The Tomb, introduced in Black Ops 6 Zombies with Season 2, features a new main quest Easter Egg that continues the storyline. Following the events of Citadelle des Morts, Professor Kraft reveals crucial intel about the location of the Sentinel Artifact, hidden in a nearby excavation site. This site is the new map, and the mission revolves around locating and securing the Sentinel Artifact.
The main quest is no walk in the park. Players will face narrative-driven tasks without guidance instead of relying on in-game hints to solve complex puzzles and challenges. As a result, this Easter Egg quest is one of the most challenging to complete.
Don’t worry — this article will provide a detailed, step-by-step guide to help you complete The Tomb main Easter Egg quest in Black Ops 6 Zombies.
How to Complete the The Tomb Main Quest Easter Egg in Black Ops 6 Zombies
For the initial part of the mission, you'll receive guided information instructing you to Open the Doorway to Nowhere. Completing this task solo can be very challenging, so it is highly recommended to attempt it with a squad. You will spawn at a location called the Dig Site, and from there, follow the first guided objective.
Open the Doorway to Nowhere
This task requires you to open three doors and reach a specific marked location. First, progress through a few rounds to gather enough Essence, as each door will require Essence to unlock. Look for doors in the Dig Site with a red glowing circle in the middle. Approach the first door, which will cost 2,250 Essence to unlock. Once inside, proceed to find another similar door, requiring 2,500 Essence to unlock. Continue into the newly unlocked room, where you’ll encounter the third door, costing 2,750 Essence.
In this room, you’ll find a small table with the purple glowing crystal, which will be marked. Approach the table and press the interact button to place the Amulet you obtained in Citadelle des Morts.
A purple ray will appear, and the wall with a runic symbol will transform into a portal. Approach the portal and you’ll have the option to teleport.
After stepping through the portal, you will be transported to the Dark Aether Nexus, where you’ll find the Pack-a-Punch machine. From this point onward, there won’t be any guided information, so you’ll need to rely on in-game hints to proceed.
Craft the Staff of Ice Wonder Weapon
Your next task is to craft the Staff of Ice. Start by reaching Round 8, at which point a Shock Mimic will spawn. Eliminate it to obtain a quest item called the Monocle. Once you’ve collected it, your next task is to shoot all the Aether Lanterns scattered throughout the map.
Next, head to the Tombs area, where you’ll find the new Death Perception Perk-a-Cola machine. There, on the wall, you will see a large painting of a bull. If you've shot all the lanterns, the bull painting will display glowing Roman numerals. Shoot the numerals in the correct order, and once you've finished, the room will go into lockdown.
You’ll now face five waves of zombies, including Shock Mimics and Doppelghasts. Survive the waves, and upon completion, you’ll receive the second item: the Staff.
For the final item, repeat the process of shooting all the lanterns. This time, head to the Neolithic Catacombs, where you'll find a mural with Roman numerals on the wall near the crafting table. Shoot the numerals in sequence to trigger another lockdown, which you’ll need to survive.
After completing this task, you’ll receive the third item: the Head Piece.
Now that you have all three items, head to the large circle in the center of the Dark Aether Nexus area. Interact with the Ice Staff, defend the location, and you will be able to craft the Staff of Ice Wonder Weapon.
Upgrade the Staff of Ice Wonder Weapon
Now that you have the Staff of Ice, your next task is to upgrade it. The upgraded version will feature a green crystal at the other end, which can instantly revive fallen allies.
Step 1: Freezing the Aether Lanterns
Exit the Dark Aether Nexus and return to the main map. Previously, you shot the Aether Lanterns to trigger the Roman numeral puzzle. This time, instead of shooting them, you must use your Staff of Ice to freeze them.
However, you must freeze three lanterns within 10 seconds. To do this efficiently:
- Before starting, scout a route with the three closest lanterns.
- Once ready, quickly freeze them in succession to complete the task within the time limit.
If done successfully, Archibald will speak, confirming that you have completed this step.
Step 2: Shooting the floating rocks
Return to the Dark Aether Nexus, where you'll find large floating rocks. Among them, three rocks will have glowing purple symbols. These symbols are easy to distinguish due to their bright symbol color.
- Use your Staff of Ice to shoot each of the three marked rocks.
- After being hit, each rock will descend.
- Important: Take screenshots or write down the symbols for later reference
Next, locate the four portal doors that connect the Nexus to the outer world. One of these portals will now be closed.
- Identify which portal is closed.
- Use any of the remaining portals to return to the outer world.
- Find the room where the opposite end of the closed portal is located.
- At the door, you will see eight symbols.
- Using your Staff of Ice, shoot only the three symbols that match the ones you noted earlier.
Step 3: Collecting souls for the upgrade
If you have correctly matched the symbols, the portal will reactivate. Enter it, and you’ll be teleported to the top of a floating rock, where you’ll find a glowing purple orb.
- Interact with the orb to initiate a soul collection sequence.
- The orb will start moving—follow it and eliminate zombies nearby.
- The orb will automatically absorb zombie souls, but you must stay close to it.
- If you move too far away or don’t collect enough souls, you will fail and need to restart this step.
As the orb moves, it will eventually reach its final destination, the large stone structure in the center of the Dark Aether Nexus.
- Equip your Staff of Ice and interact with the orb at the stone structure.
- This will complete the upgrade, granting you a more powerful version of the Wonder Weapon.
Upgraded Staff of Ice abilities
Once upgraded, the Staff of Ice gains two powerful abilities:
- Ice Storm – Freezes multiple enemies at once.
- Sekhmet's Vigor – Shoots a healing orb that can revive downed allies.
Activating the statues
In this final stage, you must activate four statues to form a bridge leading to the final boss encounter.
Understanding the Statues
There are four statues in the Dark Aether Nexus, each linked to a corresponding statue in the outer world:
- Vermin State: Dig Site, the location where you spawn
- Parasite Statue: Shrine of the Hierophants, the location where the Stamin-up Perk-a-Cola is present
- Doppleghast Statue: Ossuary, the location where the Speed Cola Perk-a-Cola is present
- Amalgam statue: Deep Excavation, the location where the Quick Revive Perk-a-Cola is present
Once familiar with these locations, you can proceed with activating each statue.
1. Activate the Vermin Statue
- In the Dark Aether Nexus, approach the Vermin Statue and shoot its small crystal using Sekhmet’s Vigor (the green crystal on the Staff of Ice).
- Travel to the Dig Site in the outer world and find the Vermin Statue located west of the Rampage Inducer.
- Stand inside the circle that appears and eliminate Vermins. The energy from the eliminated enemies will transfer to the statue.
- Once the statue has absorbed enough energy, interact with it to absorb the energy into your body.
- Quickly return to the Dark Aether Nexus and transfer the energy to the Vermin Statue there.
Note: Avoid taking damage while carrying the energy—after three hits, you’ll lose it and must restart the process.
2. Activate the Parasite Statue
- Interact with the Parasite Statue in the Dark Aether Nexus.
- Travel to the Shrine of the Hierophants (Stamin-Up Perk-a-Cola location) in the outer world.
- Stand in the activation circle and eliminate Parasites to collect energy.
- Absorb the energy from the statue and return to the Dark Aether Nexus without taking too many hits.
- Transfer the energy to activate the Parasite Statue.
3. Activate the Doppelghast Statue
- Interact with the Doppelghast Statue in the Dark Aether Nexus.
- Travel to the Ossuary (Speed Cola location) in the outer world.
- Stand inside the circle and eliminate Doppelghasts. However, this phase is more challenging:
- Lasers will be emitted from the statue, so you must dodge them while fighting.
- Once you have absorbed enough energy, return to the Dark Aether Nexus and transfer it to the Doppelghast Statue.
4. Activate the Amalgam Statue
- Interact with the Amalgam Statue in the Dark Aether Nexus.
- Travel to Deep Excavation (Quick Revive location) in the outer world.
- A Red Amalgam will spawn instead of a normal one: this enemy is stronger, has a shield, and requires more damage to defeat.
- Defeat the Red Amalgam, absorb the energy, and return to the Dark Aether Nexus.
- Transfer the energy to activate the final statue.
Initiating the Final Boss fight
Once all four statues are activated, a massive purple laser will shoot into a gateway.
- Head toward the gateway, where you will find a pedestal.
- Interact with the pedestal to open the gateway, forming a bridge to a nearby location.
- Cross the bridge to find the Sentinel Artifact.
- Interact with the artifact—this will trigger the final boss fight.
The Sentinel Artifact itself is the final boss of The Tomb Easter Egg. Defeat it and you will be able to collect it.
Once you’ve secured the Sentinel Artifact, the main quest of The Tomb will be completed.
