Members of the newly-renamed Halo Studios explain why they are switching from the proprietary Slipspace Engine to Epic's Unreal Engine 5.

Halo is moving to Unreal Engine 5. Here’s the topline from 343 but…not 343, as along with this announcement is a rebrand to “Halo Studios”:

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.
