The listing, visible on Nintendo's storefront, provides an early look at storage requirements for players planning to buy on Nintendo Switch 2 or via the eShop.
Call of Duty: Modern Warfare 4 is published by Activision and will release on Nintendo Switch 2 and other formats on October 16, 2026.
The eShop entry explicitly lists the 84.9GB file size, a figure that underscores how modern AAA multiplatform releases increasingly demand significant local storage.
Recent Call of Duty entries on PlayStation 5 and Xbox Series X|S have likewise carried large install footprints, and the Switch 2 listing places Modern Warfare 4 squarely in that trend.
Player reaction was immediate on the game's storefront comment thread and in social channels.
Many users noted the size was substantial for a Switch platform release.
Some commenters observed that the Switch 2 build appears considerably smaller than reported sizes for the game on other consoles, suggesting platform-specific packaging or asset differences.
Others drew comparisons to large modern ports, citing titles like Final Fantasy VII Remake and MMORPG installations that can exceed 100GB to provide context for contemporary AAA install sizes.
From a practical standpoint, an 84.9GB install has clear implications for Switch 2 owners: ensure available internal storage or plan to purchase additional microSD capacity before download.
Nintendo has traditionally sold Nintendo Switch consoles with modest onboard space, and while Switch 2 models vary by configuration, large multiplatform releases will routinely require either free internal storage or high-capacity microSD cards.
With the October 16, 2026 release date confirmed on the eShop listing, prospective buyers should watch for pre-load windows and any post-launch patches that could alter final on-disk size.
For now, the 84.9GB figure is the official listing on Nintendo's storefront and is the best available guidance for Switch 2 users planning to purchase Call of Duty: Modern Warfare 4 on launch day.
