Conrad Stevenson's Paranormal P.I. is a first-person single player ghost hunting simulation.
Start a paranormal investigative career from your office in the town of New Eidolon. Initially the locations to investigate are limited, but by becoming more successful as a paranormal investigator you will be invited to new locations.
Each new investigation randomly spawns a different type of ghost, and each ghost has unique behaviors which could vary your approach to investigating.
In general, an investigation will take less than an hour to obtain satisfactory evidence.
