The short version

Call of Duty: Modern Warfare 4 was announced on May 28, 2026 and launches on October 23, 2026 across PlayStation 5, Xbox Series X|S, PC and - for the first time in the series - Nintendo Switch 2. An open beta is confirmed, with pre-order buyers getting early access before it opens to everyone.

The campaign is a darker, modern-day story built around a full-scale invasion of South Korea. Young Mazino (Beef, The Last of Us) leads it as Private Park, a green conscript soldier. This hub tracks the dates, editions and details that matter as Activision rolls them out - and flags clearly what is still unconfirmed.
