Preload Windows and storage requirements
Preloading for PC players begins on Thursday, October 15, 2026, rolling out globally across key time zones: 9:00 AM PT, 12:00 PM EDT, 5:00 PM BST, 6:00 PM CEST, and 3:00 AM AEDT on Friday, October 16.
Official system requirements confirm that the PC version requires an SSD with at least 115GB of free space at launch, though future post-launch updates will demand additional capacity.
Console preload dates and exact file sizes for PS5, Xbox Series X/S, and Nintendo Switch 2 have not yet been finalised. In terms of platform availability, Modern Warfare 4 represents a complete transition to current-generation systems, launching on PC, PlayStation 5, Xbox Series X/S, and Nintendo Switch 2 while entirely dropping support for PlayStation 4 and Xbox One.
The game will not be available on any tier of Xbox Game Pass or PC Game Pass at launch, with inclusion planned for select tiers at an unannounced future date. Digital purchases on Xbox platforms do, however, support Xbox Play Anywhere across Xbox Series X/S and PC.
