It will be listed like any other Call of Duty title on the PlayStation Store, Xbox Store, or on PC (you'll need the desktop app for PC or Mac to download the game). You can, however, download Warzone as a standalone title – which, indeed, most of you will likely end up doing if you won't already have Modern Warfare (2019). The size of the Warzone download will vary depending on whether you've downloaded the latest patch, though – 18-22GB if you have, and more like 80GB if you haven't. If you have Modern Warfare (2019), you simply load up the game, and head to the Classified panel in the game's main menu.
