Ostranauts is a noir spaceship-life simulator set in the NEO Scavenger universe. The earth has suffered a cataclysmic collapse and the rest of the System lives on in a state of capitalistic dystopia. In this world, only the strongest survive, or those with less integrity.

In Ostranauts you create your own captain and build or customize your starting ship from the spoils of your battles. You can build your ship in any shape by using functioning modular parts. The parts have physical properties, interact with each other, and can wear out over time. Manage everything, from work to pay for the fuel in the tanks, to taking care of the physical and emotional needs of your crew and, of course, to make sure the debt collectors that are just waiting for you to file for bankruptcy stay away from you just a little bit longer.
