Joe Ziegler, the game director of Marathon, has left Bungie and the game effective immediately, just four months after its release. Del Chafe III will take over Ziegler's role, working with creative director Julia Nardin. Ziegler expressed gratitude to fans in a message on X and hinted at new opportunities ahead. Marathon's player counts on Steam have not matched those of Destiny 2, and the game faces challenges in establishing itself in a competitive market. Ziegler joined Bungie in 2022 and became the leader of Marathon two years ago. His departure, along with that of Lars Bakken, former design lead for Marathon, raises concerns about Bungie's stability and future direction.
