CoD: Black Ops 6 Taking up 300 GB on Disk Isn't Quite True. Game Requires Constant Internet Connection
A number of new information about Black Ops 6 has been published online. The game requires a constant internet connection in all modes, and the issue of the game's size has also been clarified. Furthermore, we learned the details of the Game release.

Activision has provided new news about during the Xbox Games Showcase.
Let's start with the fact that in the article on the technical page, there was a mention of the requirement for a constant internet connection.
To deliver the highest-quality visuals while also reducing the game's overall storage space on your hard drive, Call of Duty: Black Ops 6 will use texture streaming across all game modes.
This means you'll need a continuous internet connection to play any game mode, including Campaign. If you're on a console, Campaign can be played without a subscription service such as Game Core or PlayStation Plus.
The article also suggests that the game will provide a split-screen feature on Xbox Series X/S and PlayStation 5 consoles. Due to technical limitations, this option won't be available on XONE and PS4.
Size of Call of Duty: Black Ops 6 - explanation by CharlieINTEL
It's worth noting that there are reports online stating that Black Ops 6 requires over 300 GB of free disk space, which seems to contradict Activision's announcement about reducing the game's size. However, it's important to recognize that this is consistent with the previous installment, as it's the amount of space taken up by the entire Call of Duty application when the game is installed on the HDD/SDD.
In other words, this number includes the previous installments of the series that are installed with Black Ops 6 (MW2 and MW3, even if we have not purchased them; they may be able to be deleted from the disk later), which has already been confirmed by a well-known informant specializing in on the subject of CoD, CharlieINTEL.
