Just like in real life, the gang structure has been changed to match where the gangs should actually be, unlike the stunt Rockstar pulled with placing them in the wrong neighborhoods.
Rancho's neighborhoods have been replaced with African Americans throughout the area, removing the occasional gangsters along with the rest of the Hispanic population
Rancho projects were repainted and replaced with Families (now Bloods)
Vagos moved to East LS (El Burro Heights) instead of Marabunta Grande (Mara Salvatrucha are no longer active in real life in California, unlike Sureno sets who are still alive and kicking in East LA)
New Ped has been added to the gang (Debo)
To install, start by running OpenIV and enabling "Edit Mode", then proceed to place each file in its directory from the "bloodshit" folder.
The authorship belongs to the original creators, this is simply an homage and remake of an old mod.
