Named Game of the Year by over 50 publications, Valve's début title blends action and adventure with award-winning technology to create a frighteningly realistic world where players must think to survive. Also includes an exciting multiplayer mode that allows you to play against friends and enemies around the world.
Remake of the Doom 6666 game. Mostly accurate to the original. Made with GTK Radiant, Net Radiant and Hammer Editor.
The hell is DOOM 6666?
It's a freeware game with bad controls. It uses a lot of Half-Life sounds and graphics: Youtube.com
You can download the game from here, (it only supports 640x480 resolution): Caiman.us
Okay, so now we have that primitive-as-hell levels but with better textures and without annoying sounds. Not bad, but still disappointing.
