Joe Ziegler, the game director for the extraction shooter Marathon, has announced his departure from Bungie. Leadership of Marathon has been handed to assistant game director Del Chafe III, four months after the launch of the game. His departure comes as Bungie continues to rebuild player confidence following Marathon’s difficult launch.

Hey everyone I’ve got a bit of an announcement to make. Today, Friday 7/17, will be my last day at Bungie and I’ll be 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…

Ziegler’s last day at Bungie was July 17th, a fact he announced on social media. In that statement, he thanked players for supporting the game, and stated that he would, “be heading to something new, somewhere else.” However, the post leaves this ambiguous, as the statement does not announce where his next destination is, or what motivated him to leave Bungie. Bungie has already transitioned leadership to Del Chafe III as the new game director. Chafe will also be joined by Julia Nardin, the game’s creative director, and will collaborate to lead the project in the future. Since Bungie immediately announced a successor, the transition appears to have been planned rather than an emergency leadership change.

The timing of this departure is notable, being so soon after the launch of the game. Marathon is still in its post-launch growth phase, the period during which live-service titles generally receive frequent content updates. Leadership during this vulnerable growth stage is crucial for the live-service game’s future success. This is further compounded by the fact that Ziegler isn’t the only member of Marathon‘s leadership that has left Bungie: art director Joseph Cross also left Bungie before the game’s launch. This means that Marathon has lost both its game director and art director within a year.

The departure of Marathon leadership also comes during a turbulent period for Bungie, as the company has experienced a period of restructuring. There have been multiple rounds of layoffs, leadership changes, and a broader strategic shift toward supporting Marathon alongside Destiny 2‘s evolving content model. As Bungie continues its own organizational restructuring, the Marathon team is also working to regain player confidence through future updates. With player engagement declining after launch, those future updates could play an important role in the game’s long-term success as a live-service title.
