Update!
Added beacons and optimized it a bit more (basically the big metal boxes) also added some starting text and have set it up so that the zombie spawns really far away from the exit are disabled when survivors have to escape. Also got rid of the hidden room.

This map is really fast paced, a survivor victory can be achieved within 3 mins so zombies have to act fast
Objectives:
1. Press all the buttons in order (each one takes 30 seconds to process before the next one is available, except for the last one)
2. Escape before the place explodes! Blast doors start to close and if your not to the exit in about a min and a half you get sealed off
