## What it is
Multi Theft Auto is an open-source multiplayer modification that adds networked multiplayer gameplay to Grand Theft Auto: San Andreas via code injection and hooking. It functions as an extensible game engine exposing the original game's functionality through Lua scripting, allowing servers to run custom game modes for hundreds of players.

## Use cases
- play gta san andreas online with friends
- host a multiplayer gta san andreas server
- create custom game modes with lua scripting

- build custom maps and race tracks for multiplayer gta
- mod grand theft auto san andreas for network play

- you want an open-source, actively maintained GTA multiplayer mod
