well here's something iv'e had a while bu i've just now decided to post it, sorry it's so late. Anyway this is an infinate level glitch for the old zombie's map (Nacht Der Untoten), the video is kinda short but sweet but you get the idea of how the glitch is down by watching me on video. Basicly you will run up the stair case, (this zombie map is based off the multiplayer map AIRFIELD) and stand at the corner you see me at, then then run and as soon as you get to the little hump jump and crouch then spin your body around. If you've done it correctly the zombies will stop infront of you and they cannot kill you so can take your time and just mow them down.

if your not sure if your in the glitch or not just have your buddy peak around the wall to make sure your legs are sticking out, if they are your in the glitch. Now one thing to be careful of when your in the glitch is shooting big guns such as the sniper rifle and mg42 will knock you out of the glitch and get you killed by the zombie's. i think that's it if anyone has any questions please leave a comment and have fun and enjoy this glitch.
