Liberty Falls easter egg guide at 100% in CoD Black Ops 6 Zombies: All steps

Liberty Falls is an engaging map found in the Zombie mode of Call of Duty: Black Ops 6. As is typical in this franchise, this map features a main easter egg that players can complete by following a specific series of tasks and objectives spread throughout the area while battling waves of the undead.

Completing this easter egg can be quite difficult without help, as many required tasks are either hidden or not entirely straightforward. However, this guide will assist you through all the necessary steps to successfully complete the easter egg, which can be tackled solo or with others (though teaming up is generally easier). To achieve success, follow the objectives outlined below.

First Step: Create the Thrustodyne M23

Your first task in this easter egg is to make your way to the church building. Once inside, interact with the machine on the right wall to trigger the easter egg storyline.

After starting the mission, your main objective will be to assemble the impressive Thrustodyne M23, also referred to as the Jet Gun. While you can find it in mystery boxes, crafting it directly is a more dependable option. To accomplish this, gather a series of materials, specifically three items that can be collected in any order:

Acquire the Handbrake

• Go to the graveyard next to the church and start eliminating groups of zombies.
• After defeating enough, a special zombie known as the “Gardener” will spawn.
• Take out the Gardener and collect the “Shed Key” it drops.
• Next, head to the yard of the house adjacent to the graveyard.
• In this yard, open the wooden shed door (even if no button appears, you can use the key) to find the handbrake piece inside.

Obtain the Pressure Gauge

• Proceed to Washington Ave and head toward the florist shop called Lily’s Flowerpot.
• To the right of the shop’s entrance, grab the water valve from a hose.
• Then, enter the bowling alley named Liberty Lanes.
• On the right wall of the bowling lane, break the water pressure panel with a shot or melee attack.
• Attach the valve to the panel and hold the button to gradually increase the pressure.
• Be mindful that while pressure rises, waves of zombies will attack. If you exit the bowling alley, your progress will reset.
• Once the water pressure is at maximum, the pressure gauge piece will appear, allowing you to collect it.

Collect the Electric Cables

• First, you will need a mutilator cannon; you can obtain one by defeating elite enemies or crafting it at a workbench using 1250 essence.
• Once you have the cannon, head to the Radio House electronics store near the gas station and comic shop.
• Break the gate at the entrance with a shot from the cannon to gain access to the store.
• Once inside, look for cable mounds on the floor and interact with them to lift them. Under one of these, you will find the electric cables piece.

Where to Assemble the Thrustodyne M23

After gathering the materials mentioned above, go to the second floor of the motel at the map’s starting point, where a horde of zombies will emerge from one of the rooms.

Defeat them and enter the room to find a workbench to assemble all the pieces and obtain the Thrustodyne M23. From this point, you can utilize the weapon for the remainder of your game.

Second Step: Construct the PTL

Your next task in the easter egg is to build the PTL device. To do this, you need to absorb up to three distinct pieces using the Thrustodyne M23 found in the following locations:

First PTL Piece

• Go to Washington Ave and climb the slope next to Lily’s Flowerpot.
• Midway up the street, climb the wall on your left and access the roof of that building.
• From the roof, jump onto the white truck parked on the street.
• Once on the truck, use the absorption feature of the Thrustodyne M23, aiming towards the open window of the second floor of Buzz’s Cuts hair salon (this will draw the PTL piece towards you).

Second PTL Piece

• Enter Olly’s Comics store.
• Stand at the center counters and look up at the ceiling of the shop.
• You will see the PTL piece floating among the broken ceiling tiles.

Third PTL Piece

• Go inside the church building (remember to interact with the machine on the right wall if you haven’t already).
• Look up towards the upper floor above the entrance to find this PTL piece floating.

Where to Assemble the PTL

After collecting the three pieces, head to the roof of the large bank building (the same one with the locked safe). On the roof, you will discover a workbench to assemble the pieces and create the PTL.

Third Step: Acquire the Strauss Counter

With the PTL in your possession, it’s time to obtain the Strauss Counter. First, make your way to one of the ether storm clouds (such as the one near the music store parking lot or the church graveyard).

Place the PTL in the center of the storm’s ground, and waves of zombies will emerge to attack the device. Ensure you defeat them all (if you fail, you can try again in the next round). Once you’ve taken out all the zombies, a unique elite enemy will spawn.

Ignore the enemy for now. Quickly return to the church and check the machine on the right wall to collect a jar of ether. Then, proceed to Washington Ave and drop the jar of ether near the electric trap next to Lily’s Flowerpot.

Wait for the elite enemy to arrive and start chipping away at its health. When it is nearly defeated, Panos will alert you that it’s time to capture its energy in the ether jar. To do this, activate the dark ether field generator nearby (the machine that powers the electric trap on the ground). While the trap is active and shocking the elite enemy, finish it off to fill the ether jar. Then, rush back to the church before time runs out to insert the jar into the machine and acquire the Strauss Counter.

Fourth Step: Recalibrate Devices with the Strauss Counter

Now, you need to obtain a second ether jar. To do this, locate a series of devices where you can use the Strauss Counter to calibrate their power. These devices can be found in the following locations:

• Device #1: located in the same yard of the Gardener’s house that has the shed where you previously used the key.
• Device #2: found down the stairs in front of the church, on the hill in front of the bowling alley and a bus.
• Device #3: located on the roof of Yummy Freeze; to reach it, go up to the bank building’s roof and break the wooden panel to jump down onto the roof.

When near these devices, use the Strauss Counter and aim at the purple orbs floating in the air to see what type of power the electromagnetic field has. The counter screen may display red (high power), orange (medium power), or green (low power).

You simply need to recalibrate the power of the device by interacting with it. If the counter shows high power, adjust the machine to low power. If it shows low power, do the opposite and set the machine to high. If it’s orange, set the machine to orange as well.

Once you successfully recalibrate all three devices, a beam will emerge from each, leading to the starting area. Follow the beams to reach a machine where you can collect a second ether jar.

Fifth Step: Activate the PDS Generator

Your objective now is identical to step three: you need to fill the second ether jar you just collected to activate the PDS generator in the church and complete the easter egg. So, you know what to do…

You need to place the PTL in a storm area until a mini-boss appears, then electrocute it with a dark ether trap to eliminate it and capture its energy in the jar.

After completing this step, all that remains is to take the ether jar to the machine inside the church to activate the PDS generator and start the final encounter of the easter egg. Make sure to prepare adequately before beginning the battle, as it will be a very tough encounter against three phases of zombie hordes, including several elite enemies (and the space is quite limited).

At the end of the battle, the zombies will knock you down, but this is part of the easter egg. You will soon see the final cutscene and successfully complete the quest.
