By 13 January 2022, the servers of the Xbox 360 version of Halo will shut down. As a result, the games’ online services will no longer be accessible.
Halo Support stated on the tweet.
“In January, we will be sunsetting Halo Xbox 360 online services. The affected games will remain playable indefinitely, but some experiences will be impacted.”
There’s a chart on Halo Support official site showing the impacted features by the shutdown:
The support site also provides detailed information about the features that remain available after the shutdown:
Halo: Reach – Campaign, Firefight, Custom games, Forge, Splitscreen, Local Area Networking (LAN), Online squads, support will vary for Achievements
Halo 4 – Campaign, Spartan ops, Custom games, Forge, Splitscreen, LAN, Online squads, support will vary for Achievements.
Halo 3 – Campaign, Custom games, Forge, Splitscreen, LAN, Online squads, Service record, Player customization, support will vary for Achievements.
Halo 3: ODST – Campaign, Firefight, Splitscreen, LAN, Online squads, Service record, and Player customization.
Halo: CE Anniversary – Campaign, Splitscreen and LAN
Halo: Spartan Assault – Campaign, Online Squads, and Matchmaking
Halo Wars – Campaign, Online Squads, and Matchmaking
Some players criticize the shutdown because of the ongoing matchmaking issue in Halo 3, Halo: Reach, Halo 4, and Halo Wars.
One of the players complained about the matchmaking issue on the tweet. Suggesting to fix the servers instead of shutting down:
OK, but the past several days/couple weeks, matchmaking for Halo 3, Reach, 4, and Wars haven’t been working at all.
If the games need to be shut down, that sucks. However in the meantime, the servers need to be fixed so that people can play one last time and get achievements.
Even if you play these games on newer consoles through backward compatibility features, the shutdown still affects the game, because these games use the same server as the Xbox 360 versions.
However, Halo: The Master Chief Collection (2014) remains unaffected by the shutdown, because it uses different servers.
