Activision has said that players with a 500 GB PlayStation 4 may "need to make room" if they wish to have the fully updated versions of Call of Duty Black Ops Cold War and Modern Warfare/Warzone present on one system.|
In a post on the Call of Duty blog, the franchise publisher wrote: "Those who own a standard PlayStation 4 with a default hard drive of 500 GB may need to make room if they have the full versions of Modern Warfare®/Warzone and Black Ops Cold War with all modes and packs installed. Should you have both games installed and have kept up to date with updates, you may need to delete some unused Game Content to have a successful download and install of the [latest] Warzone patch."
It's common knowledge that Activision's latest Call of Duty games take up swathes of storage, but it seems that they may be stretched beyond the capacity of a base PS4 as they receive more updates. It may be that, without compression, external storage may become the only way to have the full Call of Duty package on one console for some players.
