The San Andreas, Liberty City, Vice City, Manhunt I/II, and Bullworth maps combined in one big map. Not only that, the mod also adds gang wars, added (not replaced) vehicles, peds, and weapons (yes, you can modify added vehicles and buy added weapons in weapon stores) in the same style as if R* were to make an expansion for GTA: San Andreas. Read our detailed description to find out how each city is populated with the gang turfs, vehicles, peds, and where weapons can be obtained! Simply put, everything is GTA:SA-styled. Furthermore, the mod also comes with an adaptation of the San Andreas Multiplayer mod which allows multiplayer gameplay while also allowing server developers to migrate easily (SA-MP gamemodes/filterscripts will still work!)
