Interesting. I guess I'll hold off, for now.
It's a shame, because there really isn't a great beat-em up solution on the Asset Store yet. (Though Invector's third-person controller templates are excellent for making a Dark Souls clone right out of the box, I'm looking for something a little smoother... and hopefully something that treats the skinned mesh as something you can freely swap out and edit without needing to rebuild everything every time.)
