The Alters Achievement Guide: Complete 100% 

The Alters follows Jan Dolski as he clones alternate versions of himself to survive a hostile planet, and its 56 achievements are split between straightforward story progress and branching choices that lock you out of other endings entirely. Since several achievements are mutually exclusive within a single playthrough, this guide lays out exactly which choices lead where and how to plan your save files to catch everything with the fewest replays.

Quick Stats

• Total Achievements: 56
• Estimated Completion Time: 25-35 hours across multiple playthroughs
• Difficulty: 6/10
• Online Required: No
• Missable Achievements: Several are mutually exclusive by design; a single playthrough cannot capture every ending or Alter storyline, so save file management across at least 2-3 runs is necessary

Achievements by Category (Detailed)

Story Progression

The survivor

Unlock Rate: 96.4% (Common)

Requirement: Reach the base

How to Unlock: Progress through the opening crash sequence until Jan reaches the mobile base for the first time.

Tips: This unlocks within the first few minutes of starting the game, so it’s effectively guaranteed.

Let’s roll

Unlock Rate: 82.3% (Common)

Requirement: Finish the Prologue

How to Unlock: Complete the game’s opening Prologue sequence before Act 1 begins.

Tips: This is a straightforward story milestone with no special conditions attached.

Nothing’s gonna stop us

Unlock Rate: 53.5% (Common)

Requirement: Finish Act 1

How to Unlock: Complete all of Act 1’s story content and transition into Act 2.

Tips: Unlocks automatically as part of normal story progression.

Into the storm

Unlock Rate: 33.6% (Uncommon)

Requirement: Finish Act 2

How to Unlock: Complete all of Act 2’s story content, including the treatment path decision, and transition into Act 3.

Tips: This is where the Corporate Plug vs. Bold Science choice locks in, so make a manual save before this point if you want to replay the other path later.

Time to go home

Unlock Rate: 27.0% (Rare)

Requirement: Finish Act 3

How to Unlock: Complete Act 3 and reach any of the game’s possible endings.

Tips: This unlocks regardless of which specific ending you get, so it’s guaranteed on any completed playthrough.

Base Building

Dig Deeper

Unlock Rate: 87.1% (Common)

Requirement: Set up the first outpost

How to Unlock: Build your first mining outpost using the base’s resource extraction systems.

Tips: This is an early-game milestone you’ll reach naturally within the first hour or two of play.

Look at all this new space!

Unlock Rate: 57.4% (Common)

Requirement: Expand the base for the first time

How to Unlock: Use accumulated resources to trigger the base’s first expansion, adding new room slots.

Tips: Base expansions are tied to Rapidium Ark progress, so this comes naturally as you follow the main story’s resource demands.

Jan’s Moving Village

Unlock Rate: 27.0% (Rare)

Requirement: Expand the base to maximum capacity

How to Unlock: Continue expanding the base through every available expansion tier until it reaches its maximum size.

Tips: This requires consistent resource investment across a full playthrough, so prioritize expansions when the option becomes available rather than delaying them.

Smart Management

Unlock Rate: 64.3% (Common)

Requirement: Start a production uphold

How to Unlock: Set up any ongoing automated production chain at the base.

Tips: This unlocks the first time you configure a sustained resource production loop, which happens naturally as you build out your base economy.

Advanced industry

Unlock Rate: 63.1% (Common)

Requirement: Create the first portion of resources using the Refinery

How to Unlock: Build a Refinery module and process raw materials into refined resources for the first time. Refiner Jan is the ideal specialist to operate it, converting enriched metals into usable metals and organic substances.

Tips: Assign whichever Alter has the Refiner specialization to operate this module for the most efficient output.

The Bridge

Unlock Rate: 55.2% (Common)

Requirement: Build a bridge over the lava river

How to Unlock: Construct the bridge module needed to cross the lava river encountered during the story.

Tips: This is a story-required construction, so it happens naturally when you reach the relevant point in the narrative.

The Ultimate Builder

Unlock Rate: 9.2% (Very Rare)

Requirement: Build all possible modules

How to Unlock: Construct every available base module type across a single playthrough.

Tips: This requires deliberate planning around your resource budget, since building every module type takes considerably more materials than a story-focused playthrough would normally use.

Provide more

Unlock Rate: 43.3% (Uncommon)

Requirement: Build the second Rapidium Ark

How to Unlock: Construct your second Rapidium Ark. You can only build one Ark per base expansion after the first one required by Maxwell, and once placed, an Ark cannot be removed (though it can be relocated within the base).

Tips: Plan your base expansions around Ark placement in advance, since each Ark permanently occupies a slot once built.

We needed that

Unlock Rate: 30.5% (Uncommon)

Requirement: Build the third Rapidium Ark

How to Unlock: Continue building Rapidium Arks, reaching your third one.

Tips: The more Arks you build, the more favorably Lucas views your decisions, so this ties into both story tone and achievement progress.

The mission comes first

Unlock Rate: 24.1% (Rare)

Requirement: Build the fourth Rapidium Ark

How to Unlock: Continue building Rapidium Arks, reaching your fourth one.

Tips: This requires committing to base expansion consistently rather than rushing through story beats.

Exceed all expectations

Unlock Rate: 19.5% (Rare)

Requirement: Build the fifth Rapidium Ark

How to Unlock: Build your fifth and final Rapidium Ark, completing the full upgrade skill in the technology tree along with reaching maximum base level.

Tips: This is the last Ark-related achievement, so pair your final playthrough’s late-game resource surplus toward completing this rather than other side objectives.

Who else is there?

Unlock Rate: 63.1% (Common)

Requirement: Upgrade the Quantum Computer

How to Unlock: Invest resources into upgrading the base’s Quantum Computer module for the first time.

Tips: This is a relatively early and low-cost upgrade, so most players complete it naturally without extra effort.

Alter Creation & Interaction

Two of us

Unlock Rate: 83.6% (Common)

Requirement: Create the first Alter

How to Unlock: Use the Quantum Computer to clone your first Alter version of Jan.

Tips: This is a core, unmissable story beat early in the game.

Baaa!

Unlock Rate: 82.9% (Common)

Requirement: Pet the sheep

How to Unlock: Find and interact with the sheep encountered during exploration to pet it.

Tips: This is a simple, optional interaction easily done the first time you come across the sheep in the world.

We Made It Together

Unlock Rate: 63.1% (Common)

Requirement: Survive the magnetic storm

How to Unlock: Successfully protect the base and crew through a magnetic storm event.

Tips: Make sure your shields and structural upgrades are in reasonable shape before a storm hits, since failing to prepare risks losing crew members.

In shield I trust

Unlock Rate: 41.7% (Uncommon)

Requirement: Walk into an anomaly 20 times

How to Unlock: Deliberately walk into environmental anomalies 20 times. Touching an anomaly raises radiation exposure, but an anomaly shield item protects you from the resulting damage.

Tips: Equip an anomaly shield before attempting this, since repeatedly taking radiation damage without one is a needless risk to Jan’s health.

I Found You

Unlock Rate: 30.0% (Uncommon)

Requirement: Find the rebel base

How to Unlock: In Act 3, follow the wheel tracks, pass through the foggy area, and turn right into the cave at the end where light shines through the rock to find the rebel base.

Tips: This location is easy to miss if you’re rushing through Act 3’s main path, so keep an eye out for the wheel tracks leading off the main route.

Reunited

Unlock Rate: 18.4% (Rare)

Requirement: Convince the rebels to come back

How to Unlock: After finding the rebel base, successfully persuade the rebel Alters to return to the crew. Note that rebels cannot be persuaded back if you’ve committed to Maxwell’s route and already given the resource collection task tied to storm preparation; provide the resources they need before the second magnetic storm, or they may die.

Tips: If you’re pursuing Maxwell’s path, be mindful that giving the resource-collection task removes the option to talk the rebels back, so plan which achievements you’re prioritizing on this playthrough.

Not Just An Object

Unlock Rate: 2.7% (Ultra Rare)

Requirement: Give every Alter at least one personal item

How to Unlock: Provide a personal item to every Alter in your crew across the course of a playthrough.

Tips: Personal items are given through specific dialogue and interaction opportunities with each Alter, so pay attention to those options as they come up rather than skipping through conversations.

All by myselves

Unlock Rate: 2.5% (Ultra Rare)

Requirement: Create all possible Alters

How to Unlock: Clone every available Alter specialization across a single playthrough (Technician, Scientist, Botanist, Miner, Worker, Refiner, Guard, Doctor, Shrink, and Tabula Rasa where applicable).

Tips: This requires careful resource planning since each additional Alter increases your base’s upkeep demands, so build toward this deliberately rather than incidentally.

Alter Lessons

Assertiveness

Unlock Rate: 56.8% (Common)

Requirement: Learn the Technician’s lesson – Assertiveness

How to Unlock: Progress the Technician Alter’s storyline, including building the first Rapidium Ark, until he questions why you’re blindly following corporate orders. Agree with him to receive his lesson on assertiveness.

Tips: This lesson ties directly to Ark-building progress, so it comes up naturally as you follow the main resource objectives.

Pragmatism

Unlock Rate: 33.2% (Uncommon)

Requirement: Learn the Scientist’s lesson – Pragmatism

How to Unlock: Progress the Scientist Alter’s storyline; in Act 1, usually after the first storm, he’ll bring up learning to make practical compromises.

Tips: Keep the Scientist Alter engaged in dialogue after major story beats like storms, since his lesson is tied to these check-in conversations.

Reliance

Unlock Rate: 33.1% (Uncommon)

Requirement: Learn the Botanist’s lesson – Reliance

How to Unlock: Progress the Botanist Alter’s storyline through his available dialogue and interaction opportunities to receive his lesson.

Tips: The Botanist’s arc ties into several ending paths later, so following his storyline closely also helps set up other achievements like The things we do for love or I deserved this more.

Optimism

Unlock Rate: 20.3% (Rare)

Requirement: Learn the Refiner’s lesson – Optimism

How to Unlock: Progress the Refiner Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Refiner needs to be created and actively used at his module for his storyline dialogue to trigger reliably.

Vulnerability

Unlock Rate: 19.1% (Rare)

Requirement: Learn the Miner’s lesson – Vulnerability

How to Unlock: Progress the Miner Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Miner doesn’t require the implant treatment path to complete his personal storyline, despite some assumptions to the contrary.

Charisma

Unlock Rate: 9.1% (Very Rare)

Requirement: Learn the Worker’s lesson – Charisma

How to Unlock: Progress the Worker Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Worker’s storyline tends to appear later in a playthrough, so make sure he’s an active crew member rather than left in stasis.

Chill

Unlock Rate: 9.0% (Very Rare)

Requirement: Learn the Shrink’s lesson – Chill

How to Unlock: Progress the Shrink Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Shrink’s design and tattoo-related content ties into the New Perspective achievement, so pursue both storylines together.

Joy of life

Unlock Rate: 9.0% (Very Rare)

Requirement: Learn the Tabula Rasa’s lesson – Joy of Life

How to Unlock: Create Tabula Rasa via the implant treatment path in Act 2 (choosing implants over the Bold Science sacrifice), then progress his storyline once he joins the crew at the start of Act 3 to receive his lesson.

Tips: Tabula Rasa only exists on the Corporate Plug (implant) path, so this lesson is unavailable if you chose Bold Science in Act 2.

Shrewdness

Unlock Rate: 6.5% (Very Rare)

Requirement: Learn the Guard’s lesson – Shrewdness

How to Unlock: Progress the Guard Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Guard’s storyline is one of the later ones most players complete, so prioritize his interactions if you’re specifically working toward this lesson.

Integrity

Unlock Rate: 2.3% (Ultra Rare)

Requirement: Learn the Doctor’s lesson – Integrity

How to Unlock: Progress the Doctor Alter’s storyline through his available dialogue to receive his lesson.

Tips: The Doctor’s tattoo design can be obtained by speaking with the Scientist Alter, which also ties into the New Perspective achievement.

Jan Complete

Unlock Rate: 1.3% (Ultra Rare)

Requirement: Learn all the lessons from your Alters

How to Unlock: Learn all ten Alter lessons (Assertiveness, Pragmatism, Reliance, Optimism, Vulnerability, Charisma, Chill, Joy of Life, Shrewdness, and Integrity) across your playthroughs.

Tips: Since Joy of Life requires the implant path and several lessons require specific Alters to exist simultaneously, this realistically takes multiple playthroughs with careful Alter creation planning to fully complete.

Alter Storylines

Her last wish

Unlock Rate: 26.7% (Rare)

Requirement: Complete the Technician’s storyline

How to Unlock: Follow the Technician Alter’s full personal storyline through to its conclusion.

Tips: This storyline ties closely to Rapidium Ark progress, so it develops naturally if you’re building Arks regularly.

The Other Man

Unlock Rate: 18.3% (Rare)

Requirement: Complete the Botanist’s storyline

How to Unlock: Follow the Botanist Alter’s full personal storyline through to its conclusion.

Tips: The Botanist’s storyline has significant overlap with the game’s ending choices, so completing it thoughtfully affects which endings become available later.

Happy Sisyphus

Unlock Rate: 16.3% (Rare)

Requirement: Complete the Doctor’s storyline

How to Unlock: Follow the Doctor Alter’s full personal storyline through to its conclusion.

Tips: The Doctor needs to be created and kept active for his storyline beats to trigger across the playthrough.

Remaking Himself

Unlock Rate: 15.7% (Rare)

Requirement: Complete the Miner’s storyline

How to Unlock: Follow the Miner Alter’s full personal storyline through to its conclusion, including the figurine subplot involving wood and a carving tool.

Tips: This storyline does not require the implant treatment path, contrary to some assumptions, so it’s completable regardless of your Act 2 choice.

Hidden truth

Unlock Rate: 13.5% (Very Rare)

Requirement: Complete the Scientist’s storyline

How to Unlock: Follow the Scientist Alter’s full personal storyline through to its conclusion.

Tips: This can be completed without necessarily siding with Maxwell in the endgame, so don’t assume it locks you into one specific ending path.

Keeping him safe

Unlock Rate: 7.2% (Very Rare)

Requirement: Complete the Refiner’s storyline

How to Unlock: Follow the Refiner Alter’s full personal storyline through to its conclusion.

Tips: The Refiner’s storyline is tied to a specific playthrough branch, so if you’re aiming for this alongside other exclusive achievements, plan your save points around Act 2’s choice carefully.

A place in people’s hearts

Unlock Rate: 6.6% (Very Rare)

Requirement: Complete the Worker’s storyline

How to Unlock: Follow the Worker Alter’s full personal storyline through to its conclusion.

Tips: The Worker tends to have a later-appearing storyline arc, so make sure he’s active and available for dialogue throughout the later acts.

Take it easy, Dude

Unlock Rate: 5.6% (Very Rare)

Requirement: Complete the Shrink’s storyline

How to Unlock: Follow the Shrink Alter’s full personal storyline through to its conclusion.

Tips: This pairs naturally with the Chill lesson achievement, since both are tied to the same Alter’s arc.

You gotta be smart

Unlock Rate: 3.6% (Ultra Rare)

Requirement: Complete the Guard’s storyline

How to Unlock: Follow the Guard Alter’s full personal storyline through to its conclusion.

Tips: This is one of the rarer storyline completions, so prioritize the Guard’s dialogue opportunities specifically if working toward it.

Treatment Path Choices

Corporate Plug

Unlock Rate: 24.0% (Rare)

Requirement: Start treating the brain mutation using implants

How to Unlock: After receiving MRI results and speaking with Scientist Jan, call ex-wife Lena, who proposes an implant solution. Manufacture the needed implants in the workshop, then at the following kitchen meeting, select the company’s implant proposal.

Tips: This choice is mutually exclusive with Bold Science within a single playthrough. Save your game on the day of this decision so you can replay both paths without redoing the whole game.

Bold Science

Unlock Rate: 20.0% (Rare)

Requirement: Start treating the brain mutation using experimental therapy

How to Unlock: After receiving MRI results, speak with Lucas and wait for Maxwell’s call. Follow his advice, speak with the Scientist, complete the technology to hack the quantum computer, then upgrade it to create Tabula Rasa. At the following kitchen meeting, select the sacrifice Tabula Rasa plan.

Tips: This choice is mutually exclusive with Corporate Plug. Choosing this path opens up Tabula Rasa’s Joy of Life lesson and the Maxwell’s Path ending, but locks you out of the Corporate Plug and The Corporate Way achievements on the same save.

Endings

The Corporate Way

Unlock Rate: 17.6% (Rare)

Requirement: Finish the game with the help of the corporation

How to Unlock: Follow the Corporate Plug (implant) treatment path in Act 2, then complete the game through to its conclusion along that route.

Tips: This ending requires the Corporate Plug choice, so it’s incompatible with Maxwell’s Path on the same save file.

Maxwell’s Path

Unlock Rate: 11.9% (Very Rare)

Requirement: Finish the game with Maxwell’s help

How to Unlock: Choose the Bold Science (Tabula Rasa sacrifice) path in Act 2. At the start of Act 3, Maxwell will contact the protagonist; follow through with his guidance, and ensure Lena never learns the Alters exist. Whether or not you ask Lucas for help saving the Alters does not affect this achievement.

Tips: This requires the Bold Science choice, making it incompatible with The Corporate Way and Corporate Plug on the same save.

It ends in flames

Unlock Rate: 7.8% (Very Rare)

Requirement: Blow up the base

How to Unlock: In the final mission, build and install the bomb. After saying farewell to the Alters and meeting the rescue team, choose the detonation option.

Tips: This is one of several mutually exclusive final choices, so save before this decision point if you want to see other endings too.

All By Myself

Unlock Rate: 5.9% (Very Rare)

Requirement: Leave your Alters to the mercy of others

How to Unlock: After saying farewell to the Alters and meeting the rescue team, choose the do-nothing option instead of detonating the bomb or any other action.

Tips: This is one of the final choice achievements, so it’s easiest to catch by reloading a save from just before the rescue team meeting.

The things we do for love

Unlock Rate: 3.2% (Ultra Rare)

Requirement: Betray everybody as the Botanist

How to Unlock: After saying farewell to the Alters, when the Botanist Jan proposes swapping identities with the protagonist, choose the do-nothing option, allowing him to take Jan’s place as the one who swaps.

Tips: This requires having completed enough of the Botanist’s storyline for the identity-swap proposal to appear at the finale.

I deserved this more

Unlock Rate: 7.1% (Very Rare)

Requirement: Allow the Botanist to take Jan’s place at the end

How to Unlock: At the same identity-swap proposal from the Botanist, allow him to take Jan’s place. The specific option chosen at that point doesn’t change whether this achievement triggers, as long as the swap is allowed to happen.

Tips: This and The things we do for love both stem from the same Botanist proposal scene, so plan a dedicated save near the ending to catch both outcomes across separate reloads.

Special & Secret

New perspective

Unlock Rate: 2.2% (Ultra Rare)

Requirement: Get an alternative tattoo with Naranath Bhranthan

How to Unlock: Obtain the Shrink’s tattoo design (or alternatively, speak with the Scientist Alter, who can provide the Doctor’s exact tattoo design) and have the tattoo machine apply it.

Tips: Multiple Alters can be sources for tattoo designs, so if one path seems unavailable, check dialogue with other Alters like the Scientist for an alternative route to the same tattoo.

Awareness

Unlock Rate: 9.6% (Very Rare)

Requirement: Unexpected member stays with the crew

How to Unlock: Successfully get Tabula Rasa (created via the Corporate Plug implant path) to remain with your crew rather than departing.

Tips: This requires the implant treatment path in Act 2, so it’s unavailable if you chose Bold Science on that save.

A Quantum Singularity

Unlock Rate: 1.1% (Ultra Rare)

Requirement: Earn all trophies in the Alters

How to Unlock: Unlock all other 55 achievements in the game across your playthroughs.

Tips: Given the mutually exclusive endings and treatment paths, this realistically requires at least 2-3 full playthroughs with carefully planned save points at the Act 2 treatment decision and the Act 3 finale.

5-Phase 100% Completion Roadmap

Phase 1: First Playthrough (Implant Path) Play through the full story choosing Corporate Plug in Act 2, creating as many Alters as reasonably possible, and following their storylines and lessons. This unlocks most story and base-building achievements, Tabula Rasa’s Joy of Life lesson, and sets you up for The Corporate Way ending.

P2: Save Before Act 2’s Treatment Choice Before your first playthrough reaches the treatment decision in Act 2, make a dedicated manual save. This lets you replay the Bold Science path later without redoing all of Act 1.

P3: Second Playthrough (Bold Science Path) Reload your Act 2 save point and choose Bold Science instead, following Maxwell’s guidance through to Maxwell’s Path. Use this run to pick up any Alter storylines and lessons you missed on your first playthrough, along with Awareness if you didn’t get it the first time (note this ties to the implant path, so plan around that constraint).

P4: Save Before the Finale Before reaching the final farewell-and-rescue-team sequence in either playthrough, make another dedicated save. This lets you cycle through the mutually exclusive ending choices (It ends in flames, All By Myself, The things we do for love, I deserved this more) without replaying the whole game each time.

P5: Cleanup Runs Use additional short replays from your finale save point to catch every remaining ending variant, and dedicate a final full playthrough if needed to All by myselves and Not Just An Object, both of which require careful Alter creation and interaction planning across an entire run.

Conclusion

The Alters rewards planning over raw completion time. Most of its achievements come naturally from playing thoughtfully, but the treatment path choice in Act 2 and the finale’s branching options split the achievement list into mutually exclusive groups that no single playthrough can fully capture. Save deliberately at both of those decision points, and you can cover every ending and most Alter storylines across two to three focused playthroughs rather than many blind repeats.
