I'm ripping the voice files from the game right now, and I found a voice that I just don't recognize. I know it doesn't belong to the playable characters, so it must belong to a boss or someone else that you fight. But the only three people I know who are voiced that you fight are...
So does anyone here remember if there was any other voiced characters that you fight?
EDIT: I don't know if it'll help any, but
here are the voice files just in case you might recognize the character's voice.
