I crowdfunded Wolcen Lords of Mayhem back when it was on Kickstarter as Umbra. Hoping they would do a Linux port and implement co-op they finally finished it and runs great in Proton. I'm assuming it will probably never get a Linux port, but as long as my investment was well rewarded I'm ok with playing in Proton.

I was able to run Wolcen with all the settings on high and can play offline or online without any serious issues. This game is beautiful! Epic animated backgrounds with waves and soldiers... I'm not regretting my $15 cost years and years ago.
