An addition to the aim command:
aim at
(face/head/abdomen/left leg/etc)
This would aim your first shot/slice/pickaxe swing at the body part given. Whether the first strike actually hits would be a factor of combat stats and whatnot, but the attempt would be first at this point.
That way, if you want to jam your weapon in somebody's gut, you can do it and actually hit them there. Or if you really want their knees to rattle, aim at face/head/GROIN!
Aiming at a smaller body part would have a lower chance of success. Easier to hit abdomen than head for sure.
