This is a great map, the amount of detail (especially in the cave area) is awesome. I need to figure out how to enable noclip to see all the neat little things you put in it.

The only suggestion I have would be to give the shotguns the fixed crosshairs for hipfiring rather than the rifle/SMG style where they become less accurate on the move, and probably change the KS-23 to have a 3+1 round mag and a whole wack more damage (It's a 6.23 gauge/23mm shotgun after all).

I managed to get PAP unlocked, and find all four rocks for one of the quests, and now when I kill zombies in the PAP room where the four found rocks now are Green tinted rocks will randomly fly up and out of them when they die. How long is this supposed to go on for? I've tried using the sword as well but it does not seem to have any sort of use for progressing the EE/quest, and I can't grab any other rocks if I start another quest.
