How to complete Black Ops 6 Zombies Reckoning main story Easter egg

The Reckoning Easter egg in Black Ops 6 Zombies is live and slowly coming together.

It’s more involved than previous releases like the Tomb or Shattered Veil, with layered objectives and NPC events that move across the map. If you want to finish what started on Terminus, this guide will walk you through each confirmed step so far.

Keep in mind this is a work in progress and will be updated as the community uncovers more.

Activate the Pack-a-Punch

The first thing you’ll want to do is activate the Pack-a-Punch machine.

You can follow the objective markers, but we recommend opening up most doors around Project Janus HQ first so you’re not scrambling later.

Unlock the elevator from the Executive Office and descend to Sublevel 10. Here, power up the Particle Accelerator system, then locate and destroy all twelve Aetherium shards nearby. Doing this triggers the Pack-a-Punch to appear.

Get the Gorgofex

Here’s a quick step-by-step breakdown of how to get the Gorgofex:

1. Go to the Mutant Research Lab and check both static monitors. Note the capital letters in the words and form an element.
2. Use the periodic table to find the element’s 3-digit atomic number. If the number is only two digits, add a zero to the front.
3. Enter the code into the keypad in the Mutant Research Test Area. This opens the Bioweapons Lab.
4. Fill the cyst inside with Vermin kills. Then, take the filled cyst to the Quantum Computing Core and charge it with yellow spores.
5. Bring the charged cyst to Dark Entity Containment and start the power surge.
6. Activate all four surge panels to spawn an Uber Klaus.
7. Destroy its shoulder pads and lure it to the panel. Wait for the Forsaken transfer, then kill Uber Klaus.

Inside the T1 Research Lab, examine two monitors: one near the periodic chart and one by the Mangler. Each displays a highlighted capital letter. These letters hint at a chemical element.

Match it to its atomic number using the chart, pad it with a zero if needed, and enter the resulting code in the nearby keypad to unlock the Bioweapons Lab.

Inside, you’ll find a cyst that charges with nearby Vermin kills. Once full, take it to the Quantum Core and interact with yellow spores to energize it.

Then proceed to Dark Entity Containment, trigger a surge, and activate four nearby terminals to summon Uber Klaus. Disable its shields by targeting the shoulders, lead it to the panel, and wait for a transfer before taking it out to claim the Gorgofex.

Start the main story

Now it’s time to get started with the main story. Head to the T1 Mutant Research Lab and interact with the centrifuge.

1. Grab the Syringe, then make your way to T2 Sublevel 10. There’s a floating zombie caught in the Particle Accelerator beam.
2. Jump into the beam to knock it loose, then interact with it to collect the Blood.
3. Return to the centrifuge and place the Syringe back in. A Fowler Mangler will spawn.
4. Defeat it to get a Mutant Injection, which you’ll need to scan near the Dark Entity Containment zone to gain access to the next lab area.

This is as far as we’ve gone when it comes to the main story. We’ll update this section when we’ve gone further.

However, we’ve uncovered some other puzzles that will likely tie in later on.

Franken Klaus puzzle

One section revolves around building Franken Klaus.

1. Collect body parts from Kommando Klaus units by shooting off each arm.
2. Scavenge the left and right legs in T2 Android Assembly. These can spawn:
   • Behind a door
   • On a shelf
   • In a scrap pile
   • Behind a shattered mirror
   • On the floor
3. Once you have all four limbs, attach them to the hanging Klaus in T2 Android Assembly.
4. Then, lure Uber Klaus to the same area and bait its electric attack to strike the hanging body. That will activate Franken Klaus.
5. Franken Klaus will first hack the computer in T2 Teleportation Lab, then a S.A.M. Trial machine, before returning to the Teleportation Lab.
6. Go to the T1 Quantum Computing Core and break the metal container using a melee attack with Melee Macchiato.
7. Carefully deliver the purple brain (you’ll be defenseless while carrying it) to the machine beside Franken Klaus to continue

Folder locations

Scattered across the map are six possible personal items tied to Maxis, each linked to a folder with a different date. Only four appear per match, but we’ve found six folders so far:

• Katana on a desk in T1 Executive Suite
• Wristwatch on a table in T1 Executive Suite
• Combat Goggles near a lamp in T1 Director’s Office
• BND Badge on a desk in T2 Teleportation Lab or a coffee table in T1 Executive Suite
• Notso’s Collar on a desk in T2 Teleportation Lab or a coffee table in T1 Director’s Office
• Scarf on a desk in T1 Director’s Office

Each Maxis item has a number attached to it that changes every game. Using the date on each folder, sort the item numbers in reverse chronological order (from latest to earliest) to form a 4-digit code. Enter this code into the PC in T2 Teleportation Lab.

That’s everything we’ve got for now. We’ll make sure to update the guide as soon as we’ve cracked the unfinished puzzles and tie them into the main story.
