The Wolf3D Engine is a raycaster engine developed by John Carmack for the hit FPS game Wolfenstein 3-D. It features smooth scrolling with textured walls, variable screen-size, and sprites. Maps are tile-based.
Being 12 when this was released it took all night to download the shareware demo, a huge 1 meg sized file. Well worth the wait and getting a soundblaster card and stereo system, needless to say it was pretty sweet to feel the chain gun fire with the sound cranked up making it that much more of an experience in a game than ever. Good stuff.
