As seen by a Reddit user, according to the recently updated PS Store page, the game apparently supports “4-player multiplayer”.
However, it’s worth noting that the game’s description still gives more information about the game: “both in solo play and with another hero, patrol Gotham’s five distinct districts and keep an eye on criminal activity wherever you find it.” It was previously announced that Gotham Knights could be played by two players with all four characters: Robin, Nightwing, Red Hood, and Batgirl.
It could be a simple description error. There is also a chance that only the PS5 and Xbox Series versions will support four players. Either way, we won’t know until WB Games Montreal officially announces something.
Gotham Knights will be released on October 25, 2022 for PS4, PS5, Xbox One, Xbox Series and PC.
