Played 2 player and beat it in 42 minutes.
Pretty fun and hard map. Most of the weapons are quite weak, but the shotguns and snipers perform quite well in the 20s. You really have to know how to guide the zombies and run circles quite well to beat this. Camping probably wouldnt work too well because of the weapons.
I had 3 downs and my friend survived with no downs at the ending. I wasnt able to buy strength or more than 2 perks but we were able to beat it.
Wow congratulations! I hope you enjoyed it enough to play again. One of the really cool aspects of the map is that it will never be the same game. So every time you will see different guns and have to deal with different rooms etc. I remember from all my testing that I would go through 20-30 games and I still wouldn't see everything. But glad you liked it and were able to beat it!
