The Fastest Way to Make Money and RP
Currently there is a method for players to farm Jobs repeatedly. To do so:
Hit "Like" on an online Mission after completing it
Have everyone in the game hit RT (360) or R2 (PS3).
The word "Restart" will appear in the final column and shortly after, the Mission will begin again. Players will be able to do this infinitely, getting money and RP each time.
This works best on high-yield Jobs that can be repeated quickly, such as Violent Duct. Remember that if you exit the Mission entirely, it is possible that you will be locked out of it for a duration of time, preventing you from restarting it.
