Now you're on the Countryside, but one of your friends take the Enforcer to you and tell that Madd Dogg's Crib is ocuped with Mountain Cloud Boys inside. You go there and kill them and exit the mansion. You actually found your Sniper Rifle and Los Santos Vagos rioting and attacking you with Molotovs and MP5. Then, a car from the Vagos pursuit you on foot and you found Ballas rioting. You will have to kill all those gang members.
