Grand Theft Multiplayer is a free alternative multiplayer modification for Grand Theft Auto V, giving you the possibility to play with hundreds of players on dedicated servers with custom gamemodes built from the ground up and modified game experiences.
GT-MP hooks your GTA V installation when launching and reverts it back to its normal, clean state after being closed so you can seamlessly switch between GT-MP and GTA:Online without risking a ban!
Powerful Scripting Engine
Our powerful scripting engine provides you with all the possibilities to unleash your creativeness and create something truly unique.
We provide you with a powerful API. You can also use natives from the GTA 5 engine. Just take a look in our Wiki or the NativeDB.
GT-MP was created to be played with hundreds of people together at the same time! Our raised player limit will allow you to go beyond 30 players for immersive fun.
1. Download the GT-MP-Setup.exe from this mod page or the official website
2. Launch Grand Theft Multiplayer using the installed launcher
3. Press LAUNCH in the upper right corner to launch the game with the mod
4. Once in-game, you should see a menu in which you can use the server browser to join any server
5. After closing the game, the launcher will revert your GTA V folder to a clean state
Mod support & mods installation
We currently do not have active mods support inbuilt, which means servers won't be able to set mods to be shared with connecting clients.
But you are still able to install mods on your client, which ofcourse are only client side. This includes visual mods like Redux, Shader mods or vehicle replacements.
As our launcher ensures your game folder is in a clean state by copying mods and other stuff in a Disabled folder, you will have to install mods using the following methods.
1. Installing mods can be done using OpenIV to directly modify your game files.
2. If you rather wan't to use OpenIV's built in mods folder method, you can drop the OpenIV.asi in your GT-MP\bin folder.
3. OpenIV will then be loaded with your game on startup, you can drop mods you would like to run in your GTA V\mods folder like you are used to.
4. You can ofcourse install any *.asi mod you like by dropping it in the GT-MP\bin folder.
If you feel like hosting & developing your own GT-MP server, you can! Get the latest server binaries from our download page.
Check our wiki for more informations regarding GT-MP Scripting & Server hosting.
The reason we have a launcher is to verify that clients own a legit copy of GTA 5. GT-MP works like any other singleplayer mod and doesn't use / touch any of the GTA 5, Rockstar Online Services.
With the use of our mod you agree with our EULA.
Our Client is built on top of ScriptHookV like most of the singleplayer mods out there. All credits for ScriptHookV belong to Alexander Blade, more informations on the scripthook website.

Server & Client Patch
We worked hard the last months, to get this finally done. I really can't say more than just thanks to everybody that helped us.
A huge and special thanks to root which is a new developer working with me on GT-MP and to Neta & Hardy for the long nights we had while testing & developing this update.
For the future we are going to aim for smaller updates, which won't take as long as this one.
