What is your favorite hit location mechanic?

We pretty much just roll on a weighted table.

Explain

Not that user, but I'd assume a percentage table where things like "body" or "leg" are more likely results than "head"

Nechronica:
roll 1d10
1~5 is a miss
6 is where ever the one taking the damage chooses
7 is legs
8 is body
9 is arms
10 is head
11+ is where ever the attacker chooses.

Does these system uses hp for each hit location?

or what effects they have for attacking an special place like the head?

I like the Savage Worlds called shot rules. They're simple to manage and there's no dealing with a random table.

I like it as well, I've even implemented it in other games.
I know in some games it adds penalties based on what's hit. Mythras/Runequest, if I recall, does in fact have HP for each location.

I like Burning wheels. Defender decides where he'll get hit (usually the armored part), attacker can spend extra successes to move hit to another location.

ORE, because it elegantly makes it part of the attack/damage roll.
