(adsbygoogle = window.adsbygoogle || []).push({}); Mine is 23 so far . And 213 with the new glitch.

My best strategy is going to the power handle, open the door behind it and then go and camp up the stairs (with multiple people). You can go get the perks and go to the Pack-A-Punch machine (with the teleport nearby).

Rep+ and have a nice day .

15 with only 2 people

39 with 2 people. I did not cheat or glitch etc...

level 28, its freakin crazy!!!!

level 222 easy

34 Levels Solo. 69 Levels with 4 people.

22 without camping on the stairs (we went run-and-gun) . Would have gone a lot further but my friends xbox froze while he was hosting and the game ended :\

40 by myself and 31 with 2 people. The stairs at C is where I mostly go sometimes. Nazi Zombies on solo is soo easy because there's less zombies and and they're weaker. The Reaper and Porters X2 Ray Gun FTW!!!

35 with 3 peoples
