This game originated as a sequel to Wolfenstein 3D, going to be named Wolfenstein 3D Part 2. The team at Apogee quickly decided that it would be better as a stand alone game. They were right, ROTT is the furthest thing from Wolf3D! Its faster, bloodier, and has way more enhancements. It was one of the first FPS's (or only FPS) to incorporate Jump pads and I believe it was the first to incorporate a flight mode (powerup). Its the only FPS game to date where drugs are powerups!
