Call of Duty: Black Ops 6 is currently listed with an approximate file size of 309.85 GB. The game will require the Call of Duty HQ launcher, which also houses Call of Duty: Warzone, Call of Duty: Modern Warfare 2, and Call of Duty: Modern Warfare 3. The inflated file size is how much space the game will require if all other elements of Black Ops 6 plus the previous games and Warzone are installed simultaneously. Players can opt to delete some segments of each Call of Duty game if they are not playing them. Activision has also confirmed that the file size will be reduced by launch.
