While playing a game, press Down, X, Up, Black(2), Up, Right(2), Up. A note will confirm that you entered the code correctly. Lock on to someone (any pedestrian or even rival gang members) and press Up on the D-pad to recruit them. They can do everything that your Grove Street Family members can do. Each person you recruit will get a 9mm unless they already have a gun. Repeat this code to disable its effect.
