Barotrauma is another chance to head out to sea for free, as this Windows, macOS, and Linux submarine simulation is also conducting a free weekend on Steam. This will give players a few days to experience its claustrophobic survival/horror gameplay and pick it up for half-off if they find themselves immersed. The sample includes the new Calm Before the Storm update which adds new features and modules. Here's the pitch on the game:

Barotrauma is a 2D co-op survival horror submarine simulator, inspired by games like FTL: Faster Than Light, Rimworld, Dwarf Fortress and Space Station 13. It’s a Sci-Fi game that combines ragdoll physics and alien sea monsters with teamwork and existential fear.

In the not too distant future, humanity has fled to Jupiter’s moon. With its irradiated icy surface, life can only be found in the ocean below. Travel through a punishing underwater environment and make friends or rivals of the four factions of the world. Discover what lies in the depths of Europa.
