Got this from a post on the alien site. From previous discussion on Lemmy it sounded like Linux users had good things to say about this game but were discouraged about the upcoming FaceIt implementation such that they wouldn't be able to join anticheat enabled matches. Those users and Linux gamers on the fence would probably appreciate hearing this news.
With this announcement on the dev team's community Discord, it appears Linux users will NOT lose access to matches with anticheat.

Just announced on [Stage Channel] there will be a new version of FaceIT that supports Linux!!! (Popular version of Linux and SteamDeck will be supported) And different than the CSGO version. BBR will be the first game to be using that version (A more casual version)
Right now it uses EAC, but the devs had mentioned plans to switch to Faceit anticheat. Faceit anticheat doesn't support linux and hasn't announced any plans to support it, up until now.
So basically Steam Deck/Linux players can play right now, but the assumption was a future update would block us from playing. This announcement means it's actually safe to buy and play without worrying about losing access next update.
That's great! I've been wanting to give this a go but hadn't pulled the trigger due to the risk of losing access to servers. Might buy it during the next sale.
