Still getting lost while trying to unlock the Rex Infernace Easter egg? Reaching the boss only to run out of resources? Wondering which steps you can safely rush and which ones require patience? The key is preparation, not reckless speed. Bring a long-range AR, LMG, or marksman rifle for reliable crowd control, then focus on unlocking Pack-a-Punch and collecting the purple flame early. From there, temple puzzles, Warden’s Blight pieces, miracle weapons, and purification become the backbone of the run. If you need extra resources during progression, buy Black Ops 7 Bot Lobbies or look for cheap CoD BO7 Bot Lobbies to strengthen your setup.
Get Pack-a-Punch Online ASAP
Your early-game priority should be activating Pack-a-Punch. Follow the house progression, answer the phone, place the world seed, then locate and destroy the two Dread Skulls.
Return to the furnace, light both braziers, and turn the crank to activate the machine. Once the Void Base generates the grappling hook, use it to pull the nearby purple orbs back toward Pack-a-Punch.
After the cooldown, turn the crank again to obtain the purple flame. This item becomes essential for the temple purification sequence later.
Value for You:
Best for beginners and Easter egg speedrunners; establishes the core setup early and prevents unnecessary backtracking later.
Clear the Temples in the Right Order
The Nixara Temple should be your first major target. Use an explosion or PhD Flopper to break through the upper wall and collect the Fracture of Nixara.
Place the crystal in the wall, return to Pack-a-Punch for the flame, and light the eye. Then use the grappling hook to adjust the crystal until its beam breaks through the doorway.
Inside the sanctuary, watch for the vine-sucking mechanic and continue the sequence until the health bar is full. You can only progress after the 8th turn, so don’t waste time trying to force it earlier.
Value for You:
Best for solo players and route planners; helps you avoid failed attempts and understand the exact progression requirement.
Varion Temple: Solve the Tablet Puzzle
Next comes the Varion Temple. Equip Death Perception to locate the four stone tablets, then arrange them in this order: water, plant, hand, fire.
Use the wheel to move the elements to the opposite side. Completing the puzzle eventually rewards you with a random perk and a pool of water.
That pool matters more than it looks. Several later purification steps require a “rain turn,” so completing this sequence efficiently can save you major delays later in the run.
Value for You:
Best for Easter egg grinders and co-op teams; unlocks an important resource that supports multiple later purification objectives.
Dravacar & Calferas: Speed Matters
At the Dravacar Temple, read the inscription riddles carefully before entering the solutions for the left, center, and right switches. There are four riddles, each with a fixed answer.
Get the combinations right and the sanctuary opens, setting you up for the miracle-weapon stage. For Calferas Temple, the challenge is much more frantic: shoot the boxes from four pressure plates before the timer expires.
Move quickly. If you fail, you can continue on the next turn, so don’t throw away the entire run by panicking.
Value for You:
Best for speedrunners and co-op players; reduces puzzle downtime and helps you maintain momentum through the middle of the Easter egg.
Turn 8 Is Your Warden’s Blight Window
When Turn 8 arrives, enter the forest and collect the three Warden’s Blight components: the central rock, the wooden house floor piece, and the piece near the corpse inside the cave.
Once you have all three, return to the Dravacar shrine to forge the miracle weapon. Upgrading it immediately is strongly recommended because it becomes essential for the later purification sequence and boss preparation.
If resources are slowing your progression, purchasing additional coins can help you strengthen your equipment and reduce pressure during the mid-to-late game.
Value for You:
Best for resource-conscious players and speedrunners; gets your miracle weapon online quickly and makes the later stages more manageable.
Purify All Four Temples Without Losing Control
After aligning the four temples, the purification phase begins. You’ll need to place offerings, ignite the correct flames, and guide marked zombies into Titan traps.
Then use your miracle weapon to control the beam and purple orb positions. This stage rewards precision more than raw aggression, so avoid rushing inputs and triggering unnecessary mistakes.
Keep your team organized in co-op. One player can manage enemies while another focuses on the objective.
Value for You:
Best for co-op teams and experienced solo players; makes the most complicated late-game sequence easier to manage and reduces failed attempts.
Rex Infernace Boss Fight: Play Smart, Not Fast
Before entering the Nexus Core, aim for at least a triple upgrade and Legendary rarity. Survival skills and area-of-effect equipment are also highly recommended.
During the boss fight, don’t immediately tunnel on the Warden. Destroy the surrounding gray-blue skeletons first to stun him, then concentrate your damage on his tail—the primary weak point.
At the same time, keep clearing Shadow Souls and Warden Stingers. Allowing these enemies to pile up can overwhelm even a well-prepared team.
Value for You:
Best for boss-fight beginners and solo players; provides a safer damage sequence that improves survival and reduces chaotic wipes.
Final Takeaway
The Rex Infernace Easter egg becomes far more manageable when you stop treating it like a race and start treating it like a controlled route. Unlock Pack-a-Punch early, secure the purple flame, complete the temples efficiently, collect Warden’s Blight on Turn 8, forge and upgrade your miracle weapon, then enter the Nexus Core fully prepared.
The boss itself isn’t the biggest obstacle. Poor preparation and rushed decisions are. Follow the route, manage your resources, and stay disciplined when the arena gets chaotic. With the right setup, Rex Infernace is a challenge you can absolutely conquer. CoD BO7 Bot Lobbies at MMOexp to level up faster and stay ahead.
