If you are tired you can not play call of duty black ops zombie mode then do not fret, here I bring a mod that turns doom 3 to zombie mode made by me, especially for doom players.
A demo map for this great mod, zombie forest, only available 4 rounds and his first boss.
Extract the two files to Doom3/zombie_mode, and launch the mod and write in the console 'map nazi_zombie_forest and enjoy the demo map!
*New script pistol (from italian version)
*New ambient sounds
