At Rank 75 you’ll unlock a mission called Rooftop Rumble from a guy named Martin Madrazo (he leads a Mexican narcotic gang in the Los Santos area). What you need to do is basically kill 5 people and it’s done, and the video clip below will show you how to complete it in the most efficient way possible. Using the method shown in the vid it’s possible to earn up to $2 million and 400K RP per hour. You can also do it if you are a lower level and get invited by someone of course. Just use sticky bombs instead of the grenade launcher and kill any survivors with a rifle. https://www.youtube.com/watch?v=28aESgAX5EA
