Not only has war evolved in Call of Duty: Advanced Warfare, but so have the zombies that always threaten players' sleep and productivity.

The trailer above shows us a peek at the Exo Zombies that will have players fighting for their lives when the first chapter is released in January 2015 with the Havoc downloadable content pack. This will kick off the Call of Duty: Advanced Warfare Season Pass, which includes four total DLC packs that will come packed with multiplayer content, weapons and a lot more.

These zombies can leap like nobody's business and are as ravenous as a bunch of shoppers during the early hours of a Black Friday doorbuster sale. We're excited to try out the ridiculous new weapons and equipment on these undead foes, but we'll have to wait until January 2015 to get our chance.

You love the sound of zombies? You'll love the sound of the guns that off them.
