'''Cold-blooded''' is a Tier 2 perk appearing on ''[[Call of Duty: Modern Warfare 2]]'' that makes players undetectable to all killstreak rewards and thermal imaging. Players using Cold-Blooded will be invisible to the [[UAV]]s, [[Sentry Gun]]s, [[Harrier]]s and computer controlled Helicopters and simply will not be targeted. With [[Predator Missile]] Strikes, [[AC-130]] and [[Chopper Gunner]]s, players using this perk will still appear on the screen but they will not be highlighted by a red square. Thus, the best strategy during one of these kill streak attacks is to simply stop moving as the black and white resolution for such attacks is poor and moving objects are much easier to see. Viewed through thermal scopes instead of appearing bright white, Cold-Blooded players will appear as shades of gray similar to the environment, However this may cause the player a disadvantage on snow maps, as the gray has more contrast with the environment, whereas the white-hot non-cold blooded players are much harder to spot against the white snow. As they are not truly invisible, moving Cold-Blooded players are much easier to spot through thermal scopes than stationary ones. As most Thermal Scope users are more accustomed to bright white blots on the map, it is easy to pass right over a Cold-Blood user.

'''Cold-Blooded''' is a Tier 2 [[perk|Perk]] featured in ''[[Call of Duty: Modern Warfare 2]]'', ''[[Call of Duty: Black Ops II]]'', ''[[Call of Duty: Black Ops: Declassified]]'', ''[[Call of Duty: Black Ops III]]'', ''[[Call of Duty: Infinite Warfare]]'', and ''[[Call of Duty: Black Ops 4]]'', and is a Tier 1 Perk in ''[[Call of Duty: Modern Warfare (2019)|Call of Duty: Modern Warfare]]''. It prevents the player from being highlighted by [[thermal scope]]s, and has several other benefits which vary by game.
The Pro version prevents the red name and crosshairs from appearing on an enemy's screen when they are looking at the user. It is unlocked by destroying forty enemy killstreak rewards (of any kind, even UAVs) while using this perk. If a silencer is added this is very helpful to sniper classes (though damage is reduced). Just as in the original Modern Warfare in which silencers and the [[UAV Jammer]] perk were mixed.

Instead of appearing as bright white silhouettes through a [[Thermal Scope]], Cold-Blooded players will appear as shades of gray similar to the environment, either friends or foes. This may actually cause the player to be at a disadvantage on snow maps, as the gray has more contrast with the environment, whereas the white-hot silhouette of non-Cold-Blooded players is much harder to spot against the white snow (of course, for this reason, most players choose not to use Thermal Scopes on winter maps, so the issue is often resolved). As they are not truly invisible, moving Cold-Blooded players are much easier to spot through Thermal Scopes than stationary ones.

*One of the most efficient ways to utilize this perk is either in [[Search and Destroy]], or&nbsp;with an Anti-Support class. As an Anti-Support class, unless a friendly is next to you, or an AC-130&nbsp;is taking pot-shots, they will not attack you, letting you both unload your magazine and rockets without the threat of immediate annihilation from the&nbsp;vehicle above you.In Search and Destroy, when coupled with [[Bling]] and [[Ninja]], you become almost invisible to all but direct sight. Unless the enemy has [[SitRep]]&nbsp;Pro you can sneak up to anyone and give them a quick tap-out with your trusty knife.
 
*With this perk it is not safe to stand next to someone without it during an enemy killstreak. They will be targeted and you may be killed with them&nbsp;when they are hit. However, in friendly fire games, you will be safer, as the average player&nbsp;will not attack players without red boxes since they will assume that you are friendly. Because of this, players trying to shoot down enemy aircraft with Cold Blooded should stand away from team-mates.

Experienced players use the Pro version in order to play dead, often for "Ninja Defusing", or just to fool enemies who may have hurt them. By going prone, and repeatedly pressing the weapon swap or "cooking" a [[Stun Grenade|Stun]], [[Flash Grenade|Flash]], [[Smoke Grenade|Smoke]] or [[Semtex]] grenade, it will appear as if the player is dead to others.

Once the Pave Low has been destroyed shoot at it as it is falling out of the sky. For every bullet that hits the Pave Low, it counts as 1 kill. It is quite possible to get 30-60 'kills' towards the challenge this way for every one Pave Low.

Cold-Blooded is a Tier 2 Perk featured in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops IICall of Duty: Black Ops: Declassified, Call of Duty: Black Ops IIICall of Duty: Infinite Warfare, and Call of Duty: Black Ops 4, and is a Tier 1 Perk in Call of Duty: Modern Warfare. It prevents the player from being highlighted by thermal scopes, and has several other benefits which vary by game.

Call of Duty: Modern Warfare 2

Cold-Blooded's primary ability is used for the avoidance of killstreak rewards - it allows the user to be invisible to all forms of air support. The vision for Chopper Gunners, AC-130s and Predator Missiles show players with the Perk active, but does not highlight them with a red outline square. Cold-Blooded users can also be killed by collateral damage from other killstreaks, for instance standing between a user of a different tier 2 Perk while a Sentry Gun is firing upon them.

Instead of appearing as bright white silhouettes through a Thermal Scope, Cold-Blooded players will appear as shades of gray similar to the environment, either friends or foes. This may actually cause the player to be at a disadvantage on snow maps, as the gray has more contrast with the environment, whereas the white-hot silhouette of non-Cold-Blooded players is much harder to spot against the white snow (of course, for this reason, most players choose not to use Thermal Scopes on winter maps, so the issue is often resolved). As they are not truly invisible, moving Cold-Blooded players are much easier to spot through Thermal Scopes than stationary ones. As most Thermal Scope users are more accustomed to bright white silhouettes on the map, it is easy for them to pass right over a Cold-Blooded user.

The Pro version prevents the red name and cross-hairs from appearing on an enemy's screen when they are targeting the user. It is unlocked by destroying 40 enemy killstreak rewards while using this perk. The perk is essential for the "ghosting" tactic, and the Pro version can assist in doing so.

Experienced players use the Pro version in order to play dead, often for "Ninja Defusing", or just to fool enemies who may have hurt them. By going prone, and repeatedly pressing the weapon swap or "cooking" a Stun, Flash, Smoke or Semtex grenade, it will appear as if the player is dead to others.
