Here's 2 ideas that I had for Fatalities floating around my head--but they would both probably make the game so violent that it would be banned....maybe.
Doesn't matter who does these, so, I'll use Kabal as a reference.
FIRST: Kabal walks up to his opponent and sinks either his fingers or his hookswords into the center of the top of the skull. He then pulls his hands or swords to the sides resulting in the vertical slice thing--but this time making it a rip. The brain pops out first, then the organs as you hear the bones split while the body is ripped in two.
Second: This one is less complex. Kabal thrusts a hand into his opponent's stomach and pulls out a length of intestine. He keeps pulling out intestines until he feels resistance...then swings the opponent around by the intestine and smashes the body against a nearby wall.
What do you all think?
