lol ya those were the brutus anims, they dont really work with the normal zombie models, it kinda stretches their arms but thats it 
I thought they looked familiar.

Did you also use that anim on the Engineer in CPH?
I went through it on co-op, and 20000 seemed to be alittle low for the ending. Also the lack of a pack-a-punch was kind of dissapointing.
I think it depends on what strategy you use. Hitting the box is in the long run a bad idea because the guns run out of ammo quickly, but at the same time it's hard to get ammo for wall weapons when you have the sprinters coming at you. I do agree though; once you get the hang of the map, 20000 is way too low.

The PaP not being there there wasn't too bad because the weapons do drop the zombies (I still want it though

)
