As a gifted member of Paranormal Property Solutions (P.P.S.), you will tackle requests from troubled clients and exorcise the evil spirits haunting their discounted property. Exercise caution as you help clients sell their house ghost-free and secure your well-earned share!
Navigate through the diverse range of supernatural phenomena that’s plummeting the price of the property while staying alive!
Brace yourself for chilling encounters with many ghosts, each possessing a uniquely horrifying visual appearance. Learn more about their patterns and write down their behaviors in your trusty journal to learn how to survive. Finding the belongings where they store their curses is key to the exorcism, but so is making it out alive!
Darkness
Apparitions do not like the light, so you can only have limited amount of lights open at any given time or else risk tripping the breaker. However, darkness in these haunted homes is not the same darkness you’re used to. Avoid it at all costs!
Miasma
Fight back against an encroaching phenomena spreading in each client’s house and cleanse it. Let it get too out of hand, and fulfilling the request might be a lost cause!
Meet a diverse cast of characters with distinct traits, personalities, and abilities. Led by bravery, curiosity, and a relentless pursuit of truth, each member has their own unique ability to help them overcome the challenges that lay ahead!
Eirene is a high roller tarotist that uses her cards to impose a shared fate between her and her teammate
Zay is a quirky school teenager that regrets joining the team but his dog sure doesn’t

From ancient relics steeped in mystery to state-of-the-art ghost detection devices, equip yourself with these visually captivating tools that seamlessly blend functionality with aesthetic appeal.
Gain access to a range of specialized tools to aid you in fulfilling your client requests, such as the Ghost Magnifier, Ritual Bell, Curse Sensor and Flashlight Unit. Use all of them wisely to navigate through the threats and complete the exorcism.
