Solved1 Hit kill zombies code

Hello there,

I'm looking for a code or someone that can code a 1hit zombie kill. You get a free smile :-) and a thanks for it.
And If I find the code or already have it, how to activate it and put it on crossfire?

(this is just a friend of Xblaster12 on his account, otherwise i would ask him ^^ )

Thanks
