Cold-Blooded is a Tier 2 Perk featured in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops II, Call of Duty: Black Ops: Declassified, Call of Duty: Advanced Warfare, Call of Duty: Black Ops III, Call of Duty: Infinite Warfare, Call of Duty: Black Ops 4, Call of Duty: Mobile, a Tier 1 perk in Call of Duty: Modern Warfare, Call of Duty: Vanguard, a Tier 3 perk in Call of Duty: Black Ops Cold War and a Bonus Perk in Call of Duty: Modern Warfare II. 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.

Trivia[]

General[]

  • Creatures that are used as the perk icons, like lizards, snakes and scorpions, are cold-blooded, so they are immune to thermal sights.

Call of Duty: Modern Warfare 2[]

  • When killed by a controllable killstreak (Predator Missile, AC-130, Chopper Gunner) the killcam will depict players being killed incorrectly, as it shows a red square around the player's body, even though they would not appear with the square on their monitor normally.
  • Teammates with Cold-Blooded won't appear white on a thermal scope.
  • If players shoot down two Harriers with one Stinger missile and is still going for Cold-Blooded Pro, the two Harrier kills will only count as one.

Call of Duty: Black Ops II[]

  • Teammates, with or without Cold-Blooded, won't appear yellow on a Dual Band scope.
