I edited some of the sound files for HCE.
Changes include slightly lowering the .wav decibals for some of the sounds that could give you a heart attack. Also, some of the sound's tones were lowered a bit for less screaching and more BOOM. The missile explosions now have a very short rocket sound before the new, less startling, explosion that has turned out very well.
Lastly, I added a couple sounds from one of Stalintc's excellent mods and did some editing on the missile launch sound. Thanks to Stalintc.
