A new map for Call of Duty: Black Ops 4’s Zombie mode is going to be available very soon for fans of the Call of Duty series.

This upcoming map is part of the Chaos storyline. The Chaos storyline is a completely separate narrative from the main Black Ops 4 story. Chaos focuses on explorers from 1912 chasing after a secret order. They constantly come across supernatural forces, and keep finding themselves fighting zombies in variety different places in the world.

A trailer for the new Chaos map, called Ancient Evil, has been unveiled. The trailer showcases the four main characters fighting against the supernatural in an area that looks like ancient Greece. They fight against zombies, skeletons, and a giant with multiple arms. They also come across a Pegasus, who may or may not help the players through the map.

The trailer also showed off more of the Black Ops gameplay that fans will probably like. There’s also several story teases within the trailer, possibly signaling the ending of the Chaos storyline.

The Ancient Evil will be available on PlayStation 4 first, and will release on March 26. Players need the Black Ops pass to get this new zombie map.
