There are other Kamehameha sound mods on this site but I found all of them to be WAAAYYYYYY too loud. So I opened them up in audacity and lowered them to be around the same volume as the Super Kamehameha sound already in the game. This mod only applies to the Ultimate attack sounds and not the Super ones.

Example: Super Kamehameha has the sounds, not normal Kamehameha ect.

If you think this mod is way too quiet and should be louder, then get this one instead.

Video preview contains the old mod, too lazy to record a new one.
