It makes no sense to me that Rocksteady would go to all the trouble of creating multiple characters, unique attacks and special weapons for both Robin and Nightwing, and then refuse to let you play as them in the main Arkham City post-game.
The above clipping is from IGN's quick preview of the upcoming "Harley Quinn's Revenge DLC. We already sort of knew that Robin would be playable, but him being stuck to just this mission is crazy talk.
Oh, and those stupid high score-centric Challenge Maps that the game is convinced we all so dearly love.
We can already switch between Batman and Catwoman in Arkham. Why can't we add Robin and Nightwing in there as well? Is there too much work involved with adjusting goon audio, making sure Riddler reacts properly if Nightwing solves a puzzle rather than Batman? Are Nightwing and Robin thematically lacking some critical gadget ability that the city requires to traverse?
Seeing as how we already have Robin DLC (with unplayable Robin) and Nightwing DLC (with unplayable Nightwing), and now we have Harley DLC with sort-of-playable Robin, it seems highly unlikely that I'll get my wish. Maybe they have a second Harley-sized DLC pack forthcoming that lets Nightwing headline. And maybe that's exactly what will happen. Because as I said, going to all of that work and then limiting the character to stupid Challenge Maps is just nuts.
