Really enjoyed my time with this one, even the sewer section is fun. The level design is great, I rarely got lost, hadn't use the map once, I just explored everything I saw.
I especially liked the traversal in the apartment building, not every door can be accesed through the staircase and it was really cool to find alternative ways to get into them.
Readables were really interesting while being lore-friendly, some funny ones are also in there.
At parts I almost forgot what the main objective even is but not in a negative way, it's just a fun map to explore.
Only complaint I have is I got semi-stuck and had to reload a couple of times because I couldn't get "unstuck", some areas are pretty cramped.
Overall excellent mission, especially for exploration.
