From Multi Theft Auto: Wiki
Multi Theft Auto wiki. On this wiki you'll find a wealth of information on using Multi Theft Auto.
There are many things you can do to help us improve MTA - create a map, a gamemode, help document scripting functions, write example code, write tutorials or just play MTA and report the bugs you find.
If you have any questions or problems related to scripting, feel free to get in touch with us on our IRC Channel.
