Scary Mansion is an adventure horror game with a first-person view and stealth elements. They say there is something terrible about Friday the thirteenth. But not everyone agrees to this. However, just on Friday the thirteenth, postman Freddie Williams arrives at the old mansion with a package that needs to be delivered. The mansion is located on a back street near a dark abandoned mental hospital. Long ago, the mansion's owner, Dr. Jason Crow, was a patient there, although no one has heard from him since. Freddy reaches out to ring the doorbell and then someone or something pulls him inside. He loses consciousness. Waking up, he realizes that he is locked in a den of evil and cannot get out. A bad feeling arises in him.
