I'm not sure if this has been asked before but.

Does anyone know of any Doom3 coop mod project web pages (and this means none of the cd-key stealing disguised ports) ? I'd just like to know of one thats been in progress so far and have additional info on it.

there may be some mods that plan to include Coop, if thats what you mean. i don't know any of them off the back of my hand. if you mean a mod to Coop through Doom 3, then i don't think there are any mods of that sort. the coop-mod-that-wasn't kinda scared everybody off of the idea.

Damn. I hope someone has the stuff to eventually put together a Doom3 coop mod cause then I'm sure the game will get more attention from the multiplayer coop community. :)

There used to be a mod called doom 3 co-op at doom3maps.de but I guess it no longer exists.
Sorry the doomer

From what I've ehard the co-op mods steal your CD keys. I'm waiting for RoE.
