Treyarch Leadership Change
Mark Gordon Retires as Treyarch Studio Head, New Co-Leaders Named Amid Xbox Changes
Key Points
Treyarch’s announcement quoted directly that Gordon is retiring “to focus on his next chapter,” adding, “We’re incredibly grateful to Mark for his steady guidance and deep care for the studio, its culture, and its people.”
Beyond the Black Ops-era legacy described in the summary, Treyarch’s message (as reported) tied Gordon to a wider set of releases: “Call of Duty 2: Big Red One and Call of Duty 3, to World at War and the entirety of the Black Ops series.”
Reporting also says Gordon oversaw Treyarch through cross-studio/co-development work, specifically noting he handled “various co-development projects like Modern Warfare 3,” reflecting how Treyarch’s role extends beyond just standalone Black Ops releases.
One report flags Treyarch’s involvement in upcoming non-Black-Ops development: it is listed as a contributing developer on this year’s “upcoming Call of Duty: Modern Warfare 4 from Infinity Ward.”
The leadership change is framed alongside other Xbox studio shakeups: the article notes “all-but-confirmed closure” of Compulsion Games and the potential shuttering of Double Fine and Ninja Theory, plus warns that “upcoming layoffs” could still affect Treyarch even if it’s unlikely to be shut down.
Treyarch studio head Mark Gordon is retiring after 22 years at the Call of Duty developer, the studio announced on June 15. Gordon joined in 2004 as Chief Technology Officer and spent a decade leading the studio through the entire Black Ops era. IGN reported the news was shared on Treyarch's social media platforms.
Kevin Hendrickson and Yale Miller will replace him as co-studio heads, both promoted from within. The announcement landed the same day Ninja Theory was confirmed closed — part of a sweeping Xbox restructuring that is reshaping Microsoft's entire first-party gaming operation, according to WCCFtech.
Gordon Shaped Call of Duty Across Two Decades
Gordon's career at Treyarch spanned releases from Call of Duty 2: Big Red One and Call of Duty 3 all the way through the entirety of the Black Ops series. IGN noted he also oversaw co-development work on titles outside the Black Ops line, including Modern Warfare 3. Treyarch's official statement called his impact wide and lasting.
Treyarch said Gordon is leaving "to focus on his next chapter." The studio added: "We're incredibly grateful to Mark for his steady guidance and deep care for the studio, its culture, and its people." The most recent entry he oversaw, Call of Duty: Black Ops 7, launched in November 2025, according to Newsy Today.
Two Internal Veterans Step Up as Co-Heads
Hendrickson has served as Treyarch's COO since 2022. Before that, he was an Activision VP who oversaw production for the full Call of Duty franchise. Miller joined Treyarch in 2017 and has been Director of Production since 2020. Both are long-tenured Call of Duty veterans, according to WCCFtech.
The co-studio head model is designed to keep Treyarch's culture intact during a period of major change. Game Rant reported the duo are expected to maintain the studio's creative direction while managing the pressures of large-scale, multi-studio AAA development.
Treyarch Shifts Into a Support Role for Modern Warfare 4
Treyarch's next project is not a new Black Ops game. Infinity Ward officially announced Call of Duty: Modern Warfare 4 on May 28, 2026, with an October 23 release date. Treyarch is listed as one of 10 contributing developers on the project, alongside Sledgehammer Games and Raven Software, per OpenCritic.
This marks a shift for Treyarch — from a lead studio running its own franchise cycle to a support and co-development role. In another major change, Microsoft confirmed that Modern Warfare 4 will not be a day-one Game Pass title, ending the company's previous strategy of putting every first-party game on the subscription service at launch.
Gordon's Exit Is Part of a Broader Xbox Shake-Up
The Treyarch news broke on the same day Ninja Theory staff were told their studio was closing. On June 10, Xbox CEO Asha Sharma and CCO Matt Booty issued an "Xbox Reset" memo focused on financial sustainability and bigger IPs. Craig Duncan, the former head of Xbox Game Studios, had stepped down just days before, according to WCCFtech.
Compulsion Games and Double Fine are reportedly in talks to buy back their independence to avoid closure, per Game Rant. Treyarch is considered safe because Call of Duty generates massive revenue. But OpenCritic warned that upcoming layoffs could still touch the studio even if a full shutdown is unlikely.
