actually, some games have done this. i think psi ops was one of them
basically they blend the position of the ragdol with the animation for the character to get back up again. not too sure if that's how it's done, but i know there's some kind of keyframe blending in there.
i'd love to get a pair of robotic arms so i could scare little kids.
or walk up to people and say that i am a terminator sent back in time, and tomorrow is judgement day.
they had an xbox on them - as if that's not considered to be a weapon. if you can actually manage to pick the thing up, surely you could launch it at someone. now that's pain.
