Yet another great Doom 3 mod is Last Man Standing Coop
. To quote,
Last Man Standing Coop Mod is a Doom 3 Single Player and Multiplayer cooperative modification that aims to bring back the feel of the classic Dooms. Our LMS Mod gametype is survival in nature where you face swarms of attacking monsters to the adrenaline pumping energy of heavy metal soundtracks. We also fully support Cooperative play in the Single Player levels through the SP Coop gametype and the Doom 3 expansion pack ROE through the gametype ROE Coop. Also the Classic Doom for Doom 3 Mod has been integrated into LMS 3.0 to provide cooperative support!
You can see their website here
for more info, and even download
version 3.0 of the mod - at a price tag of around 301mb, it features "SP Coop, ROE Coop and Classic Doom for Doom 3 Coop and of course LMS Mod with over 20 intense custom maps!".
The LMS Coop mod is also taking place on ModDB's Mod of the Year Awards
