Hey friends,
so, Linux has become a major headache with several SDK updates that turned out to be incompatible. We gave our best, but so far this was not good enough, we could not get it to work properly and hence we will launch without a native Linux version this year. We will revisit the topic sometime after launch, though. I'll let you know when there's an update.
However, in our tests the Windows Steam version worked fine on Linux using Steam's compatibility mode (Proton). So you won't have to worry if you only own a Linux system
Thanks!
Markus
