Can anyone help me find the complete soundtrack to the PC Game "Trespasser" composed by Hulk 2 and NY CSI composer "Bill Brown" Its incredible soundtrack to have. I saw there was one to download two year ago.

You can actually download a good amount of tracks right from the composer's portfolio:

I'm not sure if this is the full soundtrack though, but it's certainly worth it. :)
