More about Baryum

Baryum is a first-person space sim set in the real solar system at true scale, with every planet where it actually is today. Players begin as a CADET docked at the International Space Station, with a small ship and a flight computer that talks back. The game features eight planets and sixteen moons, real orbital positions, and contracts like planetary surveys, resource runs, and bounty warrants. Players climb officer ranks through Academy exams and engage in ship-to-ship combat against factions. The solar system's scale is maintained with real distances, requiring careful management of fuel, oxygen, and radiation. An anomaly near Neptune drives the story, leading players into the outer solar system where physics behave unpredictably.
