Who's Who

Who's Who is a Perk-A-Cola in Call of Duty: Black Ops II in the Zombies game mode. It was first introduced in Die Rise and it costs 2000 points. The perk allows players to revive themselves after they are downed - if downed, the player will take control of a zombie, as a clone of himself, that can be used to revive the player's downed character or any other downed player in the match. The double will spawn close to, but not near enough to see the player's body and will only have a Colt M1911. If both the original player as well as the clone are down simultaneously, then their teammates will need to revive both in order to revive the downed player. In case of the player's body being killed in an action such as falling down an elevator shaft, the player will respawn again in the default spawn room with no perks and the M1911, maintaining their points.

Trivia

 * If the clone is facing the player, the crosshairs will turn red.
 * When the clone is in action, all buildable parts will glow.
 * If the player does not revive themselves after a period of time, their screen will return to normal and the doppelganger will become the "real" player.
