1992: Wolfenstein 3D
While not considered a "zombie game," id Software's Wolfenstein 3D
introduces players to a memorable zombified enemy, the undead guard. Created by Dr. Schabbs, these Frankenstein's monster lookalikes have a gun surgically grafted into their chest. A year after Wolfenstein 3D's release, id's Doom
shows off a similar enemy, the zombieman, which is the weakest enemy in the game.
