This guide will allow you to return the multiplayer to XCOM 2 WotC and play it with friends, as well as participate in tournaments.
How to Restore
To re-enable multiplayer you need to visit the game’s properties in your Steam library.
Here we open the Betas section and select the only available branch.

Closing thoughts
As far as I understand, this beta is for a version before the “multiplayer servers” were disabled for XCOM 2 multiplayer. However, the matches use Peer-to-peer connection, which means there is no middleman needed for the players to connect. Therefore you can play again with little issue.
We are regularly playing multiplayer on our Discord server. If you want to find an opponent – swing by, we have over 100 enjoyers of the game there already. We have also developed our own multiplayer mod that adjusts balance, adds more units to PvP (including the Chosen) and fixes most of the bugs present in the vanilla online matches.
