Designer Geoff Ellenor gave an interview to PLAY magazine, mentioning that Gotham Knights is truly massive. So much so that a single playthrough will not be enough to experience all the content:
“You won't be able to see everything in one playthrough. And that is because there is so much content that is unique to the character’s perception.”
Another developer, Wilson Mui, added:
“Structurally, the scenes will be similar and suited to an individual character, but each will have their own version. So, you know, they move differently, they speak differently, they have different histories with all the characters — this allows us to make a scene that would be their personal version. If you play as Batgirl, you'll get Batgirl's version, but if you play as Robin, you'll get Robin's version of that same scene. In some cases they'll be similar, but there will always be at least subtle differences.”
Gotham Knights will be released on October 21, 2022, on PC, PS5, and Xbox Series X.
