Batmans Arkhamverse is nothing if not known for having a wealth of Easter eggs reinforcing how rich its lore is. Thats not to say its storytelling or writing has always been airtight, and yet theres a distinct signature the Arkham games have all managed to sustain and develop. Sometimes thats achieved purely in what signage and billboards are viewed, let alone what set pieces in the environment can be scanned via Batmans Detective Vision to reveal an acute character reference. The latter is where Ratcatcher belonged in a sad stasis of an existence, for example, until the upcoming Batman: Arkham Shadow decided it would feature him for the first time in-game.
