Astra Malorum Easter Egg

Ultimate Astra Malorum Easter Egg Guide (March 2026)

Table Of Contents

I’ve spent countless hours exploring the skull-shaped rock of Astra Malorum, and let me tell you – this Black Ops 7 Zombies map is an absolute masterpiece of design and challenge. As someone who’s tackled every major Zombies easter egg since the original World at War, I can confidently say that Astra Malorum stands out as one of the most intricate and rewarding experiences Treyarch has ever created. The journey from turning on the power to facing the final boss Caltheris is filled with clever puzzles, intense combat, and that perfect blend of frustration and triumph that makes Zombies mode so addictive.

What Is Astra Malorum?

Astra Malorum, which translates to “Stars of Evil” in Latin, represents Treyarch’s boldest creative vision yet in the Black Ops 7 Zombies universe. This interstellar adventure transports our favorite crew to a mysterious Dark Aether planet after Ol’ Tessie’s unexpected journey through space. The map seamlessly blends the classic Zombies formula with science fiction elements, creating an experience that feels both familiar and refreshingly new.

What makes Astra Malorum special is its multi-layered design. You’re not just running around shooting zombies – you’re exploring an observatory, museum, and even making your way to Mars itself. The easter egg quest weaves through all these areas, requiring you to solve complex puzzles, collect unique items, and ultimately face off against one of the most challenging bosses in Zombies history. The attention to detail is incredible, with each area telling its own story while contributing to the larger narrative.

Why I Enjoy Playing Astra Malorum?

I’ll be honest – my first few attempts at the Astra Malorum easter egg left me frustrated and ready to rage quit. But there’s something about this map that kept pulling me back. Maybe it’s the satisfaction of finally solving that tricky planet puzzle, or the adrenaline rush of successfully defending the brain canister during lockdown sequences. Or perhaps it’s the sheer joy of watching all your hard work pay off when you finally activate the portal to Mars.

What really sets Astra Malorum apart for me is how it rewards both individual skill and teamwork. Playing solo requires precision and patience, while co-op adds that extra layer of coordination and communication that makes Zombies so special. I’ve had some of my most memorable gaming moments here – from barely surviving a lockdown with just seconds left on the timer to the epic final boss fight that had my heart pounding like crazy.

The map’s atmosphere is another huge plus. The combination of cosmic horror and scientific elements creates this unique vibe that’s both unsettling and fascinating. Every time I play, I discover new details in the environment that add to the lore and make the experience richer.

How to Complete the Astra Malorum Main Easter Egg?

Alright, let’s dive into the meat of this guide. I’ve broken down the entire easter egg quest into manageable steps, complete with the tips and tricks I’ve learned through trial and error. Follow these carefully, and you’ll be well on your way to completing one of Black Ops 7’s most challenging easter eggs.

Step 1: Power Up and Activate Pack-A-Punch

First things first – you need to get the power running and access Pack-A-Punch. This is your foundation for everything else, so take your time and get it right.

  1. Purchase the necessary doors to reach the Observatory Dome
  2. Collect Harmonic Components from The Luminarium and Machina Astralis
  3. Return to the Observatory Dome and interact with the Harmonic Oculus (the piano)
  4. Survive the lockdown sequence – this is your first real test, so be prepared
  5. Enjoy your new Pack-A-Punch access and powered-up map

Pro tip: During the lockdown, focus on survival first. Use the environment to your advantage and don’t get greedy with kills. The lockdown will end eventually, so prioritize staying alive over racking up points.

Step 2: Obtain the LGM-1 Wonder Weapon

The LGM-1 is essential for the later stages of the easter egg, so you’ll want to get this as soon as possible. Here’s how:

  1. Spawn OSCAR by surviving enough rounds
  2. Shoot his UFO projectiles with a Pack-A-Punched weapon to get the Damaged Drone
  3. Purchase the Cryo Freeze Ammo Mod from an Arsenal machine
  4. Find and shoot three Dark Aether Crystals around the map to collect Absolute Zero Fragments
  5. Locate the flickering lamppost (location varies) and shoot it for Aberrant Wiring
  6. Shoot Ol’ Tessie’s bonnet to obtain the Car Battery
  7. Trap OSCAR three times using different map traps:
    • Electro-Volt Projector in The Luminarium
    • Rocket Ignition in Museum Infinitum
    • Planetary Telescope in Observatory Dome

After defeating OSCAR three times, he’ll drop the LGM-1 Wonder Weapon. Trust me, this weapon is worth the effort – it’s incredibly powerful and essential for the final stages.

Step 3: Solve Thurston’s Planets Puzzle

This is where things get really interesting. You’ll need to pay close attention to audio cues and have your subtitles ready.

  1. Follow OSCAR stealthily – don’t let him detect you
  2. Listen for Dr. Thurston’s audio logs – he’ll name three planets
  3. Note the three planets mentioned (e.g., Venus, Earth, Saturn)
  4. Convert planets to numbers based on distance from the sun:
    • Mercury = 1, Venus = 2, Earth = 3, Mars = 4
    • Jupiter = 5, Saturn = 6, Uranus = 7, Neptune = 8
  5. Enter the code at the terminal in the Observatory Dome
  6. Collect the Cryo Chamber Key from the raised platform

This step requires patience. If OSCAR detects you, you’ll need to wait for him to respawn and try again. Take your time and follow him carefully.

Step 4: Acquire Dr. Thurston’s Brain

Yes, you read that right – you need to collect a brain. This is Zombies mode, after all!

  1. Grab the Rock Saw from the display case in Museum Infinitum
  2. Head to Machina Astralis and use the Cryo Chamber Key on the cryo pod
  3. Use the Rock Saw to extract Dr. Thurston’s brain
  4. Take the brain to The Luminarium and interact with the brain canister twice
  5. Defend during the 60-second lockdown – this can get intense!
  6. Return the brain to Machina Astralis and place it in the Perfusion Machine

The brain canister lockdown is one of the most challenging sequences. I recommend setting up traps beforehand and having a good loadout ready. The zombies come fast and furious!

Step 5: Solve the Books and Statues Puzzle

This puzzle tests your memory and attention to detail. Here’s how to tackle it:

  1. Note the five book titles that appear on the monitor next to the brain machine
  2. Head to the Archive of Orbis and locate these books on the shelves
  3. Count how many books from your list are on each wall
  4. Interact with the busts at the end of each wall (once for each book)
  5. Climb the ladder that appears and collect the Planet Neptune item

This step is timed, so I suggest quickly counting the books on each wall first, then going back to interact with the busts in sequence. Communication is key if you’re playing co-op!

Step 6: Align the Planets and Activate the Portal

You’re getting close to the end! This step involves some planetary alignment and portal activation.

  1. Place Planet Neptune in the empty slot in the Machina Astralis planetarium
  2. Find three pieces of paper with planet and direction clues:
    • Machina Astralis main room (south wall)
    • Archive of Orbis center (desk with notes)
    • The Luminarium (northwest coffee table)
  3. Shoot the planets in the directions specified by the papers
  4. Interact with the brain machine to start the final lockdown
  5. Defend the portal from OSCAR’s UFO projectiles for 2 minutes
  6. Get ready for Mars – you’ll be automatically transported there

The portal defense is crucial. Focus on destroying the UFO projectiles first, then handle the zombies. If too many projectiles hit the portal, you’ll fail the sequence and have to start over.

Step 7: Mars Sequence and Final Boss Setup

Welcome to Mars! This final sequence is both beautiful and challenging.

  1. Pick up the brain canister in the central area
  2. Place it in the machine near where you spawned
  3. Listen for the ethereal chime that signals the Artifact’s presence
  4. Look through the southeast window and shoot the four pylons in order:
    • Back right → Back left → Front right → Front left
  5. Shoot the metallic obelisk above the spawn portal repeatedly
  6. Grab the Ascendant Eye when it flies down during low gravity
  7. Place the Ascendant Eye in the golden pillar in the south corner
  8. Return to Observatory Dome and note the four symbols on the device
  9. Back to Mars – shoot the pillar tops with LGM-1, then interact in symbol order
  10. Interact with the brain to summon the final boss, Caltheris

The Mars sequence is my favorite part of the easter egg. The low gravity mechanics add a unique twist, and the visual design is absolutely stunning. Take a moment to appreciate it before the boss fight!
