FiveM developers have created a multiplayer modification for Grand Theft Auto V which allows gamers to play online on dedicated servers.
The client is in early stages, but is "built on the solid multiplayer framework set by Rockstar Studios themselves as part of the RAGE engine, which has gone through rigorous testing since its first release in 2008, adding high-level customizability features." says the description which accompanies the preview video for the new GTA V multiplayer client.
Playing on the FiveM dedicated server will allow gamers to play using mods and also play modded multiplayer modes. The video above is from an early build and does not reflect the quality of the final build. FiveM intends to add a browser feature in a later build which will allow users to select servers with certain filters, custom rules, game modes etc.
If you wish to check the servers out for yourself, you can download them directly from GTAUniverse.
