One of my favorite rooms we did last year was complete black out. Then had someone with a remote control hit a camera flash up to the ceiling so you dont completly white blind the people so they could see a sign that says exit. second flash came a few seconds later but now there was michael myers in the room, thrid flash he appread on the other side of the room, 4th flash he gets closer to patrons and basicly pushed them towards the exit. All you need is two people with michael myers mask and black cloth the whole room and have two extra black cloth so they can hide behind or jump out. it was EPIC!
