As a Linux dev & user, it saddens me to see the Linux version of the game put on the back burner.
I've noticed that Squad has Wine support due to a specific version of EAC. Would the devs consider using that version (might be beta) in order to support the multiplayer-deprived Linux users?
It reduces the testing that needs to be done over a straight Linux port as compatibility issues will be down to the Wine/Proton layer itself. Sandstorm runs pretty alright under Wine emulation.
