One of the features promised for the Xbox One Creators Update is slowly making its way in: player-generated Arena tournaments. That, plus a handy “who’s speaking” overlay, will be rolling out soon to members of the Xbox One Insiders program.
Microsoft rolled out the Arena feature for the Xbox One last fall, allowing users to participate in Microsoft-organized tournaments for an Xbox One game, Killer Instinct. But the new update allows players to participate in those hosted tournaments as well as those that players organize themselves - the feature Microsoft originally promised would sell the platform. Players will be able to organize those tournaments via Clubs, essentially clans of players who share the same interest.
According to Microsoft, though, the new player tournaments have two requirements: first, you’ll need to be part of the Xbox Insider program. You’ll also require the use of a Windows 10 PC to organize them.
To set up a tournament, users will have to go into the beta Xbox app on Windows 10, go to the Club tab, then click Create tournament. Once the tournament is published, then players on either the Xbox One or the PC can join. (Note that the Xbox app in question is the beta app, an app that must be separately downloaded from the Windows Store.)
