(adsbygoogle = window.adsbygoogle || []).push({}); Did yall notice in the afghan walkthrough video the perk 3 slot for the ump .45 had a perk called ninja which makes you invisible on heartbeat sensors! So that means that with a silencer and cold blooded will be the ultimate stealth class. OMG!

Well what about Dead Silence? Wonder what slot that is

but what does it do for sound i can still hear your footsteps and doesn't that perk scramble the radar then ill know your around the area

Ninja can't be for that purpose. Cold blooded doesn't show you up on ANY heat seeking/sensor thing,ninja must be something else.

Also,I saw 'anger close' but it's exactly the same as sonic boom,just increase explosive damage.

Look at the freakin video it says undetectable on HEARTBEAT SENSORS

He is right on that. Ninja makes you undetectable on heart beat sensors. Cold blooded protects you from thermal sights and most air-based killstreaks (chopper, uav, etc)

Like shadow said "Danger Close" is also confirmed in that video as well as a another "new" perk called Sitrep which is said to be "like bomb squad but cooler" Which isn't possible cause Bomb Squad is the best perk ever
