Look, the Liberty Falls map in Black Ops 6 is basically a love letter to classic Zombies, but it’s got one massive, noisy problem. That problem is the Jet Gun. Officially known as the Thrustodyne Aeronautics Model 23, or the DRI-11 Suction Cannon, this thing is a beast. It’s also a total pain to build if you don’t know exactly where you’re looking. If you played Tranzit back in the day, you probably remember the original Jet Gun as a fragile piece of junk that broke if you looked at it funny. Thankfully, Treyarch fixed that.
In BO6, the Jet Gun doesn’t break. It just overheats. It’s the ultimate crowd control tool, sucking zombies into a turbine and shredding them into a fine red mist. But you can't just pull it out of a wall. You have to hunt down three specific jet gun parts in BO6 scattered across the town of Liberty Falls.
It’s not just about finding the parts, though. You’ve got to trigger specific mini-events and deal with some tight RNG. Honestly, if you're trying to do the main quest Easter Egg, this isn't optional. You need it.
The Water Pressure Gauge: Starting at the Flower Shop
First thing's first. You need a valve. Head over to the Lily’s Flower Shop area. Right next to the shop, there’s a nondescript water valve attached to the wall. You need to interact with it to take it. Once it's in your inventory, your next stop is the Liberty Lane Bowling Alley.
This part is annoying.
Inside the bowling alley, on the right-hand wall, there’s a small panel you need to melee or shoot off. Once it's open, stick that valve in there. Now comes the "hold the square button" (or F, or X) mini-game while zombies try to eat your face. You have to hold the valve to increase the water pressure until the gauge fills up.
Pro tip: don't try this solo without a Decoy grenade or a Monkey Bomb. The bar resets if you let go. It takes about 10 to 15 seconds of continuous holding. If you’re playing with a squad, have your buddies run circles around the bowling lanes to keep the horde away. Once the pressure peaks, the Water Pressure Gauge pops out. That’s one down.

The Handbrake: Checking the Graves
The second of the jet gun parts in BO6 is the Handbrake. For this one, you’re heading to the cemetery. Specifically, look for a unique zombie—Groundskeeper Sawyer.
He doesn't always spawn immediately. Usually, he shows up around Round 8 or 10. He looks different from the standard shamblers; he’s wearing overalls and often hanging out near the shed or the tools. Kill him. He’ll drop the Toolshed Key.
Now, run to the back of the cemetery area where the small wooden shed is located. Unlock it, and the Handbrake is sitting right there on the workbench. It’s probably the easiest part to get, provided the Groundskeeper actually decides to show up. Sometimes he wanders a bit toward the church, so keep your eyes peeled for a zombie that looks like he’s lost his lawnmower.
The Electrical Wire: Scavenging the Radio House
The final piece is the Electrical Wire. This one sends you to the Riverside area, specifically the Radio House (the electronics store).
You can't just walk in and grab it. You need a specific tool: the Manglers Cannon. You can either wait for a Mangler to spawn naturally and blow its arm off to drop the cannon, or you can craft a Mangler Support streak at a Crafting Table if you’ve got the salvage.
Take that Mangler Cannon to the front of the Radio House. The front door is barred by a metal gate. Fire the cannon at the gate to blast it open. Once you’re inside, you’re looking for piles of junk on the floor. You have to interact with the various piles of electronic scrap.

It’s random.
Sometimes it’s in the first pile you check, sometimes it’s the last one near the back counter. Just keep holding the interact button on the floor debris until the Electrical Wire appears. Now you have all three pieces.
Building the Thrustodyne Model 23
With all the jet gun parts in BO6 in your pockets, head to the second floor of the Motel. This is the starting area of the map. Room 202 is where the magic happens.
Inside, there’s a workbench. Interact with it, and after a few seconds of assembly animation, you’ll be holding the most powerful vacuum cleaner in video game history.
Why the Jet Gun is actually good now
The BO6 version of this weapon is significantly improved over the BO2 version. It has a primary fire that sucks enemies in and a secondary fire (the blast) that clears a path.
- Infinite Ammo: It works on a cooling system. If you red-line it, you have to wait for it to cool down.
- Easter Egg Essential: You need this to suck up the LTG parts scattered around the map.
- High Damage: At base level, it chews through normal zombies instantly.
However, there’s a catch. The "sucking" mechanic slows your movement speed. If you get cornered while using it, you’re dead. You have to learn the rhythm of pulsing the trigger rather than just holding it down. Think of it like a burst weapon.

Hidden Details and Misconceptions
A lot of players think you need to Pack-a-Punch the Jet Gun to make it viable for high rounds. While you can upgrade its damage, its primary utility is the pull effect. In Liberty Falls, the verticality of the map means you can sit at the top of the stairs in the Church or the Motel and just pulse the Jet Gun to keep the entire lane clear.
Another common mistake? Thinking the Groundskeeper is a "boss." He’s not. He has the health of a slightly buffed normal zombie. Don’t waste a Scorestreak on him. A few headshots with a common pistol will do the job.
Also, regarding the Radio House step: if you accidentally kill the Mangler and he doesn't drop the cannon, don't panic. Another one will spawn in a round or two. Or, just save up 2,500 Salvage and buy the Mangler Cannon from the bench. It’s faster and saves the headache of kiting a Mangler through the narrow streets of Liberty Falls.
Actionable Next Steps for Your Run
To make this process efficient, you should aim to have the Jet Gun built by Round 11. Any later and the zombies become too fast to safely do the valve step in the bowling alley.
- Round 1-5: Focus on opening doors toward the Bowling Alley and the Flower Shop. Grab the valve immediately.
- Round 6-8: Get to the cemetery. Look for the Groundskeeper. If he's there, kill him, grab the key, and get the Handbrake.
- Round 9-10: By now, a Mangler should have spawned. Use his cannon to break into the Radio House.
- Final Step: Run back to the Motel, build the gun, and start the main Easter Egg steps.
The Jet Gun is your ticket to high-round survival in Liberty Falls. It makes the "Holdout" objectives significantly easier and is the only way to progress the story. Just watch that temperature gauge; the last thing you want is a jammed turbine when a Mangler is charging at you.
