Call of Duty Season 5 is live, and the big update added the final Zombies map for Black Ops 6. Just like the previous maps, Treyarch has included a secret Easter egg song to discover, and here we’ll guide you through finding the items needed to unlock the hidden song unique to Season 5’s Reckoning map.

To play the secret Zombies song on Reckoning, you first need to find three hidden headphones. The headphones are blue and have fuzzy ears like the Mr. Peeks bunny. These can be interacted with in any order and at any time during your match. Press Square (PlayStation) or X (Xbox).

Completing this Easter egg will play the new Zombies song called “Remember Us,” which is performed by Kevin Sherwood and Elena Siegman.

Starting from the spawn room, go up the elevator into the Mutant Research Lab area. The first headphone set is near a dead zombie on the floor. As shown in the image above, the body is near a cryo chamber with a Disciple floating inside.

Continue following the in-game prompts that lead you to Pack-a-Punch. Use the Anti-Grav Personal Launcher to reach Android Assembly in Tower 2.

Take another elevator and progress through the doorway to the Dark Aether Entity Containment area. From here, drop down into the lower section of the room. As shown in the image above, a zombie is sitting in a chair wearing the second set of headphones.

Still following the Pack-a-Punch route, make your way into the Director’s Office. As shown in the image above, the headphones are inside a cabinet on the shelf behind the Director’s desk.

The hidden song, “Remember Us,” will play once you’ve interacted with all three. You can only do these steps once per match to play the song.
