Samantha's Lullaby

Samantha's Lullaby is a song found in the Zombies Mode of Call of Duty: Black Ops and Call of Duty: Black Ops II. It was composed by Brian Tuey. It first appears on the loading screen for the map Moon.

It next appears as an Easter Egg in Nuketown Zombies, being activated by finding three teddy bears scattered around the map by pressing the "use" button in front of them(on original mode only). One is found on a seat in the bus, one is found in a bed on the top floor of the yellow house, and one is found outside the fence of the garden in the backyard of the green house.

Its last appearance is in Buried, after the players complete  Maxis 's side of  Mined Games.

Trivia

 * At the end of the composition, Samantha Maxis will say "Shh, Do you hear the voices?".
