Guide for Phasmophobia is a 4 player online co-op horror game that allows you and your friends to experience the thrill of the hunt, the fear of the unknown, and the thrill of death.

You will enter haunted locations filled with paranormal activity and you will need to use your ghost hunting equipment to search for and record evidence of whatever ghost is haunting the location. You can choose to support your team by monitoring the location with CCTV cameras and motion sensors from the safety of the truck or you can get your hands dirty with the ghostly activity that will get increasingly hostile as time goes on.

The game is based in the midst of a paranormal crisis that you and your team of paranormal investigators will need to solve. You can choose to play the game with a friend or you can play it alone.
