Original article text below:
Hunt: Showdown, a popular multiplayer game has been broken on Steam Deck / desktop Linux due to Easy Anti-Cheat.
It seems an update released on November 16th just causes players to get kicked from the game. A similar issue to what happened with Apex Legends recently. I've yet to see Crytek comment on this, so I have reached out today see if they're aware and if it will be fixed. The game is currently rated Steam Deck Playable so either they need to fix it, or Valve will need to change the rating over to Unsupported.
Trying it myself today and it's clearly broken (screenshot from Steam Deck):
Hopefully given the popularity of the Steam Deck, and with the new Steam Deck OLED release, more developers will actually test instead of just pushing out updates like this that break it.
