My building's internet went out, while I was playing with Artestdood against a bunch of idiots. A sniper on the first stage of gold rush just let me shoot him with the Ambasadoor at long range. Sure, I missed the first 3 shots, but he didn't seem to notice at all. Got a head shot finally, then a second shot off, but the sniper had the danger shiled on so he still had a few points of health. Now, I figured he would just gone back to spawn, just he was on his spawn's roof. Backed up a few feet, and there he is, still sniping.
All this over 15 seconds. While I was just standing there, in the open, no one paying any mind to me.
