"Cold, Cold Heart" will be the inaugural downloadable story content for the WB Montreal-developed Batman: Arkham Origins. The story will focus on the origin of Mr. Freeze and his initial confrontation with Batman.

In regards to the new DLC's length, Creative Director Eric Holmes noted to a fan that its length will be similar to that of "Harley Quinn's Revenge," the only story DLC released for 2011's Batman: Arkham City.

“Cold, Cold Heart” will be available on the PlayStation Network, Steam and Xbox Live on April 22nd, 2014.
