Confirmed by others as well, the latest Ballistic Overkill that adds in Vulkan and many other things, has completely broken the Linux version. UPDATED with a temp fix.
I recently wrote about how the Linux version of Xenonauts is no longer supported with the developer now saying it's only for 'legacy customers', I reached out to the developer for some answers and here's what they told me.
The developer of NEXT JUMP: Shmup Tactics sent in a key for us to take a look, so look I did. It's interesting, as it's a mix of a shoot 'em up with turn-based tactical battles.
Take this with a pinch of salt, as the Feral incoming port radar seems to be acting up, but it's possible Rome: Total War might be another future port from Feral Interactive.
I'm pretty darn fond of Zombie Night Terror as it brings Zombies into a Lemmings-style game with some comedy sprinkled in and it just got a big free update.
Quite often I visit random games I like the look on Steam and dive into the community looking for posts mentioning Linux. It turns out that Stardrift Nomads, a really good looking dual-stick shooter should be coming to Linux.
Earthlock: Festival of Magic gained a Linux Alpha version last year, but they went pretty quiet about it for a while. They have now confirmed they will continue the Linux version once the WiiU version is finished.
There's some activity on the Mesa-dev mailing list with patches that will enable both Dying Light & Dead Island Definitive Edition (and it seems Dead Island Riptide Definite Edition too) to work on Mesa.
Mesa 17.0.6 is the latest bug-fix release for the 17.0 series, but it also comes with AMD Polaris 12 support for the 'radv' Vulkan driver that has been back-ported.
Another time to show support for a game to come to Linux, if you would buy it that is. The developer of Inner Voices has stated with enough support they will bring it to Linux.
