I had 41 knockouts in this mission. I don't mind the number, but many of them were tightly stacked on top of each other to the point that if you knocked out one, 3 to 4 others would immediately run for the alarm. In one location, dousing a water arrow alerted 8 guards. It's a tough mission in terms of dealing with large numbers of guards alone.

Sound brushes are very messed up. In some places, sound cuts out mid-room, while other carpet footsteps can be heard from across the mission. That guard that sounded like he was walking right up behind me was actually 3 floors down. Meanwhile, opening a chest with loot about deafened me from how loud the sound was compared to everything else in the mission.

There are the typical: Paintings sunken into walls, Textures not aligned, etc, but not overly bad in this level.

Sounds replay constantly (bad placement of ambient markers that don't account for backtracking)

Overall, it was a good, functional mission that turned into a key hunt and backtracking for locked doors that I had to leave behind. This is a personal preference, and I'm sure I'll enjoy this more when I'm in the mood for more AI challenge and searching, rather than I am right now for ambience and good design.
