How to Get the LGM-1 Wonder Weapon in Black Ops 7 Zombies (Astra Malorum Guide)

The LGM-1 is Astra Malorum’s signature Wonder Weapon, and if you’re diving into this interstellar zombies map, you’ll definitely want to add this alien gadget to your arsenal. Like other map-specific Wonder Weapons in Black Ops 7 Zombies, there’s a free quest you can complete to earn it—no mystery box luck required.

In this guide, I’ll walk you through every step needed to unlock the LGM-1 Wonder Weapon, including all four contraption parts and the three traps you’ll need to take down O.S.C.A.R. Plus, I’ll share some insights on whether this weapon is actually worth the effort. Let’s get started!

Prerequisites: Power and Pack-a-Punch

Before you can begin hunting for the LGM-1 Wonder Weapon, you’ll need to complete two essential tasks:

• Turn on the power across the Astra Malorum map
• Activate Pack-a-Punch in the Observatory Dome

Once you’ve got these basics covered, you’re ready to start collecting the four contraption parts. The good news? You can grab these parts in any order you want, so feel free to tackle them however makes sense for your playthrough.

Step 1: Collect All 4 Contraption Parts for the LGM-1

Contraption Part #1 – Damaged Drone (O.S.C.A.R.’s Drone)

Once power is activated, O.S.C.A.R. will spawn as an Elite Enemy somewhere on the map. Here’s what you need to do:

• Open your Tac Map and locate O.S.C.A.R.
• Find him and destroy one of his flying drones
• The drones are vulnerable to Brain Rot ammo, but any decent weapon works in early rounds
• Pick up the Damaged Drone part when it drops
• Get away from O.S.C.A.R. quickly—you’re not ready to fight him yet

Pro tip: Don’t engage O.S.C.A.R. himself at this point. You just want his drone, then you’re out. Save your ammo and armor for later steps. If you’re looking for more ways to handle tough enemies, check out our guide on how to kill O.S.C.A.R..

Contraption Part #2 – Absolute Zero Fragments (Dark Aether Crystals)

This step requires a specific ammo mod and some salvage farming:

• Collect 500 Salvage from zombies
• Head to The Arsenal and purchase the Cryo Freeze Ammo Mod
• Equip Cryo Freeze on your weapon
• Look for Dark Aether crystals scattered around the map
• Shoot these crystals with your Cryo Freeze weapon
• Collect the Absolute Zero Fragment that drops
• Repeat until you have 3 fragments total

The Dark Aether crystals are fairly easy to spot—they have that signature purple glow. Just make sure you’re using a weapon with Cryo Freeze equipped, or the crystals won’t drop anything.

Contraption Part #3 – Car Battery (Ol’ Tessie)

This one’s a bit more expensive but straightforward:

• Save up 5,000 Essence
• Pack-a-Punch any weapon
• Return to the Crash Site (the spawn area)
• Find Ol’ Tessie (the crashed car—can’t miss it)
• Look inside and locate the gear shift with a Mister Peeks head on it
• Shoot the gear shift
• The Car Battery will pop out from under the hood—grab it

Contraption Part #4 – Aberrant Wiring (Flickering Lamppost)

The final contraption part involves a bit of searching:

• Head to Stargazer’s Courtyard
• Look for lampposts with flickering lights
• Shoot the flickering lamppost
• Pick up the Aberrant Wiring that drops

If you don’t see any flickering lampposts in Stargazer’s Courtyard, keep searching other areas of the map. Only one lamppost will be flickering per game, so you might need to explore a bit.

Step 2: Kill O.S.C.A.R. with Three Different Traps

Now comes the challenging part. You’ve got all four contraption parts, and it’s time to use them to activate three unique traps across the map. O.S.C.A.R. must be killed by each trap in sequence to unlock the LGM-1 Wonder Weapon.

Trap #1 – Electro-Volt Projector (The Luminarium)

Location: The Luminarium (where Jugger-Nog is located)

• Find the large trap device in this room
• Interact with the switch labeled “ready”
• Place the Damaged Drone into the trap
• Lure O.S.C.A.R. into the room (use the Tac Map to find him)
• Interact with the switch again to activate the trap
• Stay inside the room during the timed objective
• Keep shooting O.S.C.A.R.’s drones to keep him vulnerable
• Wait for his battery to overcharge and kill him

This is a survival challenge, so make sure you’ve got good perks and decent weapons before starting. Jugger-Nog is right there, so at least you’re in a good spot for it!

Trap #2 – Thurston’s Rocket Ignition (Museum Infinitum)

Location: Museum Infinitum (Speed Cola room)

• Head to the western side of the Museum Infinitum
• Find the rocket display
• Lure O.S.C.A.R. into the room
• Stand on the south side of the rocket and interact with it
• A 5-second countdown will begin
• Quickly position O.S.C.A.R. directly behind the rocket blast area
• Let the ignition blast kill him

Important: If you mess this up, you’ll need to collect 3 more Absolute Zero Fragments using Cryo Freeze again. Take your time positioning O.S.C.A.R. correctly. The good news is you don’t have to worry about his drones for this trap.

Trap #3 – Observatory Laser (Observatory Dome)

Location: Observatory Dome (Pack-a-Punch room)

This one’s got multiple steps:

Part A: Find the Steam Valves

• Look around the Observatory Dome for hissing pipe valves releasing steam
• Check everywhere—walls, ceiling, floor
• Only one valve will be actively hissing at a time
• Shoot the correct valve
• Find and shoot the next one that starts hissing
• Repeat this 5 times total
• The observatory dial will aim downward when complete

Part B: Activate the Sun Beam

• Lure O.S.C.A.R. into the Observatory Dome
• Interact with the church organ opposite Pack-a-Punch
• This opens a telescope view
• Align the lens with the Sun (usually up and slightly left)
• A laser beam will shoot down to the ground
• Guide O.S.C.A.R. through the laser beam to kill him

Once O.S.C.A.R. dies from the third trap, he’ll finally drop the LGM-1 Wonder Weapon. Pick it up and congratulations—you’ve earned it!

How the LGM-1 Wonder Weapon Works in Black Ops 7 Zombies

Now that you’ve got the LGM-1, let’s talk about what it actually does and whether it’s worth all that effort.

LGM-1 Stats and Mechanics

The LGM-1 is unlike most Wonder Weapons you’ve used before:

• Fires UFO projectiles that home in on enemies automatically
• 3 charges that continuously replenish
• Infinite ammo—charges return after killing targets
• Fast fire rate but relatively slow kill times
• Works best as a secondary weapon while staying mobile

The unique gimmick here is that your UFO projectiles track and attack zombies independently, then return to you once the target is dead. You can fire all three charges while running around, letting the weapon do the work while you focus on movement and survival—perfect for training spots.

Upgrading to the Martian Man O’War

When you Pack-a-Punch the LGM-1, it transforms into the Martian Man O’War:

• UFOs spread in a shotgun-like pattern
• Increased damage output
• 8 charges instead of 3
• Still infinite ammo with returning projectiles

While the upgraded version is definitely better, it’s still not the best at clearing massive hordes quickly. It’s more of a consistent damage dealer than a crowd control powerhouse.

Is the LGM-1 Wonder Weapon Worth It?

Here’s my honest take: the LGM-1 is decent but not game-changing.

Pros:

• Infinite ammo means zero ammo management
• Great for O.S.C.A.R. fights (seems designed for him)
• Unique tracking mechanic is fun to use
• Excellent mobility weapon
• Free to obtain (no mystery box RNG)

Cons:

• Lower damage compared to other Wonder Weapons
• Not ideal for high-round horde clearing
• Outclassed by the Necrofluid Gauntlet, Ray Gun, and Ray Gun Mark 2
• Slow kill times can be frustrating in later rounds

The LGM-1 shines as a support weapon. Use it to distract O.S.C.A.R. while dealing chip damage, or fire it while training zombies with your primary weapon. It’s also helpful when you’re low on ammo with your other guns and need something reliable.

For players tackling Dark Ops challenges or going for high rounds, you might find better options in your loadout. But for casual runs or learning the map, it’s a solid choice.

Tips for Getting the LGM-1 Wonder Weapon Efficiently

Want to speed up the process? Here are some pro tips:

• Start early: Begin collecting contraption parts as soon as you turn on power
• Salvage first: Get your 500 salvage for Cryo Freeze as early as possible
• Essence farming: Check out our essence farming guide to reach 5,000 quickly
• Use GobbleGums: Some GobbleGums can make trap steps easier
• Practice trap timing: The rocket trap can be tricky—don’t rush it
• Coordinate in co-op: Split up contraption part collection with teammates
• Bring good gear: Have at least Jugger-Nog and a Pack-a-Punched weapon before starting trap steps
