First of all, I LOVE THIS MAP!  As a fan of Doom this was great. However I must admit it could be better. I think it would be cool to add in the Thundergun but reskin it to be the B.F.G. I personally am glad there is no solo quick revive as it adds a challenge not seen in a lot of maps now adays. On the subject of perks there definitely needs to be more. I feel that Mule Kick, Stamin Up, Deadshot Daiquiri, P.H.D Flopper, and Double Tap 2.0 would be great. Finally, if you could add guns in from Black ops one and two (maybe even three) that would be cool. I feel that every one I meet agrees that the World at War weapons suck in zombies. There are about 4-7 guns that are "good" and the rest either suck massive cock *cough* *springfield* *cough* or are just plain boring to use. But imagine if there was the Mp5k from Black ops, or the scorpion from Black ops 2.
I'm sorry my comment was so long, but I really like this map and want to see it evolve into a better map (not that it's bad, it's just that there's always room for improvement). This map has a lot of potential to be great map. Also make it easier to play the map in single and multi player. I hate having to use the console to launch a map
