Metroid Prime Credits primarily consists of a melancholic melody performed on a flute-like synth, accompanied by a low male choir harmony. The theme also includes a repeating Terminator-esque percussion rhythm, as well as a distorted static-like sound heard in other songs from the Metroid Prime soundtrack. About halfway through the song, gentle piano notes join the harmony.
An abridged version of Metroid Prime Credits, titled Menu Select (メニューセレクト), plays on the Samus Data Screen. The full version, also known as Ending Staff Roll (エンディングスタッフロール), plays during the game's staff credits. In New Play Control! Metroid Prime and Metroid Prime Trilogy, the full theme is automatically unlocked in the Soundtrack Gallery upon beating the game.
The credits theme, titled Metroid Prime - End Credits, appears as the penultimate track in GameSoundTracks: Original Videogames Music Tracks #1, a 2003 soundtrack offered by German gaming magazine Man!ac. Metroid Prime Credits is also included as a track on the Samus Archives Sound Selection CD, where it is simply titled Metroid Prime.
Like many songs from the Metroid Prime soundtrack, Metroid Prime Credits received a remix in Metroid Prime Pinball, playing once again during the staff credits. This version is slightly abridged and features lower quality instrument samples due to the comparatively limited Nintendo DS hardware.
