Microsoft and 343 Industries have shut down the matchmaking multiplayer servers for the mainline Xbox 360-era Halo games, including Halo 3, Halo: Reach, and Halo 4 (as well as Firefight matchmaking for Halo 3: ODST). Additionally, a number of other services have been sunset as well, including File Share in all of the aforementioned games as well as Service Records, Player Customization, and Challenges in Halo: Reach and Halo 4.
In the days and hours leading up to the closure of the servers, many Halo fans flocked back to these titles and entered matchmaking for one last time. Some helped fellow fans get their final missing achievements, while others simply made truces with the enemy and posed for large group screenshots. Many also filled Custom Games lobbies and played classic custom Halo modes like Duck Hunt (thankfully, Custom Games and non-matchmade Firefight lobbies are still available since they use a peer-to-peer connection).
