It leaked in spectacularly blurry fashion earlier this week, but now Activision has revealed the official trailer for Call of Duty: WWII’s Nazi Zombies mode. They’re going down the fully fledged horror route this time around, and the trailer looks frankly insane.

With Nazi Zombies, we’re creating a frightening world full of terrifying characters and events that will make you jump and look over your shoulder.  There’s an incredible amount of myth and lore, which our team has poured through in our development,” said Glen Schofield, studio head and co-founder of Sledgehammer Games.  “This is unlike anything before, we’re taking players to some very dark, grim places in Nazi Zombies. This is one hell of a horror experience.”

There’s an all star cast lending their likenesses to the Nazi Zombies story, including David Tennant, Elodie Yung, Katheryn Winnick, Udo Kier and Ving Rhames. The co-op zombie slaying experience takes players into a terrifying labyrinth of occult Nazi experiments, with all sorts of twisted creations lurking.

“We couldn’t be more excited to showcase our reveal of Nazi Zombies here at San Diego Comic Con. It’s been great to return to creating a horror-based experience, and with Call of Duty, head back to the Nazi Zombies roots. The team at the studio is proud of the opportunity to deliver something special for the fans,” added Michael Condrey, studio co-founder.

Nazi Zombies will be included with Call of Duty: WWII when it launches on November 3rd for PC, PlayStation 4 and Xbox One.
