Happy’s Humble Burger Cult 100% Achievement Guide: Full Completion Walkthrough

Psychological horror games rarely reward curiosity as generously as Happy’s Humble Burger Cult. Scythe Dev Team didn’t simply build a sequel—they expanded the bizarre universe of New Elysium into something much stranger, blending restaurant management, survival horror, environmental puzzles, and exploration into a surprisingly addictive package. Every shift feels like it could end in disaster, yet every hidden corridor or forgotten apartment room might contain the key to another achievement.

After spending dozens of hours exploring every district, intentionally failing orders, experimenting with crafting recipes, and hunting every secret, one thing became obvious: 100% completion is far more enjoyable when you know exactly what deserves your attention before it’s too late.

This walkthrough covers every achievement, explains which ones are permanently missable, and provides practical strategies that reduce unnecessary grinding while keeping your progress smooth from beginning to end.

100% Completion Overview

Before jumping into individual achievements, it’s worth understanding what kind of journey you’re signing up for.

Story Mode naturally unlocks most progression trophies, while Endless Mode works perfectly for cleaning up restaurant-related objectives without dealing with late-game story pressure.

One recommendation I’d give every new player: don’t rush the main storyline. New Elysium hides far more secrets than the game initially suggests, and several achievements disappear forever if you sprint from objective to objective.

Story Achievements You Unlock Naturally

These achievements require almost no special preparation. Simply progressing through the campaign eventually awards them.

Although these unlock automatically, a couple of boss encounters deserve extra attention.

Defeating Evil Petey

This fight can become frustrating if you panic.

Instead of randomly activating power switches, memorize the proper sequence:

• Green
• Yellow
• White
• Blue
• Red

Following this order disables Petey’s advantage and lets you finish the encounter safely.

Defeating Evil Charlie

Charlie’s hatchery looks intimidating, but the real challenge is the sonar puzzle before the fight begins.

Take your time solving the terminal rather than rushing into the arena. Once Charlie becomes vulnerable, the battle itself is fairly manageable.

Missable Exploration Achievements

Some of the easiest achievements to overlook involve areas that never become mandatory.

I Have No Mouth

Your own apartment hides far more than a bed and crafting bench.

Carefully inspect:

• Bathroom walls
• Closet
• Structural cracks

Eventually you’ll discover the hidden breach needed for this achievement.

But I Must Scream

Later in the game you’ll gain access to ventilation passages leading into restricted corporate offices.

Finding the supervisor’s hidden office awards this achievement immediately.

Backpack, Backpack

This one catches many completionists by surprise.

You’ll need:

• an extra Keypad Hacker
• access to Room 6
• electronic lock bypass

Inside waits the utility backpack required for the achievement.

Don’t waste your only hacker earlier if you know you’re chasing full completion.

Restaurant Management Achievements

Running Happy’s restaurant properly is only half the fun.

The developers clearly expected players to embrace complete chaos.

Oops

Serve one incorrect order.

That’s literally it.

Wrong burger, missing fries, burnt food—it all counts.

My Bad

Accumulate five incorrect orders during your career.

These don’t need to happen in one shift.

Let Me Speak to the Manager

Continue your culinary crimes until you’ve delivered 10 ruined customer orders.

This is cumulative and surprisingly quick if intentionally farmed.

3rd Shift

Probably one of the coolest hidden encounters in the game.

Trigger Evil Happy by serving:

• three incorrect orders
• consecutively

When she appears:

1. Keep your crosshair directly on her.
2. She freezes while watched.
3. Retrieve the rotten green-smoking burger patty.
4. Cook it.
5. Throw it directly into her mouth.

Miss any step and you’ll likely become dinner instead.

Nobody Panic!

Kitchen fires eventually happen.

Many players instinctively shut equipment off.

Don’t.

Instead:

• sprint toward the rear exit
• pull the blue emergency ceiling lever
• activate the sprinkler system

Achievement unlocked.

Spoiler Alert

Burn 10 meat patties until they’re completely black.

Honestly, this is one of the fastest achievements in the entire list.

Shopping and Economy Achievements

Money becomes incredibly important during the middle portion of Story Mode.

Finishing optional restaurant objectives dramatically reduces grinding later.

My advice?

Don’t spend money impulsively.

Several expensive apartment upgrades arrive almost back-to-back, and grinding shifts purely for cash slows the pacing considerably.

Food Consumption Achievements

These seem harmless, but they’re surprisingly easy to forget while focusing on survival.

Caffeine Rush

Drink 10 cans of Jazzy Java.

Locations include:

• local café
• Toe’s apartment
• scattered city tables

Straight to the Thighs

Consume 10 Energy Bars.

You’ll find them inside:

• vending machines
• employee break rooms
• storage areas

Because both achievements are cumulative, grab every snack you encounter.

Hidden World Achievements

This is where Happy’s Humble Burger Cult really starts showing its weird side.

Killer of Giants

Craft the advanced tracking helmet.

Equip it.

You’ll suddenly find yourself inside a mysterious hotel.

Walk onto the balcony and simply watch the horizon.

The nuclear explosion eventually appears, unlocking the achievement.

It’s one of the strangest moments in the entire game.

Deja Vu

Die.

Then die again.

Repeat until you’ve reached 10 total deaths.

Quick farming methods include:

• standing on a hot grill
• letting monsters catch you
• ignoring obvious hazards

Sometimes failure really is progress.

Escape From the Barn

One of the easiest achievements to miss.

Requirements:

• Burger Bomb
• access to Burger Barn
• freezer area

Complete the following steps:

1. Enter the meat freezer.
2. Blow open the hidden ice wall.
3. Drop into the flooded basement.
4. Rotate the red drainage valve.
5. Move behind the submerged structure.
6. Place the Burger Bomb on the truck bed.

Only after completing the entire sequence will the achievement unlock.

Best Route for 100% Completion

If your goal is unlocking every achievement in the shortest amount of time, I’d recommend this order:

• Finish every optional restaurant objective before advancing major story chapters.
• Purchase apartment upgrades as soon as cash allows.
• Explore every accessible apartment and ventilation shaft immediately.
• Always carry materials for another Keypad Hacker.
• Burn patties and intentionally fail orders early to remove tedious cleanup later.
• Leave cumulative food achievements running naturally throughout the campaign.
• Use Endless Mode only if something was missed.

Final Thoughts

Happy’s Humble Burger Cult is much more than a bizarre horror cooking simulator. Underneath the unsettling atmosphere lies a surprisingly rewarding achievement hunt that constantly encourages experimentation instead of simple checklist grinding. Some trophies ask you to become the perfect employee, while others practically beg you to sabotage the restaurant, anger customers, or intentionally get yourself killed.

That contrast is exactly what makes pursuing 100% completion so entertaining. Every achievement feels tied to the game’s twisted personality rather than existing as filler content. Hidden apartments reveal disturbing lore, optional crafting opens entirely new paths, and even something as simple as serving the wrong burger can lead to one of the game’s most memorable encounters.

If you stay curious, thoroughly search every corner of New Elysium, manage your money wisely, and avoid rushing through story objectives, earning every achievement becomes a satisfying challenge rather than an exhausting grind. By the time the credits roll and the final badge appears, you’ll have experienced nearly everything this wonderfully bizarre horror adventure has to offer.
