One of the longest-standing Halo developers--art director Nicolas Bouvier AKA "Sparth"--has left the Halo team and Microsoft entirely. Sparth said on Twitter that after nearly 14 years working on Halo, he has decided to leave to pursue other opportunities outside Microsoft and developer 343.

"It's been a hell of a ride, loved every minute of it," Sparth said. "Wishing the absolute best to 343, you guys are and always will be amazing."

Sparth started at Microsoft in 2009 and was the lead concept artist on Halo 4 and Halo 5. He then became art director, eventually working on Halo Infinite. In January 2022 he was promoted to Senior Art Director, a position he held for seven months until leaving the company this week.
