How To Unlock Every Secret Song Easter Egg | Classified, IX & More

To hear secret Easter egg songs, you must interact with hidden items on the map. There will be no prompt to interact, but there will be a unique sound effect if you interact with the correct item. Find all  items in each area, and the song will begin to play. Check the locations below — the items will always appear in the exact same locations.

[NOTE: Sometimes you’ll have to hold [Interact] to activate the item. Sometimes you’ll need to shoot. Learn what to do with each item below.]


IX – “Mad Hatter” Easter Egg Song

There are four coins you need to shoot to activate the Easter egg song. The coin is small, but glows brightly and has a green-yellow shine. The coin is a different color in each tower.

  • Coin Locations:
    • Coin #1: Danu Tower: Entrance – Look out the window. The coin is on the underside of a wooden staircase on the exterior of the map.
    • Coin #2: Ra Tower: Burial Chamber – In the corner near a burning fire brazier. To the left, there are two chests. The coin is between the chests.
    • Coin #3: Zeus Altar Room – On the side of one of the statue pedestals, right next to the mystery box.
    • Coin #4: Odin Tower: Entrance – Look for a low metal grating. Crouch and look inside (face the entrance from the spawn arena) to spot the coin.

Classified – “Shockwave” Easter Egg Song

There are three Vodka Bottles you need to hold [Interact] on to activate. The bottles are green.

  • Vodka Bottle Locations:
    • Bottle #1: War Room: Lower Level – Down the steps from the Upper Level, go to the back-right corner and look under the terminal.
    • Bottle #2: Central Filing – From the Side Passage door, go all the way to the back and you’ll find this bottle on top of the last row of filing cabinets.
    • Bottle #3: Porcine Research – In the back-left corner of the lab, found below the War Rooms. As you enter, go to the back-left corner to find an open cabinet with a bottle inside.

Blood of the Dead – Easter Egg Song

Instead of finding objects, you just need to input a number in the Citadel Tunnels. Enter the tunnels, at the bottom you’ll find a locked cage with numbers.

Use the Warden’s Key to unlock the cage (dropped from the Brutus zombie boss) and the charged Spectral Shield Spectral Blast to power-up the numbers. Now, interact with each number to change it.

  • Number Inputter Easter Egg:
    • Input 1-1-5 into the three numbers at the bottom of the Citadel Tunnels to activate the secret song.

Voyage of Despair – Easter Egg Song

Just like in “IX“, you need to find and shoot four coins. Each coin has a different color. All you have to do is locate the coin and shoot it to unlock the secret song. Here’s where to find them.

  • Coin Locations:
    • Coin #1: Forecastle – On the right side, on the back of a wooden crate, underneath the stairs. Look on the side of the crate facing three barrels in a burning corner.
    • Coin #2: Poop Deck – On the right side (when facing the main ship), look near a giant roll of wire. Look between the roller and the wooden crate.
    • Coin #3: Lower Grand Staircase – On the floor with the Pack-a-Punch pedestal, look up at the ceiling. Face the staircase and you’ll find the coin on the brown wooden beams on the ceiling.
    • Coin #4: Sun Deck – Look on the rescue boat that’s filled with luggage. The red coin is visible on this boat.
