Unknown

Unknown follows a girl who has suddenly lost both her parents. A woman claiming to be her father's friend takes her to a strange mansion with no windows. While exploring, the girl overhears the woman talking with an old man; they spot her, go outside to continue their conversation, and a lightning bolt destroys the gate's front post, trapping her inside. She encounters a creature and tries to escape it.

Choices and pursuit

Your behavior affects your affinity with other characters and can change the ending. The Stalker does more than chase you: it also tracks your traces.

Exploring the mansion

You can move between rooms on the same floor without loading. The game uses 3D sound, which changes according to your position and orientation.
