Activision has slated the Call of Duty Modern Warfare 4 open beta for a window spanning late August through mid‑September 2026, roughly a month ahead of the title’s slated worldwide launch on 23 October 2026.
Beta schedule and participation tiers
The beta will roll out in two phases. An Early Access window opens first for players who pre‑order any edition of Modern Warfare 4, followed by a fully public session that anyone can join at no cost. Historically, Activision guarantees a minimum of two days for each weekend‑long test, typically running from Friday through Monday.
Steps to claim Early Access or join the free public beta
- Choose between paying for Early Access (by pre‑ordering) or waiting for the free public weekend.
- Secure a pre‑order of either the Standard or Premium edition; physical copies include a 13‑digit beta code on the receipt or in a confirmation email.
- Visit the official Call of Duty beta redemption portal and enter the code to register your account.
- Monitor Activision’s announcements for the exact download window.
- Navigate to the PlayStation 5, Xbox Series X|S, or PC storefront (Steam / Battle.net) and pull the beta client.
- Launch the client and dive into Modern Warfare 4’s multiplayer test environment.
What the beta will showcase
Players will experience the newly introduced movement mechanics that promise a refreshed tactical feel. In addition, the experimental “Kill Block” map will be available for early testing, offering a glimpse of future multiplayer environments. The beta is limited to current‑generation hardware—PS5, Xbox Series X|S, and PC—so legacy consoles will not receive access.
With the open beta window narrowing, pre‑ordering now secures early hands‑on time, while the free weekend remains open for all who wish to sample the upcoming experience before the official October release.
