Call of Duty: Black Ops 7 has brought one of the most ambitious Zombies maps to date with Astra Malorum, taking players on a thrilling interstellar journey. Set in a Dark Aether-infused observatory, this map challenges players to face sci-fi robots, navigate complex puzzles, and defeat the formidable boss Caltheris. If you're looking for a comprehensive step-by-step guide to the Astra Malorum Easter Egg (EE), you've come to the right place.

Step 1: Turn on Power and Activate Pack-a-Punch

The first step in Astra Malorum is to turn on the Power and activate Pack-a-Punch. Purchase the doors leading to the Observatory Dome, then locate the Harmonic Component items scattered across The Luminarium and Machina Astralis.

Once collected, return to the Observatory Dome and interact with the Harmonic Oculus (a piano). This triggers a lockdown sequence, which, upon completion, powers up the map and grants Pack-a-Punch access for your weapons crucial step for surviving high rounds and completing the Easter Egg.

Step 2: Obtain the LGM-1 Wonder Weapon

The LGM-1 Wonder Weapon is central to the Astra Malorum EE. To acquire it, follow these steps:

1. Damaged Drone - Shoot a drone deployed by O.S.C.A.R. to get the drone part.

2. Absolute Zero Fragments - Shoot Dark Aether Crystals with a gun equipped with the Cryo Freeze Ammo Mod. Collect three fragments.

3. Car Battery - Use Ol' Tessie at the Crash Site to obtain the battery.

4. Aberrant Wiring - Shoot a flickering lamp post that appears randomly on the map.

5. Electro-Volt Projector Trap - In The Luminarium, overcharge O.S.C.A.R.'s battery by destroying his drones.

6. Rocket Ignition Trap - In Museum Infinitum, lure O.S.C.A.R. behind the rocket thruster and activate the trap.

7. Observatory Dome Trap - Align the telescope with the Sun by shooting five burst gas pipes. Trigger the laser trap opposite Pack-a-Punch to damage O.S.C.A.R.

Completing these steps successfully will cause O.S.C.A.R. to drop the LGM-1, allowing you to continue the Easter Egg quest.

Step 3: Solve Thurston's Planets Puzzle

After acquiring the LGM-1, locate O.S.C.A.R. and follow him without alerting him to hear audio logs of Dr. Thurston. Take note of the planets he names and their numbered positions from closest to furthest from the Sun:

·Mercury - 1

·Venus - 2

·Earth - 3

·Mars - 4

·Jupiter - 5

·Saturn - 6

·Uranus - 7

·Neptune - 8

Input the three-digit code derived from the planets at the northwest code machine in the Observatory Dome to spawn a platform and acquire the Cryo Chamber Key.

Step 4: Acquire Dr. Thurston's Brain

Head to Machina Astralis and use the Cryo Chamber Key to open the cryo pod, revealing Dr. Thurston's corpse. Grab the Rock Saw from Museum Infinitum, return to Machina Astralis, and saw open the skull to obtain his brain.

Tip: Practicing this step in Call of Duty Black Ops 7 Bot Lobbies allows you to perfect timing and lockdown defense strategies without risking real multiplayer mistakes.

Step 5: Solve the Books and Statues Puzzle

At Machina Astralis, the monitor displays five book titles. Memorize them and head to the Archive of Orbis. Interact with the bookshelves and associated statues to match the correct number of books to the statue interactions. Complete this in roughly 15 seconds to reveal a trap door containing the Planet Neptune item.

Step 6: Align the Planets in Machina Astralis

Place Planet Neptune in the planetarium slot. Collect three papers showing planets and directions, then return to Machina Astralis. Shoot the planets in the correct directions to start a 2-minute lockdown defending the portal from O.S.C.A.R.'s drones. Survive to be teleported to Mars.

Step 7: Activate Pylons and Grab the Ascendant Eye on Mars

Place the brain at an altar on Mars. Interact with four pylons in this order: back right → back left → front right → front left. Shoot the orb above the temple to spawn the Ascendant Eye, freeze it by shooting repeatedly, and grab it when it's low. Place the Ascendant Eye in a golden pillar in the south corner.

Step 8: Find the Symbol Sequence and Shoot the Mars Pillars

Back in Astra Malorum, interact with the Observatory Core device to view a symbol sequence. Return to Mars and shoot the five corresponding pillars with the LGM-1. This primes the pillars for the final boss fight.

Step 9: Harmonize the Pillars and Summon the Boss

Interact with the pillars in the correct sequence quickly. Successful interaction glows the pillars blue and triggers the summoning of Caltheris, the Easter Egg boss.

Step 10: Defeat Caltheris, the Boss Fight of Astra Malorum

The boss fight has four phases:

1. Caltheris in the sky - Avoid lasers and feed zombie souls into generators.

2. Rock Monster - Attack glowing blue weak spots while dodging charges.

3. Caltheris Ascendant - Similar to Phase 2 but larger and throwing rocks.

4. Caltheris the Needle - Giant rock monster with gas clouds; focus weak points while keeping distance.

Defeat all phases to complete the Astra Malorum Easter Egg and enjoy the cutscene. Completion also unlocks Cursed Relics for continued gameplay.
