Good mission, quite different from the others. I too felt that some of the places were too spacious (manor especially) but generally this was very enjoyable mission. It was hard, but not too hard on hardest difficulty. I actually didn't use almost any equipment, since I was afraid I would run out of something. I played this mission in about 1 month time span (took 4 hours in total), so I had some issues remembering all the details and tips. Needed to use walk through in two occasions,
I got stuck several times but can't remember the places, sorry. I use quick save often, so for me it wasn't a problem.
I'm waiting for the next mission anxiously!
