Aliens Vs Predator 2 - Way To Extract Sounds?

Here's what I'm attempting to do:
I'm making a movie for my media tech class that is a knockoff of the movie Predator. I would like to add some predator sound effects, but I'm having some trouble getting them. I thought about getting some of the sounds from the DVD movie, but often, the sound effects would have a music track behind them. So basically, I need a way to get the predator sound effects from the PC version of Aliens Vs Predator 2. People make sound mods for the game, so there's gotta be a way to get the sounds from the gamefiles.

Thanks for any info!

You should do a google search for aliens vs predator 2 sound clips, or look around a site such as http://www.wavcentral.com/ Wav download websites will usually have popular clips from movies if you need em'.

Yeah, I've been to wavcentral. Great place, but some of the sound effects for this movie are too short, or have a bad sound quality. I've tried AvP 2 sound clips in google, but I keep finding tons of info on the game, reviews, and downloading different sound mods for the game. Unfortunately, those mods are in a stange file format, and I have no idea how to extact the actual audio from those sound files.

Thanks for taking a look!
