Just an update incase someone doesnt know. In order to install the new sounds, you need to first copy the entire contents of your media folder located in the Campaign 1776 folder. The Default location for this would be
C:\Program Files\ HPS Simulations\ Campaign 1776\ Media
You can just copy the whole folder and before you paste it, rename your media folder to backupmedia or something. Then when you paste it it won't overwrite anything.
Take the contents of the Alternate Sounds file and paste them into your media folder.
Pretty simple stuff but I just wanted to make sure no one had any problems with it.
If you all like these sounds, I am sure I can come up with some more for this and other HPS games.
Disclaimer: I take no credit whatsoever for the sounds that are in this download. They were taken from various retail games and online resources. I tweaked them a bit shortening some and lengthening others but I didn't make any of them.
