  • 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?

This game is nothing but a scam. I remember the first trailer and screenshots for the game showing a very different style choice to what we have now. It has been over a year now since the last steam news update. Please save your money and look for something else instead.
