This mission took me a little time because after you've run around the same areas a few times, it starts to get a little disorienting, and either by accident or design, the map is no help.

Other than that, this was a lot of fun. Inventive and original rooftop set pieces, and unlike some thief missions, this one doesn't strip you of equipment. I found some gas mines that were super helpful.

The architecture is excellent, and the author clearly cared about the details. It has a lot of fun little details, including some interesting satire.

Don't get discouraged if you get turned around a few times trying to backtrack, though. Just try and find a new window to climb through, or check if there was a door you haven't tried.
Good luck, and have fun!
