Ala Fallout, Skyrim now has a kill-cam VATS style finishing move camera, so you'll sometimes perform some grizzly animation to kill someone or something.

So, out of all the finishers you've seen, which finisher is the most brutal? You know the one, when you're sat with a friend and you both yell 'OOOOOHHHHH!' after smashing that woman in the knees, then the ribs, then the face, THEN the skull.

For me, the most brutal I've seen is the greatsword against humanoid enemies (bandits/Draugr/human/Elves etc) where you break the leg and slash down on (well, through) the skull. Made me LUL

The one where the enemy is down on their knees and and you behead them where they are.
