Multiplayer Co-op 0.9

Please consider donating to keep the master server up.

Ever dreamed of a cooperative mode in a grand theft auto game? Well, now it's a reality, sort of. You can complete missions with your friends, experience the joys of heisting with random people, or just drive around the interstate with your buddy.
You can share your game's NPCs by checking Share World With Players in the Settings submenu.
Enter as passenger by pressing G and talk in chat by pressing T

1. Install ScriptHookV & ScriptHookVDotNet v2.4
2. Drag & drop all the contents of the 'client' folder in the zip into your scripts/ folder located in the GTA5 root folder. If it doesn't exist, create one.
3. Once in-game, press F9 to open the menu, and connect to a server.
4. Note that if you are playing offline, you'll need to change your name in in GTACOOPSettings.xml found in your scripts/ folder.

Server hosting
You can host your own server too! Just extract all contents of the server/ folder anywhere you want and run GTAServer.exe. A Settings.xml file will be created where you will be change a number of options, like the server name, password, or whether announce yourself to the master server list.
Note that you need to port forward the specified UDP port.

Server Side Scripting
You can create filterscripts & gamemodes by referencing GTAServer and inheriting from ServerScript class. Then place your dll in the filterscripts or gamemodes folder, and add it to the Settings.xml file.
You can find additional server scripts at http://www.gtampco-op.cf/gtaco-op/forums/

Please post them here.

This has nothing to do with the Online mode, so you will not get banned.

    @JoelPlayz fivereborn is not opensource which means its developers are greedy scum and if it ever gets popular r* will just put them in jail and nobody ever would be able to continue the work, just like it happened with v:mp.

    Guys if you want to switch it from F9 in the Config.ini, where it says F9, just switch it to your desired key whether it be U or F12. Just saying incase you have another menu that opens with F9 ^_^ Hope this helps!

    Surprised not to see your "building something better than Coop" Project yet Guad. I waited patiently. Have you forgotten us. Don't leave your wonderful mod behind. So many enjoy it!

    Server says update client. use Client 0.9.2 or older
    No Servers/F9 Not Working? Restart GTAV
    Password blocked. Pick a different server.
    Or always F9 > Server IP > > Connect
    Or join us at the same IP on IVMP or MTA

    This may be a bit of a dumb question, but if I'm doing an LSPDFR patrol with a friend of mine and we have different cars installed, or different callouts or whatever, how will that affect the server? I've had the mod downloaded for some time, I've just never tried it for fear it would break my game or something, lol. If anybody could get back to me, I'd be very appreciative! :)

    @Dragos1213 What if a callout spawns that only one person has? Would the other have to just kinda follow along?
