Call of Duty Black Ops 4 Classified Zombies - Easter Eggs Guide, How to Play the Shockwave Zombies Song

Here's your complete guide to Call of Duty: Black Ops 4 Zombies mode, including overviews of the Voyage of Despair, IX, and Blood of the Dead maps.

Back when Call of Duty: Black Ops 4 first launched last year, it debuted with the Classified map as the sole DLC map for the Zombies mode. In this Black Ops 4 Classified Zombies guide, we'll be walking you through everything there is to know about the debut DLC map for Zombies, including a list of all the various Black Ops 4 Classified Zombies Easter Eggs, and much more.

But if you instead need anything else to do with the Zombies mode in the latest iteration of Call of Duty, you can head over to our Call of Duty: Black Ops 4 Zombies guide. It's on this main page that you can find a complete overview for the three other maps in the game: XI, Voyage of Despair, and Blood of the Dead.

Black Ops 4 Zombies Classified Map Guide

As we mentioned at the top, the Classified map for Call of Duty: Black Ops 4's Zombies mode is locked behind the Black Ops Pass. You can purchase the pass on PC, PS4, or Xbox One, and it'll set you back by right around $49.99. Included in the pass, you'll get four Zombies maps, one of which is Classified.

Classified is actually a remake of "The Five" map that originally featured in Call of Duty: Black Ops, a fair few years ago. It's been redone for Black Ops 4, but the layout of the map remains largely the same.

But, if you think you can play as John F. Kennedy like you would have in the original version of the map, think again. The characters have all been replaced for Classified, and this time we'll be playing as Tank Dempsey, Nikolai Belinski, Takeo Masaki, and Edward Richtofen. As always in Call of Duty's Zombies mode, no characters have an advantage over any of the others, and the differences are purely cosmetic.

To kick things off, there are three total floors in the Classified map. You start off in the top floor, which is your general office area. From there, you can take the elevator down to the war room, where you can find the Mystery Box pictured just below, and from there you can take another elevator down to the laboratories.

The Classified map is definitely the smallest map available in Black Ops 4 at launch. There's very little room for error, especially on the lower floors, so make sure to stick together with the rest of your teammates, if you want to make it to the higher rounds.

Zombies Classified Easter Egg Song

As with basically every Zombies map in Call of Duty Black Ops 4, there's a special song that you can trigger to start playing. To unlock the Shockwave song on the Classified map in Black Ops 4, you'll need to find and interact with three vodka bottles around the map, the locations of which can be found just below.

  • Vodka Bottle 1 - Found in the lower level of the war room. Down the stairs, go to the back right corner of the room, and look underneath a terminal.
  • Vodka Bottle 2 - From the central filing corridor, find the side passage door, go all the way to the back of the room, and you'll find the bottle on top of some filing cabinets.
  • Vodka Bottle 3 - In the back left corner of the porcine research lab, you can find this bottle just below the war rooms.

Zombies Classified Crooked House Easter Egg

Recently, in early November, a huge Black Ops 4 Zombies leak unearthed several brand new easter eggs. You can see one of them just below, which takes place in the morgue area of the Classified map.

The video below expands on the initial tweet. You'll have to turn on the power first, and then flip a few more switches, if you want to see the easter egg in full.
