Just a quick tip/how to. Title says it all. You can use this method to swap around sounds e.g. grunt birthday party is Index 1526 under projectile_detonation for sound class. We can apply this information to the sniper_fire_reach.snd! to get a birthday sound every time we shoot the sniper rifle.
If you change sounds be sure to copy not only the ugh! values, but the Zone and easy read values as well.
Make backups before modifying your game.
