By defintion, shooting someone in the head will do.
3 shots to the body 1 to the head.
The most effective way to snipe someone in Halo 3 is with a headshot. Shots to the head are a one hit kill, while shots to the rest of the body require two hits to kill.
I don't exactially get the question, but I think you mean the Br 4 shots to the head for a kill thing. And yes that does work.
it makes everything on the screen disappear. no gun, no motion sensor, health bar, riticule. good luck with head shots :P
