So by December 2021, at the latest, all Xbox 360 versions of Halo will no longer support online functions or updates. Sunsetting these online services will affect Xbox 360 versions of Halo: Reach, Halo 4, Halo 3, Halo 3: ODST, Halo: Combat Evolved Anniversary, Spartan Assault, and Halo Wars.

Microsoft Will Shut Down Halo Xbox 360 Online Services in December 2021. Maintaining the technologies that enable online services in games like Halo Reach, Halo 4, and others built for Xbox 360 takes more and more time every year, which takes resources away from creating and maintaining newer games.
