From there on he must prevent a Nazi plot to create an army of undead mutants before attempting eliminate Adolf Hitler himself. In the opening episode he finds himself in captivity and must escape Castle Wolfenstein. The plot of the game focuses on William 'BJ' Blazkowicz, an American spy, as he single-handedly takes on the Third Reich. However due to the novelty of the new 3D engine they felt it would be necessary to make a simpler, faster paced game, and so Wolfenstein 3D was born. Having developed a new 3D engine, they opted to remake the 1984 game Castle Wolfenstein. The developers behind the game were id Software, led by programmers John Romero and John Carmack. The full game was then released weeks later, going on to become both a critical and commercial success (selling over 200,000 copies by 1993). The first episode of the “grandfather of 3D shooters” was released in 1992 by shareware publisher Apogee Software. While Doom is often thought of as the game that kick-started the popularity of the first-person-shooter genre, that honour belongs to Wolfenstein 3D.
