Copycat

Copycat is a death streak perk in Call of Duty: Modern Warfare 2, that enables a player to copy the class of the last person to kill them after dying four times in a row (three times with Hardline Pro) without getting a kill. To activate the Deathstreak, the player is to press the weapon switch key during the Killcam. The killer is then notified that the player has copied their class.
