'Call of Duty: Black Ops Cold War' and 'Modern Warfare' combined will exceed 320 GB on next-gen systems

Moreover, "Cold War," "Modern Warfare" and "Warzone" will continue to feature live service elements, per a blog posted Thursday, with a new battlepass featuring "Cold War" coming in December. More content likely means more required storage space, and while Activision's plan allows players to progress in the battlepass and earn Call of Duty XP regardless of which of the three versions they're playing, the sheer volume of required disk space may push players to choose their favorite version of the franchise, limit space for non-COD games or modify their usual gaming behaviors in other ways.
