replaying missions like a drone.
As far as I can tell, most of the exploits have been a result of playing the same missions again and again. Early, easy missions.
Odd, I could have sworn I made around 2 million every 2-3 minutes using the adder glitch in LSC.
There we go. Rather than replaying missions like a drone, you exploited a glitch like a drone. Still makes you a drone. And a pathetic cheat.
