Gamers are angsty and many suffer from
unskilled and unaware syndrome.
I got noobed so hard last night. It was a 2v2 and my teammate decided to camp on top of one of the buildings with a .50-cal sniper rather than do something useful. While I ended up racking up 40 or so kills, he had like 3.
Anyway, at some point he goes, "I think someone's in the building I'm in. I heard them awhile ago." So I head over there and crouch around the first floor. I don't see anyone so I proceed upstairs to the second floor. Again I don't see anyone, so I head upstairs again and peek out at the roof, look around for a second, and turn to go back downstairs. BAM. Knife right to my forehead.
Apparently they had been crouched and following behind me for quite some time.
