Treyarch's Call of Duty games and zombies modes are inseparable at this point and fans of the zombie mode wouldn't have it any other way. This year, Call of Duty's zombie campaign titled "IX" is punctuated by a vocal song from Avenged Sevenfold named "Mad Hatter." Treyarch has released the song in the form of a music video which contains some new footage of Black Ops 4's zombie mode.
