Bungie game director Joe Ziegler officially departed the studio on July 17, 2026, handing leadership of the Marathon project to assistant game director Del Chafe III and creative director Julia Nardin. This transition follows a period of significant restructuring at Bungie, which included approximately 300 layoffs—nearly 40 percent of the studio’s workforce—and a decline in Marathon’s player engagement, with recent Steam metrics showing a lowest all time peak of 2,030 concurrent users.
Leadership Transition Amid Studio Restructuring
Joe Ziegler’s exit marks a shift in the development trajectory for Marathon. In a post on X, Ziegler stated that Chafe, a 15-year veteran of the studio, is prepared to guide the extraction shooter into its next phase. Ziegler, who did not disclose his next destination but hinted at a new project at another studio, noted that the team’s mission remains ongoing.

This leadership change occurs in the wake of broader organizational instability. Following June layoffs, former general manager Scott Taylor was replaced by Joshua Deane, who currently serves as both the studio’s head of product and general manager. Additionally, Lars Bakken, who contributed to the studio for 20 years with credits including Halo 3, has departed the company.
Did you know?
The Marathon development team has seen significant turnover during a year that saw Bungie reduce its total headcount by nearly 40 percent, according to reports on the studio’s restructuring.
Market Performance and Future Projections
Marathon currently faces a challenging environment as it approaches its post-launch roadmap. Data from early July 2026 indicated a lowest all time peak of 2,030 players on Steam, a trend that has prompted concern regarding the game’s long-term retention. While Sony has maintained its commitment to the project, the studio is currently balancing the development of Marathon with the prototyping of its next internal title.
Observers are looking toward the fall for a potential shift in momentum. The studio plans to introduce a full-blown PvE mode, which is intended to broaden the game’s appeal and stabilize the player base.
