DC All Access is showing off what we can expect out of the Batman: Arkham Origins "Cold, Cold Heart" downloadable content, and it looks like DC is taking a page out of Iron Man's playbook. To deal with Mr. Freeze, Batman will equip a suit that will help him take on all things ice-y.
There will be civilians you need to save frozen in ice, some enemies will use ice guns, and they're all messing up Bruce Wayne's mansion. The video also teases that Mr. Freeze is working with another major crime lord of Gotham.
The Cold, Cold Heart DLC will be out on April 22 for the PlayStation 3, Xbox 360, and PC. The Wii U gets NOTHING. Also I think the voice actor for Mr. Freeze is the guy who voiced Brain from Pinky and the Brain.
