crap i forgot, wait it tells you in the game lol.
just go to cold blooded and look it should say unlocked at this level.
You unlock cold blooded pro by destroying 40 killstreak rewards with cold blooded on, which are things such as; helicopters, harriers, turrents, and maybe care packages, not sure about the care packages.
Cold blooded perk is in tier 2 and is unlocked at level 25
At level 25 you receive the Cold Blooded perk. When you are using this perk, no enemy aircraft, killstreaks or thermal scopes / uavs can see you.
you punch yourself in the face 5 times and then throw your console out the window and it should pop up saying you unlocked it, your welcome!
Normal Cold Blooded - Not shown in white on thermal scope, not spotted by enemy air support, not shown on UAV (except for when you shoot without a silencer) Cold blooded pro - No red crosshair or name shown when being targetted directly at. Cold blooded pro comes with cold blooded you get both parts of cold blooded when you are pro
The UAV shows enemies on your in-game map as red dots unless they have the perk cold-blooded on.
All you need to do is create a class with coldblooded equipped with an at4 and a light machine gun
Yes.
a trout is a cold blooded creature.
Modern theorists agree they were warm blooded.
It is just like cold-blooded pro in COD: Modern Warfare 2. Your name will not be red to an enemy, and there will also be no crosshairs. Not only that, chopper gunners and all of that cant kill you.
