Quoted from shacklersrevenge:oh and p.s, I think I had completed the ballroom but immediately after, I shot in the left scoop and the game shut down! Before I could think WTF? a face appeared in the DMD and SCREAMED so loud that the wife and kids heard it from rooms over. Sorry for the spoiler, but I don't even know what I did to get it, it was awesome though.
That's the random scream mode! Randomly when you get one of the scoops it does it. Can be disabled in the menu but I love it!
