Hit Location

:"Hey big guy, that wobbly left knee? It's the first thing I'm going for." - Lexi, Blood and Treasure: The Lunchbox of Destiny
Hit Location are penalties to hit smaller parts on a body.
==Penalties==
The penalties are as follows. Italicized ones are for non humanoid creatures:
Location 	Penalty	Nullifying AdvantagesInjury Tolerance
Eye 	(-9) 	No Head (maybe); No Eyes
Skull 	(-7) 	No Head
Face 	(-5) 	
Right/left Leg/ArmForeleg, Mid Leg, Hind Leg	(-2) 	No Arms, No Legs, No Limbs
Torso 	None 	
Groin 	(-3) 	Unusual Location per Alien Nation
Hand/Foot 	(-4) 	No Arms, No Legs, No Limbs
Neck 	(-5) 	No Head
Vitals 	(-3) 	Homogenous;
== Grappling ==
Martial Arts, p.68 seems to take the "greater penalty" interpretation when discussing Targeted Attack:
Grapples use half the usual hit location penalty, round towards a larger negative number: 
* -1 for Arm or Leg
* -2 for Hand or Foot
* -3 for Face or Neck, etc.
Some confusion might have been generated for how it works with strikes:
* the fighter can buy off up to half of his default penalty (round up) for a strike,
The direction of rounding is given in an example:
*Defaults to Boxing-5; cannot exceed Boxing-2.
In this case "half" of the default penalty is rounded "up" just like B400 and in this case, up is towards 0.
*extremity reduces from -4 to -2
*limb reduces from -2 to -1
==Basic==
370:
:To grab another body part, apply half the penalty given under Hit Location (p. 398) to your roll; see
Grappling and Hit Location, p. 400.
400:
:Halve hit location penalties (round up) if you are grappling a body part – it’s easier to grab a body part than to strike it. This does not apply to grabbing a weapon!
This may read confusing to some people who might think "up" means a greater penalty, when sometimes "up" for negative numbers is toward zero: a lesser penalty.
The way rounding "up" is discussed on MA68 implies you move it towards 0, although the example of being -3 for Face/Neck disagree with it.
==Technical==
Pg 5 of GURPS Martial Arts: Technical Grappling for example mentions:
*The modifier can be improved up to the grappling penalty, but not more than that; e.g., when punching the skull, you could spend up to 4 CP to improve the
hit location penalty from -7 to -3
TG implies you round the penalty "up" in the positive direction (toward 0) meaning a lesser penalty, since -3.5 becomes -3 and not -4, unless that is a typo.
It appears to work like a temporary "Targeted Attack" when discussing halves and not like a grapple's idea of half, even though both say to round up.
== Trivia ==
* There seems to be disagreement on which way to round the "halving" of hit location penalties. Just use the larger negative number.
