PHASMOPHOBIA is a massively multi-player game of horror in that you act as an investigator of paranormal phenomena. You have to go to various locations, such as houses, schools and hospitals, and look for signs of the presence of spirits and other supernatural entities. Players must use their tools, including thermometers and electronic sensors, to collect proof and then determine what type of spirit they have encountered. Caution is necessary, however, as spirits can attack and even kill players.
