Yes, I think there's a problem with the untouchable badge, I am trying to unlock the Tommy Gun but need the untouchable badge to do so. So far I've defeated every family boss in pretty much every zone and I can not find one that counts for the Untouchable badge. I've tried the Marcone, I've tried non Marcone, etc. and good luck finding concrete info on this also, every site that I see conflicts with the other on how to get this badge.
Did they do away with this badge in i14? Because it seems that the Untouchable badge is in deed Untouchable, they should rename it to the Unattainable badge.
