About the Game

On Halloween Island, engineers test the innovative way of generating heat. The roots of the power plant reach deep into the earth, all the way to the heart of Hell, where the reactors obtain energy from burning souls.



When an accident happens, the infernal radiation contaminates the earth. Inhabitants living in defiled areas struggle with numerous possessions. An exorcist is needed.



  • Help of the rescued residents.
  • Free exploration of the rich world.
  • The choice of the order of exorcisms.
  • Cooperation on one screen.



  • Very simple gameplay, very difficult opponents.
  • Dynamic clashes.
  • 20 demons with unique abilities and battle patterns.
  • A dark history of the island hidden in the reports of the possessed.
