Complete Guide to All Major Black Ops 6 Zombies Easter Eggs

Why I Needed a Real Guide to BO6 Zombies Easter Eggs

After dozens of hours (and more fails than I care to count), I finally managed to complete every main Black Ops 6 Zombies easter egg myself. From Wonder Weapon blueprints to secret songs and way-too-tricky side missions, every quest feels like its own dark puzzle box. If you’re tired of chasing rumors or getting stuck on a step with a clueless squad, here’s exactly what works-and what to avoid-on Reckoning, Shattered Veil, The Tomb, Citadelle des Morts, and Terminus.

Before You Start: What You Actually Need

• A solid team or willingness to solo grind (most quests are way faster with 3-4 players)
• Pack-a-Punch unlocked ASAP
• Prioritize loadouts with boss-killing potential (Wonder Weapons change everything)
• Save at least 1 Explosive weapon and Rapid-fire gun per player for boss encounters
• Don’t forget headsets-many secrets need audio cues or hearing dialogue triggers

The rest comes down to map knowledge (which this guide will deliver), calm mid-round thinking, and willingness to fail a few times as you perfect each step.

Reckoning – Main Quest & Easter Egg Song

This is the “big one”—easily the most complex quest in the BO6 launch set. The first couple of runs, my team and I lost hours running in circles, either failing boss mechanics or missing a random lab key. The breakthrough for us was careful inventory management (don’t let anyone die with the Key Card!) and relentless note-taking for puzzles.

• Must-do Steps:
  1. Obtain blood sample from Sublevel 10.
  2. Kill Geneticist special zombie for Key Card and DNA Vial.
  3. Defeat Fowler Mangler & get Mutant Injection (unlocks Teleportation Lab).
  4. Locate and decipher SAM Files for the Lab computer.
  5. Puzzle: Use Periodic Table to crack Mutant Lab door code—took us ages, so use screenshots or write it down.
  6. Charge cyst in Test Area, then power via Quantum Core.
  7. Grab brain, deposit in Teleportation Lab.
  8. Trigger containment room power surge and beat Uber Klaus (careful—his minions wreck unprepared squads).
  9. Build Gorgofex Wonder Weapon—this gun is critical for later steps!
  10. Rebuild Klaus, grab orb from Sublevel 10 for the Teleportation Lab.
  11. Get and clean the fungal head for the portal.
  12. Unlock Vacuum Seal Devices, collect and use them on purple floating objects.
  13. Return to Lab, insert devices to activate portal, ready your squad, and face the boss.

Common Pitfalls: Don’t let anyone die holding key quest items—they vanish if you wipe, forcing a full restart. Communicate drop points and guard the quest carrier. Also, Uber Klaus’s phase two hits harder than expected—rotate train routes and save special ammo.

Easter Egg Song: Headphones are found in the Mutant Research Lab, lower Containment Room, and Director’s Office bookshelves. Interact in any order (best between rounds so you don’t get mobbed) and enjoy the track once you activate all three.

Shattered Veil – Mastering the Ray Gun MK II & Song Unlock

This quest took us the most actual time—each Ray Gun MK II variant requires separate canister hunts, crafting, and tests. My advice: split up after Pack-a-Punch to maximize canister gathering, but always rejoin for boss fights. Solo is technically possible but agonizingly slow.

• Key Steps:
  1. Kick off with Pack-a-Punch, then chase down the Ray Gun MK II itself (usually from box/lucky drops, or quest if unlucky).
  2. Gather three upgrade canisters (random spawns—look behind elevator, conservatory shelves, and tunnels for efficiency).
  3. Craft and test Ray Gun MK II-W (wipe out elemental zombies), then move to MK II-R (rapid-fire challenges), and finally MK II-P (precision kills/patrols).
  4. Each questline leads to its own mini-boss or wave—save Wonder Weapon ammo for these or you’ll risk wipes.
  5. After all variants are done, battle the Z-Rex boss (massive health pool—coordinate nukes and damage/specials).

Easter Egg Song: Three headphones—conservatory box (north-east wall), metal shelving by elevator, and service tunnel corpse. Trigger the third to start the song, and plan for a “safe” round so your team won’t be caught off-guard when everyone gets distracted by headbanging!

The Tomb – Navigating Puzzles & The Staff of Ice

The main quest here is deceptively short, but the boss is brutal and the constellation puzzles stumped us for two runs. Here’s what I wish I’d done the first time:

• Quick Route:
  1. Find Subterranean Temple and “Doorway to Nowhere”—look for glowing symbols on walls/ground.
  2. Obtain Monocle (often tucked near altars or statue feet).
  3. Destroy enough purple crystals to light up constellation puzzles—shoot with upgraded weapon to save ammo.
  4. Shoot correct constellation symbols—watch for the ones that “shimmer” briefly.
  5. After solving, craft Staff of Ice from pieces in tunnels and shrine (toughest enemy spawns here—pull out traps or grenades as backup).
  6. Shoot specific rocks/crystals with Staff in both normal map and Dark Aether. Use the Monocle to see required marks.
  7. Follow glowing orb, use Ull’s Arrow for elite enemies, then prepare for the hardest final boss in the launch set (bring everything—specials, monkey bombs, Pack-a-Punched Ray Gun, etc).

Easter Egg Song: Headphones at shrine statue feet, in Dark Aether Nexus left of entry, and in the Ossuary by the skeleton. The track only triggers once per game, so time wisely if you want to flex in front of squadmates.

Citadelle des Morts – The Toughest (But Coolest) Questline

This was where my squad lost the most attempts—mainly to the length and number of “fetch” steps that need tight timing. Make sure everyone knows their next objective at all times and only trigger Rituals once all are ready.

• Main Steps:
  1. Enter castle, defeat basement Doppelghast, activate Pack-a-Punch.
  2. Talk to Krafft (always triggers progression, don’t skip him).
  3. Gather Page Fragments, Ritual Items, and wax seal stamps—split up to speed things up.
  4. Activate Bastard Swords by solving mini-puzzles—refer to paintings and nearby hints.
  5. Complete Item Rituals and Incantations (multi-step, so don’t be afraid to “waste” a zombie round stalling for everyone to be ready).
  6. Repair book, solve puzzle, charge Mystic Orbs—this often took us several tries since orbs spawn enemies in swarms.
  7. Trigger final encounter—save power drops (Insta-kill, Nuke) for this phase.

Finishing the quest unlocks new Weaver skin and a special calling card. If you finish pre-Directed mode patch, you get exclusives not available later—my squad was thrilled after barely making the cut.

Song Unlock: Headphones in tavern (table), east castle gate, and Undercroft couch (look for the giggling sound).

Bonus: Chess Piece Guardian & Bartending Minigame

– Chess Piece: Find in a random shelf or table, drop onto board in Sitting Room, survive three purple-zone zombie waves (kill inside zone only—time it at start of round for max spawns). Completing this spawns a temporary Knight Guardian ally, clearing out zombies.
– Bartending: Gather liquor bottles (Sitting Room, Undercroft, Dining Room), then serve zombies at tavern’s end bar. Each correct serve is 100 Essence, and finishing gives you a free PHD Flopper! Zombies can’t hurt you during the event (but resume as soon as it ends).

Terminus – Boss Hunt, Mega-Stuffy, and Song

This is the fastest “linear” quest but packed with surprises if you explore every corner. Patient 13 (last boss) almost wiped my solo run—use every revive, and don’t cheap out on box rolls for Wonder Weapons.

• Quest Steps:
  1. Craft Beamsmasher (parts hidden in Engineering/Mining—watch for glowing interactables).
  2. Deliver hard drive to Peck, get codes for Nathan’s containment, defeat Nathan for key card.
  3. Network fix: essentially a short escort mission. Guard the device.
  4. Hack buoys (timed—send fastest player on your squad).
  5. Defuse bombs (Quick Revive Perk helps if you get caught short).
  6. Fight Patient 13—keep a zombie alive between boss phases to manage the clock and ammo.

Rewards: Maya skin and Terminus calling card on quest completion. XP bonus felt pretty significant too—I gained an entire tier after my first clear.

Easter Egg Song: Headphones outside Engineering (wire coil), Mining Tunnels (barrels), and Bio Lab office. Activate for “Can You Hear Me?” and flex your discovery skills.

Mega-Stuffy: Interact with six stuffed toys across the map (not just for fun—completing this lets the Mega-Stuffy revive you or a squadmate, saving a run from disaster!). Take note: return the toys to their beds in Living Quarters for the quest to finish.

What I Learned (And What You Should Always Remember)

• Never hoard key items—share between squad so a single down doesn’t mean an instant fail.
• Don’t rush major puzzles, especially codes & ritual steps; one missed clue means a frustrating restart.
• Easter egg songs are great to complete on “safe” rounds, ideally when you can clear the map and chill for a sec.
• Take screenshots of codes and puzzle solutions—my early runs failed from bad memory or poor note-taking.
• When soloing, always leave a slow zombie to avoid getting caught in mid-step menus/puzzles.

Summary and What to Tackle Next

If you work through each map one at a time (I recommend Reckoning or Shattered Veil for starters), you’ll find the hardest part is managing squad mistakes and those relentless boss encounters. Keep these step-by-steps handy, and remember—cheesy as it sounds, every wipe is a learning experience. You’ll crack the code eventually, and the unlocks, songs, and bragging rights are honestly worth every puzzle solved and every revive shared.
