Co-founder and general manager of Halo studio departing to attend to a "family medical issue"

Corporate vice president of Xbox Game Studios and head of 343 Industries Bonnie Ross has announced her departure from the two firms.

In a post shared to Twitter, Ross said she had "hoped to stay with Halo until we released the winter update," but added that she'll be leaving and "attended to a family medical issue."

Ross added: "It has been an honour to serve alongside the team for the last 14 years and to be a part of a universe that I love."

While Ross' statement only mentions 343, WindowsCentral reports that she is also leaving her post at Xbox.

"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," a quote shared to WindowsCentral reads.

"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."

The outlet reports that 343 Industries head of production Pierre Hinze will step into the role of studio head, effective immediately.
