Multi Theft Auto (MTA) is an open-source software project that adds full on-line gaming support to Rockstar North's Grand Theft Auto: San Andreas PC game, in which this functionality is not originally found. It is the first open-source modification that adds a highly customizable network play element to a commercial closed-source single-player PC game. Developed as an experimental piece of software for earlier Grand Theft Auto series, Multi Theft Auto has become an advanced multiplayer platform for gamers and developers. Our software provides on-line gaming for dozens of players running user-generated gameplay content and scripts through a Lua virtual machine, and is freely distributed under the GPLv3 license.
Twelfth stable release of the Multi Theft Auto: San Andreas multiplayer modification for GTA: San Andreas, with several new features including voice chat, custom handling, special skins and more! This installer package consists of a game client, dedicated server for Windows and a resources package, which includes map editor and a race gamemode, along with several other gamemodes, maps and utility scripts.
This patch has many new improvements, including NVIDIA Optimus support and new Anticheat features. Here's the patchnotes below.
