Support! It's an awesome map and i saw it when it was like half built when @Bakes32 showed me lol. Good luck!
I'm sorry but obviously you haven't read the paragraph and just looked at the pictures. This map is not human bias, and any place that is remotely bias has been modified so it can easily be flooded by the zombies when they swarm in. Maybe you should be a bit more open minded when it comes to this. The buildings upper levels are impossible to enter, and it is been tested for glitch positions, which aren't there. So sorry, but you need to read, not just look.
