I had a pretty fun time playing this mission. It has a few nods to old Thief-missions. The initial premise reminds me of "Ambush!" from Thief II and there are a few things that seems to be references to "Assasins" from Thief (the shop!).

It is a medium-sized city mission with little verticality (not much of a Thieves highway, even if you can get up on the roof on some buildings). I also think that it is okay in detail and execution. There are a few readables that will lead you to quite a lot of loot, so if you bother to explore, you are rewarded.

The athmosphere is there, and I think the use of ambiance is good.

All in all I liked it. Perhaps it could have trimmed away a few areas and elements and concentrated and developed what was left futher, but I personally like the open exploration too, so.
