Which GTA Games Grand Theft Auto Connected Supports and What It Adds

Grand Theft Auto Connected (gtaconnected.com) is a custom scriptable multiplayer modification for GTA III, Vice City, San Andreas, and GTA IV. It adds synchronized multiplayer with peds, traffic, and missions, scripting in JavaScript, Lua, and Squirrel, custom objects, dynamic snow, and a module SDK for both server and client. It works alongside the single-player games rather than replacing them: the site states you can "play both offline and online."

Supported games

The modification is a separate multiplayer layer for these titles. It is not affiliated with Rockstar Games, as the site notes.

What features it adds

Multiplayer and synchronization

• Synced peds, traffic, and missions — non-player characters, vehicles, and mission logic stay consistent across players.
• Peer-to-peer sync — players synchronize directly rather than relying solely on a central server model.
• Offline and online play — the same installation supports both single-player and connected sessions.

Scripting and customization

• Scripting in JavaScript, Lua, and Squirrel — server and client logic can be written in any of these three languages, which lowers the barrier for modders already familiar with one of them.
• Module SDK for server and client — lets developers extend the modification with compiled modules beyond what scripting alone allows.
• Custom objects — servers can add objects beyond the base game's assets.

World and environment

• Dynamically growing and melting snow — a weather feature that changes over time rather than a static toggle.

Platform support

• Windows XP and WINE — the modification is documented as running on older Windows versions and on Linux through WINE.

How to decide if it fits your use case

• If you want multiplayer for GTA III, Vice City, San Andreas, or GTA IV, this is the scope of titles it covers; games outside that list are not supported.
• If you plan to write custom game modes, the three-language scripting support and the module SDK are the relevant capabilities to evaluate.
• If you run Linux or older hardware, the stated WINE and Windows XP support is worth checking against your setup before installing.

Downloads, version history, a wiki, a forum, and a Discord are listed on the site as the places to get the software and find setup help. The site also links a Patreon and a hosting page; the available page content does not state pricing or whether an account is required, so confirm those details on the site itself before relying on them.
