I was playing in a 3 person game last night and someone showed me this. I've never recorded any gliches but I'll try to explain it. This works with 2, 3, or 4 palyers. All palyers except 1 go into the tunnel in the back by the catwalk and press up against the wall behind them. 1 palyer goes and stands in the room above them. You walk into the corner of the column diagonal to the window wich is right above the players in the tunnel. In fact you can see the other players thru the wooden floor. When done right the zombies will go and gather by the telaporter. The guy upstairs will get some zombies at the window in front of him that he must kill but there won't be all that many.
Now the key to killing the other zombies is this. Every once in a while the guys in the tunnel move forward a little and a swarm will run down the stairs. Kill them then move right back to the wall behaind you again and so on. This does work so have fun.
The way u want to do this glitch is 2 people down in tunnel 1 person in corner by the hole and 1 person near window to help guard it
I find having 1 person up there gets overwhelming fast
and everyone should try get monkeys asap
