Energy Zone is the background music for the Energy Zone sections of the game Contra. The song was composed by Kazuki Muraoka. The title is unofficial.
In the arcade game, the Energy Zone is the second section of the final stage with all the torching flames. The song continues to be played through the Hangar section with mine cars and machinery.
In the NES port, Energy Zone is played in stage 6, but not the Hangar stage like in the arcade game. The song remains the same throughout every region and the PlayChoice-10 release.
