My skinpack of real gangs and MOBs of Northern and Southern California (not by me) including Crips, Bloods, Surenos, Nortenos, Fresno Bulldogs, etc.
In addition to the usual gangs, there are gangs like Armenian Power 13, Pasadena Latin Kings 13, Grape Street Crips... There are several variations of Southeast and East Asian gangs, it's up to you to decide what you want.
There will be no gangs like Hustler Crips, Lime Hood Piru, etc. in the game. Nor will there be Polynesian gangs like Sons of Samoa, Tongan Crip Gang and Middle Eastern gangs like Fremont Afghan Gang.
Skins work great in single player and in SAMP. Installation: Replace with any skin, renaming it, put it in modloader.
