In Cursed Mode of CoD Bo7 Zombies, a glitch exists that allows a single player to obtain Agarthan Device Relic and gain unlimited experience.
This glitch in CoD Bo7 Zombies doesn't rely on multiplayer cooperation, but requires the player to not save and exit during a single run; otherwise, all progress will be reset.
The entire process is divided into four main parts: preparation, activation, positioning, and phase response. Each part requires precise resource preparation and timing.
Preparation
Before entering the glitch, the player must complete the construction of three basic pieces of equipment and collect three key items. These steps are indispensable and must be completed consecutively within the same run.
Basic Equipment
First, Wonder Weapon needs to be built, which is the foundation for subsequent high-wave output. Simultaneously, acquire ARC-XD and use it to detonate near the bottom of the building at Pack-a-Punch location. In the destroyed area, enter the cell and pick up Walkie-Talkie.
Next, enter Tyr's Head on the map and use the exit tubes. After passing through the tubes, the player will be randomly teleported to one of the special rooms.
The first target room is the bedroom, where you can find Mr. Peeks under the bed. The second special room contains a table surrounded by mannequins of fallen characters from Black Ops Cold War. On a shelf in this room, you can find a Soldier Helmet. You have collected Walkie-Talkie, the doll, and Soldier Helmet.
Tips
During the collection process, you can use two techniques to quickly acquire resources. When double points are available, use the ultra Gobblegums from your inventory to crush unwanted super-quality bubblegum; each piece will instantly grant 10,000 points.
Additionally, equip Mule Kick Augment on Mule Kick. When switching to a new weapon, there's a chance it will automatically gain the same Pack-a-Punch tier as the current weapon, resulting in a triple Pack-a-Punch effect. These resources are used for subsequent gnome Easter Egg consumption.
Trial Entrance
After completing the item collection, you need to go to Core Foundry area to perform a crucial step in the activation ritual.
Triggering a Flashback
Equip the melee Macchiato and perform melee attacks on a red and white barrel inside the Core Foundry. When you hit the barrel, a piece of metal pops out and triggers a flashback. Note that saving and exiting the game during this process will invalidate the flashback, reset the barrel's interaction state, and cause collected items to disappear.
Therefore, all actions must be performed consecutively within the same game session.
After the flashback ends, interact with the throne in the scene and place the previously collected Mr. Peeks, Walkie-Talkie, and Soldier Helmet on the throne in that order. Once placed, a laugh will be triggered, indicating that Trial entrance to Dry Dock has been generated.
Preparation Before Teleportation
Before entering Trial entrance, players must complete "No Me Sir Easter Egg." This Easter Egg must be completed before activating Trial entrance. Using Aftertaste Gobblegum is highly recommended.
Use this once before entering Trial entrance. This step ensures that you won't lose all skills and upgrades upon death during the subsequent high-pressure phase.
Catching the Pit
Trial entrance will take players into Dry Dock. The core of the glitch is located next to a pipe here.
Location
An invisible collision volume barrier exists around the pipe. Players need to slowly move outwards from the edge of the pipe until they find a specific spot. At this spot, zombies will perform an attack animation, but the attack will not hit the player character.
By repeatedly fine-tuning the backward distance, damage from regular zombies can be completely avoided. For the enemies in the first and second phases, this blocking position is sufficient to safely pass through. Players can use melee attacks to clear approaching zombies during this time.
Special Zombies
When special zombies appear, Toxic Growth skill needs to be used. Placing this skill in front of the pipe path will significantly slow down the special zombies, creating enough opportunities for players to attack and kill them.
The third phase begins with HVT-type heavy units. The economic resources accumulated through crushing Gobblegums and Mule Kicks will be needed.
Phase Progression
Upon entering the third phase, the gnome Easter Egg's economic cycle mechanism needs to be activated. Before this, Gnom statue in Dry Dock must be found and interacted with to activate Easter Egg.
Once activated, it can be used twice per round, each time consuming 6000 points. The method is: crouch and use PhD Floppers Augment to bounce off specific walls. By repeatedly consuming points to trigger the gnome Easter Egg, powerful buffs or instant kill effects can be continuously obtained.
Phases four and five are relatively simple; just return to the pipe checkpoint, clear out the regular zombies, and complete the kill objectives for each phase. Phase six introduces more HVT units, at which point using the acquired War Machine is highly recommended.
Combined with the continuous output provided by the gnome Easter Egg, War Machine can effectively kill elite units in clusters. After completing all six phases, the player officially obtains Agarthan Device Relic.
Key Points
After completing all phases, you can safely save and exit the game. To obtain Music Box Relic, you need to continue to round 60. There is a very high chance of failure in this process: at the top of the robot head, you need to purchase a sniper and accurately shoot the zombies below.
If this step fails, all subsequent actions will be impossible.
Additionally, activating Trial entrance, which involves spawning two special rooms from Tyr's Head via tubes, can take a significant number of rounds.
This will result in zombies reaching round 60 strength by the time you enter Trial entrance. Therefore, you must ensure all equipment is upgraded to the highest level and you have sufficient resources before entering Trial entrance.
The core of this exploit lies in using the hidden collision boxes in the dry dock pipes to achieve a damage-free blocking position, and strictly following the item collection and ritual activation process within a single run. Completing all six stages will reliably grant you Agarthan Device Relic.
