Microsoft has officially transferred the lead development of the next mainline Halo title to Activision, marking a fundamental shift in how Xbox manages its flagship franchise. The move effectively ends Halo Studios’ (formerly 343 Industries) tenure as the primary architect of the series, following a series of internal restructurings and leadership changes at Microsoft’s gaming division.
Activision is currently assembling a “purpose-built team” specifically for the project. According to Activision President Rob Kostich, this new group will operate independently from the studio’s annual Call of Duty development cycle. While Halo Studios will remain involved in the franchise, its role has been reduced to that of a support studio, assisting Activision’s new team rather than directing the creative vision.

The transition follows a period of significant upheaval within Xbox Game Studios. In an internal memo titled “Continuing Our Reset,” Xbox Chief Content Officer Matt Booty confirmed that 268 employees were laid off, primarily affecting the team at Halo Studios. This restructuring coincides with a broader consolidation effort that has placed veteran studios like Rare and World’s Edge under the Activision banner for oversight.
A New Custodian for Master Chief
The decision to move Halo away from its dedicated studio appears to be a direct consequence of recent performance metrics. Reports indicate that the July 2026 release of the Halo: Campaign Evolved remake—a campaign-only title that launched without a multiplayer component—was a commercial disappointment. This outcome likely accelerated Microsoft’s plans to leverage Activision’s infrastructure and experience with high-stakes first-person shooters.
The news has caught even the franchise’s original creators by surprise. Marcus Lehto, co-creator of the Halo universe, took to social media to clarify that he is not involved in the new project. Lehto expressed shock at the effective end of Halo Studios’ lead status, a sentiment shared by many longtime fans who viewed the studio as the permanent successor to Bungie.
This seismic Xbox Studios shakeup extends beyond the Halo franchise.
The Technical Path Forward
The technical foundation of the next Halo remains a point of industry speculation. While Halo Studios had previously announced a shift to Unreal Engine 5 for future projects, Activision’s involvement raises questions about whether the franchise will instead adopt the proprietary engine used for the Call of Duty series. Activision has not yet confirmed which technology will power the new team’s efforts.
As Activision takes the lead, the primary challenge will be balancing the traditional identity of Halo with the modern live-service demands that Activision has mastered with other properties. For now, Halo Studios’ transition to a support role signifies the most significant change in the brand’s history since Bungie’s departure in 2007.
