If you follow Call of Duty studio leadership, this is a notable shake-up: Treyarch’s long-serving studio head Mark Gordon has stepped down, and two veteran internal leaders are taking over. The timing also overlaps with broader Xbox studio departure and layoff rumors, so players may want to watch what changes next for Treyarch’s upcoming work.
What changed at Treyarch
Mark Gordon, a veteran Call of Duty developer and Treyarch studio head, has retired from the role after more than two decades with the company—22 years, per Treyarch’s official announcement on June 15, 2026. Treyarch’s post credits his tenure with work on major entries in the franchise, including Call of Duty 2: Big Red One (2005), World at War, and the full Black Ops series, which now culminates in Black Ops 7.
With Gordon stepping aside, Treyarch has named Kevin Hendrickson and Yale Miller—both described as having roughly a decade at the studio—as co-studio heads. Treyarch did not provide a detailed reason for the departure beyond Gordon’s stated intent to focus on his next chapter.
Who is affected and why the timing matters
Gordon’s exit comes at a sensitive moment for studios under Xbox’s umbrella. In the days following reports tied to Xbox restructuring—framed around anticipated layoffs across multiple departments—other longtime Xbox Game Studios personnel have also reportedly left their roles.
The source points to similar patterns of departures among veteran staff, and it also mentions that Xbox Game Studios head Craig Duncan and Chief of Staff Louise O’Connor have left their posts. Both had long tenures at Rare before moving to Xbox Game Studios.
While the source does not confirm specific outcomes for every team, it does describe a grim outlook for some smaller studios. Compulsion Games (South of Midnight) is described as potentially on track for closure or in discussions about its future, while Ninja Theory and Double Fine are also mentioned as possibly being on the table.
What comes next for Treyarch and Call of Duty
For Treyarch itself, leadership is the immediate story: Gordon is out, and Hendrickson and Miller are now co-leading. The source suggests that this could be a straightforward career transition, but it also raises the question of whether the broader industry environment is influencing internal plans.
It also frames the current franchise moment as complicated. Black Ops 7 is described as having underperformed with fans, though the title is still characterized as one of the most played games on consoles and PC.
With that context, players may want to pay attention to how Treyarch manages continuity after a long-term studio head’s departure—especially given the wider uncertainty described across Xbox-affiliated teams.
What players should know
- Treyarch’s long-serving studio head Mark Gordon has retired after 22 years; Kevin Hendrickson and Yale Miller become co-studio heads.
- Treyarch did not give a detailed cause for the change beyond Gordon wanting to focus on his next chapter.
- The announcement arrives amid reports of Xbox restructuring, layoffs, and additional veteran departures across Xbox Game Studios.
- Black Ops 7 is described as having underperformed with fans, even though it remains among the most played titles on consoles and PC.
Expert View
This looks like a leadership handoff rather than an announced creative reset: Treyarch is keeping internal veterans in charge, and the company’s message emphasizes Gordon’s retirement and next-step plans. Still, the broader backdrop—reported restructuring and departures across Xbox—makes the timing feel consequential. For fans, the practical takeaway is to monitor how Treyarch’s co-studio heads steer priorities after Black Ops 7, especially as uncertainty continues to ripple through multiple studios.
