Multi Theft Auto
“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.”
Klingt gut. Hat das schon mal jemand von euch angetestet?
