I love pretty much everything Klei Entertainment make and Dread Pilots looks great, a space survival game where you're exploring a mysterious and hostile pocket universe called the Dread. From the creators of Don't Starve, Griftlands and Oxygen Not Included - you know it's likely to be good.
"The Dread is a pocket dimension somewhere between deep space and a nightmare. You face mutated, carnivorous plant life, mind-bending anomalies, living computers, fanatical cults, space vampires and more as you traverse its many regions in a desperate search for resources and allies. Explore dark infected caverns, soar past glistening technological landscapes, and navigate chaotic mineral fields, all animated in Klei Entertainment's signature hand-drawn 2D style."
Definitely feeling a fair bit of Sunless Seas / Sunless Skies in the gameplay here, check it out:
When it comes to Native Linux support, in a reply on Twitter they mentioned:
Like our other titles we'll explore that once we've got a bit farther on PC development to focus our development team, but exploring that is on our radar especially with growth of Steam Deck popularity. Too early to fully test and commit at the moment, but it will be explored!
I'll be following this along with great interest, hopefully either way it will work on Linux (and Steam Deck) at least with Proton there's a good chance regardless.
You can follow it on Steam.
