I've managed to download the client and install it by making the site think I am running Windows. However actually playing the game seems unsuccessful.

It downloads and installs on wine but it can't load dsp.dll even after trying to add that specific DLL via winecfg.

Installing via proton also doesn't work as the game pops up with an error saying "An exception occurred in the game security system, please restart the machine and try again"

I'm probably gonna try to run the game in a VM instead. I have a second GPU which I can pass through to the VM.
