The latest Call of Duty: Advanced Warfare Exo-Zombies video has shined some much needed light on the mode's backstory, showing off its all-star cast in action.

According to the trailer, Atlas Corporation drops a bomb with the hopes of finishing a war. Instead, it unleashes a "freak show." Indeed, we do see tons of augmented zombies tearing through hallways and wrecking everything in sight.

The new DLC will include some of TV and movies biggest characters; John Malkovich (Con Air), Bill Paxton (Aliens), Rose McGowan (Grindhouse), and Jon Bernthal (The Walking Dead) as Atlas employees.

In the new trailer, Malkovich is seen mopping floors when he notices a blood stain on the floor. McGowan appears to be a security administrator. Paxton looks like a high-ranking executive. Bernthal seems to be a security grunt.

The DLC will be coming to Xbox One and Xbox 360 first on January 27th. PC, PlayStation 4 and PlayStation 3 owners will have to wait for an undetermined time for the chance to take on the zombies.
