Metroid Prime 3: Corruption is a first-person action-adventure video game developed by Retro Studios and published by Nintendo for the Wii video game console. It is the 9th game in the Metroid series, and the final entry in the Metroid Prime trilogy—excluding two spin-off titles. It was released in North America and Europe in 2007, and in Japan the following year. The Wii Remote and Nunchuk devices are featured in a new control scheme that took a year to develop and caused the game's release to be delayed several times.
