In Blackout, go to the top floor bathroom in the Asylum and flush the toilet furthest to the left. The game will then play “Lullaby for a Dead Man,” a song that shows up repeatedly throughout the Call of Duty series.
Blackout contains numerous references to Element 115, which is the cause of the Zombies in Zombies mode.
In the diner in Blackout, interacting with the jukebox will play several songs from the series, including the TranZit loading screen music. Three other songs are also played. The jukebox will play one of the four available songs whenever you interact with it.
On the Hacienda map, there is a body wrapped up and chained to a brick that you can find underwater.
The Mystery Box teddy bear in Zombies will sometimes move its body.
On the Contraband map, you can find a volleyball meant to be a shout-out to the volleyball Wilson from Castaway.
On the Nuketown map, there are many mannequins. If you shoot off all of the heads of the mannequins within two minutes, a rocket will lift off and then explode to disperse mannequin zombies.
Secret coordinates in Operation Absolute Zero actually point to the real-world location of Treyarch, the company that developed the game.
On the IX map in Zombies mode, if you shoot 4 special coins located in four different areas of the map, the game will play the song “Mad Hatter” by Avenged Sevenfold.
