Protocol Nightmare
Steam
Protocol Nightmare Is a first-person horror game that combines exploration, survival, upgrades, and intense chases. You will have only three nights to uncover the secrets of the facility — while more than 10 different monsters relentlessly hunt you down.
Trapped in a mysterious location filled with power failures, broken cameras, and creatures that move through the darkness, your only chance is to stay one step ahead of whatever is stalking you.
More than 10 unique monsters Each creature has its own behavior, sounds, and hunting strategies. No night will ever be the same.
Flashlight and task scanner Use your flashlight to illuminate your path and repel certain threats. The scanner helps you find tasks scattered throughout the map — essential to keep systems running and to survive.
Task System There are two types of tasks: • Normal tasks: repair cameras, lights, and essential systems. • Special tasks: unique events that completely change the course of the night.
Secret paths Discover hidden passages that allow you to escape monsters, access exclusive rooms, and reveal pieces of the story.
Player upgrades Improve abilities such as speed, stamina, flashlight duration, scanner accuracy, and other crucial advantages for survival.
Three nights of pure terror and adrenaline Each night increases the intensity, monster aggression, and task complexity. Survive… if you can.
Cinematic atmosphere and heavy tension Dark lighting, unpredictable sounds, jump scares, and random events create an experience where you never feel safe.
If you enjoy psychological horror, intense chases, and oppressive atmosphere, Protocol Nightmare delivers an adventure full of adrenaline, mystery, and pure despair.
