Call of Duty: World at War Glitches

Nazi Zombie Survival
Starting at about wave 5 open the help door and use the random box to handle the attacks until wave 10 and open the upstairs. Then, have one player jump into the glitch while the other mans the window in the far back, and the rest help with the heavy crowd up front. The glitch is on the broken wall in front of the trench gun, with a piece of wood leaning against the wall. Get a running start and jump into that corner between the beam and the wall. Then lay down and turn towards the shotgun all the way around until facing the bar. You should feel the turn slow down once your view is at the dirt in front of the glitch to know its activated. I have done this multiple times and every time i have been to 28 before the zombies broke the glitch from behind.
