The ability to play as additional characters from Batman-lore is one of the few areas the Arkham franchise hasnt perfected. Catwoman did have some stellar if not fleeting moments in Arkham City, helping to satisfyingly mix-up the gameplay to give the Bat a breather. However, Nightwing and Robin were disappointingly only available to use in Arkham Citys challenge mode. To really score a homerun on the extra playable characters front Rocksteady need to stop limiting our use of the non-Batman personnel. You should be able to explore the streets as the other Bat-Family members at your leisure, laying waste to thugs using their unique combos list. Azrael, Red Robin, Batgirl and Jason Todd are all characters whose attendance at Rocksteadys Batmans final hurrah would be greatly appreciated. Harley Quinn who had a juicy little segment in the Arkham Knight trailer is the only additional playable character who has thus far been confirmed. Though this addition is loaded with possibilities, we hope to hear more similar announcements at E3.
