Bungie’s Marathon Loses Game Director Joe Ziegler in Major Leadership Change

Bungie’s Marathon loses game director Joe Ziegler as Del Chafe III takes charge.

Marathon has been live since March 5, 2026, and Bungie is already changing the person responsible for steering its post-launch future. Joe Ziegler, the game director who became the public face of Bungie’s extraction shooter, says July 17 (today) is his final day at the studio.

The timing lands in the middle of Marathon’s second season. Season 2 began on June 2 with the game’s first seasonal reset, while a mid-season update scheduled for July 21 will add the experimental Vault Breaker PvE mode. Ziegler had also outlined plans covering progression, Duos, matchmaking changes, and content running into 2027. The person explaining the roadmap is now leaving before several parts of it arrive.

New details from Ziegler now confirm who will take control.

Bungie’s Marathon Changes Game Directors as Joe Ziegler Leaves

Ziegler announced earlier today on X, that it was his final day at Bungie. Del Chafe III is taking over as Marathon’s game director and will lead the project alongside creative director Julia Nardin. According to Ziegler, both Chafe and Nardin were already working in major leadership roles on the team before the handoff.

Here’s the full statement from Ziegler:

“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 Nardin.

“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. I’m proud of them and I’m excited to see them helm the future of this crazy little world we’ve created together. As for me, I’ll be heading to something new, somewhere else, and will update you on where and what soon.

“I just want to say a deeply heartfelt thank you to all of you for supporting me and Marathon in our windy mission to bring a dark and terrifying space survival frontier to your screen. The mission will continue in new and surprising ways so stay tuned for what this team has in store for you! It’s been a pleasure seeing all the stories you’ve created, all the clever ways you’ve found ways to murder robots and one another.

“Hopefully as I move onto new things, you’ll join me for those adventures as well. Much love to the Marathon community and to all my friends and colleagues at Bungie. May we cross paths again. Keep it weird, keep it real <3.”

Ziegler didn’t name his next employer or project. He said he is moving somewhere new and plans to share more information later. His message was warm toward Bungie and the Marathon team, but the departure leaves a direct concern over how much of his existing plan will carry forward under new leadership.

Chafe’s promotion points toward continuity rather than another reset. Bungie’s current Marathon credits list him as assistant game director, while Nardin is listed as creative director, so neither is being dropped into the project cold.

It’s also hard not to talk about the massive round of layoffs that just hit Bungie last month, affecting the majority of the Destiny and some Marathon staffers as well.

Does Joe Ziegler’s exit make you less confident in Marathon’s next seasons, or does the internal promotion ease the concern? Let us know in the comments.
