It is unlocked in that video because it was being beta tested! When they beta test everything is unlocked to make sure it's all working properly. I know this because I know Deadybeard. And it's common sense.

TTG_JIMMY wrote ive heard lots of people say its unlocked if you work for infinity ward and that seem's very likely..

It probably is if you work for IW

No, you don't have to be an IW employee to unlock it.

Not yet. It's a long process, still waiting for them to complete it. It technically should be the LAST thing you're able to do

in response to this question:

did your QA guy confirm that you can still get the spinning skull?

Your all going to be like so do you have a pic, a tutorial, etc. BUT THERES NO NEED FOR ONE! While messing around in a splitscreen(Overtime, not in one day) me and my brother earned the Mw2 spinning tenth prestige emblem. Guys all you have to do is get ONE-THOUSAND kills with the AK-47 while "WEARING" the mw2 regular tenth prestige emblem & the 10th prestige title. Want to try to see if im telling the truth...THEN start up a split-screen with these options.
-Unlimited Search & Destroy
-Unlimited Life
-Mini. Health with no Reg. this is not me i found it on game tuts off a mod

Thats acctually make sense couse its ak47 marksman challenge 4 and i cant remember seeing 1 guy who is bothered to use the 10th regular title.. and there are not that many ppl who use ak anyway so i think you guys got it.. well done

I Tried To Find How To Get It But I Didn't Find Any Info

I bet it's going to be unlocked later.

u have to kill IW staff member?
