Dead Maze is a colourful and quite interesting free MMO that has Linux support. It's currently in a closed beta, but they've now announced the release date for everyone.
I do love Dota 2, in fact I was completely addicted to it some time ago clocking hundreds of hours into it. This update might pull me back in, as I like the sound of what they're doing to improve the experience.
Slime-san is a very impressive platformer, it's challenging and the controls are super tight. It's about to get another expansion, which will be free for existing owners.
Tangledeep is now ready for the masses, as it's officially left Early Access. This roguelike is not just pretty, it's also very welcoming to new players.
Delver is a positively rated single-player first-person dungeon crawler, which has just today left Early Access. It has also seen the return of the SteamOS icon for it.
A little late, but better late than never. Feral Interactive have pushed out an updated build of XCOM 2 for Linux. There's also now the XCOM 2 Collection you can buy.
Thanks to Steam's new curator system, we get sent keys to various games where developers want us to review it. I took a look at Powerless and I was not impressed.
There's always going to be problems when developers are able to set anything they like on Steam with no proper checks from Valve. Despite listing SteamOS/Linux system requirements and showing a SteamOS icon, BATTALION 1944 is not coming to Linux.
The developers of Ballistic Overkill have pushed out a new update which features a major change to the way Team Deamthmatch works, they also added in Steam Workshop support.
I've been mighty impressed by Hollow Knight, not just because the game is beautiful, but their support in the form of free content updates is awesome. Hollow Knight: Gods & Glory has now been announced.
Is there anything more amazing than a developer going through all their games to add Linux support? Jackbox Games, Inc. are continuing their effort with Quiplash & Fibbage XL now in beta for Linux.
Overload is a really quite fantastic six-degree-of-freedom shooter and they've said for a while they will add in multiplayer, turns out it's not that far off now.
I wrote about the cute looking MMO 'Tale of Toast' quite recently, although they didn't have an actual date set for their Early Access launch. They've now put up a date and Linux support will be same-day!
