It starts with "Opening/Chase", which sets pulsating synth bass notes
that starts slow and then speed up and settle into a groove against some big
block chords.
"The Probe/Flashback" begins with a blaster beam-like sound and
then goes into a tender and dreamy atmosphere.
This is followed by "Space Armageddon", a short cue of menace
and dread that also has blaster beam-sounding notes in it,
as well as some dense string-like synth writing.
After that is the spare and suspenseful "Stun Gun", perfect
"creeping up on someone" music.
The blaster beam-like thing kicks off another short cue, the
agitated and bleep bloopy "Computer Duel", which combines
some of the approaches used so far with very electronic sounds,
almost like a video game cue.
Then things get rhythmic and more conventionally musical
for "Final Confrontation", which returns to a synth bass line
and chords.
It ends with "End Credits", a heavy piece with lots of
blaster beamish notes and strong chords from the synthesizers,
recalling the feel of some of past cues.
