Among the games I've played, such as a knife through the neck, neck snapping, poison, backstabbing and even the use of the piano wire, what is your favorite among the stealth kills?
I personally like the neck-snapping, since its clean, can kill instantly or a painful the by the lack of blood circulation and lack of oxygen, plus doesn't take to much effort especially when the target is caught off surprise, however, if an involuntary move such as the head moving as the same direction of the intentional move then it has no effect.
