Call of Duty: Black Ops obtained its season two upgrade earlier today, and a minor part of the newest content confirms that the long-teased arrival of zombies in Call of Duty: Warzone. A whole lot of calling cards added to the game (basically player banners connected to challenges) reference killing zombies in Warzone (seen by Eurogamer), with text including the likes of:”Back in Warzone, eliminate 8 zombies before the initial circle closes”

Various hints have been popping up in the games over recent weeks, including a challenge machine usually found in zombies mode, and in-game sound messages talking about the impending arrival of a cargo boat called Vodianoy at Verdansk. One of the sound scraps is the next:”Captain Rosental speaking. Russian ship Vodianoy… something happened. We had been transporting strange biological substance. What do?! There was an infection epidemic. I’m afraid we will not be able to include it.”

Beyond this it’s speculation. The ship’s going to crash-land into Verdansk at some stage, and no prizes for guessing the Vodianoy’s freight is hungry for intelligence. Substantial changes are incoming for Verdansk in general, with some thing”starting to emphasise underground” leading some to believe it’s likely to be getting nuked: that is surely one way to finish a zombie war.

The second season of Call of Duty: Black Ops–Cold War and Warzone starts tomorrow, Feburary 25. That also kicks off a free week of chosen Call of Duty multiplayer and Zombies content, including the new Outbreak manner, which will run till March 4.
