Out of interest: There are many mods available with custom animations, mostly sex-related. I really have no clue about how these modders could do that, so I have to ask: Is it more work to create some unarmed (= martial arts) moves, like kicks or even flying kicks and some typical stances? Would it be hard, to make a "true" unarmed fighter, who doesn't even need these claws, knuckles and gloves?
