In Call of Duty: Modern Warfare perks are modifiers that appear in the multiplier modes of the game and passively affect gameplay. Perks also allow further customisation of classes and affect available equipment, the effectiveness of your equipment, the speed your equipment can be used, and the usefulness of the enemy's equipment, and the physical properties of your character.
