Steam is also holding a free weekend for Stardeus, the Early Access science fiction colony sim for Windows, macOS, and Linux from Kodo Linija and Paradox Arc. Everyone has a few days to experience the full game for free, and it's on sale for half-off if you decide to buy it. Word is this is to celebrate the myriad improvements in the game since its Early Access launch: "Ever since the the [sic] ship combat update, we've pushed over 20+ more updates with fixes, balancing and updates." Here's what this is about:

Inspired by Factorio and Rimworld, Stardeus is a deep colony sim set on a broken starship manned by drones and hibernating human survivors. As the immortal AI you will have your drones repair your starship, save or exploit your human crew and travel the stars in this beautifully complex simulation of a procedurally generated universe.
