Call of Duty: Black Ops Cold War's Nuketown map doesn't come out until 24th November - but it's Easter egg has already been revealed.

Redditor PimpOutMyPC, who uploaded gameplay footage of Nuketown to their YouTube channel, claimed they glitched into a custom game in order to get into the map.

The Easter egg involves shooting the heads off all the mannequins - previous Nuketown Easter eggs have worked in a similar way.

Doing so in Black Ops Cold War's Nuketown, which is set in a post-apocalyptic 1984, flips the visual style, applying a blue '80s-themed digital filter to the graphics.

Activision released an official video for Nuketown yesterday, and clearly doesn't want the map to be seen ahead of its release.

Treyarch has form when it comes to elaborate Nuketown Easter eggs.
