Environmental Sound (Silence 1)

Environment Sound (Silence 1) is a deep, ambient theme in Metroid Fusion. It is heard during the first briefing Adam gives Samus, when they land aboard the BSL. Ingame, it is accompanied by a perpetual alarm sound during that cutscene. It is later heard again when Samus arrives in Sector 4 and Adam briefs her on the Serris creature; this time without the alarm. It is next heard when Samus returns to her Gunship during a power outage and speaks to Adam. In addition to the alarm mentioned before, it is accompanied this time by the sounds of the Dachoras and Etecoons in the background, which Adam had allowed onboard.

The theme can be heard here.
