You can tell Venus to remove the turnstile. Thank goodness. Why is it even there in the first place?
New music was added for this scene where you meet "Nines". It doesn't fit at all.
This is the only major bug I've encountered. The game wouldn't remove the Museum and the Giovanni Stronghold from the map, and I could still go there for the rest of the game.
The Anarchs got a new hotel for the Anarch ending, with guards and everything. Makes more sense than going to the Luckee Star. Besides, I don't have to see Hatter's corpse again.
If you helped Yukie kill the sharkman, you will meet her again at the end in front of the Kuei-Jin temple.
It's the same voice actress. These are unused lines.
Once you've killed everyone here, you can persuade her (I don't know how many points you need) to open a portal which leads directly into Ming-Xiao's chamber. This makes no sense, but it skips most of this boring level.
While I appreciate the effort, something smells off about this entire sequence. Her fight AI has problems with doors, always gets stuck on them. Then she has this creepy stare in her eyes. And a short cutscene of the opening portal would have been nice too. Yuki will most likely be inside the building when you ask her to open it. Then she just says "ok" as if it's nothing, and you don't see or hear anything. A clueless player might just continue to the next map and miss the portal.
According to the walkthrough you can also persuade Chunk to let you go directly to the sheriff. It didn't work for me despite having 10 points in persuasion. Maybe I've picked the wrong options.
