The Call of Duty: Black Ops 4 physical release requires a roughly 50GB patch on day one to be playable, although the new Blackout mode works after roughly 30% of the update is downloaded.
Call of Duty: Black Ops 4 is just around the corner, but a new support post has revealed both PS4 and Xbox One user will be met with the enormous download before they can play anything.
In a post to the Activision Support Page, Treyarch revealed that the patch is necessary to play Multiplayer, Zombies, and Specialist Headquarters on Xbox One and PS4. As a silver lining, series first Blackout Battle Royale mode will be playable at roughly 30% completion (around 16-20GB). The installation process should be simple enough on Xbox One, but due to the slightly more roundabout way that the PS4 copies data, you’ll need to jump through a few hoops.
