Since its release in Call of Duty: Black Ops Cold War, Firebase Z has proved to be a hit among the Call of Duty community.
Alongside the main Easter Egg quest, players have managed to discover a song that starts playing.
Here's how to activate the Firebase Z Easter Egg song.
Firebase Z Easter Egg Song Walkthrough
To activate the song, players must find cassette tapes that can be found in various locations around the map.
Before beginning the search, ensure that the power is already turned on.
The first tape is located in the spawn village, above the Pack-A-Punch machine on the first floor. It's placed against a set of books on a shelf.
The second tape is also located in the spawn village, inside the building next to Quick Revive. The tape will be nestled away in another set of shelves.
The third and final tape that needs to be found is at the outpost. Make your way through the teleporter and head right. The first room you come across will contain the tape. It's on the ground next to a green filing cabinet.
Once you've grabbed the third tape, the song will begin to play.
