i was stuck on this level before to comlete this get your warriors to attack the other gangs and if you see some spray paint hurry and grab it while the warriors attack the other gangs NOTE: if you see somebody spraying there logo and are about to win run and do the belly attack and start beating up the person until he is dead and keep grabing the spray and eventually you will win it worked for me hope it works for you or you could always use the complete current level cheat that really helps it also unlocks some gangs for you as well
