Bungie has confirmed another major leadership change, as Marathon game director Joe Ziegler has announced his departure from the studio. The news comes just four months after the launch of Marathon and follows a turbulent year for Bungie that included layoffs, the end of Destiny 2 content development, and broader restructuring under Sony.
Despite the change in leadership, Bungie says development on Marathon will continue under experienced studio veterans as the game enters its next phase.
Joe Ziegler hands Marathon leadership to Bungie veterans
In a post shared on X, Ziegler confirmed that he is leaving Bungie and passing the role of game director to Del Chafe III, who will lead the project alongside Creative Director Julia Nardin.
“I’m passing the torch of Game Director to the very capable and amazing hands of Del Chafe III, who will guide the game forward alongside the Creative Director Julia Nardin.”
Ziegler praised both developers, noting that they had already been operating in leadership roles and were well prepared to guide Marathon into its next chapter.
“Both of them have been operating in a strong leadership capacity for the team and are ready to guide Marathon into the next chapter with an even better and brighter future.”
He added that he would soon reveal details about his next career move while thanking players for supporting Marathon and expressing confidence in the team’s future.

Leadership change follows a difficult year for Bungie
Ziegler joined Bungie after serving as game director for Valorant at Riot Games. In 2024, he replaced former Marathon director Christopher Barrett, whose departure led to a high-profile legal dispute with Bungie and Sony before both parties later reached a settlement.
His exit now comes during another challenging period for the studio. Earlier this year, Bungie confirmed that Destiny 2 would no longer receive major content updates, while Sony announced significant layoffs affecting much of the Destiny team and parts of the Marathon development team.
Marathon has also faced commercial challenges since launching in March. According to Steam Charts, the extraction shooter reached a peak of more than 77,000 concurrent players at launch but has since seen lower player activity. However, Sony has continued to express confidence in the game’s long-term potential.
During the company’s earnings briefing, Sony CFO Lin Tao said Marathon maintains strong player reception, pointing to its 82 Metacritic score, overwhelmingly positive Steam reviews, and healthy player retention. Tao added that Sony plans to improve the game’s performance through new content updates, gameplay improvements, and continued expansion of its player base.
Meanwhile, Bungie recently announced Vault Breaker, a limited-time roguelite PvE mode arriving during Season 2: Nightfall, with a full PvE mode planned for Season 3, signaling that development on Marathon remains active despite the studio’s ongoing changes.
