The Security Shamblers

Well hello,this my first map,it focuses on a type of zombie that i like to call "The Security Shamblers" as you can tell from the name they are shambler heads inside security cameras,so good luck and don't let the bed shamblers eat you at night. Edit:I updated the map a little,so framerate should be better as i got rid of some ash,some lights are indestructible and you can't get out of boundary through the roof also i want to personally thank Tahazzar for helping fix all of the things above,he's a Deabolt mapmaker and he's far better then me so please go check him out.
