A trailer for the last map of Treyarch Studios’ long running Call of Duty Zombies series has been released.

The final map, entitled Revelations, will be a part of the Salvation DLC, the fourth and final expansion for Call of Duty: Black Ops III. The trailer hints at much of the Zombies backstory, including the origin of The Shadow Man and the identity of the mysterious Dr. Monty. Revelations will mark the end of the Zombies storyline that had started in Call of Duty: World at War.

Black Ops III’s Salvation DLC will release for the PlayStation 4 on September 6th. It will likely release on the Xbox One and PC a month later. Along with the Revelation map, Salvation will include four new multiplayer maps: Outlaw, Citadel, Rupture, and Micro.

Even though Treyarch’s Zombies storyline may be wrapping up, the upcoming Call of Duty: Infinite Warfare will have its own Zombies mode. The mode is called Zombies in Spaceland, and will take place in a theme park in the 1980s. Players will be able to take control of one of four ’80s movie-inspired characters: the jock, the nerd, the valley girl, or the rapper. The voice ensemble will include Seth Green, Ike Barinholtz, Jay Pharoah, Sasheer Zamata, and David Hasselhoff.

Call of Duty: Black Ops III is available on PC, PlayStation 4, and Xbox One.
