Unlocking the Agarthan Device Relic in Black Ops 7 Zombies is one of the most rewarding challenges in the game. It is not just about survival or high rounds. This relic is tied to a deeper Easter egg quest that tests your understanding of the map, your teamwork, and your ability to stay calm under pressure. If you want to claim this powerful item, you will need to follow a series of precise steps and complete several hidden objectives.

Before you begin the quest, it is important to know what you are working toward. The Agarthan Device Relic is a special artifact that grants unique abilities once unlocked. Players report boosts to survivability, improved damage output, and access to hidden mechanics that are not available during normal gameplay.
However, unlocking it is not simple. You must progress through a multi-step Easter egg that involves exploration, puzzle solving, and combat efficiency.
Step 1: Activate Power And Access Key Areas
Your first objective is to fully power the map. This step is essential because most of the quest elements are locked behind powered doors and systems.
Focus on:
- Turning on all power switches across the map
- Opening critical pathways
- Unlocking the Pack-a-Punch machine
Once power is active, you will notice new interactable objects appearing. These are your first clues that the Easter egg has begun.
Step 2: Locate The Ancient Symbols
After activating power, your next task is to find a set of hidden symbols scattered around the map. These symbols are usually located in hard-to-spot areas such as walls, underground chambers, or near ritual sites.
Pay close attention to your surroundings. The symbols often glow faintly or emit a subtle sound cue.
To complete this step:
- Find all required symbols
- Interact with them in the correct order
- Listen for confirmation audio after each interaction
Getting the order wrong may reset your progress, so take your time and observe carefully.
Step 3: Charge The Relic Fragments
Once the symbols are activated, relic fragments will spawn across the map. These fragments must be charged using zombie souls.
This is where combat skill becomes critical.
To charge fragments effectively:
- Lead zombies toward the fragment locations
- Eliminate them within the designated area
- Avoid moving too far away, as progress may stop
Each fragment requires a specific number of kills. When fully charged, it will glow brightly and disappear, signaling completion.
Step 4: Complete The Ritual Trials
After charging all fragments, a set of ritual trials will begin. These trials are designed to test different aspects of your gameplay.
Common trial types include:
- Surviving waves in a confined space
- Eliminating enemies using specific weapons
- Protecting an objective from incoming zombies
These trials increase in difficulty, so preparation is key. Make sure you have upgraded weapons, perks, and enough resources before starting.
Failing a trial may force you to restart the sequence, so coordination and awareness are crucial.
Step 5: Solve The Central Puzzle
With the trials complete, you will unlock access to the central puzzle room. This is one of the most complex parts of the quest.
The puzzle typically involves:
- Rotating symbols or mechanisms
- Matching patterns based on earlier clues
- Timing your interactions correctly
There is no room for random guessing here. The puzzle is designed to reward players who paid attention earlier in the quest.
Take a moment to recall symbol patterns and sequences you encountered before. These are often the key to solving the puzzle quickly.
Step 6: Defeat The Guardian Boss
Once the puzzle is solved, the final phase begins. A powerful boss known as the Guardian will spawn.
This fight is intense and requires full focus.
To defeat the Guardian:
- Target weak points when they are exposed
- Keep moving to avoid heavy attacks
- Use high-damage weapons and special abilities
Teamwork plays a major role here. If you are playing solo, you will need strong positioning and efficient resource management.
Defeating the boss will trigger the final reward sequence.
Claiming The Agarthan Device Relic
After the Guardian is defeated, the Agarthan Device Relic will appear at the center of the arena. Interact with it to complete the quest and unlock its benefits.
At this point, you will gain access to its abilities for the remainder of the match. Some players also report that unlocking the relic once may carry progression benefits into future runs.
Tips For Success
To make the process smoother, keep these tips in mind:
- Always stay aware of your surroundings
- Upgrade your weapons early
- Save powerful equipment for later stages
- Communicate clearly if playing in a team
- Do not rush puzzle steps
Patience and preparation matter more than speed.
