I found this out the day the map was released its really useful, also you can fly over the gates in the maze but u CANT fly over the maze you do still have to navigate it. I love this thing you can get a TRAIN of zombies and have them disappear in the blink of an eye or just fly over them if shit gets hairy
FYI, Super ez way to build up points with no ammo use this tap trigger once or twice and then use the knuckles to finish em off EZ money with no investment of ammo =D
