343 Industries head Dan Ayoub, who’s been with the series since Halo: Reach, has left to join Microsoft’s Mixed Reality team.

In a statement from 343 Industries on his departure, the studio said that, “Although Dan will be staying in the Microsoft family, and won’t be heading too far, our 343 family will miss his wit, wisdom and effort throughout the years. But Halo Wars 2 and its forthcoming DLC are in the safe hands of Dan’s team, with some wonderful DLC and other surprises still to come.”

“Over the years, Dan has helped us work with amazing studios and partners from literally every corner of the globe. They, like us are going to miss him, and Dan wanted us to express his thanks to both those partners, and to all the Halo fans and community who’ve been the fuel and fire that have ignited his passion and ambition, throughout the years.”

How will that influence future Halo games, especially when 343 Industries has admitted to narrative problems in Halo 5: Guardians? Let us know your thoughts in the comments.
