Achievements reveal playable Nightwing in Batman: Arkham City

More Achievements for Batman: Arkham City have swooped dramatically out of a dark corner, this time for DLC. Two achievements make reference to a "Nightwing Bundle Pack," featuring a playable version of Nightwing (the original Robin, Dick Grayson, all grown up).

The (unofficial) reveal of Nightwing brings the playable cast to four, including Batman, Robin, and Catwoman, with Robin and Nightwing exclusive to downloadable content. If you're concerned about too many characters crowding out your brooding time as Batman, you can always ... just not get the DLC.
