Not got the new maps yet because PSN is down

But there are people who camp - you see them running to the same hiding spot every time you kill them. This annoys me immensely.
I don't camp but if I know someone's going to run past me, I will lie in wait. Otherwise I'd consider myself more of a run'n'gun player. Love my commando rifle. Hardened pro to hit muppets behind windows and doors. Ghost pro and silencer for silent kills. Can't remember by third perk.
KDR tends to be around 3 or 4:1, with kills of 25+ depending on who I'm playing against.
