Redfacti0n's gunfire sound's
After playing through SCS a multitude of times vanilla and with other mods. I couldn't help but hate how the guns sounded when I fired them especially the pkm.
So here is my contribution to the mod community. Some of them are made from real gunfire sound recordings while a good majority are fabricated using an audio program. This pack is a matter of personal taste. If you want a bigger oomf coming from your gun this is the pack for you. However if your into silent and lesser volume gunfire sounds then this may not be the thing for you.
If your going to edit this in anyway or add this to another mod just be sure to give me credit.
