Game dev specifically notes that linux will not supported. If you play on linux, once this releases you will only be able to join lobbies with the very few other linux players currently playing. You will not be able to cross play with your friends.

When booting you are met with " Failed to setup. Youc can continue without the Anti Cheat, however you will only be able to create and join unsecure matches."

Welp, time to leave this one.
