New Halo Game Reportedly in Development Using Unreal Engine 5

Evidence from LinkedIn profiles of 343 Industries employees suggests work on the unannounced game began as early as April 2022.

343 Industries, the studio behind the Halo franchise, is reportedly developing a new installment of the game using Unreal Engine 5, according to rumors and LinkedIn updates from former and current employees.
Former Art Director at 343 Industries, Justin Dinges, updated his LinkedIn profile to reflect that he worked on the next 'unannounced' Halo release between April 2022 and March 2023.
Current 343 Industries Senior Character Systems Designer Ian Slutz has been working with Unreal Engine 5, according to his LinkedIn profile.
The switch to Unreal Engine 5 for the next Halo game would mark a departure from the use of Halo's Slipspace Engine.
The new Halo game is likely still years away from release.
