Higher level Kino der Toten Strategy

This guide will tell you what I did to get to around 30 on Kino der Toten (I stopped because I got bored, took the teleporter, threw all my monkeys in the room, and waited. best way to die :)). Alright so from level 10-25 I didn't really strategize I just killed zombies. Then from there on I started this strategy where you make a figure 8 on the stairs. You need the Thundergun. You climb up the stairs in the theatre room, then jump down. Cross over on the ground, climb up the opposite stairs, then jump off into an area where their isn't zombies. I'll try and get a video posted up later because that's really confusing to explain.
