Maybe a controversial pick, but I am not talking about the nice little slice of story that was Harley Quinn's Revenge. I am talking about the constant tantalising character news. Robin DLC? Wow, that's going to be great. We can see Robin's side of the story, and what happens to him in Arkham City, and it'll be so cool. Nope, he's relegated to the challenge rooms. Nightwing DLC? Wow, that's going to be great. We can see what Dick Grayson is up to. We can see why Nightwing is in Arkham City, and it'll be so cool. No. Challenge rooms. To add insult to injury, they are exactly the same challenge rooms as Catwoman and Batman, with only a few new additions. There was so much promise with where Batman: Arkham City could take a DLC. There is a glaring point in the game, right after the Hush mission, where he says that he's going to investigate it when he gets back to the Batcave. I don't think I'm the only one who was expecting a Bat Cave DLC, but it never came.
