if you synch 'Cockroach Attack' from the soundtrack to Damnation Alley by Jerry Goldsmith to the CGI Fifield attack it works pretty well and has that weird discordant ALIEN soundtrack feel. I mean it's only proper to pinch an earlier Goldsmith track, it's tradition.
Just an observation. You can probably get the soundtrack from Itunes or MP3Panda if you're interested in trying it.
