Infiltration is a song from the Bionic Commando series composed by Harumi Fujita. It was first featured in the original Bionic Commando arcade release and appears in several other releases.
Bionic Commando (ARC)
Infiltration was originally composed by Harumi Fujita for the arcade version and plays in stage 3: Infiltration.
This song was included on the Legend of Game Music: Premium Box album. It's track 52 on disc 3, and it has the title "Big Fortress".
The song plays through a YM2152 sound chip and is song number 0x04 in the game's sound test.
Bionic Commando (AST)
Infiltration plays in stage 3 in Atari ST port, just like the arcade game, but unlike the arcade game, it's also used for the loader music. The song has been given some unique flair by Tim Follin. This song is track 4 in the SNDH file and plays on the YM2149F chip.
Bionic Commando PAL (C64)
Bionic Commando had two different ports for the Commodore 64, one for North American, which did not feature this song, and the PAL version for Europe which did. Like the arcade game, Infiltration is played in the third stage of the game. The song is track 7 in the SID file.
Bionic Commando (ZXS)
Heat Wave plays in the third stage in the ZX Spectrum port. Despite the lower quality of the AY-3-8912 audio chip, Tim Follin made a pretty decent arrangement of the song. The song is track 3 in the AY file.
