Multi Theft Auto is a multiplayer modification (mod) for the Grand Theft Auto game. The mod adapts the game in such a way, you can play Grand Theft Auto with your friends online and develop your own game-modes.
Multi Theft Auto: San Andreas provides multiplayer functionality in the game, and gives a completely new platform on-top of the original game, allowing you to play all sorts and types of game-modes anywhere you want.
The scripting engine used is very powerful, and the MTA Community System features a Resource center, which allows you to upload and share your developed resources with other members of the community.
