In 1992, id Software released what is widely believed to be the original first-person shooter, Wolfenstein 3D. In contrast to the Muse Software games, the id Software title preferred high-speed gunfights to the stealthy approach. Nine years later, Wolfenstein entered the hardware accelerated realm with Gray Matter’s Return to Castle Wolfenstein, then powered by id Tech 3, also known as the Quake III engine. That game was followed two years later by the free and monstrously popular Wolfenstein: Enemy Territory. Finally, on August 18th of 2009, Raven Software and id Software released to North America Wolfenstein.
