Last Epoch is turning out to be an impressive action-RPG with good Linux support, with a developer I've been impressed with and a huge new feature-filled build is out.
Kingdom Rush Origins, the excellent tower defense game from Ironhide Game Studio is seeing some great updates, with another campaign named Forgotten treasures now up.
Estranged: Act II from solo developer Alan Edwardes is pretty impressive and it continues to see improvements during Early Access. Another update is now out!
Easily one of my top 10 favourite Linux games released last year, Dead Cells, is about to get a huge free update. There's also a sweet mini documentary about the developer.
I was very impressed with Rise of Industry last time I took a look at this strategic tycoon game from Dapper Penguin Studios. They have another big update out along with an announcement about leaving Early Access.
Showing some good post-release support, Kite Games and Kalypso Media Digital have pushed out a free content update and a new DLC for the strategy game Sudden Strike 4 today.
Rocket League, the game that sucks away most of my gaming time has a fantastic update now out that allows you to party up with friends across different platforms.
While their newest report is rather late, given that it's for December, the RPCS3 team does once again show some impressive progress for this PlayStation 3 emulator.
