Once the Robin and Nightwing DLC was released for Batman: Arkham City, most people thought that would be it for additional content for one of the best games of last year. That doesn’t seem to be the case as PS3Trophies.org has dug up some new trophies for a new single player DLC offering that is coming soon.

Based on the trophies listed on the site, the Harley DLC looks to be a pretty robust single player adventure that will add ten new trophies to gain. Little about the storyline can be gleamed from the trophies, but it seems to involve infiltrating a secret base that is most likely where Quinn is hiding out.

There’s no word as to when the DLC will be available or how you’ll get it. There’s a chance it’ll be a standard download, or it’s possible it’s something new to be included with an upcoming “Game of the Year” edition of the game.
