Kino der Toten: Samantha’s Sorrow

The song

Samantha’s Sorrow is a song by Brian Tuey, first heard on Gorod Krovi. On Kino der Toten (Black Ops III) it is the musical Easter egg added by the remaster, next to the song «115» of the original. It is started by a short hide and seek with a doll of Samantha Maxis, and finishing it also drops a Max Ammo.

The blue metal door of the Alley under a small canopy, in a brick wall above a pile of planks, Kino der Toten, Call of Duty Black Ops III Zombies

The blue door

A metal door painted blue, in a brick wall of the Alley next to a wire fence. The raps come from behind it.

Step by step

Go to the Alley and stand by the blue door. A series of raps is heard behind it, in three groups that form a number of three digits.
Hit the door with the knife the same number of times, group by group. If the answer is right, a new series of raps plays.
Answer three series in a row. A sound confirms the success.
Go to the theater. A doll of Samantha has appeared on a pile of rubble to the left of the stage, by a blinking light. Interact with it.
The doll now hides somewhere in the theater, playing a small lullaby. Find it and shoot it, then do the same at each new hiding place.
When the last doll is gone, go back to the rubble and interact with the doll, now spinning. A skeleton arm comes out of the ground and takes it, and the song starts.

The raps can follow several patterns:

1-1-5
1-2-1
1-4-3
2-4-1
3-2-1
5-1-2
5-3-4
6-2-4
6-6-6
9-3-5

Where the doll hides

On the back of the large house prop on the stage, on a wooden board.
Behind a metal grate in the ceiling next to the stage, near the trap between the stage and the Dressing Room.
On the balcony above the first doll.
On top of the chandelier of the theater.
On a seat in the aisle of the theater.
On the upper balcony at the back of the theater, on top of a light.
In the Pack-a-Punch room.

In the First Room

The Alley and the theater are behind the doors of the Lobby, so the song cannot be started in a First Room game. The song «115» cannot either: only one of its three rocks is in the Lobby.
