Questions about Nat. 20's, Critical Hits, and Deathblows

[The Oh So Amazing Nate]

The game is taking place in a TMNT setting. So please, if you could use rules found in SDC books.

1. When making a successful critical strike the damage is doubled. But is that damage applied against SDC or HP?

2. When declaring a deathblow and succeeding, does the opponent A.) Automatically drop dead? or B.) Take double damage directly off of HP?

3. When making a called shot to a vital area with a ranged weapon and succeeding, what happens to the opponent? (Example, I shot an NPC between the eyes 2x with a bow and arrow (1d10) from a concealed spot (Sneak attack does 2x damage right?). The guy didn't
die! So I shot him in the chest with another arrow and he was still alive!.)

SDC first, HP only when all SDC is depleted.

2. When declaring a deathblow and succeeding, does the opponent A.) Automatically drop dead? or B.) Take double damage directly off of HP?

A) used to be the rule, but it was later changed in more recent books and printings to B.

3. When making a called shot to a vital area with a ranged weapon and succeeding, what happens to the opponent? (Example, I shot an NPC between the eyes 2x with a bow and arrow (1d10) from a concealed spot (Sneak attack does 2x damage right?). The guy didn't die! So I shot him in the chest with another arrow and he was still alive!.)

No, sneak attacks do not deal extra damage. the only benifit is they cannot attempt to dodge or parry sneak attacks. there are optional rules for shots to the head and heart (deals half damage to HP as well as full damage to SDC), but that's explicitly an optional rule, so your GM isn't "wrong" for disregarding it.

Sad but true fact is as the rules stand there's no benifit to making called to flesh-and-blood creatures that don't have seperate SDC values for different parts of their body. Not unless your GM uses "common sense" regarding it.

1. A Critical Strike does damage to S.D.C. first, and then Hit Points when that is depleted.

2. In the original TMNT rules, a Death Blow is an automatic kill. The opponent drops dead unless they Roll successfully, in which case their current S.D.C. and Hit Points are reduced by half. More recent rules from other books state that a successful Death Blow does double damage direct to Hit Points, and a successful Roll by the opponent means Hit Point damage is reduced by half.

3. The effects of called shots to vital areas are left to the discretion of the GM.

Edit to Add: I see Nekira posted while I was typing. Please excuse the repeated information, as I said virtually the exact same thing she did.

The group I play with uses the pointblank head/heart table (Rifts Conversion Book 1, page 17) for additional effects of a called shot to a vital spot.
