Halo’s franchise development director has elaborated on what is in store for Halo: The Master Chief Collection, whose multiplayer 343 Industries will attempt to fix — three years after its launch — following the Xbox One X’s upcoming launch.

Halo: The Master Chief Collection will be getting enhancements for the Xbox One X edition, but Frank O’Connor stressed that the real reason that 343 was revisiting the beleaguered game is because three years of changes to the Xbox operating system and networking provided that opening. “In terms of chicken/egg scenarios, fixing the existing ‘vanilla’ Xbox One MCC was the Chicken that laid the Xbox One X enhanced version egg,” he wrote in a blog post.
