(adsbygoogle = window.adsbygoogle || []).push({}); GKNOVA6 has been updated recently. At the top left corner you could see a "zombie rockin' hard" that hasn't been there before. So maybe treyarch snuck in a few extra clips for us to find?

It has been there ever since.

I've noticed a few new clips at the top right box.... Thanks for the heads up.

I do recall Carbonfibah saying a few days ago on Twitter that the GKNOVA6 looks different and different videos (he works for Treyarch).
He could just be taking the piss, I can't notice anything

All I see is the same. Helicopter going down, flamethrower on nazi zombies, civilian and scienctists being shot zombies and not zombies etc and tests on humans
