If you're wondering how to complete the Shattered Veil main quest Easter Egg in Black Ops 6 Zombies, we can help you out. Shattered Veil is a new map that was released with the Season 3 update and continues the storyline from the "The Tomb" main quest.
At the end of The Tomb, the team — Maya, Weaver, Carver, and Grey — obtained the Sentinel Artifact. Now, they've come to meet S.A.M. and figure out how to activate it, with the ultimate goal of bringing back Samantha Maxis.
This guide provides a step-by-step walkthrough to help you complete the Shattered Veil main quest Easter Egg in Black Ops 6 Zombies.
How to complete the Black Ops 6 Zombies Shattered Veil main story Easter Egg
At the start of the match, you spawn in the Garden Pond just outside the mansion. During the initial phases, you'll receive guided instructions until you reach the Pack-a-Punch Machine. After that, you're on your own. With no further in-game guidance, you'll need to figure out the next steps yourself.
Trending
That's where this guide comes in, providing all the necessary information to help you complete the Shattered Veil main quest.
Investigate the mansion
Your first objective is to investigate the mansion. To get there, choose one of two available routes (like in other BO6 Zombies maps); both lead to the same area. As you progress, you'll encounter closed gates that require Essence to unlock. Eliminate some zombies, gather some Essence, and open the gates.
After opening the third gate, proceed into the Banquet Hall located beneath the mansion. Here, you'll find a non-functional elevator.
Get the Fuse from the maintenance worker
To activate the elevator, head to the Library, which will be marked on your map. Climb the ladder, and you'll encounter a zombie dressed as a maintenance worker wearing a helmet. Eliminate it to obtain the Fuse.
Destroy Richtofen's computer to get the Circuit Board
With the Fuse in hand, go to the Director's Quarters, where you'll find a computer next to a tall CPU cabinet. Look at the top part of the cabinet to spot a blinking red light. Shoot it, and the Circuit Board will drop. Collect it.
Repair the elevator
Return to the Banquet Hall area and locate the non-functional elevator. Go to the back of the elevator and interact with the in-game prompt to repair it. Hold the button for a few seconds until the repair is complete. Once done, the elevator will work.
Call the elevator
Call the elevator, but be ready because once the doors open, multiple zombies will emerge that you must eliminate quickly. Then, the elevator will break and fall.
Take the zipline to S.A.M.
Go over to the broken elevator, and a prompt will appear asking you to descend. Take the zipline down.
Investigate the Mainframe Chamber
After reaching the lower level, you'll find S.A.M.. Proceed inside and head to the upper platform to spot the Pack-a-Punch Machine.
Get the Ray Gun Mark II
To obtain the Ray Gun Mark II, you'll need to complete a series of steps.
1) Find and collect the Floppy Disk
You can acquire the Floppy Disk on or after Round 10 while in the area you accessed after taking the zipline. Fight zombies in this region until you encounter one with purple glowing eyes. Eliminate it, and it will drop a Floppy Disk. Make sure to collect it, as no other zombies will carry this item.
This is where the main mission starts, and you won't find any guided information hereon.
2) Use the computer in the East Foyer
Next, head to the Grand Foyer, where the large dinosaur skeleton is located. From there, enter the East Foyer (the chamber to the right). In the northwestern corner, you'll find a computer, interact with it.
Beside the computer, a printer will slowly generate a document. Wait a few seconds for it to print, then interact with it to retrieve a four-letter uppercase code (e.g., "MOTH").
3) Decrypt the code in the Nursery
To decrypt the code, go to the Nursery, where the PhD Flopper Perk-a-Cola machine is located. Once there, look for a blackboard on the west side of the room.
The blackboard is divided into six segments, each containing multiple letters. Your goal is to determine the corresponding numbers for each letter in your code.
Find each letter on the board and note how many letters are in its segment. For example, if "MOTH" is the code, then:
- "M" is alone in its segment - 1
- "O," "T," and "H" are in a segment with 8 letters - 8
- This means the code is 1888.
4) Enter the code in the Service Tunnel
Return to the Service Tunnel, the same area where you first found S.A.M. Inside, you'll see a Doppelghast trapped inside a glass cage with a keypad beside it. Interact with the keypad and enter the four-digit code (e.g., 1888).
Once you input the code, the cage will open, and the Doppelghast will attack. Eliminate it to receive the Severed Arm item.
5) Acquire the Ray Gun Mark II
With the Severed Arm in hand, head to the Supply Depot, where the teleporter is located. Inside, you'll find the Armory, where the Ray Gun Mark II is stored. Interact with the panel, and you can now acquire this powerful Wonder Weapon.
Once you've acquired the Ray Gun Mark II, you need to upgrade it through specific steps. There are three upgrade variants:
- Ray Gun Mark II-W
- Ray Gun Mark II-P
- Ray Gun Mark II-R
Each upgrade requires you to find ritual items and complete a sequence to power up the Sentinel Artifact. Its better not to upgrade all three versions at once—instead, upgrade one at a time and complete its corresponding steps before moving to the next.
Before upgrading, you must collect three Empty Canisters, which are essential for the process.
Collect the three Empty Canisters
1) First Empty Canister
For the first canister, you need to obtain an LT53 Kazimir. You can find a free one on a zombie body in the Service Tunnel, near the destroyed truck in the debris. Alternatively, craft one using Salvage at a Crafting Table.
Once you have the Kazimir, head to the Rear Patio, just behind the Double Tap Perk-a-Cola machine. You'll see a zombie spawn window, and inside, a canister will be visible. Throw the Kazimir just at the bottom of the window. The vortex will pull in the canister, and once the effect ends, you can collect it.
2) Second Empty Canister
The second canister is hidden inside one of four large crystals scattered across the map:
- Southwest Balcony
- Conservatory
- East Foyer
- Service Tunnel
To retrieve the canister, you need to shoot each crystal with the Ray Gun Mark II until you find the right one. The location is random, so you may discover the canister in the first crystal you destroy or in the last one.
3) Third Empty Canister
The third canister is the trickiest to obtain, as it requires at least two Combat Axes. You can purchase them from a Crafting Table, but some free ones can be found in specific locations. For instance, there's an Axe in the Pack-a-Punch chamber and another in the spawn area, with additional ones scattered around the map.
Once you have the Combat Axes, head into the Service Tunnel from the Mainframe Chamber. As you enter the tunnel, look to the left, and you'll spot an opening leading to a series of valves with leaking gas. Throw an Axe at the middle valve to redirect the gas, then hit the B-pipe valve to complete the flow.
Now, return to the Mainframe Chamber and locate a pod filled with flammable gas and cracked glass, present just to the left of the Crafting Table. Use either a Napalm ammo mod or any explosive equipment (Molotov, Thermo Grenade, and more) to break the glass. Once destroyed, the third canister will be available for collection.
Ray Gun Mark II-R upgrade guide (Yellow)
1) Collect four Plant Seeds
To upgrade the Wonder Weapon to Ray Gun Mark II-R, you first need to collect four Plant Seeds scattered across the map. These plants are distinguishable by their orange color and spawn randomly. Some common locations are:
- Garden Pond (near the starting area)
- Below the bridge
- Mansion entrance
- West Balcony
- Southwest Balcony
To collect the Plant Seeds, shoot the plants using one of these:
- Ray Gun Mark II
- Explosives
Do remember that shooting with normal weapons will not drop seeds.
2) Transform the Empty Canister into a Toxic Canister
- After collecting all four Plant Seeds, head to the Conservatory.
- Near the Ammo Cache, place the Empty Canister into a machine with a canister slot.
- Now, plant each seed in one of the four planters in the Conservatory.
- After planting each seed, you must defend it from attacking zombies. It is recommended to do this one by one.
- Repeat this process for all four seeds.
- Once completed, return to the canister slot, and you will now find a Toxic Canister instead of the Empty Canister.
3) Craft and Upgrade to Ray Gun Mark II-R
With the Toxic Canister in hand, make your way back to the Garden Pond (spawn area). Near this location, you’ll find a yellow workbench where you can upgrade your Ray Gun Mark II into the Ray Gun Mark II-R.
The Ritual Challenge (Library Liminal Portal activation)
- Go to the Library.
- On the east side, you will find a massive painting and a machine beside it.
- Interact with the machine to activate the painting (Liminal Portal).
- Multiple zombies will spawn. Use the Ray Gun Mark II-R (yellow variant) to eliminate them.
- As you eliminate zombies, their yellow souls will be absorbed into the Liminal Portal.
- You must fully charge the portal within a minute.
- Once charged, the painting will transform into a portal, granting access to a new room.
Collect three hidden items using Aether Shroud
Inside the newly opened room, you need to collect three hidden items, which can only be seen while using the Aether Shroud Field Upgrade:
- Audio Log
- Ledger
- Nuclear ID Card
Potential item location:
Audio Log
- Potential Location 1: Overlook area (above the Dino Skeleton Room), southeast corner, on a computer table.
- Potential Location 2: Library, in front of the portal, on a sofa above some machines.
Ledger
- Potential Location 1: East Foyer, on a study table (near the first potential Audio Log location).
- Potential Location 2: Study Chamber, opposite the Elemental Pop Perk-a-Cola machine, on another study table.
Nuclear ID Card
- Potential Location 1: East Foyer, inside a fireplace.
- Potential Location 2: Banquet Hall, beside the elevator.
Solve the glowing books puzzle
Once you have collected all three items, return to the Library and look for a bookshelf opposite the portal. Here, you will see three glowing books that must be activated in the correct sequence. If a book glows blue after interaction, continue with another one. If the previous book stops glowing, retry by interacting with the first one again, then test a different combination.
Once the correct sequence is completed, a hidden chamber will open, where you will find the required Ritual Item.
The Amalgam mini-boss fight
Enter the portal once again and place the Ritual Item on the pedestal to initiate a mini-boss fight. This will summon an Amalgam, along with normal zombies and parasites. The Amalgam can activate a shield that can only be damaged using the Ray Gun Mark II-R, so keep firing until the shield breaks. Once you defeat it, the Sentinel Artifact will be powered up. Collect it and proceed to the next ritual.
Ray Gun Mark II-P upgrade guide (Purple)
1) Collect two Reflective Discs
To begin the upgrade process, you must collect two Reflective Discs found inside fountains with stone lion engravings:
- First Reflective Disc: Located in the Southwest Balcony.
- Second Reflective Disc: Found outside the Conservatory chamber.
2) Obtain the Essence Bomb
Next, you need to find an Essence Bomb, which is hidden inside white boxes marked with the Project Janus symbol.
These boxes are scattered across the map, and you may need to shoot multiple ones before acquiring the bomb.
3) Open the blocked pathway in the Service Tunnel
Once you have the Essence Bomb, head to the Service Tunnel. To the left of the Armor Pack, there is a blocked pathway with rocks. Place the bomb there, and once it explodes, the path will open.
4) Solve the light reflection puzzle
Proceed down the path, and you will find another machine with a canister slot. Place the Empty Canister into it, which will cause a ray of light to appear. Now, use the Reflective Discs to align the beam of light so that it hits a Doppelgast statue. To activate the statue, melee the crystal where the beam originates. This will turn the Doppleghast statue into a real enemy which you must eliminate.
After defeating the first Doppleghast, realign the Reflective Discs to direct the beam toward another statue and repeat the process. There are three Doppleghast statues in total, and once all are eliminated, the Empty Canister will transform into a Light Canister.
5) Upgrade to Ray Gun Mark II-P
With the Light Canister in hand, head to the Doctor’s Quarters, where you will find a yellow workbench. Use this to upgrade your Ray Gun Mark II to the P variant (Purple Ray Gun Mark II-P).
The Ritual Challenge (Banquet Hall Liminal Portal activation)
Activate the Banquet Hall Statue
- Head to the Banquet Hall (where the elevator is present).
- Find the massive statue and interact with it.
- Multiple zombies will spawn that must be eliminated using the Ray Gun Mark II-P.
- You must kill all the zombies within the time limit to activate the Liminal Portal.
Enter the New Chamber and Collect the Ritual Elixir
- Once the portal opens, head inside the new chamber.
- On the dining table, you will find a red liquid bottle (Ritual Elixir).
- Collect it and proceed to the next step.
Find and pour Ritual Elixir into three chalices
Now, you need to locate three Chalices scattered across the map and pour the Ritual Elixir into each. Each Chalice will spawn an Elder Disciple, which you must eliminate before moving to the next one.
Chalice locations:
- First Chalice: Bottlery area, on a small table.
- Second Chalice: Garden Pond, near the bridge, left of the GobbleGum machine, on a bench.
- Third Chalice: Dino skeleton room, opposite the skeleton, on a bench in the Overlook area.
Get the Ritual Item from the safe
- After defeating all three Elder Disciples, head back to the Banquet Hall.
- Near the elevator, you will find three sets of numbers on the wall (note them down).
- Now, go to the West Hallway, where the Death Perception Perk-a-Cola machine is located.
- Find the safe in this room.
- Interact with it and enter the six-digit code from the Banquet Hall.
- The safe will unlock, and inside, you will find the Ritual Item.
Elder Disciple (Kurontha) mini-boss fight
After collecting the Ritual Item, return to the portal chamber in the Banquet Hall and place it on the pedestal. This will initiate a mini-boss fight against the Elder Disciple, Kurontha.
Kurontha will activate a shield that can only be broken using the Ray Gun Mark II-P. While fighting, waves of zombies will continue to spawn. Once Kurontha is defeated, the Sentinel Artifact will be powered up.
Finally, collect the Sentinel Artifact and move on to the next ritual.
Ray Gun Mark II-W upgrade guide (Blue)
1) Activate the Canister Machine in Shem's Henge
To begin upgrading the Ray Gun Mark II-W, head to Shem's Henge, where the Speed Cola Perk-a-Cola Machine is located. Nearby, you’ll find a machine with a canister slot. Place the Empty Canister inside it, which will trigger the spawn of an Abomination. However, do not kill it yet, as its attacks are crucial for progressing further.
2) Activate the three small rocks
Make your way to the circular arena, where you’ll find three small rocks on the ground. Stand behind one of these rocks and wait for the Abomination to unleash its beam attack. The beam must hit the rock, which will cause it to glow a blue hue. Repeat this process for the remaining two rocks to fully activate them.
Once all three rocks are glowing, the next step involves baiting the Abomination’s charge attack. You need to position yourself in such a way that when the Abomination rushes toward you, it crashes into one of the glowing rocks.
Doing so will cause the rock to float, and this process must be repeated for the other two rocks as well. Once all three are floating, the Abomination will automatically die, marking the beginning of Phase 2 of the upgrade process.
3) Defend the Power Extractor
With the Abomination defeated, the floating stones will begin charging the Power Extractor, but they will also attract waves of Vermins that will attempt to destroy the device. You must defend the Power Extractor for approximately two minutes until the process is complete. Once successfully defended, the Empty Canister will transform into an Explosive Canister, which you can now collect.
4) Upgrade to Ray Gun Mark II-W
Take the Explosive Canister to the Supply Depot area, where the portal is located. Inside, you will find a yellow Crafting Machine. Use this station to build the Ray Gun Mark II-W (White Variant).
The Ritual Challenge (Distillery Liminal Portal activation)
Collect the Lantern
With the newly acquired Ray Gun Mark II-W, you can now activate the Distillery Liminal Portal Challenge. The first step requires finding a small lantern, which is located near the Double Tap Perk-a-Cola Machine inside the mansion. As you enter the first chamber, where the GobbleGum machine is located, search for a box near the mounted deer heads, as the lantern will be inside it.
Solve the lantern puzzle
Once you have the lantern, head to the Grand Foyer, where the dinosaur skeleton is displayed. On the west side of the room, you'll find a lantern placed in a slot. To its right is the empty slot where you can put the second lantern.
This will initiate a light-blinking puzzle, where you must carefully follow the blinking sequence by interacting with the lanterns in the correct order. The sequence must be completed three times to unlock a hidden door.
Activate the Liminal Portal
Inside this newly revealed area, you will find a painting along with an activation machine. Interact with it to start the next phase of the ritual, which requires eliminating zombies using the Ray Gun Mark II-W within a time limit. Once the challenge is completed, the Liminal Portal will activate, revealing a new chamber.
Find and collect the Bell
The Bell is located in the Study Room (where the Elemental Pop Perk-a-Cola Machine is). It has three potential spawn locations:
- Bottom shelf, to the left of the computer table.
- Shelf to the right of the wall weapon-buy station.
- In the small study chamber, opposite Elemental Pop, on the display bench near the television.
Use the Brain Rot ammo mod to retrieve the Ritual Item
After acquiring the Bell, proceed to the Overlook area, specifically to the Southeast corner, where you will find a bar counter. Place the Bell on the counter and use the weapon with the Brain Rot Ammo Mod.
Now, wait for zombies to approach and transform one of them by shooting it near the counter. Once a zombie has been turned, ring the Bell multiple times. This will cause the zombie to move behind the counter and retrieve the Ritual Item, which you can then collect.
The Mangler mini-boss fight
Take the Ritual Item to the Liminal Distillery Portal and place it on the pedestal, which will trigger the Mangler boss fight. Similar to previous encounters, the Mangler will activate a shield that can only be destroyed using the Ray Gun Mark II-W.
Focus on breaking the shield first before unloading your attacks on the boss. Throughout the fight, expect additional zombie spawns, so managing your space is crucial. Once the Mangler Kurontha is defeated, retrieve the Sentinel Artifact.
With all the necessary steps completed, you are now ready to initiate the final boss fight. Before proceeding, ensure that you are well-prepared with a Self-Revive, a Chopper Gunner, fully maxed-out weapons, and enough armor and perks to sustain you during the battle. Once fully equipped, head to the Mainframe Chamber, where S.A.M. is present. Place the Sentinel Artifact in the console, triggering a cutscene and revealing the final boss: the Z-Rex.
Z-Rex boss fight (four phases)
The Z-Rex’s weak point is its eyes, so focus your shots on them for maximum damage. The boss battle will take place in a large arena, allowing you to run and maintain distance. However, as it moves, it will leave behind toxic trails, which can cause damage if you step on them.
Upon successfully defeating the Z-Rex, a final cutscene will play, revealing a twist in the storyline that changes the course of events. Without giving away spoilers, this marks the end of the Shattered Veil main quest easter egg guide in Black Ops 6 Zombies.
