In my search for scream samples with a compatible license, I didn't have much luck so far, but I did come across some other VST instruments for making some soundtracks that I think sound nice. I threw together a track and have it posted on my own website under "downloads" listed as "Track 4."
www.destructavator.com is the main URL, from there click the button next to "Downloads" and it can be found under "MP3 files only," track #4.
Does this sound original and like something that could be used for the game?
