Perks

Perks are modifiers featured in the multiplayer aspects 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 (Nintendo DS) and Call of Duty: Modern Warfare 3 that passively affect game play, allowing further customization of classes. They affect available equipment, effectiveness of the player's equipment, the usefulness of the enemy's equipment, and the physical properties of the player's character.

Call of Duty 4: Modern Warfare Perks
Some perks are available initially while others are unlocked as the player progresses through multiplayer ranks. Up to three perks, one of each tier, can be equipped at one time. The tiers are color coded blue, red, and green and therefore only one of each can be equipped.

Call of Duty: World at War Perks
Like in Call of Duty 4: Modern Warfare, the perks are divided into equipment, weapon and ability tiers.


 * Vehicle perks, Shades, Iron Lungs and Reconnaissance are not available on the Wii version of Call of Duty: World at War.

Call of Duty: Modern Warfare 2 Perks
In Call of Duty: Modern Warfare 2 the perks are divided into tiers in different ways than in Call of Duty 4 and World at War. Along with standard perks, players will now be able to unlock improved "Pro" versions of certain perks by fulfilling certain requirements while using them. These "Pro" versions include the original abilities of the perk, but also add new benefits. Many of the perks that were in Call of Duty 4 or 5 that are missing are now either part of a Pro perk, available as weapon attachments, or are now deathstreaks, such as Deep Impact (FMJ), Bandolier (Scavenger Pro), and Martyrdom. The Overkill perk has been replaced partially by the inclusion of Machine Pistols, Shotguns, and Launchers as secondary weapons and also by the One Man Army and Bling perks. Interestingly, if a Perk Challenge IV is achieved mid-game the "Pro" version will take effect immediately for all classes equipped with that perk. However, the effect of the Pro version is granted after respawning. Up to three perks, one of each tier, can be equipped at one time. The tiers are color coded blue, red, and green and therefore only one of each can be equipped.

Call of Duty: Black Ops Perks
All Perks are unlocked for purchase at level 4. Unlocking Pro Perks requires three sets of challenges (related to the standard version) to be completed, as well as the purchase of the ability for 2000 CoD Points and the 3000 cost for the upgrade to its pro version. The appearance of the pro perks are done in a similar fashion to the ones in Modern Warfare 2, where the background becomes a star with the perk graphic superimposed over top of it.

First tier perks designate player appearance and provide constant passive effects. Second tier perks enhance weapon performance. Third tier perks can be either active or passive and are generally more context-sensitive than first tier perks. The perks featured in Black Ops are as follows. On Black Ops, the pro challenges relate to the effect of the pro. For example, Marathon, the challenge is "Sprint 26 miles using Marathon" and the pro is unlimited sprint.

Trivia

 * In Call of Duty 4, the Tier 1 perks originally appeared after Tier 3 perks.
 * In Call of Duty 4 and Call of Duty: World at War, it is possible to empty the player's Tier 1 perk slot by attaching a grenade launcher or a grip to a weapon and then removing it.
 * Tier 1 perks in Call of Duty: Black Ops affect the user's player appearance.
 * There were rumors on the internet of a "monkey man" perk on Call of Duty: World at War, allowing the ability to climb trees, although there has never been any evidence of the perk. This rumor likely started because someone climbing a tree in this video can be seen:
 * The monkey man perk was even more convincing after a glitch on Makin was found, allowing the player to jump on top of a tree.
 * If a player unlocks the Pro version of a Perk in Call of Duty: Modern Warfare 2, the Perk will change automatically during the game and so the player will not have to change the perk in the Create-A-Class menu. In Black Ops however, the player has to buy it.
 * Pro perks all have stars as the background of the perks icon, superimposing the graphic on top of it.
 * If watching someone in the Killcam in Call of Duty: Modern Warfare 2, the text by each perk will not say that the perk is Pro unless the killed player has the Pro version of each respective perk. However, the pictures have the star background showing that the perk is pro.
 * Call of Duty: Black Ops for the Nintendo DS is the first Nintendo DS Call of Duty game to feature perks.
 * A glitch was found for getting Cold-Blooded Pro, in which if a helicopter is shot down by bullets causing it to spin down, every bullet that is shot into the falling helicopter will count as a killstreak destroyed. In order for this to work, the player must have Cold-Blooded while shooting the falling helicopter. This is demonstrated in this video: &#91;2&#93;
 * Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, and Modern Warfare 3 are the only Call of Duty games to feature Pro versions of perks.
 * In World at War, Tier 1 perks were originally green-colored. The green color for early World at War perks is brighter than color of Call of Duty 4 Tier 3 perks. Also, the bright green color was used for cut squad perks such as All Seeing Eye and Commanding Squad Leader.
