Taking Doom³ PVE (Coop) and PVP (Deathmatch) multiplayer combat to the next level and beyond...

D3 MCS: Mars City Security is a Doom3 Modification that puts heavy emphasis on cooperative and adversarial multiplayer, merging the fast and addictive gameplay of the predecessors (Doom1 & Doom2) with the enhanced Doom3 technology (optimized netcode for Online Internet & LAN networked multiplayer with improved idtech4 unified rendering).

The “Campaign” PVE (Coop) gametype lets players play through default & custom created campaign missions with other players cooperatively. Experience community made custom maps with your friends that tell stories never before experienced in the Doom³ universe.

The “DemonWars” PVE (Coop) gametype throws players right into the epic battle that broke out throughout the entire solar system after hell has been unleashed. Fight as a human with other players cooperatively against the hordes of hell trying to make a last stand for mankind.

The PVP (Deathmatch) gametype lets players fight it out adversarially on a variety of arenas for the ultimate player versus player domination in “team” and “free for all” PVP multiplayer.

IMPORTANT NOTICE !!!

In case the DOOM3 MasterServer happens to go offline you can still browse for online Doom3 and MCS servers at the following link: Gametracker.com

Fellow MCS fans,

we would like to thank everyone for the amazing online PVE & PVP matches during and after the release of MCS version 1.2.1.8, helping us stress-test this build worldwide in all its glory.

All that positive feedback from community members and new players alike, confirmed our dedication in having spent all the time and resources to bring MCS to its current state.

Special thanks go out to the modDB staff members, who were always very supportive throughout the development and "man!" were we positively surprised to win the editors choice award for the best multiplayer Mod 2015. That truly was the icing on the cake after the public release !

Big thanks also go out to the reviewers here on moddb.com giving MCS such positive review-scores.

In the meantime here an almost 1 hour long "post-public-release-recap" video, summing up the various MCS trailers and online matches played together online with MCS players worldwide during and after the public release.

Great mod! Thanks to the creators for all the hard work!
I have a problem with DemonWars: the game always crushes without any error after 1min of playing. I play singleplayer with AI ally. Specs are: Doom3 retail 1.31 putched, Win7pro SP1, Core i5 2500k, 8Gb, GTX 560 1Gb.
Co-op is fine though.
PS: it'd be very great if we have DB-shotgun in this mod. :)

What you could try instead is to play as a client connected to your own local dedicated server.

Let me know if playing it that way is still causing crashes for you.

Ok, I figured that out. Timelimit=0 was causing the problem. I set it to 99 and all works fine now.
PS: same thing happened with dedicated server. It crashed after I voted for infinite timelimit.

I'm definetly looking foward to play this mod. You guys at MCS team did an amazing job, to bring this mod to life, and I love every bit of it. The only thing for me that would make IMO, this mod perfect if it also had a L4D style gameplay mode that would make monsters playable In multiplayer. A game mode like this would be epic, I always wanted to be the Baron of hell / Coco Demon / Revenent, / Archvile.... Killing marines would be just as fun as killing monsters... I really hope this subject has been taken into consideration. Regardless, This is one Awesome mod!!!!

1. No this mod does NOT work with the BFG edition.
2. I can't comment on piracy topics.
3. About 75% of the stock campaign is playable in coop plus about 3 hours of an additional high quality custom campaign story that is playable completely in coop.

Fantastic and fun multiplayer mod with coop and all normal multiplayer modes, on a game that add almost no multiplayer at all, and a very basic net code, is to prove that talent is the more important aspect on the quality of a game/mod not the game or engine where you make it.
