this glitch was patched on xbox live. but if you are offline you can get on the table. 1.When the level starts, go to the window that is southwest (Or northeast depending on how you look at it). 2. create an l shaped break in the window with your knife or gun. 3.Fix the barrier so it looks a little bit like an l.4. jump on the bars of the barrier, turn so your facing the table and jump. 5.Hope you get lucky and make it. note:if you run out of ammo and leave the table,you have to repeat the process. also, zombies can mess this glitch up and break the barrier.
