Protocol: Umbra description

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, protecting, and monitoring every step of the mission. Yet the ship isn’t alone: subtle disturbances circle the object, and strange patterns begin to emerge in the hull readings and camera feeds. You patrol the corridors with only your memory and the circuits that bind you to the vessel, ever vigilant as the unknown hums in the background.

Using security cameras as your eyes, your duty is clear: protect the ship, guard every corner, and monitor every system. You are isolated on this mission, guided solely by data and recall, assembling clues from feeds to keep the crew and craft safe as the orbit continues.

Key Features

  • 5 detailed rooms that reveal the ship’s inner life and hidden corners
  • 7 nights that grow progressively more complex as the orbit persists
  • 40+ unique anomalies and alterations to identify and counter

Gameplay Overview

Protocol: Umbra is an observation and memory game. Your task is to watch for anomalies and unnatural alterations unfolding within the vessel, report them through your interface, and neutralize threats while you strive to survive across multiple nights. The longer the ship remains in orbit, the more intricate the evenings become, demanding sharper memory and quicker action. Each night brings new disguises, timing quirks, and evolving patterns that test your ability to connect distant feeds and recall past events.

As the lone guardian, you balance detection with deliberate intervention. Identify subtle irregularities, determine whether they’re harmless decoys or deliberate intrusions, and apply countermeasures to restore stability. The core loop emphasizes careful observation, precise reporting, and timely containment, all within a quiet, high-tension atmosphere of surveillance in deep space.

Experience and Tactics

Expect a focused, cerebral challenge that rewards memory and pattern recognition. The AI’s perspective emphasizes calm analysis over brute force, with strategic decisions shaping the ship’s fate. You will map anomalies, log events, and execute sequences to counteract disturbances—often under pressure as night cycles intensify. The soundtrack and visuals reinforce isolation and meticulous vigilance, inviting careful planning and precise timing as you navigate the ship’s changing silhouettes against the vacuum outside.

In Protocol: Umbra, your perseverance determines the difference between a quiet return to orbit and a mission compromised by the unknown. Stay vigilant, log every anomaly, and act decisively as you guard the corridors, report the data, and keep the ship intact through the growing nights.
