D3 DemonWars is a Doom 3 cooperative multiplayer modification which takes place on earth in the year 2145 after the events on the UAC Mars Station. The marines and scientists that have survived the incident on Mars return back home just to face another nightmare, joining the remaining humans on earth for a final desperate fight against the hordes of hell...

D3 DemonWars is basically the Doom3 we always wanted to play from day 1 of its announcement. Having to fight cooperatively hordes of demons at huge outdoor facilities (Doom1+2) combined with the revolutionary unified light and shadowing engine (idtech4).

DemonWars is one of the very few multiplayer online shooters that provides absolute precise calculated damage and ballistics calculations. Every bullet fired in DemonWars is actually rendered as a single 3d bullet object that travels through the virtual space being affected by physical parameters such as gravity. Furthermore DemonWars makes use of Doom3's introduced per-poly-hit-detection-system which is superior in any thinkable way compared to the system used in common 3d shooters (hitboxes). DemonWars makes use of the "unified light and shadowing" concept to the fullest and renounces faking or skipping features.

DemonWars is a full FPS/3PS shooter combining the best of both worlds letting you play the game the way you want.

D3 Demonwars version (0.50) has the latest post processing effects added like Motion-Blur, DOF, FilmGrain (4 different steps), Edge Dimming and Bloom (4 different steps) to add even more current-gen eye candy to the game.

D3 DemonWars 0.50 is crossplatforming and fully compatible with Windows Vista, Windows XP, MacOS and Linux.

Additionally thanks to simulation, the upcoming Doom3 Demonwars patch (not to be expected to be released any time soon) will feature gameplay that will not only allow you to play with other humans cooperatively versus demons, but will also let you join the forces of hell as an undead trying to seal the fate of earth....

Awesome! I'm now working on a multiplayer mod myself, but for deathmatch. This mod was great, because coop mods are rare. LMS was great, surely you've played it :)

There are no servers! When I make a server, all the monsters just stand still until I attack them.

Nevermind, I figured out you had to join a team. Perhaps you can make levels like left 4 dead where you need to get from point A to point B against a huge horde of demons.

After seeing the Zombie I finally see the hope of it being possible....

In extremely far away versions would we see a possibility of playable Demons?

Being a Pinky or Hellknight..... that would be the best.
