In Call of Duty: Black Ops Cold War Zombies, there are many new easter eggs. One of which is the hidden song Easter Egg. The newest map, Die Maschine, follows an old pattern of allowing players to collect items in-game that once completely found, plays a song during their zombies round. For Die Maschine, there are three tapes scattered around the map. Collecting all three plays, "Alone" by Kevin Sherwood.

The order in which players collect the tapes does not matter, so long as all three tapes are located and collected, the song will still play.

There are three places on Die Maschine where tapes will spawn. One is in the Medical Bay, up the stairs on a storage rack. A second tape will spawn in the Particle Accelerator room. If you're facing the Pack-A-Punch machine, it's too the right on top of some control panels. The third tape can be found in the remains of the old zombies map "Natch Der Untoten" in the Living Room. The tape will be on the tipped over shelving unit.
