Modern Warfare 4 beta breaks tradition with full campaign mission

Activision has revealed extensive details about the upcoming Call of Duty: Modern Warfare 4 beta, marking a significant departure from previous franchise entries. The announcement, made via the official Call of Duty X account, detailed a two-session beta structure that includes unprecedented content. The first session runs from August 21st to August 25th and is exclusive to players who pre-ordered the game across PC, PS5, and Xbox Series X/S platforms. This early access period features the Entrenched campaign mission, which was recently showcased in a vignette, alongside five 6v6 multiplayer maps: Rooftops, Silkworm, Transit 213, Cachette, and Lotus. Players can experience traditional modes like Team Deathmatch, Domination, Hardpoint, Kill Confirmed, and Search & Destroy, plus the new Inflation game mode and the recently revealed Kill Block mode in both 3v3 and 10v10 variants.

The second session, running from August 28th to September 1st, opens to all players and adds the Nintendo Switch 2 platform, representing another first for the Call of Duty franchise. This open beta expands the content significantly with the addition of Ground War, the combined arms mode that originated in the 2019 Modern Warfare reboot. Two Ground War maps are included: Imjin Farmland and Wolves Stadium. The inclusion of campaign content in a beta test signals a strategic shift by Activision to boost single-player engagement, as historically only a small percentage of the player base completes the campaign mode. The company is also bringing back campaign early access, a feature absent from recent Call of Duty titles.

The beta's structure reveals a carefully planned content rollout designed to maintain player interest across both weekends. The first session establishes the core multiplayer experience with smaller-scale maps and modes, while the second weekend introduces larger-scale warfare through Ground War. The addition of Nintendo Switch 2 support in the open beta represents a significant platform expansion for the franchise. The timing of the beta, occurring roughly two months before the full game's October 23rd release, provides Activision with valuable server stress testing and gameplay feedback while building pre-release hype.

The broader context includes the upcoming Call of Duty: Next event, which will be entirely remote this year and will feature a first look at the Zodiac Warzone map. Questions remain about whether the updated free-to-play battle royale mode will launch alongside Modern Warfare 4 in October or later in the year. The beta's comprehensive content offering, spanning campaign, traditional multiplayer, and large-scale Ground War modes, represents Activision's most ambitious pre-release testing phase for the franchise. This approach may reflect lessons learned from previous launches and a desire to ensure technical stability across an expanded range of platforms, including the newly added Nintendo Switch 2.
