Halo Infinite is very much the center of attention for the folks at 343 Industries now, and as a byproduct of that, Halo: The Master Chief Collection has been shifted to the sidelines.
Alongside that, it seems like 343 Industries is looking to make other significant changes to the game as well.
Halo: The Master Chief Collection is available on Xbox Series X/S, Xbox One, and PC.
Either way, it sounds like 343 Industries will be ready to share concrete details on the matter sooner rather than later, so stay tuned for those details.
