Hidden Perks?

[beanbag1992]

Hey guys, i was just wondering to any of you have any information on the hidden perks like the quick revive and deadshot daquari? I myself have permanent quick revive but I still dont know how i got it. Spiderbite has a video of him getting permanent deadshot and the explanation most people are giving is that you need to get 2 headshots with 1 bullet. But after trying this for some time and getting countless double headshots and even some triples i still dont have it. There is also rumours going around that after 200 explosive kills you get perma flopper but i too have tested this one out and it doesnt seem to be working.

The deadshot-like perm you'll know you have because no matter where you shoot a zombie their head explodes. So if you really want to test it get down to one last zombie, and keep shooting the lower body or just anywhere that isn't the neck or head area. If the head explodes you got it, if not keep trying.

I do know when I saw my flash of light for the deadshot-like perk I didn't get a double headshot, I killed a crawler to finish the round. So I really don't know if there are different ways to obtain it but I do know that I killed a crawler with a headshot using the 3 round burst pistol from the bus when the flash of light appear for that.
