As shown in the video, the team set up a zombie head wall of sorts somewhere in London, all under the pretense of being a perfect photo opportunity this Halloween. However, the dismembered zombies head were hiding a naughty secret underneath, as they can be rather violently expressive at times, making for one of the more enthusiastic COD Vanguard Zombies prank promotional materials.

Men, women, and even a dog all fell victim to the zombie heads’ occasional growls and moans. However, some were more unlucky, as they found themselves getting spewed at with disgusting goo. A particularly unfortunate guy in a white shirt found himself spattered completely red, which is a bit over the top, but incredibly effective in making a mark.

COD Vanguard Zombies will be releasing on consoles and PC this November 5.
