So clubs have just been introduced by Xbox! There are already several Halo Clubs! The official 343 Halo club is called (obviously) “Halo”. I also created a club for us waypointers called “Halo Waypoint Club”. There are a few other cool Halo clubs out there if you search for them!
Anyone is welcome to join the club i created: “Halo Waypoint Club”
For those who love classic Halo, such as playing customs on MCC, or getting a good matchmaking group together for MCC, as well as possibly some Reach customs (possibly) or maybe even Halo 5 with Classic/Evolved settings, MasterCh1ef87 created a club for you called “Classic Halo”
