Multi Theft Auto is how you play multiplayer Grand Theft Auto on your computer. It looks pretty sweet and I remember trying it when it first came out a few years ago.

Well, now you can follow its development at GitHub: http://github.com/multitheftauto/multitheftauto

Apparently it supports Lua for creating gameplay content and has a really nice wiki, among other cool features.

Welcome!
