This mission is huge and has a bit of everything. After nearly 4 hours of play time i was still missing half the secrets and 2000 in loot so there must be some really well hidden optional secrets. My only issue with this mission is the location of two non-optional switches that were difficult to locate (the fire room switch and the master bedroom switch) but that may be my fault in overlooking them. Overall though i think this has become one of my favorite FMs.
