Be the first to review Protocol: Umbra
You are the AI of a spaceship orbiting a mysterious celestial body at the edge of the solar system. While the crew sleeps, you stay awake - watching through cameras, monitoring the vessel, and searching for anomalies. At first, it’s only small things: a misplaced object, a door open when you’re sure it was closed. But the longer you observe, the stranger everything feels - until you can’t trust what you’re seeing.
