The LGM-1 Wonder Weapon has arrived in Black Ops 7 as part of the Astra Malorum map, and finding it will make your life a lot easier on the new map.
There are a bunch of activities that you’ll need to complete to get the LGM-1 added to your inventory. This guide will list all the steps to help you figure it out. I will be adding more screenshots and details (this guide will still have all the required information needed to unlock the weapon).
How to obtain the LGM-1 in Black Ops 7 Zombies Astra Malorum
The process of obtaining the weapon begins by completing a bunch of easier tasks. These tasks will provide you with essential quest items necessary for getting the LGM-1.
- Collect a crashed UFO by destroying an O.S.C.A.R.
- Find any blinking lamp post and shoot at it. You’ll obtain wires.
- Shoot at the gear stick on Ol’ Tessie to drop a car battery. You’ll need to use a gun with at least one Pack-A-Punch upgrade.
- Apply Cryofreeze on a weapon of your liking. Shoot an Aether Crystal with the gun to drop a shard. Repeat this process until you get three shards.
Once you have found all the items, bring an O.S.C.A.R. to the Museum and interact with the Rocket. This will start a countdown. Make O.S.C.A.R. stand behind the Rocket’s thrusters, and this will instantly kill it. Do this before the countdown expires.

Next, lure another O.S.C.A.R. to the Luminarium. Interact with the trap present at this location, and add the car battery to it. This will allow you to activate the trap and kill the O.S.C.A.R.

The next step involves bringing yet another O.S.C.A.R. to the Observatory. You’ll find several steaming valves; shoot those. There are several vaves, all present at the PAP room. There’s apparently a time limit, and you’ll have to shoot all of them before it expires. If you get the job done correctly, you’ll notice that the telescope is moving.

Interact with the big piano, and it will take you to a screen for you to focus the telescope. Check out the sun (bright yellow star). Once you find the O.S.C.A.R. on the platform, activate the Sun laser trap. You’ll need to time this carefully. Once the O.S.C.A.R. is dead, he will drop the LGM-1 Wonder Weapon.
The new Wonder Weapon isn’t the only secret to decode, since you can find three Mister Peeks headphones spread all over the map.
