The Call of Duty app has leaked Outbreak, a new "large-scale" Zombies mode for Black Ops Cold War.
The mention of it, now pulled from the app but spotted by the internet, includes two images and the promise of a trailer. It looks like this one will be announced soon.
Activision has teased the arrival of Zombies in both Black Ops Cold War and Warzone recently. Last week, a Cold War Zombies trial machine popped up in Warzone, suggesting Zombies were on their way to the battle royale.
