Aurora Unit 313 (theme)

This article is written from the Real Life point of view

Aurora Unit 313 is the theme that plays during the final battle with the boss of the same name in Metroid Prime 3: Corruption. It is a remix of Darkness, Dark Samus's theme from Metroid Prime 2: Echoes, but is arranged to resemble the Zebetite theme from Metroid and Metroid: Zero Mission, owing to the Aurora Unit's resemblance to Mother Brain.

The theme is slow and ominous during the initial phase of the battle, but becomes faster and gains an alien-sounding melody when 313 becomes airborne.

In Metroid Prime Trilogy, the theme has been added to the Soundtrack Gallery along with the Berserker Lord theme in place of the Bryyo Thorn Jungle and Metroid Battle Themes.

The theme can be heard here.
