@spoletta Thanks for clearifying. I was on vacation and was glad to read about the extension afterwards.

I've installed it with Lutris on Archlinux and it seems to work. But I cannot participate on the current playtest for some reason, so all I see is the login screen and the message to buy a founder pack.

But native Linux support would be even better I think. When it launches on Steam again, I would expect it to work out-of-the-box with Proton anyway, but that's a guess.

Though the playtest has been extended until tomorrow, I'm not able to play. Wanted to try the game, but when I press login it says that I don't have access to the game, and I have to buy a founder pack.

Just to let you know...
