A suit based on 2022's The Batman was reportedly added to Arkham Knight, a full eight years after the game's release. The update was only made to the Epic Games Store version of the game, before quickly being removed. This is expected to have been a mistake on the developer side of things, though WB Games has yet to comment on the mishap in an official capacity.
