A new downloadable content (DLC) update for Batman: Arkham City, featuring Harley Quinn, will launch next month.

 
The update is called Harley Quinn's Revenge and is slated as the "final chapter" of the game, suggesting there will be no future updates after this.
 
For those who did not buy the previous DLC, the Game of the Year Edition will be a good deal, as it will include the core game, the Catwoman, Nightwing, Robin and Harley Quinn updates, as well as the Skin and Challenge map packs and the Batman Year One animated movie.
 
 
The new content will feature Harley Quinn and her gang of thugs and will set Batman and Robin, who will be playable in a mini-campaign, in a last ditch effort to shut the gates of Arkham City forever.
 
The DLC will launch on 29 May and will be available for the Xbox 360 and PlayStation 3. UK gamers will have to wait until 7 September for the Game of the Year Edition.
