The first batch of story driven downloadable content for Batman: Arkham City was released this week, months after the initial launch of the original game. We decided to don the cowl and take to Harley Quinn’s Revenge for your viewing pleasure.

The video above contains spoilers. If you haven’t beaten Arkham City yet, I suggest you walk away. Really, you’re missing out on one of Batman’s greatest stories. So, ignore this if you’ve not finished the game.

Otherwise, enjoy!
