What the Call of Duty: Black Ops III install size means in practice
The PC version is the largest listed build of Call of Duty: Black Ops III at 100.0 GB. Store listings show the size of the installed package, not the download; the transfer itself is usually 10–30 % smaller because the package is compressed on the way and unpacked on the console. Patches are added on top of the listed figure, so a game that has been out for a year commonly sits a few gigabytes above the number on its store page.
Call of Duty: Black Ops III is developed by Treyarch and published by Activision. Genre: Shooter, Adventure. Platforms: PC, PS4, Xbox One.
Against the rest of the database, Call of Duty: Black Ops III at 100.0 GB sits above the average install of 43.0 GB across 446 games; 53 of them are larger. Within its genre the average is 43.9 GB, which puts Call of Duty: Black Ops III on the heavy side for a shooter of its generation. On a launch PS5 with 667 GB usable it takes 15 percent of the free space; on a 2 TB expansion drive about 5 percent. Deleting it frees exactly the listed figure plus any patches installed since the store listing was checked, and the saves stay.
To check several games against one drive, the storage planner uses the same figures. For the drive itself, the PS5 SSD checker lists which M.2 drives meet Sony's requirements.
