Absolutely sick map! The visuals are stunning, the gun and perk vareity is awesome, and the map is decently large. The teleporter zombies aren't nearly as annoying as the ones using ZTC mod, and the boss didn't give me too much trouble (especially when I got the Wunderwaffe ). I also enjoy that there's a decent bit of space to run around, but not too much as to make the map too easy.
There were only a few small issues, none of which are mapbreaking but got on my nerves just a little. The main issue I ran into was the fact that it was easy to get stuck permanently, which for me, happened in the elevator when i jumped as the elevator reached the underground, and the ladder underground, which I jumped onto to get up quicker. Luckily I was in the lower rounds when they happened, but at a later round, it could be very frustrating. The minecart track in the underground was also kind of frustrating, as it was very easy to make an irrecoverable fall (again, happened to me twice). The other issues I ran into are extremely minor, the near pitch black darkness of the tunnels (bumping up my brightess a few notches made it seeable), and the zombie counter showing negative values at higher rounds (didn't affect the turn of the round, the round ended when all zombies were eliminated, not when the counter reached zero). None of these issues are mapbreaking and don't subtract from the awesomeness of it, but they did cause me a few game resets.
One thing that puzzled me was how exactly to find the Pack-A-Punch. I'm assuming it's behind the door in the castle which yeilds the text, "Come back later...", but I don't have the slightest clue as to how it would be opened. If you could give me a few pointers, I would be thankful, I really wanna try out the double PAP weapons in the map. I can tell that you spent a lot of time on this map, it's a hell of an experience and I had a lot of fun playing it. If only I could get multiplayer to work so I could play with my other friend who plays WAW, this map would be really fun on multiplayer.
