Phasmophobia is a cooperative horror investigation game played from a first-person perspective, supporting one to four players. Players take on the role of ghost hunters who must identify the type of ghost haunting a designated location by gathering evidence using various paranormal investigation equipment. The game features speech recognition, allowing ghosts and certain equipment to respond to words spoken by players. As investigators spend time at the site, their sanity decreases, eventually triggering hunts during which the ghost actively pursues and can kill players. The game includes multiple location types of varying size, twenty-nine ghost types each with unique behaviors and evidence, and a progression system where players earn money to unlock and upgrade equipment. Virtual reality is optionally supported.
