Modern Warfare players will have other goodies to try. There is a new multiplayer map, Cheshire Park, and the return of an old Call of Duty game mode, Team Defender. The latter is a spin on Capture the Flag, in which flag bearers earn points while keeping the target. You will also find other packages in the shop, including the new operator Roze.
The update will arrive only a couple of weeks after the start of the fourth season. It will air tonight at 11 PM PT (2 AM ET).
You will need a lot of free storage space to install it, however: it will measure between 22-36 GB, depending on whether you have it Modern Warfare installed or simply Warzone, with a secondary download of around 3.5 GB for console players. After the upgrade, the total size of the installation for Modern Warfare will be slightly larger, and that of Warzone it will be a little smaller.
