Kosmosis - about the game

Two xenobiologists find themselves stranded on a mysterious planet that appears intent on their anihilation.

Explore the eerie landscapes shrouded in darkness, solve intricate challenges, and battle against the relentless forces of this hostile world.

Each decision you make could mean the difference between survival and becoming a victim of the planet’s deadly secrets.

Will you uncover the truth behind Simon's disappearance and escape the clutches of this hostile environment, or will you succumb to the horrors of Kosmosis? Your fate lies in your hands.
