Killstreak

For other reward based systems similar to killstreaks, see Streak.

A Killstreak is earned when a player acquires a certain number of kills in a row without dying.

In the multiplayer modes of Call of Duty 4: Modern Warfare, Call of Duty: World at War, Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty: Black Ops: Declassified, Call of Duty Online, Call of Duty: Modern Warfare Remastered, Call of Duty: Modern Warfare and Call of Duty: Vanguard, the player is given various rewards depending on how long the killstreak lasts. Most killstreaks provide air support or another firearms platform, but some, like the UAV, SR-71 Blackbird, Counter-UAV and the EMP can help the user's entire team by giving or blocking radar.

Killstreaks are nowhere to be found in Call of Duty: Modern Warfare 3 and Call of Duty: Ghosts; instead they have been replaced by Pointstreaks. In Call of Duty: WWII, streaks are earned by kills instead of score if the player equips the Blitzkrieg basic training.

Killstreaks are also in Call of Duty: Heroes, but contrary to their name, are not earned by getting a killstreak.

List of rewards

Call of Duty 4: Modern Warfare & Modern Warfare Remastered

Kills Required	Killstreak Reward	Description
3	Radar	Deploys a UAV to scan the maps for 30 seconds and reveal enemy locations. Enemies with the second tier perk UAV Jammer will not be detected by the UAV.
5	Airstrike	Call in 3 aircraft to cluster-bomb a targeted area of the map.
7	Helicopter	Deploys an attack helicopter, either an AH-1 Cobra or Mi-24 Hind (depending on which team the player is on), to engage enemy players for one minute. It can be shot down with RPGs, launched grenades, or concentrated gun fire.

Call of Duty: World at War

Kills Required	Killstreak Reward	Description
3	Recon Plane	Deploys a recon plane to scan the map for 30 seconds and reveal enemy locations. Enemies with the second tier perk Camouflage will not be detected.
5	Artillery	Calls in eight artillery shells to strike a designated location. Player will experience shellshock if close to where the shells are landing.
7	Attack Dogs	Calls in a pack of vicious dogs for one minute time. If dogs are killed, more spawn. Friendly dogs appear as tan and black German Shepherds, enemy dogs appear as solid black German Shepherds. In core game modes, two bites from a dog are required to be killed.

Call of Duty: Modern Warfare 2

In Modern Warfare 2, players can choose up to three killstreak rewards they can earn, rather than just the standard three. At the start, the player can only use UAV, Care Package and Predator Missile, with the option to unlock one new killstreak at each of the following levels: 10, 15, 23, 35, 47, 51, 55, 59, 63, 66, 68 and 69 (all killstreak rewards will be unlocked at level 69). When a killstreak of eight or more is activated, a message will notify all players in the match, showing the callsign and the streak being used (except in Hardcore or when the killstreak is a Stealth Bomber being deployed by the opposing team). Even though a Tactical Nuke is announced to both teams, the player's callsign on the top-right corner will only be shown to players on that player's team.

It is worth noting that two killstreaks that share the same killstreak amount cannot be used together, one must be picked over the other. For example, for the seven kills slot the player can use either the Harrier Strike or the Attack Helicopter, but not both, as well with nine kills slot the player can use either the Pave Low or the Stealth Bomber and the 11 kills slot the player can choose from either the AC-130 or the Chopper Gunner.

For controllable killstreaks (Predator Missile, Chopper Gunner and AC-130), if the player is killed while operating the killstreak, the player can continue using the killstreak until it is done and then respawn or enter spectator mode as normal. The only exception to this is Search and Destroy.

Killstreak rewards available in Modern Warfare 2

Kills Required	Killstreak Reward	Description
3	UAV	Deploys a UAV to scan the map and reveal enemy locations. Can be shot down or hit with a Predator Missile or launcher.
4	Care Package	Player must throw a red smoke grenade to mark the location of an air drop package containing a random killstreak or ammo. The package can kill players if it lands on them. Can be taken by anybody. It takes longer for anybody but the user to obtain the package, leaving them vulnerable.
4	Counter-UAV	Deploys a UAV that disables the enemies' radar and renders hostile UAVs useless. Can be shot down or hit with a Predator Missile, alike the UAV.
5	Sentry Gun	Player must throw a red smoke grenade to mark the location of an air drop package containing an M134 Minigun configured as an automatic M5 sentry gun. The same rules for the care package apply. A single slash from a knife or gunfire will disarm it. Has a 90 second time limit. It can be temporarily disabled by a flash or stun grenade.
5	Predator Missile	Fires a single controllable AGM Hellfire from a Predator Drone. The user is vulnerable on the ground while using/controlling the missile.
6	Precision Airstrike	Initiates an airstrike on a targeted area much like the Airstrike in Call of Duty 4. The user can control the direction from which the airstrike comes.
7	Harrier Strike	Deploys a small airstrike from two Harriers followed by one that will hover over the designated area and attack enemies with its under-mounted turret. Can be destroyed. Will disperse rockets and destroy enemy helicopters as its primary target if there are any in the sky. This will also leave the player vulnerable on the ground until they deploy the harrier.
7	Attack Helicopter	Deploys a Hind or Cobra attack helicopter armed with a single machine gun that flies around the map and attacks enemy players. Can be destroyed. Non-Flyable.
8	Emergency Airdrop	Deploys a C-130 cargo plane that drops four Care Packages. Crates can be stolen, but C-130 cannot be destroyed. Is not affected by an EMP (though it cannot be called in during an active enemy EMP).
9	Pave Low	Deploys a Pave Low armed with two Miniguns. It has a single flare for defense against missile launchers that lock targets. The Pave Low is essentially a better version of the Attack Helicopter. Can be destroyed.
9	Stealth Bomber	Deploys a B2 Spirit that is invisible to the enemy's radar. The bomber carpet bombs a specific line, designated by the player. Cannot be destroyed. Players can experience shell shock when near their own or an enemy's bomb explosions and survive (the only time a player experiences it in multiplayer).
11	Chopper Gunner	Deploys an AH-64 Apache or Mi-28 Havoc attack helicopter, armed with a 25mm cannon, controlled by the player on the ground. The player can be killed on the ground, but, can still finish the session in the chopper. Can be destroyed.
11	AC-130	Deploys a Lockheed AC-130 gunship controlled by the player on the ground. It is equipped with a 25mm Gatling gun, 40mm cannon and a 105mm howitzer, each with an infinite amount of ammunition, but with reload times. The user is vulnerable while using the gunship. Can be destroyed by a launcher or a predator missile. Immune to regular guns. It has 2 flares meaning at least 3 rockets must be shot.
15	EMP	Deploys an electromagnetic pulse that destroys enemy killstreaks and disables enemies' HUDs, mini-map and electronic attachments, such as Holographic Sight. Also disables already deployed equipment, but those deployed after EMP will not be affected.
25	Tactical Nuke	Calls in a nuclear strike that detonates after 10 seconds, killing all players that are spawned at the time the nuke goes off on the map and ending the match in favor of the nuke user's team, regardless of the current match score or time left (except in Free-For-All, in which the player with leading points still wins). The player gets points for the deaths of the enemies killed.

Call of Duty: Black Ops

Radios are used to call in most killstreaks in Black Ops.

Black Ops features a similar customizable killstreak reward system to Modern Warfare 2. All killstreak rewards are available for purchase, via CoD Points, at rank 10. Kills from killstreak rewards don't count towards higher killstreaks unlike previous titles, which means that players must kill the required number of enemies themselves. Also, the Tactical Nuke has been removed.

Sharpshooter

An entirely different killstreak system is used in the Sharpshooter Wager Match game mode. In Sharpshooter, going on a killstreak earns the player perks. Gaining a perk does not cause the player to lose another perk.

Call of Duty: Modern Warfare 3

Call of Duty: Modern Warfare 3 replaces killstreaks with Pointstreaks. The M.O.A.B., at 25 kills, is the only killstreak in the game.

Call of Duty: Black Ops 2

Call of Duty: Black Ops 2 uses killstreaks only in the Sharpshooter Party game mode. Scorestreaks are used in other modes. In Sharpshooter, going on a killstreak earns the player perks. Gaining a perk does not cause the player to lose another perk.

Trivia

General

• In Call of Duty: World at War, there originally was a Fourth Killstreak.
• In Call of Duty: Modern Warfare 3 and Call of Duty: Ghosts, the pointstreaks are sometimes called killstreaks instead.

Call of Duty: Modern Warfare 2

• If Predator Missiles from both the enemy team and the friendly team are in the same place, the icon in the minimap will be shown as yellow.
• Killstreaks were originally divided into categories and players could select up to three of them.
• There are chatter sounds for a Little Bird killstreak. However, this killstreak is cut from the final game. Also, chatter sounds for enemy Predator Missile, Sentry Gun, and Airstrike can be found in game files, but they're not used.
• If one switches teams on a private match after having earned a killstreak without using the killstreak first, the player will lose the killstreak.
• Killstreaks are still destructible after a match ends, meaning if the player fires a rocket or AC-130 guns at an enemy aircraft, one can still get points if the match ends before the rocket/round hits.
• In the Modern Warfare 2 Official Strategy Guide, in the Multiplayer section, there is a picture of a Tactical Nuke referred to as "Nuclear Strike", with a photo of a mushroom cloud instead of a radiation logo. In that same picture, the Predator Missile goes by the name "Hellfire".

Call of Duty: Modern Warfare

• If the player is in the Allegiance team and calls for a Gunship, the pilot will say, "Rhino 2-3 on station. Death from above." The line references to the Call of Duty 4: Modern Warfare mission Death From Above.
• The Advanced UAV is based on the B-2 Bomber.
• Pilots who man killstreaks such as the VTOL Jet, Precision Airstrike, et cetera have specific voice lines on certain situations such as confirmed kills with a successful airstrike, or if they are taking enemy fire.
• If the player is in the Coalition team and calls for White Phosphorus, the pilot will say, "This is Striker 3-1. Dropping Whiskey-Pete (or Whiskey-P) on your mark." This is a spin-off of the World War 2 term for white phosphorus, Willie Pete.
• Operators have unique voice lines when calling for any killstreak.
• Cruise Missiles can be destroyed with a Trophy System, and can be blocked by a Riot Shield.
• A player can pilot a Cruise Missile and can crash it into a VTOL Jet or a Gunship, earning unique Boss Fight points.
• VTOL Jets can have different camos, ranging from having no camo to a jungle digital camo.
• Care Packages can be hit with launchers when mid-air, pushing them away from the map.
• A Chopper Gunner can be marked for a Precision Airstrike.
• The Advanced UAV is visible to all players when it is deployed. It can be targeted with launchers having IR systems, but it cannot be shot down.
• VTOL Jets cannot target enemies if they are in smoke.
• If a VTOL Jet has locked on a target, its shots can penetrate plywood and sheet metal.
• Gunships and Chopper Gunners have thermal imaging.
• The Gunship pilot will announce if ammunition for any armament is ready for use.
• When controlling a killstreak, players can hear the Operator breathing as they use the control pad to man the killstreak.
• Players who are controlling manual killstreaks can be killed (which even includes getting executed). However, this doesn't stop the player from using the killstreak and they are notified by the distinctive "death" sound effect.
