Game did not run without tinkering. Initially I could not get the game to load, it would just be a black screen, spin one CPU core at 100% and never load. Then I installed Lutris, switched Steam to use Proton Experimental and adjusted my launch options. Then the game ran beautifully on max graphics settings. I've made it to level 8 with no bugs or glitches. I read others posting that team play performance was not good but I have only played solo.

I really like this game and I'm glad with minor effort I got it running on Linux.
