This mission is buggy, mainly in regards to AI. Their patrols also seem to be random at times, making it impossible to predict where they were moving without avoiding them all together, which made things frustrating when trying to get loot (the Hammerite's room). Other times, I got spotted for seemingly no reason (walking around on the wooden rooftop) and others guards would run around for no reason, making me wonder if I got caught or if it's just scripting. For a first FM, it's pretty damn impressive, so I don't mean to bag the author or this mission's place in history, as it's a short but decently well designed level with a surprising amount of detail, but I can't say I enjoyed it.

Also, being able to knockout people makes this level super easy. The "impossible" difficulty removes this feature. I'd typically say that's the best way to experience this, but because of its buggy nature, it's not a fun challenge.
