Demonsomnia

Demonsomnia is a CO-OP multiplayer bodycam horror game focused on the impact of nuclear reactions. Your goal is to activate the nuclear reactor device and escape without getting caught by mutants.

Demonsomnia offers 3 different game modes.


This mode is weapon-free and filled with intense suspense. Collect the necessary items inside the building without making any noise, and find a way to escape. The executioner inside can hear both in-game sounds and your real-life microphone sounds.


Grab a weapon, head to the forest, and collect the items needed to hunt the demon from the misty woods. The forest is filled with villagers and strange mutated creatures. Once you’ve hunted the demon, inject its fluid and add it to the nuclear device.


Your goal is to hunt the demon in the mansion at the center of this dark village. However, you have a problem: you have no weapons.

This CO-OP game, developed with Unreal Engine 5, offers the highest performance and graphics quality for multiplayer games!

• Body Camera: You have a body camera. Use the radio to report to your friends when you encounter various entities—assuming they’re still alive.

  Equipment: Locate areas with high radiation; these areas contain useful items like radiation salt. You’ll use these items to hunt the demon. Many tools and devices are also available for your mission.

  Buy guns: Weapons such as pistols and machine guns will help you feel safe when you’re alone. Remember, sometimes they’re your only friends...

• CO-OP: Play whenever you want with friends or other players.

  Teamwork: Work in harmony with your friends, cooperate with your team, and maybe even guide them. Everyone needs a leader from time to time; maybe you’re the leader they need.

The government has assigned 4 brave individuals to investigate the effects of nuclear reactions; you are one of those 4. Were these various entities created by radiation, mutated species, hallucinations, or unknown beings?
