Ninja

Ninja is a Tier 3 Perk featured in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty Online, Call of Duty: Black Ops Cold War, Call of Duty: Vanguard, a Tier 1 perk in Call of Duty: Black Ops 6, a Gun perk in Call of Duty: Infinite Warfare, and a Boot in Call of Duty: Modern Warfare III.
==Call of Duty: Modern Warfare 2==
Ninja makes its debut in Call of Duty: Modern Warfare 2. Users are not detected on the Heartbeat Sensor attachment.
The Pro version of this perk is unlocked after players kill 50 players in "close-quarters" while using the perk. The pro version reduces the movement noise volume (footsteps, mantling and climbing) by 75%, effectively replacing Dead Silence. The actual distance that constitutes "close-quarters" needed for the challenge is unknown, but it is approximately the range at which the Tier 3 Perk Scrambler completely Scrambles the radar of enemies - Scrambler Pro is unlocked similarly by making "close-quarters" kills. It also may be the distance at which a Heartbeat Sensor can detect players.
This is useful to players who like going lone-wolf and sneak behind enemy lines. A complete custom stealth class often comprises silenced weapons, Cold Blooded Pro as their Tier 2 Perk (no red cross-hairs when aimed upon), and Ninja Pro (silent footsteps are needed) as their Tier 3 Perk. As mentioned in Dead Silence, though it removes all "high-profile" movement (sprinting, climbing onto an obstacle/platform) noise, a player can imitate this quiet manner by moving while crouched or in ADS (aiming down the sight).
Ninja is most useful in games such as Sabotage and Search and Destroy as players with Heartbeat Sensors often wait by the objectives (or people using headsets or even alert hearing), but it is often useless in other game types due to the rarity of Heartbeat Sensors.
==Call of Duty: Black Ops==
Ninja returns as a Tier 3 perk in Call of Duty: Black Ops. It is roughly equivalent to the Dead Silence perk from past Call of Duty games and shares effects with SitRep Pro in Modern Warfare 2.
===Overview===
Ninja reduces all player noise by 75%. Its pro version completely silences the player and doubles the volume of enemy sounds. Teammates without Ninja will be heard normally by the player.
Unlike in past Call of Duty games, Ninja Pro is not limited to footsteps alone. Ninja Pro silences falling, mantling, weapon switches, equipment deployment, and more. It also more than doubles the sound of enemy footsteps, as well as amplifying enemy callouts, reloading, and equipment deployment. It is useful to know the language of the player's team to distinguish friend from foe.
The November 18th patch balances audio levels making player noises much easier to detect. This makes Ninja and Ninja Pro much more useful. However, even with Ninja Pro, enemies do not make nearly as much movement noise as they do in Call of Duty: Modern Warfare 2. The volume of footsteps varies widely depending on the ground surface; on some surfaces footsteps are nearly silent. Additionally, while sprinting on some surfaces footsteps seem to make noise only every third or fourth step, again minimizing the usefulness of this perk. Another shortcoming of the Pro version of this perk is commonly found in Hardcore game modes or any game mode which disables the minimap by default. A group of friendly players within close proximity to the user of the perk can make distinguishing footsteps and other sounds emitted by hostile opponents difficult to identify and lead to confusion and a false sense of security
Ninja Pro seems to let the player pick up on enemy footsteps from slightly further away but not necessarily louder. Having a line of sight definitely lets the player hear the footsteps easier than if the player is around a corner.
Even with Ninja Pro, players will hear themselves mantling. This may be so that the player isn't playing in an awkward silence.
The 1.04 patch further adjusts Ninja Pro:
"Additional sound mix tuning for Ninja Pro users – increased ranges and volume of enemy footsteps, and removed player footstep sounds on concrete material types."
===Pro Challenges===
*Silenced Kills – Get 150 kills using the Suppressor attachment.
*Back Stabs – Get 5 Backstabber Medals.
*Plants – Plant the bomb 10 times in Demolition, Sabotage, or Search & Destroy.
==Call of Duty Online==
Ninja makes a return in Call of Duty Online as a Tier 3 perk, allowing the player to be undetectable via the Heartbeat Sensor and Thermal Scope as well as decreasing the effect of Recon.
It costs 2500 GP or 2680 CP to purchase and use.
==Call of Duty: Infinite Warfare==
Ninja is a Legendary gun perk in Call of Duty: Infinite Warfare. It grants the player the perk Dead Silence whenever the player is airborne or wallrunning. In Zombies, the player will be hidden from zombies temporarily after firing the last shot of the weapon's magazine.

==Trivia==
===Call of Duty: Modern Warfare 2===
*Even with Ninja Pro, players will still make a loud crunching sound when falling from an elevated height, just like its predecessor Dead Silence. Players with Ninja Pro will also make noise if they move through branches or bushes.
*Ninja Pro actually reduces footstep sounds to a quarter of their original volume, but this is still extremely quiet and will almost never be heard.
*SitRep Pro has no effect on Ninja Pro.http://twitter.com/fourzerotwo/statuses/9606073705 Players using SitRep Pro will not be able to hear Ninja Pro users more easily than players who are not using Sitrep Pro.
*Friendlies using Ninja do not appear on Heartbeat Sensors.
*Dead Silence was originally going to be an ability of one of the four planned multiplayer character abilities. However, the character models were scrapped and it was added as the Pro ability of Ninja.http://fourzerotwo.com/post/688644283/deadsilence Robert Bowling's website showing concept art for a stealth class as well as its origins
*When the player earns the pro version, the effect will not work until their next life.
===Call of Duty: Black Ops===
*The achievement, Stand Down, uses the same Ninja logo.
*The last challenge for getting Ninja Pro, which is planting 10 bombs, is absent in Combat Training, since the player cannot play bomb related gametypes, such as Search and Destroy and Demolition.
