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, improved idtech4 unified rendering).

The "Campaign" PVE (Coop) gametype lets players play through default & custom created campaign missions with up to 4 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 up to 4 players cooperatively against the hordes of hell trying to make a last stand for mankind.

The PVP (Deathmatch) gametypes let up to 8 players fight it out on a variety of arenas for the ultimate player versus player domination in "team" and "free for all" adversarial multiplayer.

Mars City Security:

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

Credits to the amazing Doom3 Community members that make MCS possible

-==August 2015 Update==-

Hello fellow Doom3 fans,

this update is for the diehard oldschoolers among you that still vividly remember the feeling of playing the original E1M1 Doom1 level on their 386ers cooperatively across the Local Area Network for the first time, seeing their buddy's Doom Marine Player Character suddenly appear on screen, effectively sharing the same virtual world across multiple PCs...

Taking krankymonkee's excellent DHC Hangar recreation and adding some custom codebase finetuning love to it, allows me now finally to present you a fully co-op multiplayer compatible and visually pimped version of E1M1 for D3 MCS...

This custom campaign level will be playable with up to 4 players cooperatively with all bells and whistles down to the atmosphere depressurizing should a stray bullet hit any of the isolating windows...


"Sigh", this really brings back memories... ;)

Maybe you should give the default weapons secondary functions instead of ironsights.

Man, two things.

1-. Bots can be use multiple skins?, example: DOOMROE marine skin, Bravo team marine skins, others...

2-. Extreme death can be posible?, you know like clasic doom.

1. Currently there are friendly Security AIs implemented that support human players. On a later release update, full multiplayer bot support is planned. Those multiplayer bots can have many different player models just like the human playable characters and are able to participate in Deathmatch, Team Deathmatch and CTF gametypes...

2. I have no idea what "Extreme Death" is, sorry...

Extreme Death happens in the classical doom (for example) when you get telefragged or when you have very low HP and you catch a rocket to the face.

Actually Yes, A CTF mode is planned for a later release update for MCS. And Yes currently there is a new weapon already implemented (the Railgun) and other new weapons might follow.
