Overview

About this game

You are the AI of a spaceship orbiting a mysterious celestial body at the edge of the solar system. While the crew sleeps, you remain awake, observing, protecting, and monitoring every step of this mission. However, it seems the ship and its crew are not the only ones circling this object.

Even after the mission ends, something doesn’t stay behind.

Using security cameras, your function is simple: protect, guard, and monitor every corner of the environments under your watch. Nothing can go unnoticed. You are alone on this mission, relying only on your memory and circuits to guide you.

Key Features:

  • 11 detailed rooms across 2 maps: Monitor several distinct areas, from the orbital ship to a facility back on Earth, each with its own feel and layout.

  • 3 progressively harder difficulties: Test you awareness and memory against increasing difficulty levels.

  • 80+ unique anomalies: From things you might miss... to things you can't.

Protocol: Umbra is an observation and memory game in which the player must identify anomalies and unnatural alterations occurring within monitored environments, report them, and neutralize them while trying to survive through multiple nights that grow increasingly complex the longer the situation unfolds.
