Pirate Yoin



Pirate Yoin (as named internally) is an ambience in Metroid Prime. It plays in areas of significant Space Pirate presence, namely Glacier One and the Phazon Mines, when all Pirates in a room have been killed. The theme is slow and heavily atmospheric, themed around emptiness. It should be noted that "yoin" is a Japanese word that translates to "reverberation", "resonance" or "repercussion", fitting considering how it persists after all Space Pirates have been culled from a room. It was composed by Kenji Yamamoto, and is one of the few themes from Prime that is not included in the Metroid Prime & Fusion Original Soundtracks. The Pirate Fear theme in Metroid Prime 2: Echoes serves a similar purpose.
