Like me, if you've been eagerly waiting The Signal From Tölva for Linux, you may be in luck sometime soon as it looks like a Linux version is now in progress.
Griftlands is another game in development from Klei Entertainment! I apparently missed the announcement, but it looks good and I asked Klei about Linux support.
Deep Sky Derelicts has been announced that will be a turn-based strategy and RPG with tactical card combat. It's inspired by the likes of Darkest Dungeon and FTL: Faster Than Light and it certainly looks good.
Planet Nomads is a survival game that, when finished, might seriously be the one for me. It has crafting, vehicles you can build, excellent graphics and this new update seems solid.
spaceBOUND recently released on Steam in Early Access, but it needs a wee bit of work before we can see what we think. Shame, because it sounds like it's quite interesting.
ASTROKILL is a game focused on combat without compromising realism and it looks graphically amazing. If you have a beefy computer, the developer is seeking testers.
I discovered Dead Maze recently and decided to wait to see what the current status of it was, it turns out the developers are planning Linux support of this MMO.
We Happy Few, the game about a drug-fuelled, retro-futuristic city in an alternative 1960s England is to launch in April next year. The Linux version should be on or shortly after too.
