Metroid Prime 3 has been given its full official title of Metroid Prime 3: Corruption, with its first official screenshot from the E3 floor.
There are also a few new details too. You'll be charged with destroying corrupted Phazon seeds, which involves a considerable amount of space exploration and an eventual showdown with Dark Samus.
Nintendo is also promising a "quantum leap in first-person control". Moving Samus is activated by the Nunchuk controller, while aiming is achieved via the pointer. It's being labelled by the publisher as "the ultimate device for the first-person shooter genre", with the promise of controls outside of the usual genre boundaries.
