ATOMFALL achievement guide: All 36 Base-Game Unlocks

Plan Your Achievement Run Before Choosing an Ending

Escaping the Quarantine Zone is only part of the challenge when six different endings have achievements attached. This ATOMFALL achievement guide helps you organize exploration, combat challenges, and ending preparation so fewer tasks slip through the cracks. Use this ATOMFALL achievement guide as a base-game checklist, with particular attention to the late-game save and the separate no-telephone run described below.

The launch-era achievement list published by IGN contains 36 achievements, plus 37 PlayStation trophies when including the Platinum. The supplied, later official Atomfall Steam listing and achievement overview displays 54 achievements. This article covers the original 36; it does not cover the additional achievements in that newer total.

Player experience: Achievement Planner estimates base-game completion at 20–25 hours, rates difficulty 2/10, and reports that the easiest difficulty is sufficient. Those are one creator’s estimates, not guaranteed completion times.

A useful plan is to explore thoroughly during your main run, preserve ending options, and leave the timed escape for a run where you already know the route. Story spoilers below are limited mainly to character names, locations, and achievement requirements.

Story Progression and Robot Achievements

The Interchange milestones provide a clear progression checklist in this ATOMFALL achievement guide. Robot achievements deserve attention alongside them because, in the player video, recovered robot batteries are also used to power the Interchange.

Achievement	Unlock requirement
The Interchange	Unlock the Interchange
Reverse the Polarity	Find the Signal Redirector
Alpha	Power up Data Store Alpha
Bravo	Power up Data Store Bravo
Charlie	Power up Data Store Charlie
Delta	Power up Data Store Delta
Oberon	Gain access to the Oberon site
Unplugged	Extract the battery from an overheating robot
Batteries Not Included	Power up a deactivated robot
Any Old Iron	Completely destroy a robot

Player experience: The video describes powering all four Data Stores before gaining access to Oberon. The creator then preserved a save before entering and used it to pursue several endings.

The same creator reports earning all three robot achievements with one robot: damage it until it overheats, extract its battery, return the battery to reactivate it, and then completely destroy it.

That sequence matters. A good approach is to attempt extraction and reactivation before pursuing total destruction, keeping a save available before the encounter. The video describes targeting a fire robot’s tanks, but it does not establish a universal component checklist for every robot.

Exploration, Crafting, and Everyday Unlocks

Several achievements reward activities that fit naturally into an exploration run. The practical value of this ATOMFALL achievement guide is turning those activities into a checklist: collect useful equipment, investigate detector signals, learn skills, and keep an eye on food supplies.

Achievement	Unlock requirement	Suggested preparation
Detectorist	Pick up the metal detector	Obtain it before focusing on buried finds
Where There’s Muck There’s Brass	Find 10 metal detector caches	Investigate detector alerts while exploring
Packed Lunch	Find 5 buried lunchboxes	Track lunchboxes separately from total caches
High Tea	Consume a Cornish pasty, English tea, and a slice of cake within 30 seconds	Gather all three before starting
Burglar	Unlock 5 doors with the Signal Redirector	Watch for compatible doors after obtaining it
Make Do and Mend	Upgrade a firearm to pristine condition	Keep duplicate firearms for the upgrade method described below
Refer to Manual	Learn 12 skills	Check your learned-skill count as you spend points

Player experience: The video describes following the metal detector’s indicators to a buried cache and digging it up. Some caches contained lunchboxes. Finding ten caches therefore should not be treated as proof that you have also found five lunchboxes.

For High Tea, collect the complete meal before consuming anything. The achievement specifically calls for a Cornish pasty, English tea, and cake. A good approach is to locate all three in your inventory first so the 30-second requirement does not turn into an inventory search.

Player experience: The firearm upgrade method in the video involves learning the relevant upgrade ability and combining matching weapons to improve condition. The creator tentatively recalls finding that ability in Data Store Delta; treat that location as a lead rather than a confirmed placement.

For Refer to Manual, the target is twelve learned skills, not twelve skill points. The video notes that skills have different costs and suggests inexpensive skills as a way to reach the requirement. A good approach is to balance that count with abilities that support your remaining challenges.

Combat Challenges: Prepare Before Pulling the Trigger

The combat portion of this ATOMFALL achievement guide is about setting up the right opportunity. Several requirements depend on a particular weapon, enemy action, or group arrangement, so preparation can save repeated attempts.

Achievement	Unlock requirement	Suggested approach
Target Practice	Get 6 kills with the MK.VI Revolver without reloading	Prepare six clear shots and avoid reloading
Grand Slam	Take out at least 5 enemies in one explosion	Look for a tightly grouped cluster
Fast Bowl	Kill 10 enemies with a thrown weapon	Use thrown weapons deliberately during cleanup
Caught Red-handed	Cause an enemy to drop their Molotov cocktail	Watch an enemy preparing a Molotov
Hit for Six	Redirect a thrown grenade with the cricket bat	Have the bat ready before attempting the deflection

Revolver Kills and Explosive Groups

Player experience: For Target Practice, the creator used a room where enemies approached through a doorway, made a save, and attempted six headshot kills. Failed attempts were retried by reloading that save.

A good approach is to prioritize clear shots over speed. The requirement specifies six kills without reloading, so a missed shot can undermine an attempt using the six-round setup described in the video.

Player experience: The creator earned Grand Slam in the same general encounter by throwing a grenade at enemies clustered on a staircase. The transcript does not supply a reliable named location.

Look for a comparable grouping during play. Because the requirement is five enemies in one explosion, separate blasts do not satisfy the stated condition.

Thrown Weapons, Molotovs, and the Cricket Bat

Player experience: The video describes earning thrown-weapon kills with knives and an axe, including retrieving the axe from defeated enemies. A good approach is to use a weapon you can recover when possible, reducing the supplies needed for ten kills.

For Caught Red-handed, the creator reports shooting an enemy as it prepared a Molotov, causing it to drop. The video acknowledges uncertainty about precise timing, so this is a player-tested attempt method rather than a guaranteed timing window.

Player experience: For Hit for Six, the creator reports throwing their own grenade, quickly switching to the cricket bat, and striking it. The achievement description does not specify that an enemy must throw the grenade. Keep a save before practicing this method, since the transcript provides no exact input sequence or timing measurement.

Collectibles: Track Requirements Instead of Guessing

Use the collectible section of this ATOMFALL achievement guide during your exploration run. Notes, recipes, traders, and recordings reward careful investigation, while comics and garden gnomes benefit from a deliberate count.

Achievement	Unlock requirement
We Want Information	Read 50 notes in the Quarantine Zone
Mate’s Rates	Find 5 traders in the Quarantine Zone
Homemade	Find and learn 10 recipes
Radiophonic	Find 5 audio logs
Orna mental	Find and destroy 10 Garden Gnomes
Avid Collector	Find 10 comics

Pay attention to the verbs. We Want Information requires reading notes, Homemade requires learning recipes, and Orna mental requires destroying the gnomes you find. Merely spotting the relevant objects does not match those descriptions.

Player experience: The creator found enough notes, traders, and recipes during ordinary exploration, but needed more focused searching for gnomes and comics. Your experience may differ, so track outstanding requirements before committing to an ending.

Audio Logs and Garden Gnomes

Player experience: The video identifies a crashed helicopter, office-like areas within the Interchange, and a location near a radio tower as audio-log search leads. It supplies no coordinates or complete route.

A good approach is to revisit those leads when Radiophonic remains unfinished, checking rooms thoroughly rather than treating an entire facility as searched after one pass.

Player experience: The creator reports that the ten gnomes used for the achievement were all in the main town. That makes the town a useful focused search area, but the transcript does not identify each placement.

Comics and Hazardous Areas

Player experience: The video places one comic inside Oberon and describes needing protection against the hazardous conditions there. It mentions a crafted protective item or an upgrade associated with Dr Holder, without giving a reliable item name or complete acquisition instructions.

The actionable takeaway is to prepare protection before searching that area. Avid Collector requires ten comics; the supplied material does not establish that exactly ten comics exist throughout the game.

Ending Achievements and Your Late-Game Save

Endings are the largest portion of the original Xbox achievement score: the six character-specific escapes award 90 Gamerscore each, while the timed and no-telephone challenges award 30 each. Together, they account for 600 Gamerscore.

Achievement	Unlock requirement
Back door	Escape with Dr Garrow
Emergency Extraction	Escape with Joyce Tanner
At one with the Soil	Escape with Mother Jago
Operation Atomfall	Escape with Captain Sims
Oubliette	Escape with Dr Holder
Do you require the Operator?	Escape with the Voice on the Telephone
Quick Exit	Escape the Quarantine Zone in under 5 hours
Not Expecting a Call	Escape without answering the telephone

The ending strategy in this ATOMFALL achievement guide follows the player video’s save-reload approach. It depends on preparing character leads beforehand; a late save alone does not guarantee that every route remains available.

Player experience: The creator completed a main run, reloaded a save made after gaining access to Oberon, and pursued several alternative endings. Dr Garrow, Mother Jago, and Joyce Tanner had already been contacted. Captain Sims was handled in a separate run because that route required different preparation.

A good approach is to:

• Keep important ending characters available while investigating their leads.
• Preserve a separate save before entering Oberon.
• Confirm the relevant character’s instructions before pursuing each escape.
• Retain earlier saves as insurance against an unavailable route.

Player experience: For Dr Holder, the video points to a key somewhere in the medical area and a prisoner at the church. These are broad leads, not a complete walkthrough.

Combine the Timed Escape With the No-Phone Challenge

Player experience: The creator combined the Captain Sims ending with Quick Exit and Not Expecting a Call, reporting a run of a little over an hour.

The video emphasizes avoiding harm to unrelated townspeople and following Sims’s investigation instructions. It mentions the bakery, church, and jail but does not provide a complete decision sequence.

A good approach is to learn the route during your exploration run before attempting the timed escape. Avoid answering the telephone throughout the no-phone attempt. The creator says this challenge can accompany endings other than the telephone route; Captain Sims is the example they completed.

FAQ

Does this ATOMFALL achievement guide cover all 54 Steam achievements?

It covers the original 36 achievements listed in IGN’s launch guide. The later supplied Steam listing shows 54, and the additional achievements are outside this article’s scope.

Can you earn the base-game achievements on the easiest difficulty?

Player experience: Achievement Planner reports that the easiest difficulty is sufficient. The creator estimates completion at 20–25 hours, although exploration and retries can change your total.

Do you need six complete playthroughs for the endings?

Player experience: The creator used a prepared late-game save for several endings and a separate Captain Sims run. Character preparation matters, so do not assume every ending is available from any save.

Can Quick Exit and Not Expecting a Call be earned together?

Yes, according to the player experience in the supplied video. The creator escaped with Captain Sims in under five hours without answering the telephone, satisfying both requirements during that run.
