Five Strategy: Elevator Strategy

This strategy is for 1-3 players. It will work with four, but it gets crowded.
In this strategy you should have all your weapons and perks already. You stay in the first elevator, the one from the first floor to the war room. It's the smaller one. Stay in the elevator looking out towards the first floor. Anytime the zombies overwhelm you push the elevator button to go down, and then push the button again to go back up and face the first floor hallway. Repeat for a success!
