Our take on Project Unknown

Rather than treating ghosts as straightforward combat targets, the game makes observation part of exorcism. Players record behavior, identify cursed belongings, and manage darkness and miasma while working through client requests in co-op.

What is Project Unknown?

Project Unknown is an online co-op horror game in which members of Paranormal Property Solutions respond to clients with haunted properties.

Players investigate supernatural activity, record ghost behaviors in a journal, locate belongings connected to curses, and attempt exorcisms while staying alive. Each playable character has distinct traits and a special ability, including tarot cards that link two players' fates. Missions take place in haunted houses and other supernatural locations affected by darkness and miasma. Lighting is limited because too many open lights can trip the breaker, while unchecked miasma can make a request impossible to complete. Players can purchase and use equipment such as a Ghost Magnifier, Ritual Bell, Curse Sensor, and Flashlight Unit.
