considered one of the greatest video games ever made. An additional episode, Spear of Destiny, was released as a stand-alone retail title through FormGen. The game was released through Apogee in two sets of three episodes under the shareware model, in which the first episode is released for free to drive interest in paying for the rest.

Wolfenstein 3D features artwork by Adrian Carmack and sound effects and music by Bobby Prince. He and designer Tom Hall designed the game, built on Carmack's engine, to be fast and violent, unlike other computer games on the market at the time. After a design session prompted the company to shift from the family-friendly Keen to a more violent theme, programmer John Romero suggested remaking the 1981 stealth shooter Castle Wolfenstein as a fast-paced action game. In mid-1991, programmer John Carmack experimented with making a fast 3D game engine by restricting the gameplay and viewpoint to a single plane, producing Hovertank 3D and Catacomb 3-D as prototypes.

Wolfenstein 3D was the second major independent release by id Software, after the Commander Keen series of episodes.
