Tempest Rising is an upcoming base-building RTS from Slipgate Ironworks and 2B Games with publishing via THQ Nordic and 3D Realms and a first playable preview is out with the first GDF mission.
Playable on desktop Linux with Proton Experimental, the experience was close to flawless. Which is massively exciting to me after growing up playing Dune 2, Command & Conquer, Red Alert and the later games. Tempest Rising is unabashedly taking a ton of inspiration from Command & Conquer but it's all a bit more modern looking and feeling.
On my desktop with Kubuntu, Ryzen 5800x and Radeon RX 6800 XT it worked great. Well above 60FPS at 2560x1440 resolution on the highest settings. The only slight issue I saw was the commander in the mission intro video lip syncing being clearly off with the speech, which is not clear if it's a game issue or a Proton issue.
If you're like me and love your RTS games though, it seems like this is one to keep a close eye on and you can try the initial mission preview until August 28th.
Screenshots below of it on desktop on Epic settings:
Also playable on Steam Deck, although their advertised "Full controller support" doesn't yet seem to be enabled, so setting it to keyboard and mouse in Steam Input worked. You'll also want it on Low details, as on Medium there's a fair amount of drops.

They have a lot to live up to with this game with the absolutely clear C&C inspiration. There's not a whole lot to go on from one mission but it's certainly tickled my fancy here. Lots of fun details in the environments, and the mixture of abilities your units have should be fun in the expanded game.
