Big maps/outside(outpost,memorial,docks,station,jungle)- sniper
Small maps/inside(archives,sewer,nightclub)- shotgun
Medium maps (Industrial,facility)- have a ciggie OR terralite
KDR is going up and up
Accuracy is going up and up
Final tip- I use a pistol on anyone camping/standing still and facing the other way. Weapons proficiency and XP baby.
