Environmental Sound (Tension)

Metroid Prime & Fusion Original Soundtracks is a tense, atmospheric theme in Metroid Fusion. It is first heard when Samus enters a dimly lit shaft on the Main Deck for the first time and continues as she goes to the Quarantine Bay. It stops once she uplinks with Adam after returning from the Bay. The track's purpose is to build suspense leading up to the Quarantine Bay, where an explosion was reported.
It is later heard when Samus uplinks with Adam after defeating Yakuza and restoring auxiliary power to the BSL station, and the computer directs her to locate the source of the vegetation choking the Reactor Silo. The theme continues until Samus encounters the SA-X. It is heard again a final time when Samus enters Sector 6 (NOC) to defeat the Security Robot B.O.X., and is warned by Adam that the SA-X is tracking her.
This theme somewhat resembles that of the Wrecked Ship in Super Metroid.
