Warzone 2.0 will come out on November 16, about two weeks after Modern Warfare 2 came out on October 28.
This is a first for the Call of Duty series. This should lead to parity and a consistent set of features, giving the series a new start.
Warzone 2.0 adds a new desert map called Al Mazrah. It also adds its own twists to the battle royale formula, like having multiple circles appear at the end of the game.
It will also have a new AI faction, Strong Holds that store loot and are watched over by NPCs, and a changed Gulag system.
There will also be a new sandbox mode called DMZ, which sounds like Warzone's version of Escape from Tarkov, even though details are still scarce.
Modern Warfare 2 will also have third-person playlists, which are similar to the third-person mode in the original Call of Duty: Modern Warfare 2 from 2009.
Ground War will be shown off in a big way, with 32v32 battles on the Sariff Bay map. There will also be smaller 6v6 matches on the three maps Valderas Museum, Farm 18, and Mercado Las Almas.
And finally, there was news about Call of Duty Warzone: Mobile, a new project that has some of the same features and promises shared social features and cross-progression.
It's being made by a group of studios, like Beenox and Digital Legends, and will be available on iOS and Android next year.
