Greyhill Incident is a survival horror game that takes you into a world invaded by aliens. You have to play as Ryan Biker, a simple guy with a baseball bat and a revolver with several bullets. Pass through the Greyhill area captured by gray aliens and try to survive. The game takes place back in 1992 in a small remote village. Local residents are concerned about the increasing paranormal phenomena, but no one is in a hurry to call the police for fear of being in a mental hospital. So, the council decided on self-defense.
