You're planning to go to a Baller funeral and shoot everyone there. Your crew is getting pretty large. Use the R1 to target, then the up D-pad to get them to join your gang. You should be able to have at LEAST two guys by now - if not, do other missions and make sure you're wearing lots of green things.

Drive all the way out to the spot with a timer running. You all hop the fence. Hop the fence.

You have to stay near your group and use up and down to get the guys to either take up positions or follow you. Just have them follow you, and keep shooting. Your main target is of course the one furthest away, but shoot everyone. When they're all dead. Sweet is the blue mark at the far end of the cemetery. Go to him with your two guys, and get into the car with him.

Now you have to drive home - if you know where the stars are by now, it's pretty easy.

Mission passed!
