Fatal Frame is probably the first Camera Obscura games developed. Known as Project Zero in Europe, Fatal Frame has been one of the most well-received horror games to date. Obviously, given age, the graphics will vary from title to title, but Fatal Frame 4 was the best selling of the series in Japan.
Fatal Frame follows a young girl as she searches for her brother in a mansion--upon discovering that she's locked inside, she must use an old antique camera to escape.
Fatal Frame II: Crimson Butterfly focuses on twin sisters as they happen across an old village and an ancient ritual that damns one sister.
Fatal Frame III: The Tormented shows a young photographer who ends up taking a picture of her dead fiance in a mansion; she then has recurring dreams that turn into nightmares. This installment touches on previous characters and events in the first two games.
Fatal Frame IV: Mask of the Lunar Eclipse was developed for Wii in 2008. Three kidnapping survivors return to the location of their kidnaps to remember what happened.
