Today during a livestream event, Microsoft made some big announcements about the Halo franchise, including new Xbox One X patches and ongoing support for Halo 5. We already knew that Halo 5 will receive an Xbox One X update, and today developer 343 confirmed that Halo Wars 2 is also getting patched to unlock "visual upgrades" on the new console. Halo: The Master Chief Collection is also getting an Xbox One X update, while players can also expect updates that include bug fixes and improvements.

Overall, 343 wants to "bring [Halo: MCC] forward and modernize many of the game's systems to take advantage of Xbox platform advancements since its original launch." The game had its share of serious struggles at launch, so it's nice to see support continue in this way, years after release.
