Phendrana Drifts is the main theme of the area of the same name in Metroid Prime. It was also re-arranged for the pinball table based on the Phendrana Drifts in Metroid Prime Pinball. It begins playing ingame when Samus enters the Phendrana Shorelines; in the rooms before, "Ice Connect" is heard instead as a lead-in. This theme is meant to build-up to its faster-paced remix, Phendrana Battle, featured in the back half of Phendrana where Samus obtains the Gravity Suit. In the Metroid Prime & Fusion Original Soundtracks, this theme is titled Ice Valley (アイスバレイ), as the area is in the Japanese version of the game. It is one of several themes that can be purchased from the Soundtrack Gallery in New Play Control! Metroid Prime and Metroid Prime Trilogy.
The Hunters theme, Arcterra (an unused name in the internal BGMSELECTLIST.DAT file), begins playing when Samus enters the Ice Hive, and can also be listened to in the Music Test after Gorea's second form is defeated. A portion of this theme is included in the Hunters theme. It was arranged by Lawrence Schwedler and James Phillipsen. This version makes changes to the melody, and plays the Phendrana theme in the parallel minor key of its original major key. In addition, it incorporates some notes of Noxus' theme. Arcterra has a more subdued and ominous tone than the original theme, but still becomes energetic and hopeful-sounding with added instruments after the first minute.
