Now this looks exciting. Taking inspiration from the likes of Deus Ex, the old-school atmospheric immersive sim Core Decay had a new trailer during Realms Deep 2023. Coming from Ivar Hill, Slipgate Ironworks and 3D Realms, last I heard it will have Native Linux support too.
More about it: "The year is 2089. For decades past, the availability of natural resources and livable conditions has declined to the point of societal collapse. Nations have made room for city-states and corporations, and the planet is on the brink of an ecological collapse that will leave nothing left alive.
During mankind’s last breath arises a shadowy network of conspirators, bent on saving the human species using any means necessary – even if it means sacrificing all it means to be alive.
Follow the trails of a mysterious organization across a dying Earth, in an atmospheric singleplayer adventure spanning seven locations across six continents."
