Interstellar Marines was one of the most promising FPS games in a long time, until they basically ran out of money. They're still going and this latest updated fixes a long-standing Linux issue. I also really missed playing this game!
Voxel Turf is a very sweet mix of city-building and first-person action built by one developer on Linux. Recent updates have been pretty sweet too.
I recently wrote about Super Cane Magic ZERO getting a huge update and how the Linux version was broken, they've now acted on my feedback and it's fixed.
Balloonatics certainly gets some bonus points for being unique. A vehicle-based action-packed shooter where you pilot a floating basket will release for Linux next month.
Geneshift, the pretty good top-down shooter that has some fun vehicle action was just recently updated with a major rework of the progression system.
Super Cane Magic ZERO is a game I showed off a little way back in April of 2016, since then it's had tons of updates and recently a big story expansion.
Long overdue, but the developers of RUINER have actually confirmed now that the Linux version is in progress.
A rather interesting looking fast-paced FPS released with Linux support recently called Cold Space, I took a look to see if it's any good.
Having already gone to the trouble of getting the original Doom 3 binary working on my modern Arch Linux system a few months back, it made me wonder just how much effort it would take to get the closed source Quake 4 port up and running again as well.
Cendric is an interesting discovery, a game this mixes platformer gameplay with an RPG and it will launch with Linux support in March.
For those excited by Next Up Hero, the new 2D action game from Digital Continue & Aspyr Media we have somewhat bad news, as there's no Linux support during Early Access.
Spartan Fist, a first-person puncher roguelike from Glass Bottom Games looks fantastic and the good news is that it's heading to Linux.
Can't get enough hardcore platforming? Good news for you, as the colourful and musical ERSATZ now supports Linux.
If you play only one twin-stick shooter this month, make it 'JASEM: Just Another Shooter with Electronic Music' as it's properly good.
AT SUNDOWN looks like a pretty fun shooter, one where the map is covered in darkness and light is your enemy.
