Microsoft Puts Activision in Charge of Halo, Sea of Thieves and Age of Empires
Microsoft has put Activision in charge of Halo, Sea of Thieves and Age of Empires under a restructuring of its Xbox studios announced Sept. 22, 2026. The plan eliminates around 268 Xbox roles in the near term. The Verge
That structure places three long-running franchises under one publishing organization, the group that funds, staffs, tests and ships games. Activision will take on Halo, Sea of Thieves and Age of Empires as part of the reorganization. The headcount impact is phased over time.
Halo and strategy franchises consolidate under Activision
The next flagship Halo installment, meaning the next major new release, will be developed by Activision instead of Halo Studios. Halo Studios will continue to support Halo Infinite and Halo: Campaign Evolved. The split separates ongoing updates and catalog support from new flagship development.
Activision's next Halo title will be led by a new purpose-built team separate from Call of Duty development. For engineers, that distinction matters. It implies separate staffing, separate production leadership and separate technical roadmaps, rather than rotation of existing Call of Duty teams onto Halo.
World's Edge, the studio behind Age of Empires, is joining Activision. The move places strategy development inside the same organization now responsible for Halo. Rare's UK team is joining the Activision side of Xbox as part of Activision taking control of Sea of Thieves. That puts a live-service multiplayer game, one that is updated continuously, and its studio team under Activision management.
Bethesda, racing and casual realignment
Obsidian is moving to Bethesda to work on a new Fallout title. The reassignment aligns an RPG, or role-playing game, studio with the Bethesda publishing group for that project. No release scope was detailed in the verified facts.
Turn 10 Studios and Playground Games are merging into a single studio focused on Forza Horizon and Fable. Two racing and open-world teams become one operating unit. The stated focus is Forza Horizon and Fable.
Microsoft is moving its casual games unit responsible for Solitaire, Mahjong and Minesweeper from Bethesda to King. That transfers lightweight, high-reach Windows and casual titles to the mobile-centric King organization. These are short-session card and puzzle games built for broad hardware coverage and ongoing live operations, or regular updates and support.
Headcount and timeline
Microsoft said 3,200 roles are set to be impacted by Xbox cuts over its 2027 financial year ending in June 2027. The 268 near-term cuts sit inside that larger phased total. Xbox Wire lists an Announcements article titled "Continuing Our Reset."
The reset follows months of overhaul signals. In June 2026, Microsoft's Xbox division was planning major job cuts for the next month, with Asha Sharma identified as the new chief executive officer of Xbox overseeing its 2026 overhaul. Bloomberg Xbox planned significant cuts to marketing and other budgets as part of its 2026 overhaul. Reuters
Earlier workforce actions provide context. Microsoft planned to cut 4,800 jobs in July 2026 including an overhaul of its Xbox unit. Reuters Microsoft cut 650 jobs in its Xbox games unit in September 2024. Prior reporting also listed Raven, Sledgehammer Games, Rare, ZeniMax Online Studios, Halo Studios, and King among groups impacted by Xbox cuts. Those earlier figures describe prior phases and reporting, not the current Sept. 22 plan.
The broader context here is consolidation around publishing owners rather than standalone studios. Halo, Sea of Thieves and Age of Empires gain a single accountable organization in Activision. Fallout development aligns Obsidian with Bethesda. Casual games align with King. Racing and Fable consolidate into one team.
In my view, the engineering logic is to reduce cross-publisher dependencies for build pipelines, the automated steps that turn code into a playable game, live-service tooling, QA or quality-assurance testing, and content cadence.
Worth flagging for readers is what changes in day-to-day development. A purpose-built Halo team inside Activision will need its own decisions on engine branches, asset pipelines for getting art into the game, multiplayer netcode that keeps online play smooth, anti-cheat, and content delivery. Continued support of Halo Infinite and Halo: Campaign Evolved by Halo Studios means two Halo codebases and live operations will run in parallel under different owners for a period. Merged racing and Fable work will require reconciliation of world-building tools and release schedules. Casual games moving to King will test how Windows-bundled titles integrate with mobile live-ops practices.
In my view, the opportunity if the consolidation holds is clearer ownership and faster iteration within each franchise lane. Shared publishing infrastructure can help with certification, platform integration, analytics and support. That does not remove creative or technical risk. It changes where integration work happens.
