ULTRAKILL Achievement Guide (TREACHERY UPDATE)

ULTRAKILL is the kind of game where achievements are not just simple checklists. Some unlock naturally while progressing through the story, while others require mastery of movement, combat mechanics, hidden secrets, and even specific ending choices. With the TREACHERY update adding more late-game content, the achievement list has become much bigger and more challenging than before.

This guide covers every achievement currently available in ULTRAKILL, including story unlocks, boss achievements, missable content, Prime Sanctums, Cybergrind goals, and the Platinum achievement. I’ll also explain the easiest ways to unlock them and point out the achievements that can permanently be missed if you are not careful.

And yes, massive spoilers ahead.

Story Achievements

Most story achievements unlock naturally while progressing through the campaign. If you are simply playing through levels normally, you will earn many of these without even trying.

Together, We Are ULTRAKILL

Unlock Requirement:

• Start the game

This achievement unlocks immediately after entering the PRELUDE for the first time. Basically impossible to miss.

I Have No Mouth, And I Must Kill

Unlock Requirement:

• Die for the first time

Considering how aggressive ULTRAKILL is, this achievement usually appears very early unless you are somehow already a speedrunning god.

Are You Even Trying?

Unlock Requirement:

• Die 100 times

Honestly, most players will eventually unlock this naturally. ULTRAKILL becomes brutally difficult later, especially during higher difficulties and optional content.

Do not feel bad about this achievement. Even experienced players die constantly while learning advanced movement and enemy patterns.

Devil Could Cry

Unlock Requirement:

• Defeat every Husk enemy type

You do not need every variation of enemies for this achievement. Only the base enemy categories matter.

As long as you naturally progress through the game and fight most encounters, this unlocks automatically.

Arms Race

Unlock Requirement:

• Defeat every Machine enemy type

Same idea as the previous achievement. Variants do not count separately.

Machine enemies become much more dangerous later once stronger versions begin appearing in larger groups.

Exorcism

Unlock Requirement:

• Defeat every Demon enemy type

This unlocks naturally while progressing through later acts.

Be (Not) Afraid

Unlock Requirement:

• Defeat every Angel enemy type

Angel enemies are far less common than Husks or Machines, so this achievement may unlock later than expected.

Supreme Machine

Unlock Requirement:

• Become an Uber Series Machine

This achievement requires:

• Defeating both V2 encounters
• Defeating V3
• Obtaining the Doctrine Yellow Arm from Gabriel in 9-1: DREAM OF FINLAND

This is one of the more important progression achievements because it ties directly into the game’s late-game story developments and weapon progression.

Boss Achievements

Most major bosses have their own achievements tied directly to defeating them.

Some are automatic story unlocks, while others can be missed depending on your decisions.

Seeing Double

Unlock Requirement:

• Defeat V2 in 1-4: CLAIR DE LUNE

This is the first V2 fight and one of the biggest skill checks early in the game.

Learning movement, parrying, and aggression becomes essential here.

Reconstruct WHAT?!

Unlock Requirement:

• Defeat V2 in 4-4: CLAIR DE SOLEIL

The second V2 fight is significantly harder than the first.

V2 becomes faster, more aggressive, and punishes hesitation much harder.

Honestly, this is usually the fight where players truly begin understanding ULTRAKILL combat flow.

Eat Your Greens (MISSABLE)

Unlock Requirement:

• Defeat V3 in E-4: CLAIR DE ÉTOILE

This achievement is missable because E-levels are optional secret content.

If you skip exploring hidden stages, you may completely miss this boss.

RAISON D’ETRE

Unlock Requirement:

• Defeat 1000-THR “Earthmover”

Unlocked during:

• 7-4: …LIKE ANTENNAS TO HEAVEN

This fight is massive both visually and mechanically. The Earthmover battle feels more like fighting a living war machine than a traditional boss.

You An Insignificant..

Unlock Requirement:

• Defeat Gabriel, Judge of Hell

Unlocked during:

• 3-2: IN THE FLESH

Gabriel is one of the game’s most iconic fights and probably the first boss that forces players to fully master movement.

I Might Be Atheist

Unlock Requirement:

• Defeat Gabriel, Apostate of Hate

Unlocked during:

• 6-2: AESTHETICS OF HATE

This version of Gabriel is significantly more dangerous and much faster than the earlier fight.

Aggressive play becomes almost mandatory here.

Golden Ratio (MISSABLE)

Unlock Requirement:

• Help Gabriel realize his folly
• Obtain the Doctrine Yellow Arm

This achievement is tied directly to story choices during the TREACHERY content.

Missing the correct sequence can permanently lock the achievement for that playthrough.

Paint The World RED (MISSABLE)

Unlock Requirement:

• Kill Gabriel and embrace endless slaughter
• Unlock the Bad Ending

Unlocked during:

• 9-2: ENIGMA OF HEAVEN: 9,999,999

This is one of the ending achievements and requires specific choices near the conclusion of the TREACHERY storyline.

Theatrical Finale (MISSABLE)

Unlock Requirement:

• Defeat HELL ITSELF alongside Gabriel
• Unlock the Good Ending

Also unlocked during:

• 9-2: ENIGMA OF HEAVEN: 9,999,999

Unlike the Bad Ending, this route focuses on cooperation with Gabriel rather than total destruction.

Because both ending achievements are mutually exclusive during a single route, multiple playthroughs or reloads are recommended.

Collectibles And Secret Content

These achievements require exploration and completionist behavior rather than raw combat skill.

Collect ‘Em All

Unlock Requirement:

• Find every collectible in the game

ULTRAKILL hides many secrets extremely well. Some collectibles require careful observation, hidden paths, or advanced movement techniques.

Fully Strapped

Unlock Requirement:

• Collect all weapons and variants

This includes alternate weapon versions and hidden unlocks throughout the campaign.

Some variants are surprisingly easy to overlook if you rush levels.

Handshake

Unlock Requirement:

• Collect every arm variant

Important warning:

This achievement becomes missable if you kill Gabriel during 9-1: DREAM OF FINLAND.

If you want full completion, pay close attention during the TREACHERY story route.

P-Rank Achievements

P-Ranking is where ULTRAKILL becomes truly brutal.

To earn a P-Rank, you must achieve:

• S Rank in Style
• S Rank in Time
• S Rank in Kills
• Zero deaths
• No restarts

And yes, Encore stages count too.

Ooh, Shiny

Unlock Requirement:

• Earn your first P-Rank

Usually this happens during an earlier level once players fully understand movement routing and style chaining.

Touch Some Grass

Unlock Requirement:

• P-Rank every level

This is one of the hardest achievements in the entire game.

Some later levels become incredibly demanding because they require near-perfect movement and deep knowledge of enemy spawns.

Expect many retries.

Prime Sanctum Achievements

Prime Sanctums are optional ultra-hard boss stages unlocked through P-Ranking entire acts.

These fights are considered some of the hardest content in ULTRAKILL.

Forgive Me, My Children

Unlock Requirement:

• Defeat Minos Prime

Unlocked in:

• P-1: SOUL SURVIVOR

Minos Prime is where many players realize just how difficult ULTRAKILL can become.

His speed and aggression are absolutely relentless.

You Shall Do As An Appetizer

Unlock Requirement:

• Defeat Sisyphus Prime

Unlocked in:

• P-2: WAIT OF THE WORLD

Sisyphus Prime pushes difficulty even further.

This fight demands complete mastery of movement, parrying, and reaction timing.

Lucifer, My Love (SECRET ACHIEVEMENT)

Unlock Requirement:

• Defeat Lucifer Prime

Unlocked in:

• P-3: FALLEN FROM THE HEAVEN

Currently one of the most difficult encounters in the entire game.

This boss feels designed specifically for veteran players who already mastered every mechanic.

Cybergrind Achievements

Cybergrind is accessible directly from the main menu and acts as ULTRAKILL’s endless survival mode.

Cybergrinded

Unlock Requirement:

• Enter Cybergrind

You unlock this achievement immediately after dropping onto the platform for the first time.

Cybergore

Unlock Requirement:

• Reach Wave 999 in Cybergrind

This is probably one of the rarest achievements in the game.

Reaching Wave 999 requires absurd endurance, consistency, and skill.

Even top players struggle with this challenge.

Artistic Nature

Unlock Requirement:

• Visit the Developer Museum

To unlock this:

• Enter the museum
• Walk to the fountain near the start

Simple, but very easy to miss if you never explore menu extras.

Platinum Achievement

FREE WILL IS A FLAW

Unlock Requirement:

• Earn every achievement in ULTRAKILL

This is the true completionist achievement and easily one of the hardest Platinum-style achievements in modern shooters.

Between P-Ranks, Prime Sanctums, Cybergrind progression, hidden collectibles, and multiple endings, fully completing ULTRAKILL takes serious dedication.

Missable Achievement Warnings

Several achievements can permanently be missed depending on your choices:

• Eat Your Greens
• Golden Ratio
• Paint The World RED
• Theatrical Finale
• Handshake

If you are attempting 100% completion, it is highly recommended to keep backup saves before entering the TREACHERY finale sections.

ULTRAKILL’s achievement list perfectly matches the game itself: fast, difficult, chaotic, and incredibly rewarding once mastered.

Some achievements unlock naturally just from enjoying the story, while others demand near-total mastery of movement tech, combat systems, hidden secrets, and advanced mechanics. The TREACHERY update especially added much more replay value through alternate endings, late-game bosses, and additional missable content.

The hardest achievements honestly feel less like checklist objectives and more like proof that you truly learned how to play ULTRAKILL at its highest level.
