Call of Duty Modern Warfare 4 Beta date: 2026 Schedule

The Call of Duty Modern Warfare 4 Beta date is divided into two scheduled participation windows in 2026. Beta Weekend 1 is reserved for qualifying pre-orders and pre-purchases, while Beta Weekend 2 opens access to all players on supported platforms without requiring a pre-order.

The official schedule lists the early access period from August 21 at 11:00 AM PT through August 25 at 10:00 AM PT. The open access period begins August 28 at 10:00 AM PT and ends September 1 at 10:00 AM PT. The beta is a limited-time test, so plan around the published windows rather than assuming access will remain available after the closing time.

The full game is scheduled to launch on October 23, 2026. Rewards earned during the beta are intended to become playable in Modern Warfare 4 when the full game launches, while rewards unlocked during the test are immediately available for use within the beta.

For the latest schedule wording and participation notes, use the official Call of Duty: Modern Warfare 4 Beta page.

The beta supports multiple platforms across both weekends, but the access rules are not identical. Early access codes are listed for Xbox Series X|S, PlayStation 5, PC Battle.net, Xbox on PC, and PC Steam. Weekend 2 expands participation to all listed platforms, including Nintendo Switch 2.

A digital pre-order or pre-purchase through a participating first-party or PC storefront automatically validates early access in most cases. Retail purchases generally use a 13-character beta code that must be redeemed through the official Call of Duty redemption page.

Nintendo Switch 2 pre-orders are scheduled to begin on August 26, 2026. Switch 2 players can enter the open beta during Weekend 2 beginning August 28, 2026, and the official information states that no pre-order is required for that weekend.

Participation can also depend on territory, retailer availability, internet access, and an online multiplayer subscription where applicable. These conditions may vary by platform and region, so review the current official terms before making a purchase decision.

Early access is primarily tied to a qualifying pre-order or pre-purchase. Digital purchases through the Microsoft Store, PlayStation Store, Battle.net, or Steam Store generally register the account automatically. Retail purchases from participating sellers usually provide a code on the receipt or through an email receipt.

Follow these steps to prepare for Beta Weekend 1:

A free Activision account is required for code redemption. New accounts must complete email verification before the redemption process can be finished. Tokens are scheduled to be distributed shortly after the early access preload starts on August 20, 2026, at 9:00 AM PT.

The Modern Warfare 4 Beta focuses on multiplayer content, with additional campaign and Warzone material planned across the test period. The announced multiplayer lineup includes core 6v6 maps and modes, plus Kill Block. Weekend 2 adds Ground War: Combat Outpost and the new Zodiac Resurgence map in Call of Duty: Warzone.

The single-player Campaign mission “Entrenched” is also included in the beta. Because content is distributed across the weekends, players who enter during Weekend 2 may see a broader selection than players who only join early access.

To make the most of the available test period, start with the core 6v6 modes and use the first matches to check controller, mouse, audio, and network settings. If you are joining during Weekend 2, reserve time for the newly introduced Ground War and Warzone content rather than spending the entire session in one mode.

The beta also provides an opportunity to earn in-game rewards. Those rewards are immediately usable during the beta and are planned for use in Modern Warfare 4 after the October 23, 2026 launch.
