Bonnie Ross, the head of Halo developer 343 Industries, has announced her departure from 343 Industries and Microsoft. Head of production Pierre Hintze has been made 343's new studio head "effective immediately."

"While I had hoped to stay with Halo until we released the Winter Update, I am letting you know I will be leaving 343 and attending a family medical issue," Ross said.

"I am incredibly proud of the work everyone at 343 Industries has done with Halo Infinite, the Master Chief Collection, the Halo television series and so much more. "It has been an honour to serve alongside the team for the last 15 years and to be a part of a universe that I love."

Ross' statement only mentions that she's leaving 343 Industries, but in a statement shared with Windows Central, Microsoft says she's also leaving Microsoft. The statement also mentions that head of production Pierre Hintze is now 343's studio head.

"After more than 28 years in gaming at Microsoft, including 15 years leading 343 Industries and Halo through its most ambitious steps forward, Bonnie Ross will be leaving Microsoft and spending more time with her family."

We are thankful for her leadership of 343 during which the team launched Halo 4, Halo 5, Halo: The Master Chief Collection, the Halo television series, and Halo Infinite. We wish her all the best. Head of Production Pierre Hintze will become Studio Head effective immediately. The 343 team is hard at work shipping the Winter update, the biggest Halo Infinite update since launch."

Earlier this month, 343 Industries announced that Halo Infinite's campaign co-op had been delayed and split-screen co-op had been cancelled. Campaign co-op is now expected with Halo Infinite's Winter update in November, alongside Forge mode.
