https://www.gamespot.com/articles/halo-5-update-coming-today-adds-xbox-one-x-support/1100-6454578/ >Halo 5: Guardians might be more than two years old now, but Microsoft and developer 343 Industries are not finished yet supporting the Xbox One game. A big new update is coming out today, November 2, adding Xbox One X support, new game modes, and making significant and potentially controversial changes to weapon balance. >The update adds 4K UHD support on Xbox One X, though that won't matter much to the general population as the Xbox One X doesn't release until November 7. 343 says the game will look "better than ever" on Xbox One X thanks to the console's beefed-up horsepower. As for the new game modes, Oddball and Oddball FFA (with new medals, too) are now in the hopper. They were in the game earlier, but were later removed.
