CoD Black Ops 7 Zombies Easter Egg: Early Setup and Temple Puzzles
The CoD Black Ops 7 Zombies Easter Egg can be completed in Solo or Co-op, but the full quest is lengthy. A long-range Assault Rifle, LMG, or Marksman Rifle is recommended, especially for later boss phases.
Start by completing the opening objective. Travel through the house, answer the phone, reach the main map, place the World Seed, and follow the two Dread Skulls. Shoot them as they travel toward the main chambers, then bring their flames back to the Forge.
Repeat the process twice to light both braziers, then rotate the crank wheels to activate Pack-a-Punch.
Void Pedestals will then appear around the map. Use a Grapple Hook to pull a nearby purple Orb toward Pack-a-Punch. Once the Orb is positioned correctly, rotate the crank again to generate Astral Flame, which becomes essential for later stages.
The Four Temple Objectives
The REX INFERNUS EASTER EGG requires players to complete four major Temple puzzles: Nixara, Varion, Dravacar, and Calferis.
Nixara: Collect the Fracture of Nixara, manipulate the Crystal Beam with the Grapple Hook, and unlock the Inner Sanctum.
Varion: Collect four elemental blocks-Water, Plant, Hand, and Fire-and solve the movement puzzle.
Dravacar: Read the randomly generated riddle and activate the three switches using the correct combination.
Calferis: Complete four timed Pressure Plate shooting challenges to unlock the next part of the quest.
Pro Tip: Try to complete the four Temple setup puzzles before Round 8. Getting these objectives done early makes the later Wonder Weapon and cleansing stages much easier.
Warden's Blight, Corruption Items, and Temple Cleansing
After opening the Nixara Inner Sanctum, players can enter the secret forest area. Here, three dead bodies must be investigated to obtain the three components required for Warden's Blight.
Return to Dravacar Sanctuary and use the Anvil to craft the Wonder Weapon. If playing Co-op, additional players can obtain Warden's Blight from the Mystery Box afterward.
Once the weapon is crafted, Pack-a-Punch it as soon as possible. You must also track four symbols that gradually appear on the front of the house. Record their spawn order because they must later be shot from oldest to newest during an Exfil Round.
Meanwhile, collect the four Corruption Items:
Shimmering Thread: Use the Void Claw to pull purple Orbs and interact with them until the item drops.
Blacksmith's Hammer: Enter Dravacar's Inner Sanctum with Shatter Blast Ammo Mod and destroy the correct Shield.
Ancient Scroll: Enter the forest with Shadow Rift Ammo Mod and trigger it against a large group of Zombies.
Woven Sash: Activate the water pool in Varion Sanctuary to guarantee rain on the following round, then search the possible out-of-bounds locations.
Once all four items are collected, use the Nexus Forge mechanisms to align the three rings with each Temple.
Temple Cleansing Checklist
| Temple | Required Item | Main Mechanics |
| Varion | Woven Sash | Cauldron, Laser, Shadow Souls |
| Dravacar | Blacksmith’s Hammer | Pressure Plate, Laser, Titan Trap |
| Calferis | Corruption Item | Pressure Plate, Shadow Souls |
| Nixara | Ancient Scroll | Laser Alignment, Shadow Souls |
Each Temple follows a similar structure. Place the required item in the Cauldron, activate it with Astral Flame, lead the marked Zombie to the correct Titan Trap, and then complete the Temple's Pressure Plate and Laser puzzle.
After enough Zombies are killed, the Temple's head appears and summons four Shadow Souls. Destroy all four, shoot the Temple head, and then complete the final Orb-and-Flame sequence.
Rain is particularly important because several final cleansing actions require a rain round. Activating the Varion Sanctuary pool one round beforehand can therefore save significant time.
Rex Infernus Final Boss Fight
Once all four Temples have been cleansed, head beneath Pack-a-Punch into the Nexus Core. Each player must stand on a glowing circle to enter the final encounter.
Before entering, prepare Triple Pack-a-Punch weapons, Legendary gear, Warden's Blight, a strong long-range firearm, and useful Field Upgrades such as Ether Shroud or Frenzied Guard. Kazimir Grenades and powerful GobbleGums can also provide valuable breathing room.
The final encounter contains four major damage phases. Warden is surrounded by gray-blue Skulls that must be destroyed first. Once the Skulls disappear, the boss becomes vulnerable and you should focus fire on its Scorpion Tail.
Warden moves extremely quickly and can deal devastating damage. Keep moving clockwise or counterclockwise instead of standing still. Shadow Souls will appear during immune phases, while Warden Stingers can create a dangerous late-fight wipe condition if left alive.
Warden's Blight is especially useful for clearing these threats quickly while also dealing strong damage to the boss. After destroying the Skulls, switch to your long-range weapon and unload on the Scorpion Tail.
Boss Tip: Prioritize mobility, armor management, Skull destruction, and Warden Stingers. Frenzied Guard can be especially useful when armor becomes scarce.
Conclusion
The CoD Black Ops 7 Zombies Easter Egg is a long multi-stage quest, but the route becomes much more manageable when the four Temple puzzles, Warden's Blight, Corruption Items, and cleansing phases are completed in the correct order. With strong preparation and disciplined movement, the Rex Infernus boss fight becomes far more manageable. For players who want to speed up their setup, Black Ops 7 Bot Lobbies can help with preparation.
TL;DR
The REX INFERNUS EASTER EGG requires four Temple puzzles, Warden's Blight, four Corruption Items, four cleansing sequences, and the final Warden encounter. Complete as many early objectives as possible before Round 8 and save strong gear for the final fight.
Which part of the Rex Infernus Easter Egg gives you the most trouble-the Temple puzzles, item hunting, or the final Warden boss fight?
