Kidneys

Kidneys were a 3e hit location found in Basic Set 3e B248 and GURPS Martial Arts 3e pg 49
It was harder to hit than vitals (-4 instead of -3) and could only be targeted from the back.
omitted in 4E, closest approximation is Vitals. Only thing more specific is Heart for vampire in horror
It was only targeted from rear similar to Spine in 4e.
It works like normal hits to vitals, but is an extra -1 to hit and crushing attacks are able to hit it and get x1.5.
In 3e it wasn't possible for crushing attacks to hit vitals, so this allowed something to that effect. There's no value in taking the extra -1 to hit for non-crushing attacks.
4e MA137 sort of restored the location with new rules for vitals, explaining how crushing attacks can target them from BOTH directions:
*solar plexus from in front
*kidneys from behind
"Side" is left out so it's not clear if crushing can target from that angle.
Wounding modifiers in 4e are only x1 not x1.5 though. The purpose to targeting this is, rather than increasing injury, to get a HT roll from shock (at -5 if Major Wound) similar to a Face hit.
