Warner Bros. today announced Cold, Cold Heart, the first story expansion for Batman: Arkham Origins. The content is described as "extensive," and will launch April 22 for Xbox 360, PlayStation 3, and PC. The content is not coming to Wii U due to a lack of demand.

The Cold, Cold Heart expansion has players exploring the origin story of Mr. Freeze, where they will learn about how he became one of Batman's fiercest foes. The DLC is included with the $20 Batman: Arkham Origins season pass or can be purchased separately for $10.

Cold, Cold Heart takes places in various Gotham City locations, including Wayne Manor, and gives players the new Batman Extreme Environment (XE) suit and gadgets like the Thermal Gloves and Thermocharged Batarangs. In all, the Cold, Cold Heart expansion is said to span "several hours" of gameplay.
