Music from Metroid: Other M. This tender piano composition opens up Nintendo's teaser site for the upcoming Metroid game, accompanied by a rare Samus Aran audio clip (in Japanese): "A dream. It's as if I was watching a playback of a tragedy that really happened."
Metroid: Other M is slated to release in Japan this summer. Nintendo also revealed teaser sites with similarly sentimental music for two other Wii games: The Last Story from Archaic Sealed Heat developer Mistwalker; and Xenoblade (formerly Monado) from Xenosaga/Baten Kaitos studio Monolith Soft.
