The developers of Helium Rain sent word that their realistic space simulation game will fully support Linux at launch. The main developer is also using Linux to make the game.
You may not remember Astroneer, as I covered it late last year as a possible game coming to Linux. The developers have since been back in contact with me to confirm a Linux version is coming.
Best Buds vs Bad Guys is another game that has sadly seen a delay of the Linux version. I'm a little sour here since I funded it on Kickstarter (broke my own rule there!).
Ethan Lee sent out a teaser tweet earlier about Owlboy, as it seems he is porting it and wanted to get in first before it ends up popping up on SteamDB.
Sometimes I get sent really interesting things to cover and sometimes I get sent some really basic, terrible stuff. Porradaria Upgrade & Porradaria 2: Pagode of the Night are two that firmly sit in the terrible pile.
Defender's Quest: Valley of the Forgotten (DX edition), the rather excellent Tower Defence and RPG hybrid has been updated to get gamepad and Steam Controller support.
Everybody’s favorite rocket-powered-cars-hitting-oversized-balls-competitively game has gotten another one of its hefty updates. There’s a new space-themed arena, car and a series of new drops and features for players to enjoy.
This is one that’s heavy on the action and explosions. With over-the-top weapons and fast gameplay, 4Team is about seeing who the last man standing will be.
It seems GSC Game World have run into a few technical issues with their new DLC for Cossacks 3, so they have pushed back the DLC release date which has also delayed the Linux version.
Shadow Tactics: Blades of the Shogun is the rather good top-down stealth game from Mimimi Productions. It's now out way a day-1 Linux release and it has a demo.
