One of the most infuriating tasks to be added into the game, setup from skier comes after chumming and requires you to kill 15 PMC’s in Customs while wearing specific gear and using 12 gauge shotguns. The specific gear required is the ushanka ear flap hat and the scav vest. Coupling this quest with another, silent caliber, we can get alot done alot faster by using suppressed shotguns with the salvo or hexagon suppressors. The faster you get to this quest in a wipe the better, so you can take advantage of the lower levelled players going to customs with lesser gear for early game questing.
