Activision has explained the large file sizes for Call of Duty Modern Warfare 3, which can exceed 200GB on consoles and PC due to a variety of content install packs, including Warzone files.

The Modern Warfare 3 campaign early access began on November 2, 2023, and players have reported a total Call of Duty install size of 234.9GB on PlayStation 5. This install appears to include Modern Warfare 2, now Call of Duty HQ, as well as Modern Warfare 3's campaign. It does not include other unreleased parts of Modern Warfare 3, such as Multiplayer and Zombies.

Activision issued a statement explaining that the increased file size is due to the following factors:

  • Increased amount of content available on release day, including open world Zombies
  • Support for item carry forward from Modern Warfare 2
  • Map files for current Call of Duty: Warzone

Activision also noted that players can reduce the install footprint by uninstalling specific content they're not playing.

Call of Duty players are used to large file sizes for the shooter series, but it seems Modern Warfare 3's unique launch has increased the load. Modern Warfare 3 is the first Call of Duty game to launch following Microsoft's $69 billion buyout of Activision Blizzard.

The Modern Warfare 3 campaign was developed by Sledgehammer Games in partnership with Infinity Ward, and is the direct sequel to last year's Modern Warfare 2. It includes 15 missions, each of which rewards players with items upon completion. These rewards can be used across Multiplayer, Zombies, and Warzone.

Modern Warfare 3 launches proper November 10, 2023.
