Advance Warfare's new trailer shows the story line.

The new Call Of Duty: Advanced Warfare Exo- zombies video reveals some information on the mode’s back story and shows off all of the all star-cast in action.

In the trailer, Atlas Corporation drops a bomb hoping to end the war, but instead it brings out a ‘ freak show’. And yes, we will be seeing many zombies tearing through the hallway and destroying everything on sight. In the previous month, Activision revealed that the game Exo-Zombies will be including John Malkovich a con air, Bill Paxton (Alien), Rose McGowan (gridhouse) and Jon Bernthal (The Walking) as Atlas employees.

The new trailer will be showing Malkovich mopping floors when he notices a blood stain on the floor. McGowan appears to be a security administrator. And Paxton, well, he looks like a high ranking executive and Bernthal, a security grunt.

The game, Advanced Warfare's Havoc DLC will be coming to Xbox One and Xbox 360 on January 27. And will come to PC, PS4, and PS3 later on.
