When revived, the character will comment with the quote for when an achievement is unlocked or with weapon-specific quotes.The Season 2 challenge for Call of Duty: Black Ops Cold War requiring players to revive themselves 10 times with Tombstone Soda is named "Who's Who?", referencing the combination of the two perks' abilities.

The backing track used for the Who's Who jingle comes from a stock track entitled "Rockabilly Kitty".Who's Who was supposed to appear in Mob of the Dead and Origins.In the song's jingle, towards the end, one can hear the singer cough, and a siren can also be heard.Game files refer to Who's Who as "chugabud".If a Who's Who clone drinks Who's Who, the downed character will die and the doppelgänger will replace the character.All points spent in Revival Mode will be refunded if the player revives themselves.If a dead player spectates someone using a Who's Who clone, that player will hear "Who's Who!" for the rest of the game, as if using Who's Who.It is possible to get another of the same gun with Who's Who.This means that obtaining Random Perk Bottles in solo mode in Die Rise in an effort to obtain more than four perks is potentially dangerous because obtaining Who's Who will cancel out Quick Revive. Who's Who will affect the solo version of Quick Revive, meaning if the player has both Quick Revive and Who's Who when they are downed, they will spawn as the clone, and after a while, Quick Revive kicks in and revives the player.Despite the fact that all equipment is lost upon controlling the clone, including weapons, upon being downed and in the revival mode, Claymores are still able to be used.After getting revived by the doppelgänger, the player will lose their Monkey Bombs.When the clone is in action, all buildable parts will glow.If the clone is facing the player, the crosshairs will turn blue.The second method uses the Time Bomb instead Who's Who. This is one of two methods that can be used to double the points in the Bank and fill it to the maximum.Doing so will restore the points the player had to the initial amount, but keep the deposited money in the bank, which essentially duplicates the amount of of points used in the process. Once controlling the doppelgänger, the player has to deposit the points in the bank, and then revive the player's body. Who's who can be used to earn "free" points with the Bank: After obtaining a large amount of points, the player has to get downed near the bank.In Call of Duty: Black Ops Cold War, while not physically in the game, the perk's attributes are combined with Tombstone Soda which turns the player into a shadow in the Dark Aether armed with their weapons when downed, allowing the player to revive themselves. In case of the player's body being killed in an action such as falling down an elevator shaft or off the map, the player will respawn again in the default spawn room with no perks and the M1911, maintaining their points. In solo mode however, being downed as the doppelganger counts as the death of a player, thus ending the game. If both the original player as well as the clone are down simultaneously, then their teammates only need to revive the original player body to save the downed player. The double will spawn close to, but not near enough to see the player's body and will only have a M1911. If the player does not revive themselves before they bleed out but is still alive as the doppelganger, they will become the doppelganger but will lose all perks and equipment leaving them with only the M1911. Perks and weapons can be bought while playing as the doppelganger.

The color of the perk is dark blue(sometimes seen as teal or turquoise), and the icon is two hands reaching for each other. If players successfully revive themselves or if another player revives them, they will keep all perks and equipment they had before they got downed apart from Who's Who. If downed, the player will take control of a doppelganger that can be used to revive the player's downed character or any other downed player in the match. The perk allows players to revive themselves after they are downed. Who's Who is a Perk-a-Cola in Call of Duty: Black Ops II in the Zombies game mode, first introduced in Die Rise.
