For all of you who bothered to read this, here's the low down:
This sound file is chocked full of loud, hard-core, in-your-face, and just plain mean sounding clips I assembled together to further amplify the already intense Marathon experience. By all means hook your computer up to your stereo and recklessly crank the volume to a level that'll get the cops knocking with their guns drawn. (Everything sounds like it hurts a lot more now.)
To get this sucker to work, change your original sound file's name to something like Sounds.Orig or whatever. Then change my sound file's name to Sounds. It's just that easy. No gluing or tools required.
These sounds work fine with the Beta and the Demo. (I had problems with the Beta before, but everything seems to have ironed itself out. Still, use caution.)
Be sure to look for a fuller version when the release is out.
