Quote from moconnorMap looks very cool Josh, but I think it's way too open, 4 people could easily stand up on the bed and keep reloading. You should put the start point with ammo somewhere more difficult to defend.
I'll probably fill in some of the open space once I actually test it with some real people but the bed is probably one of the more exposed areas in the map due to the fact zombies can climb up all sides of the bed.
