Returning from previous installments in the franchise, the Zombies maps in Call of Duty: Black ops 4 hide songs that can be triggered by completing a task particular to the map. Of course, while there is plenty to do on each map such as completing a rather difficult Easter egg to unlocking a certain Wonder Weapon, many would be remiss to not know how to unlock these songs.

While the steps for each are listed below, it's worth mentioning each map has its own song in Black Ops 4. IX, for example, features "Mad Hatter" by Avenged Sevenfold, and Classified's Easter egg song is "Shockwave" by Elena Siegman.

IX

In order to unlock this IX Easter egg song, players will need to find and shoot four coins hidden around the map. The particular order is of no importance, but the following locations each hide a coin: Danu Tower Entrance, Ra Tower Burial Chamber, Zeus Altar Room, and Odin Tower Entrance.

The Danu coin is hidden near one of the zombie windows on the underside of a wooden staircase. The next coin, hidden in Ra Tower, is located in a corner near the fire brazier. It'll be stealthily hidden between two chests residing next to the brazier.

Attached to the base of a statue, the Zeus coin is simple enough to find, as the aforementioned statue is right next to a mystery box spawn. The Odin coin is inside a metal grate seen when facing the entrance to the Arena spawn.

After shooting each of these coins, players will get to enjoy Avenged Sevenfold's "Mad Hatter."

Voyage of Despair

To unlock this Easter egg song works in a manner exactly like IX's. Black Ops 4 players will be tasked with finding and shooting coins located in the Forecastle, the Poop Deck, the Lower Grand Staircase, and the Sun Deck.

The first coin, hidden under the right side of the stairs in the Forecastle, will be attached to the back of a wooden crate. The Poop Deck coin will be found between a large roll of wire and a wooden crate on the right side of the ship.

On the Lower Grand Staircase, player swill find this coin on a broken wooden beam by looking at the ceiling above the staircase. The final coin is on the Rescue boat filled with luggage on the Sun Deck.

Blood of the Dead

Although this song is a bit more involved than the last two, it is not that much difficult. Players will need to insert the numbers 115 into the number pad in the Citadel Tunnels. To do so, first obtain the Warden's Key by defeating Brutus.

Then, find the parts and build the Spectral Shield. Once this done, go to the bottom of the Citadel Tunnels and use the aforementioned items to unlock the number pad.

Classified

The final Easter egg song requires players to find and interact with three green bottles across the map. They are found in the following locations

  • War Room - found in the lower level, players will need to look underneath the terminal in the back-right corner.
  • Central Filling - Enter this location from the Side Passage door, continue straight back, and the bottle will be found on the very top of the last row of filing cabinets.
  • Porcine Research - This bottle will be found in the open cabinet in the back-left corner of the Porcine Research lab.

Without a doubt, players will likely want to trigger these songs when they can, as they certainly add to the zombies aethestics. Even though they play no major role in the main Easter eggs, these little nuggets are one of the reasons Zombies is loved so much.

Call of Duty: Black Ops 4 is available now for PC, PlayStation 4, and Xbox One.
