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 Copycat, killed player should press the weapon switch key when they are either seeing their character die or during the Killcam. A killer gets notified that somebody copied their class.
If a player kills a person using a class that the person copied off the same player, the player gets the emblem of the Copycat symbol and the title ID Thief.
Using Copycat grants the player everything that was in their killer's class, regardless of whether or not the player has it unlocked yet. This includes perks, attachments, camouflages, guns, and equipment. If the thief has not got the stolen perks to the Pro version, they will not receive Pro perks through Copycat. However, if player has Pro perks and used Copycat on a player that was using the non-Pro versions, then they will be upgraded for the copycat.
Note that the associated challenges for weapons, perks and equipment do not unlock until the equipment itself unlocks, so while copying a higher-ranked player's class may allow access to more gear, it also prevents players from improving their regular loadout, as kills players make with unavailable weapons are effectively being "wasted" rather than completing weapon challenges.
- Copycat's first icon was a black cat (hence the name) instead of a thief.
- Copycat will work until its user has killed someone and has re-spawned.
- Copying the class of someone using the One Man Army perk and subsequently using One Man Army to switch to another class will cause the player to keep respawning with the copied One Man Army class.
- If the player copies an enemy class and gets team-killed (in Hardcore game modes) then they will respawn with the same copied class.
