2nd game I played, some douchebag was running around with the riot shield (or whatever the new version of that is) and the crossbow. He wouldn't shut up, just yappin' about random stuff. He was mostly being the typical pompous ass with the comments like, "Man, don't you know? You can't kill me!" "if you run into me, you're gonna die, it's just gonna happen".
This wouldn't be so bad, but he finished with fewer kills/lower KD than me and it was my second time playing the game, first time ever playing the map. Not to mention that 4/5 times I encountered him, I managed to kill him. One time I found him, hadn't reloaded in a while so I had to try to knife him around behind the riot shield, which I had done before, but he just started yelling "BRO YOU CAN'T KNIFE ME WTF" as he also tried to knife me. I finally said screw this, and I killed him in 2 seconds with my pistol.
