As Rokinath mentioned this FM is like a mix of Thieves Guild and Shipping & Receiving missions (from Thief Gold / Thief 2 respectively). I never especially liked those missions, but Saints & Thieves is an improvement over them in my opinion. We have a nice city mission consisting of Watch station, warehouses and sewers. There is even an automap feature, which is rare in FMs. Objectives were mostly straightforward - i only struggled to open the secret passage using the code. However after watching Marble Man let's play on Youtube i found the solution. Thats why my final score for this FM is not 10/10, because it wasn't clear for me what to do. Other than that a great mission.
