A few days ago we learned of the improvements made to Halo 3 in Halo: The Master Chief Collection, and yesterday I had a chance to ask the good folks at 343 Industries about more details on the remaining two chapters (besides Halo 2: Anniversary, of which we have seen quite a lot).
The answer was quite simple. Halo 4 got pretty much the same treatment as Halo 3, with improved resolution and frame rate, and modernized lighting and shaders.
With Halo the remastered version Halo Anniversary was used as a base, and then the same treatment as Halo 3 and 4 was added on top of it, making it basically a remaster of a remaster.
We also learn that Kinect support was considered , but didn’t fit in the schedule. There simply wasn’t enough time, and in the end it worked well considering that the additional resources released by not using Kinect were redirected to help performance.
343 Industries also has no plans to add any Smartglass integration to the game.
