PlayStation 4 players who participated in the Call of Duty: Black Ops III beta can now download their free theme, which Activision is giving away as a “thank you” to fans.

The free theme can be accessed through the Black Ops III “Themes” tab. You can download the “Morg City Zombies Theme” theme there. The free theme is based off of the noir-inspired, 1940’s setting of the game’s zombies mode, entitled Shadows of Evil.

You can get a better look at the theme in the video above. The Call of Duty: Black Ops III beta was held in August. The beta was started first on PlayStation 4, then came to the Xbox One and PC after.

Call of Duty: Black Ops III releases on November 6th. The game will release on PC, PlayStation 4, and Xbox One. The game’s zombies mode will feature many actors, including Jeff Goldblum, Ron Perlman, Heather Graham, and Neal McDonough.
