As promised, Batman: Arkham Origins will be getting story-based DLC. "Cold Cold Heart" will be available on April 22, and it will tell the origin story of Mr. Freeze in the Arkhamverse. Described as a "mini chapter of the game," this add-on will include in-game missions alongside a brand new story.
New gadgets will also be introduced in the expansion. Of note is the XC, short for "extreme conditions." It will change gameplay to make Batman more resilient to the extreme weather effects of Mr. Freeze's henchmen.
The new trailer can be seen in minute one of the video below. The DLC will be available on PC, PS3, and Xbox 360--but not Wii U.
