"Extreme Hangman"? Now I've heard everything. Actually, when you think about it Hangman's a pretty extreme game as it is. When you get a letter wrong,
a human bodypart is hung in a gallows with the end result being that you have a doodled human corpse hanging quite dead at the end of the game if you fail. Hell, if you really look at it it's a pretty graphic game if you win as well. "Hey, you're free! Oh, you're just a disembodied head...

).To get much more "extreme" than that you'd need Rockstar to make it.
