The man, the myth, the legend: John Carmack. He's considered the greatest programmer of his type in the entire world, and he's stunned the gaming community numerous times with each new 3D engine he's created. We had an opportunity to talk to Carmack about the "good old days" five years ago when he and id Software were in full Doom swing. What does he think of the Doom engine now? What does he think of Doom now? Where did the name "Doom" come from? It's all right here!

This is a copy of the source code for DOOM's executable, v1.10 (public release version). This source code was initially released under the DOOM license in 1997, but then dual licensed (DOOM/GPL) in 1997 to encourage transparency in the development of ports and extensions of the DOOM game engines. A copy of the source under the DOOM license may be obtained at id Software's FTP, or at one of its mirrors on /idgames in the /idstuff/source directory.
