OpenCoop is a cooperative multiplayer modification for Doom³.

Up to 4 Players can fight over Lan or Internet the Id Software campaing, the Addon "Ressurection Of Evil" or one of 42 custommaps as InHell or ClassicDoom for example.

You can customise you playermodel with 13 individual heads and tint your amor over a colorslider.

Every player can pick up weapons and armor once. Collected health from medpacks or heathstations goes into a heathpool, where you take HP from when respawning after dying.

The AI got tweaked to act smarter with multiply attackers and the strength scales depending on the number of players.

In "Hellwave" gametype you fight against waves of monsters on the original DM maps or on one of 3 new custommaps.

The work on maps go on and there is a new oc_custom coming up.
Thats "Tested6.0". A first betaversion with everything ported but still without spawnprogress will be released soon.

So its again on you to report traps and bugs.

Another cool thing i was working on is animating the spidermastermind that D³ mod "Recall to Hell" build and released as free content.

Model and textutes by RtH, rig and animation by klonsemann.

Till now the following animations are done, walk_forward (pic above), srafe_left, idle.

There is no concept about attacks and behavior jet.
So thats more a personal test than a preview to a release.
If this ever gets completed ingame, maps must be found where this enemy could play out its strength.

I've completed the normal campaign with a friend using Open Coop, but I don't understand how to make it work for Resurrection of Evil? Any help you can give?

Is this a finished product and if so is it compatible with BFG edition?

Why would you want it for BFG edition anyway? I thought BFG edition butchered the original Doom 3.

they were trying to get more players into DOOM 3, by making it easy, the game is now forgiving with ammo, and enemies don't do that much damage, also the flash light is mounted on your shoulder now so you can shoot and use it in the same time, it has a battery though

Doom 3 OpenCoop is an excellent campaign coop mod, although largely unfinished and probably abandoned now - it still gives you a good time with your pals if you're too scared to play the campaign on single player (like me).

While the Resurrection of Evil expansion pack was recently just supported, it is still quite buggy (as the Artifact does not work) requiring you to cheat or use some exploits to pass through some of the puzzles.

OpenCoop Alpha 2.0 has still some unfixed issues and bugs but the new features like customizable heads and customizable player armour colour. When starting a server, it still gives you the message that you are playing OpenCoop Alpha 1.1 which can be bothering sometimes and might cause confusion but still it works great.

The player limit of four (4) players only is still present, even when trying to play with Resurrection of Evil loaded as it supports eight (8) players on multiplayer but I believe can be fixed through a server command (which only the server administrator can enter) si_MaxPlayers <amount of players>.

Over the years, the popularity of the mod has beginning to decline overtime as newer games take over the market and Doom 3 was forgotten by some - but not all.

If you want to play OpenCoop with a friend or two or three - get the non-Steam version of Doom 3 (the Steam version doesn't work nor the BFG Edition as it doesn't support modifications) then get LogMeIn Hamachi (unless your router supports port forwarding so you can play without a VPN software).

Not sure if you need an original and working CD key though because we haven't tried to play together yet but I'll edit this comment in the future once we do.

Have fun! (also d3opencoop.com no longer works so I don't know how we can get updates anymore D:)

si_MaxPlayers won't work :( , the project is certainly discontinued, LMS 4 is just the same :( however the campaigns work alright there .
