well, this is actually really funny. I played the first zombie map with my mate, and we didnt do any glitches and made it to round 44. It was split-screen, so if you do look me up it wont be there. Ayways, my mate was just doing laps in the random box room - between the pillars - and i was doing laps of the entire building.... somehow we managed to run into each other only like 5 times, but neither of us got downed. The same things works in verruckt, but you always get stuck on the stairs because they're small.
