[MA] Game terms for these kills
 

Okay, so this video (http://youtube.com/watch?v=FGjMjFNhFrg) [spoilers for the video game Dishonored, violent content] shows some kills with a melee weapon - the fencing sabre I believe?

So if you wanted to pull off these moves in GURPS, presumably according to Martial Arts guidelines, break down the manoeuvres and combat options used turn-by-turn.

I think one of the last ones involved a Reverse Grip thrust which left the sword in (Turn 1), followed by a torso grapple to the stunned target (Turn 2), followed by a quick contest to spin the target's facing (MA118, Turn 3), followed by an All-Out Attack (Double) to grapple the neck with both hands (Turn 4), followed by a Neck Snap to kill the target over another two or so turns (Turns 5-6?), and finish with a Ready to pull the sword back out.

first kill:

crit on swing attack to arm, maximum damage causing it to be severed.

followed by a grapple to the neck.

followed by a sword thrust to vitals, its just a special effect that he went through the neck down into the chest to stab the heart.

As regards the weapon, I'd call it too substantial to use the Sabre stats from the Basic Set. I'd call it mid-way between that weapon and the Cavalry Saber. In my campaign, I'd call it a sw cut; thr+1 imp weapon weighing 2.5 lbs., with MinST 9 and usable with Broadsword, Saber or Shortsword skills. Essentially, a slightly longer Shortsword or a light hunting sword/hanger, just at the breakpoint between Shortsword and Broadsword.*

It's not got a fancy guard or anything, so a basic version of it shouldn't cost more than $500. Game balance might require us to call it $800, as it's a very flexible weapon. If one wanted, one could demand a Weapon Adaptation Perk to use it with Saber, which would mean that a cost of $450** would be more than enough.

*Which it is somewhat ridiculous to split into two skills anyway.
**It's a larger Shortsword or a smaller Cavalry Saber. A cost mid-way between the two seems eminently fair.
