I must admit I like the look of The Culling! While I like the idea of survival games, they often don't click for me, but a battle royale game I could definitely get into.
Duskers is the rather unique strategy and survival game in procedurally generated worlds. You pilot drones into spaceships and figure out what's going on.
I really liked Retro-Pixel Castles when I played it initially last year, and after trying it again now it has had some major updates I have some more thoughts on it.

7 Days to Die recently released Alpha 14, and with it came broken graphics for Linux gamers. The developers are asking for logs to help them narrow down what's causing it. It sounds very familiar to me.
I am really excited to give Starbound some proper playtime when it leaves Early Access. It's already fun, but I didn't want to have characters or worlds wiped during Early Access. They have put up what to expect in Starbound 1.0.

Fear not ARK lovers, as ARK: Survival Of The Fittest is confirmed to be coming to Linux. We don't know when exactly, but it's at least in their plans for release.
Project Zomboid is easily one of my favourite indie games to keep an eye on. Not just because I love Zombies, but the effort these guys put into the game is amazing.
