Thanks for you contribution, but it's unplayable in KF.
It's just too open/big map where you have to go hunting down zombies yourself, while it's supposed to be the other way around.
What would be the point of survival game if the maps are made in the way you won't need to do anything in order to survive?
Even maps such as Arcade-Gasstation tend to be a bit too open, but they're still playale.
