X Invasion Detection (X侵入発覚)[1] is an intense theme that plays in Metroid Fusion shortly after fighting Arachnus. Upon Samus's return to the Navigation Room, Adam will tell her that the X Parasites have invaded Sector 1 (SRX), infecting the atmospheric stabilizers and changing the climate of Sector 1. Until Samus descends to the Main Elevator, this theme will play. It stops when the SA-X makes its first appearance.
The theme can be heard here: [1]
