Batman: Arkham City ~ Harley Quinn's Revenge

 After the tragic death of The Joker, Harley Quinn goes into a deep depression, and becomes even crazier than she was. She then came up with a plan to Batman hostage, and get her revenge. But there's one thing she didn't take into account for, Robin. Now you get the chance to play as Robin, stop Haley Quinn, and save Batman.
 Personally this is one DLC I'm really glad came came out, because it finally gives you the chance to play as Robin in story mode. But there's a catch you can't really free roam around Arkham City, and you only get to play as Robin for some parts, but you do get to pick between one of the 3 downloadable costumes only if you've downloaded them, and you can only wear one of the outfits after you've started the game.
 The DLC comes with 3 new character trophies, Mourning Harley, Harley's Goon's, and Harley's Titan Thug.

 I rate this DLC a 4.5 out of 5, because this DLC makes it so Batman doesn't become another dusty game on your shelf. It only got a 4.5 because it didn't give me the option to free roam, in this it's like one big unending mission, because even after you beat the game you can't just free roam, you have to start the entire thing over again. But just like the other Batman games all the details and everything else is great.
