As you stay in the dark or witness paranormal events, your sanity drops. Lower sanity increases the chance of the ghost entering a "Hunt," where it attempts to kill players.
The game uses a voice recognition system that allows ghosts to "hear" you. You can use tools like the Spirit Box to ask questions or interact with Cursed Possessions like the Ouija Board.
Improvements were made to the ghost's walkable areas, ensuring entities could no longer walk through sinks or freezers in kitchen areas.
