Character Differences (Knight)
- The Minigunner is replaced by a thug while playing as Harley Quinn, Catwoman, Red Hood or Batgirl.
- The Detective mode jammer is replaced by a thug while playing as Catwoman or Harley Quinn.
- There is a hidden passageway behind some bookshelves. It's visible on detective mode. In Arkham City, it's only accessible by the members of the Bat-family, but can be used by anyone in Arkham Knight.
- Exclusively in the Arkham Knight remastered version of the map, when playing as Batman, a piano can be played to reveal a crime board with notes consisting of multiple numbers and witness notes, similar to the one in Arkham Origins. The board appears to be an investigation into a murder prior to the start of Arkham Knight Batman was working on. Another prominate feature is what appears to be a cell door with 4-25 written on top of it. Some have speculated that this is tied to Rocksteady's upcoming announcement in April. Or it could be Batman's investigation on his parent's killer.
- When the date arrived, a moderator posted a birthday congratulation for Joker, as he first appeared in the comics 76 years ago that day.
- This is the only challenge map in Knight where Harley Quinn is the announcer; However, she never actually talks unless the voice synthesizer is used too much.
