i agree. i reckon that the game has alot more playability after you've completed it. With the catwomen missions only providing four levels i feel kinda cheated.
Adding a playable campaign for either robin or nightwing would be a great improvement
catwomen is really fun to play with, Shes also a nice twist away from playing batman all the time
a lot of people are saying the same thing. tbh i dont see it being much different from the robin dlc
it did come out on pc. but there wasn't a major hype about it. personally i prefer the pc version as it seems alot nicer to play
