Letter to the Emperor

The Letter to the Emperor is a special item featured in Blackout within Call of Duty: Black Ops 4. It is used to unlock Takeo Masaki as a playable character.

Overview
The Letter to the Emperor can be obtained by interacting with a typewriter found in various Zombies locations around the map, notably the top floor of the Lighthouse, the small office in the Asylum, or the second floor of the Boxing Gym in the town south of Rivertown. When the player obtains the item, they will start the Character Mission to unlock Takeo. The challenge requires the player to reach a placement of fifteenth in Solo, eighth in Duos, or third in Quads. The player must also reach the set placement without using any equipment such as grenades, Barricades, or Mesh Mines. Upon returning the lobby after completing the requirements, the player will be rewarded with Takeo as a playable character.
