An upcoming DLC pack for Batman: Arkham Origins focuses on Mr Freeze, DC Comics has announced.

The DLC, Cold, Cold Heart, is a "big, open-world narrative-based DLC," according to WB Games vice president Ames Kirshen.

"We're super excited to give fans the origin of this great Batman character," Kirshen said.

"It's like a mini chapter in the game...This is in-game mission story content with a brand new story wrapped around Mr Freeze in the Arkham Origins settings."

Cold, Cold Heart is expected to be available from April 23 for Xbox 360, PlayStation 3, and Windows PC.

As reported last month, it will not be available for Wii U.
