Halo has been struggling for decades. Not dying, but certainly struggling. And one of the clear reasons for the franchise's fall off since Halo 3 is that Xbox has been losing the console war.

Microsoft is moving its Halo development to Unreal Engine 5, after more than a year of rumors of an engine switch following a leadership overhaul at 343 Industries, layoffs, and other changes. 343 Industries is now becoming Halo Studios as part of this engine change announcement, hoping to mark a new chapter in the history of Halo.
