Just finished the level. Really fun for a first level. I can't remember the score I got, but I got the A+ ranking. I liked the use of silenced weapons, like the silenced uzi. Felt that it fit Richters use of the silenced uzi in the firs game.
Think my favorite floor was the third one, because I like levels where you can get great combo chains, as well as still being challenging. It felt more like a HM1 level because there was different rooms for different people, and you don't get shot from the other side of the floor, which is a good thing.
My least favorite floor was probably the first one, most likely because of the guy in the beginning. Since you die a lot in the game, you always have to lure the first guy in the room with the gun towards you, which got tedious because I prefer more fast paced gameplay for the levels.
The level was balanced good, it didn't have too many dogs or the black guards, which is good compared to the hard mode of HM2, which did not do a great job of that. I also liked the silenced uzi in the level, because it was a rare gun to find in HM2, and I also liked the cutscene at the end.
