The story based action-combat addition to the Batman series, Batman: Arkham City may be coming out with some new DLC soon, according to Game Informer. Listings for leaked PS3 trophies revealed some future plot achievements, leading fans to believe that fresh content is in the works.

There are ten new trophies for a Harley Quinn DLC on, indicating a story-based add-on rather than more challenge rooms. The achievements range from civilian-themed quests, such as the Lost Property mission, to combat-based awards like the Snap To It trophy, which involves using Snap Flash on an unarmed thug, an armed thug, an environmental object and a Titan.

After its October 2011 release, the adventure crime-fighting game sold two million copies in its first week. The Xbox 360 and PS3 video game follows Batman's ultimate smackdown with the Joker, aiding civilians and encountering other villains such as Mr. Freeze and Bane along the way.

Arkham City racked up numerous awards at this year's Video Game Awards on Spike TV, including Game of the Year, Best Xbox Game, Best Graphics and more. The comic-based Batman release earned a total of 10 awards, sweeping the ceremony.

The developers at Rocksteady Studios have not announced any news on an official DLC release at this time.
