Treyarch thanked their optimization for the day one experience to allow a manageable download in todays AAA market. It simply says that the day-one version of Black Ops 4 will be roughly 55GB in size with the game and all its various game modes playable after it's been completely downloaded.
Call of Duty: Black Ops 4 is out this week, bringing the anticipated sequel's nearly entirely multiplayer shenanigans to PC, PS4 and Xbox One.
The day one patch has become such an issue that United Kingdom shops have been given permission to sell the game a day early, so that everyone has a chance to download the update in a reasonable amount of time.
The massive day one patch is only for people who have pre-ordered the physical editions of Call of Duty: Black Ops 4 on consoles, but it's required so that you'll be able to play all the modes in the game.
According to the post "players should have 112 GB of free hard drive space" in order to begin the install process of Black Ops 4 on PS4.
The news comes from a post over on Activision's installation and setup pages for Black Ops 4. In order to play Blackout before the full installation is complete, select "Update to Latest Version" when the prompt appears. If you're among the many gamers eagerly awaiting your annual hit of Call of Duty action, then this would be the ideal time to free up a little room on your hard drive, as Activision has just announced the the size of the upcoming game's day 1 patch.
As for the file size, while the back of the cover lists 100 GB as the required hard disk space, the official PlayStation Store and Xbox Live Store have listed the file size as 42 GB to 48 GB respectively. The patch itself will be approximately 50 GB. While GAME's move is considerate, it comes because retail chains tend to demand that physical versions launch alongside their digital counterparts.
Before playing for the first time, players will need to download and install a day one update for Call of Duty: Black Ops 4.
