About 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 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.

Such an interestic concept for a game. Good sound design and atmosphere, it really sucked me in. I was locked in got a bit spooked on a certain event, really caught me off guard. I like the logs and gives a bit more depth. It's a bit short but I did enjoy it, kinda want more of it.4 found this helpful
This is something that you can sit back and enjoy. You kind of have to have a keen eye to see some of the anomalies but you can get away with guessing the right anomaly lol. This was really fun and I like that after each round whether you beat the round or lose, you get more lore with the logs and learn what's going on and who we're protecting. I definitely recommend people to try this and I hope there are more levels in there future. Here's a link to the video I made playing this: https://youtu.be/tsPx_sU3Rsw?si=Oe5K4eGcs93aghsh1 found this helpful
