The demons came and the marines died. Except one. Your are the last defence against these hell-spawned hordes. Prepare for the most intense mutant-laden, blood-splattered action ever! The texture-mapped virtual world is so real, you don't just play DOOM - you live it.
This is the Doom Developer's Kit (Vol 1.) from Diamond Data in Denmark, This CD has editors for making the sounds, textures, levels, graphics and more for Doom, Doom II, and Heretic, A large amount of wads for Doom, Doom II and Heretic, and some goodies, This file is from Archive.org and I do not take credit for it, nor do I own anything on this CD either.
To run Doom or Doom II wads you must have a sourceport such as GZDoom or ZDoom, Or you need the Doom Collectors Edition Launcher to activate wads.
