Modern Warfare 4 Beta Adds Single-Player Mission for the First Time

For the first time in the franchise's long-running beta history, Call of Duty: Modern Warfare 4 will allow players to experience a single-player campaign mission ahead of launch. Xbox has officially announced that this month's pre-release beta will feature "Entrenched", a story mission available to all beta participants, marking a notable shift from the series' traditional multiplayer-only test approach.

Beta Structure and Access

The Modern Warfare 4 early access beta is scheduled to run from 21 to 25 August 2026, following the Call of Duty Next event. This initial phase is open to players who have pre-ordered the game on PC, PlayStation 5, or Xbox Series X | S. During this period, participants will have access to a selection of multiplayer maps-Rooftops, Silkworm, Transit 213, Cachette, Lotus, and Kill Block-across multiple modes, as well as the new single-player mission.

The open beta will follow from 28 August to 1 September, expanding access to all players, including those on Nintendo Switch 2. While "Entrenched" remains available throughout both beta periods, the multiplayer map rotation will change, with the Lotus map replaced by Lithium for the open weekend. The second weekend will also see the debut of the new Zodiac Warzone Resurgence map, broadening the test's scope for both competitive and narrative content.

What the Beta Offers

Modern Warfare 4's beta is designed to provide early feedback on both multiplayer and single-player content. The inclusion of a campaign mission is a first for the series, which has previously limited pre-release access to multiplayer gameplay. Xbox's announcement was accompanied by a short gameplay teaser for "Entrenched", offering a glimpse of the mission's setting and objectives, though full details remain under wraps until the beta goes live.

Players interested in multiplayer will still find the usual suite of modes and maps, with the addition of the Zodiac Warzone Resurgence map in the second weekend. The beta's structure is intended to encourage both competitive and narrative-focused players to participate, with content varying between the early access and open periods. For those tracking major upcoming releases, this approach follows a trend of expanding beta content, as seen with other high-profile franchises detailed in NGB's coverage of future blockbuster release windows.

Release Date and Platform Details

Call of Duty: Modern Warfare 4 is set to launch on 23 October 2026 for PC, PlayStation 5, and Xbox Series X | S. The beta's open phase will also support Nintendo Switch 2, marking the first time the series has offered a campaign mission preview across such a broad range of platforms. Access to the early beta remains tied to pre-orders, while the open beta is free to all supported platforms during its scheduled window. Xbox Game Pass members are reminded that Modern Warfare 4 will not be included in the subscription at launch and must be purchased separately for day-one access.

Official gameplay footage released so far has focused on the "Entrenched" mission and the new Warzone map, but no independent technical analysis is yet available. As with previous betas, performance, stability, and content may differ from the final release, and players should expect further updates as launch approaches.

When a beta includes both multiplayer and single-player content, it serves as a test environment for gameplay systems, network stability, and player feedback ahead of full release. Betas are typically based on non-final builds, meaning performance, visuals, and content may change before launch. Access conditions, such as pre-order requirements or open periods, are set by the publisher to manage server load and gather a broad range of player data. Players should treat beta experiences as indicative rather than definitive, with the understanding that technical issues and content adjustments are common before the retail version arrives.
