Fatal Frame: Mask of the Lunar Eclipse is a survival horror video game developed by Tecmo, Nintendo SPD and Grasshopper Manufacture. The fourth installment in the Fatal Frame series and the first on a Nintendo console, it was released in 2008 by Nintendo for the Wii in Japan. A remaster for eighth and ninth generation consoles and Windows published by Koei Tecmo will be released worldwide in 2023. The story, set on the fictional Rougetsu Island, focuses on Ruka Minazuki, one of a group of girls who was held captive on the island for unknown reasons. Years after their rescue, still suffering from amnesia, Ruka and the two surviving girls return to the island to seek out the truth. The game's title stems from a ritual mask key to the story. The gameplay, as with previous entries in the series, revolves around the main character exploring environments and tackling hostile ghosts using the Camera Obscura. The idea for Mask of the Lunar Eclipse came to series co-creator Keisuke Kikuchi when he first saw the Wii hardware. Kikuchi and series co-creator Makoto Shibata returned as respective producer and director, while Grasshopper Manufacture's Goichi Suda acted as co-director, co-writer and designer. The gameplay concept was making the player literally feel the fear evoked in the game. The addition of further developers to the project enabled the team to reconsider the standard formula, although it proved to be a chaotic experience. As with previous games, the theme songs were sung by Tsuki Amano. When released, the Wii original became the best-selling entry in the series to that date, and received generally positive reviews from critics.
