A new field upgrade is being added called Toxic Growth. Things are surprisingly restrained on the Zombies front for now. Yamantau and Diesel are in at the beginning of the season, while Standoff and Duga will be added later on as the season continues. The maps include: Yamantau, Diesel, Standoff and Duga. There are however four new maps for Call of Duty: Black Ops Cold War players to enjoy in standard multiplayer.
There's no new big Warzone map this season.
