What happens when you turn on the power in call of duty black ops Kino der toten?

The curtain opens and allows you to access the teleporter (which can teleport you to the pack a punch machine).

It opens up the door between the lobby and the theatre.

The boards above each mystery box location will have a light on showing where the box is at the time.

You can access the "perks-a-cola" machines.

Another sort of zombie is introduced to each level (except dog rounds). These Zombies crawl on 4 legs and when you kill them they explode with a green gas which makes the screen go blurry if you walk through it and also damages you if you are standing on it when it explodes.
