Some hunters find the gun sounds loud and distracting, this mod replaces the gun sounds with the bow sounds. It only affects how the shooter hears things. There are no lua or XML files, only the audio files (from the original game) which get extracted to different filenames to override the other sounds.
I like the softer bow sounds, but I'm considering making an alternative mod with the gun sounds modified to be much more quiet. If you're interested in this instead, post a comment.
