Batman: Arkham Universe - 10 Leaked Details You're Not Supposed To Know
9. Multiple Playable Characters - Usable In Free-Roam
Onto gameplay, and we'll apparently be getting a fully playable Bat Family.
Comprising Batman, Robin (Tim Drake), Nightwing, Batgirl, Batwoman, Catwoman and Red Hood, the one that sticks out is Batwoman. Having formerly been referenced in Arkham Knight by leaving a voice message, we know Kate Kane exists in the world and is active in costume.
Providing we are continuing in the same timelime and this isn't anything of a soft-reboot, we'd have to assume Kane married Maggy Sawyer (she mentions a wedding) and is now a bigger part of the overall story. Good on Rocksteady, if this is the case.
As for the others, their combat models were established across Arkham City and Knight, so it's more a case of Rocksteady expanding on movesets rather than generating a bunch of new animations.
