Do you think Linux doesn't have enough fighting games? Way of the Passive Fist [Steam, Humble Store, Official Site] should hopefully tick a box for you then.

About the game:

A mysterious figure known only as the Wanderer travels across the distant planet of Zircon V, a once prosperous mining colony that is now on the brink of destruction in the face of its dying star. By using the Passive Fist technique, the Wanderer can outlast any foe by deflecting their attacks and draining their stamina. With colonists disappearing and maniacs running wild, the Wanderer must stand firm, stay calm and fight for answers in this unique modern brawler!

The combat system is what makes it sound really great, with you draining the enemy's stamina by blocking, dodging and parries so the enemy will end up defeating themselves as you drain them. As you do this, your "super meter" will fill up for you to unleash your killer move too.

For those who find the usual controls a nuisance, they say that the control system is fully customizable, true freedom to play it your way—nice!

You can pre-order on Humble Store right now, which also shows a Linux "tux" icon. Not that I suggest pre-orders, because they're almost always a bad idea. It's due for release sometime in "Early 2018", with no firmer date yet being given. Anyone else think this looks and sounds like it could be amazing?

Update: If there was any doubt, I tweeted to the developer and they seem very positive about Linux support.
