I played this last night.
Main Menu: Very nice...although very derivative of Doom3. With that in mind, I expected the level to be something very similar to Doom3, but when it begin I was in a corridor made...stone!? It seemed somehow like you taken inspirational from some bits of your level from Doom3, and others from what I imagine Castle Wolfenstein must be like (I haven't played it, but the spiral staircases, the uneven stone-work on the wall, it made it feels like a castle).
The sound was very atmospheric, and I did enjoy being scared by it
The level was also lit well too, though occassionally the shaders looked out of place. The p90, for example, looked white. I assume that's not how it was supposed to look. While we're talking about weapons, I have to say that the last guns you picked up, i think it was a colt45, was quite honestly one of the best-looking weapons I've ever seen in FPSC. It was just so...

I want it, please tell me where you got it.
I wasn't a great fan of the zombies popping up behind you, and there was one enemies, a small one, that didn't appear at all hence i died. I had to look for its shadow in order to shoot it.
The box stacking at the end came out of the blue for me. I expected a big gun fight. I mean there was that room with all three types of ammo on the shelf; I saw that and thought "uh oh, boss fight coming up". It did enjoy it though, but I somehow thought the pressure could have been piled on a bit more. I know how.
Overall, a very good start. I think this level has a few identity problems but it still did a very good job and keeping my interest, but above all, scaring me just before I went to bed.
7/10
