We’ve learned the creative director for Halo Infinite has resigned from the studio, roughly a year ahead of the game’s tentative launch.

Longo has been at 343 Industries since 2013, where he served as creative director on Halo 5: Guardians, and prior to his tenure at 343, creative director for Crystal Dynamic’s Tomb Raider reboot.

Microsoft confirmed Longo’s departure in a statement to Kotaku, and noted his leave comes alongside a changing of leadership.

“Roles and responsibilities of various team members regularly evolve to meet the needs of a game, throughout development,” Microsoft said, “We have recently had two changes to the Halo Infinite development team.” Longo’s departure from 343 accounts for one of those, while the other sees executive producer Mary Olson stepping into the lead producer role to head Halo Infinite’s campaign team.

“The overall creative vision and production of the game,” Microsoft continued, “remains led by Chris Lee, studio head of Halo Infinite.”

Microsoft closed by thanking Longo for “his many contributions to our games, our studio and the Halo universe. We wish Tim nothing but the best in his future endeavours.”

The changing of leadership won’t affect Halo Infinite’s release, which is tentatively set for “holiday 2020” on Windows PC, Xbox One, and Microsoft’s new console, codenamed Project Scarlett.
