Painkiller is ****ing stupid. Try getting a quad while spawn trapping people on Terminal Domination. Almost all of them have it on. It takes 4 shots to the head with a Barret .50 FMJ and Stopping Power to kill a guy with painkiller.
Commando, I mean honestly, Who was the dipshit at IW that came up with it? But hey, at least I can hear their footsteps before they can knife me with my turtle beach X1's
