if your using a BR shoot 4 or 3 shots into the body then 1 more into the head, thats a 5 or 4 shot kill. also, ALWAYS LOOK AT YOUR RADAR!!! and camping doesnt mean your a noob, means your smart, so you might want to give that a chance. and use grenades to your advantage, you can throw a grenade and right after it explodes head shot your opponent for a 1 shot kill, or light him up with an AR. dont stand still when you shoot, or just run closer, do lots of jumps, and move side to side, or move in a circle around your opponent.
