1.This thing is RUN. RUN after each kill,RUN to be behind the enemys ,RUN through the map all the time.DONT STOP.DONT CAMP(cheytac is exception(and ofc its not a problem to fastcope without camping))
2.Decent weapon:u need to use smtg like m4\ak(dont like it)\g36c(my choise).(DONT USE ♥♥♥♥♥♥ mp7\saw and etc) IF u played mw2 or any other cod with a fastscope - take cheytac ( need to be sure that ur not a noob;))
3.Dont use any sights on your weapons ( your screen is shaking with them and it becomes harded to kill).
4.Perks(psionics)are useless.Dont waste money.
5.Dont be sure that pistol will help u(almost always u will be killed coz pistols useless(use it rare!))Better just reload your weapon.
P.S. REMINGTON OP
