You’re dropped into a sunny, deceptively quiet West Virginia town, but within ten minutes, the sky turns purple and everything goes to hell. That's Liberty Falls. If you’re trying to figure out how to do the Liberty Falls easter egg, you’ve probably already realized it’s a massive step up in complexity from the old-school "turn on the power" days of Black Ops. It’s a multi-stage puzzle that requires precision, a bit of luck with the Jet Gun, and the ability to survive a chaotic boss fight in the church. Honestly, if you aren't prepared, the final encounter will wipe your squad in seconds.
Most players struggle because they treat it like a standard survival map. It isn’t. You need to be thinking three steps ahead, specifically about which tools you're crafting and when you're choosing to "lock in" your round.
Getting the Thrustodyne M23 (The Jet Gun)
You can't even start the main quest without the Jet Gun. While you can pull it from the Mystery Box if you're feeling lucky, you're better off building it. It’s guaranteed. First, head to the Lily’s Flower Shop and grab the tools. You’ll need to find three specific parts: the Water Pressure Gauge, the Handbrake, and the Electrical Wires.
The gauge is tucked away in the Washington Avenue area. You have to find a specific valve on the wall—near the bowling alley—and hold your interact button until the needle hits the red. This triggers a wave of zombies. Kill them, and the gauge pops off. For the handbrake, you’re looking at the groundskeeper's shed near the cemetery. It’s usually just sitting there, but sometimes you have to scavenge a bit. The wires? Go to the Radio Station and look for a pile of debris you can interact with.
Once you have all three, head to the second floor of the motel. There’s a workbench in one of the rooms. Build it. This weapon is your bread and butter for the rest of the run. It sucks up zombies and, more importantly, it sucks up the quest items you can't reach by hand.
Calibrating the LTG Devices
After you have the Jet Gun, head to the church. You'll meet Panos, or at least hear him. He wants you to fix the LTG devices. This is where things get annoying. You need to find two canisters. One is on top of the florist shop, and the other is on a white van near the gas station. You can't just jump up there; you have to use the Jet Gun's secondary fire (the vacuum) to pull them down.
Take these to the machine in the church. Now, you need to "trap" a high-value target. This isn't a normal elite. You have to place the LTG device in a specific spot—usually the graveyard or the riverside—and defend it while it charges. It creates a purple lightning field. You need to weaken a Mangler or a Thrasher inside that field and then deploy the canister to capture its soul.
If you kill the elite outside the circle, you've wasted your time. Start over. It’s frustrating. But once you have a captured soul, bring it back to the church. You have to do this twice. One for each canister.
The Projection and the Map Sync
The next step in how to do the Liberty Falls easter egg involves the projector in the library. You'll see a map of the town projected on the wall. This is a logic puzzle. You need to find three laptops scattered around the map: one in the comic book shop, one near the bowling alley, and one by the church entrance.
These laptops display coordinates. You have to match the colors on the laptop screens to the symbols on the projector. It sounds simple, but when you have thirty zombies chewing on your ankles, it's easy to misread a "B" for an "8." Once the coordinates are synced, the map will glow gold. This signals that the final encounter is ready.
Make sure you have your perks. Juggernog and Quick Revive are non-negotiable here. I’d also highly recommend Stamina-Up because the final arena is cramped, and if you stop moving, you’re dead.
Surviving the Church Boss Fight
The "boss" isn't a single giant monster, but a scripted gauntlet inside the church. Once you interact with the machine for the final time, the doors lock. You are trapped in a very small space with an infinite spawn of elites.
The screen goes dark, and Panos starts yelling. You'll face waves of Abominations and shielded Manglers. The trick here is the Jet Gun. Use the primary blast to clear paths, but save the vacuum for the purple orbs that float near the ceiling. These orbs heal the bosses. If you don't suck them up, the fight lasts forever.
Many people think you just have to outlast the timer. You don't. You have to deal a specific amount of damage to the central containment unit while surviving the onslaught. Use your Support streaks now. A Chopper Gunner won't help you inside a building, so bring Sentry Turrets or a Death Machine. Place the Sentries near the altar to cover your back while you focus fire on the elites.
Why Speed is Your Best Friend
Don't drag this out. The zombies in Liberty Falls scale aggressively. If you're trying to do the boss fight on Round 25, you’re going to have a bad time. The sweet spot is Round 12 to 15.
At this stage, the elites have significantly less health, and you can one-shot most basic zombies with a Pack-a-Punched pistol. If you spend too much time hitting the Mystery Box for a Ray Gun, you’re just making the endgame harder for yourself.
Essential Checklist for Success:
- Pack-a-Punch Level 2: Do not enter the church with a base weapon. Your Jet Gun should also be upgraded if possible.
- Decoy Grenades: These are better than Monkeys in this map. They throw faster and give you that three-second window to interact with the LTG devices.
- Armor Plates: Buy the Level 3 vest at the crafting table. The Abominations in the church have a beam attack that shreds Level 1 armor instantly.
- Mutant Injection: If you're playing solo, this support item is a life-saver. Turning into a Mangler for 30 seconds gives you breathing room when you're cornered.
The story implications of the Liberty Falls ending are massive. You see the rift stabilize, and the "Janus" project is revealed to be far more sinister than the initial cinematics suggested. Once the cutscene plays, you’re rewarded with a massive XP dump and a unique calling card. More importantly, you unlock the ability to see the "hidden" loot caches in future runs, which makes high-round attempts much easier.

Go get your gear ready. Focus on building the Jet Gun by Round 6, capture your souls by Round 10, and you’ll be watching the ending cinematic before the difficulty spike even hits.
Once the boss falls, don't forget to grab the loot drops on the floor before the game ends; there's usually a guaranteed Legendary tool and a Flawless Aetherium Crystal waiting for you near the altar. Pack your bags, stay mobile, and keep your back to the church walls.
