Such a wired thing. I installed cawoman + robin DLC. Works. Wierd thing is, when i start a new game, it starts with cawoman, i canno choose which character to play with. And robin, where in the hell is him? Why i have to play a new game just with that kitty? Robin doesn't have a storyline?
With the Catwoman DLC it incorporates her into the Batman campaign, so yes she at the start where you rob a safe or whatever but then it starts the intro with doctor strange just like the regular Batman story mode. If you beat the batman story mode you can just select any of her individual episodes in the main menu.
As far as robin and night wing thats under the riddler stuff in the main menu
