There are many gangs all across America, but the most powerful ones are listed here:
The Ronin: A grouping of disciplined, fearsome warriors who favor stealth, subtlety, and honor. Highly traditional in their philosophies, they see themselves as "dishonored" by modern society for whatever reason, and seek to find honor and retribution in slaying their foes and dying well.
The Luchadores : A clan of steroid junkies that wear mexican wrestling costumes and tend to favor over-sized high power weaponry. The luchadores are very aggressive, and they are obsessed with strength. Their leader is the brutal Eddie "Killbane" Pryor.
The Clowns: A deranged gang of masked men who all wear clown-like masks or facepaint. The Clown Gang members are typically psychopaths with dangerous mental issues, and they all are murderers. They always carve smiles into the faces of their victims. Their leader is the maniacal psychopath The Joker.
