Blue dot in south offices, thats me. I snipe into the area where the red box is and anywheres in between.
The green dot at the bottom of the stairs is how I place the claymore, as they dont see it until its too late, since I have scavenger, I pull out my shotty and go reset it after it goes, off.
When I make a sniper shot and get a kill, I crouch right away, pop up and look and fire if there is someone and crouch again if there is not.
I normally only reload if I have 4 or less bullets left, sometimes I run out if I keep killing and people keep coming into view.
Thats how I posted the 61-4-4
Call it cheap or what have you, but I am only doing what snipers do.
