While Call of Duty: Black Ops 4 is approximately 55 GB, Activision recommends you have 112 GB of hard drive space available. Why? Well, because the day one update is “roughly 50 GB,” as clarified in their FAQ section.
Here’s the official information that lets you know exactly how big Call of Duty: Black Ops 4 will be after you finish all of the updates.
Installing Call of Duty: Black Ops 4 from a PlayStation 4 disc
Before playing for the first time, players will need to download and install a day one update for Call of Duty: Black Ops 4. This update must be installed completely in order to access Multiplayer, Zombies, and Specialist Headquarters. Blackout is fully playable once installation is about 30% complete (approximately 16-20 GB).
For an optimized download experience, players should have 112 GB of free hard drive space—note that this is not the size of the download, it is the amount of space required to complete the installation process. The final installation footprint will be approximately 55 GB. In order to play Blackout before the full installation is complete, select “Update to Latest Version” when the prompt appears.
The day one update package is roughly 50 GB. Download speeds may vary based on region, platform, connection type, and the speed of your internet connection.
This confirms the earlier leak claiming you need over 100 GB for Call of Duty: Black Ops 4. In terms of semantics, the game is 55GB, but once you add in the mandatory day one update, it explains why Activision says you should have “112 GB of free hard drive space.”
The good news is, you can play Blackout, Call of Duty: Black Ops 4‘s battle royale mode, once 30% of the game has been installed. That gives you something to do while you wait for the rest of the game to download.
