A former 343 Industries developer has seemingly confirmed that the next Halo game, which has yet to be officially announced, has been in development since at least April 2022.
As spotted by Idle Sloth on Twitter, former 343 art director Justin Dinges updated his LinkedIn profile to reflect that he had "worked on Halo's next unannounced release" from April 2022 to March 2023, when he left the studio to join Lost Boys Interactive.
