ATOMFALL quest list: Main Story and Oberon Checklist

How to Use This ATOMFALL Quest List

A promising lead can send you across the quarantine zone before you realize you’re missing the item that makes it useful. This ATOMFALL quest list connects the Interchange objectives so you can prepare before another trip underground. Use the ATOMFALL quest list below to follow the documented route, distinguish equipment detours from story objectives, and trace the leads toward Oberon.

Atomfall builds its mystery around information discovered through exploration, conversations, investigation, and combat. The Atomfall Steam store page describes interconnected narratives shaped by your choices, which helps explain why a straightforward mission checklist needs some context.

This guide follows player experience documented in a main-story walkthrough covering the Interchange and Oberon. Its checklist labels describe objectives; they are not presented as official quest titles. The checklist focuses on equipment collection, village investigation, bunker exploration, and the Interchange activations covered here.

Story spoilers follow, including murder-investigation details and the discovery of Oberon.

Route stage	Objective in the player walkthrough	Item or preparation involved
Starting bunker	Obtain the modified key card and leave	Modified key card
Initial Interchange visit	Restore power and reveal Oberon	Atomic batteries
Village investigation	Follow the murder leads and negotiate camp access	Evidence notes and dialogue
Bunker exploration	Recover the signal redirector	windfall key card
Additional data stores	Activate data store B and data store C	Atomic batteries
Woods exploration	Travel toward the Druids’ castle	Weapons and supplies collected along the route

Treat the sequence as a route through connected objectives. Equipment collection and conversations sit between the larger milestones because the walkthrough uses them to prepare for later areas.

Starting Equipment and Atomic Battery Locations

The opening priority is the modified key card obtained from the scientist. In the player experience shown, it opens the route out of the starting bunker and remains useful at Interchange access points.

Before heading underground, the video collects a hatchet, shotgun, metal detector, and torch from nearby locations. These pickups support combat, exploration, and scavenging, but the walkthrough does not establish all of them as mandatory story requirements.

A good approach is to collect supplies along your intended route rather than turn every equipment pickup into a separate expedition. In the supplied player experience, the narrator gathers herbs along roads and around trees.

Track Batteries Separately From Ordinary Loot

Atomic batteries are a recurring progression item in this ATOMFALL quest list. The player walkthrough collects them from traders, a body inside the Interchange, a church chest, and an outdoor machine.

Battery source shown in the video	Acquisition described as player experience	Practical consideration
Molly’s inventory	Barter for the battery or loot it after killing her	The video suggests offering Molotov cocktails when trading
Body inside the initial Interchange route	Search the body near a power machine	The walkthrough immediately uses this battery nearby
Church chest	Access the chest using the vicar’s key	The video also describes a dialogue opportunity to bargain for the battery
Machine in an outdoor pool	Reach the machine and collect its battery	Hostile fish attack when the player enters the water
Nora’s inventory	Trade for the battery or loot it after killing her	The approach to her barn contains traps

Killing traders is an option demonstrated by the video, not a requirement established for the entire game. A good approach is to examine barter options before choosing a confrontation.

Inventory preparation matters, too. The player has to make room before collecting the pool battery. A good approach is to check your carrying space before approaching the machine, since the video shows hostile fish attacking in the water.

The Interchange control rooms also contain storage terminals. According to the player experience shown, stored items can be retrieved through other terminals across the world. The walkthrough specifically reminds viewers to retrieve batteries before entering areas where they will be needed.

Collect the Nearby Exploration Tools

In the player experience, the hatchet is embedded in a fence post, while the shotgun is found on a body inside a house. The metal detector lies beside a body near the reservoir, and the torch is collected inside another house.

These are separate pickups rather than rewards for finishing the village investigation. A good approach is to distinguish equipment already collected from evidence still needed, so a missing exploration tool does not become confused with an unfinished lead.

The reservoir also contains hostile fish in the demonstrated route. A good approach is to collect the nearby items from land without entering the water unnecessarily.

Village Leads, Camp Access, and the Signal Redirector

The village section combines an investigation, an access negotiation, and optional rewards. This part of the ATOMFALL quest list explains how those activities fit into the demonstrated route without treating every conversation as a universal prerequisite.

Follow the Church Murder Evidence

In the player walkthrough, the investigation begins at the church with Macy’s body and a conversation with the vicar. The player collects the bloodied note from the body, then searches additional buildings for evidence.

The video enters a building near the hotel for another note and explores a rat-infested underground room containing a letter directing someone to kill Macy. That room also has a Molotov cocktail recipe on the wall.

The player then confronts the hardware-store owner using the evidence. Through the conversation shown, a bargain produces a crafting manual and training stimulant.

A good approach is to finish examining the evidence before confronting the shopkeeper. The demonstrated accusation refers to a letter connecting him to the murder, so reaching the shop alone is not the same as following the investigation shown.

The underground room also contains access to a barred chest in the player experience. A good approach is to handle the attacking rats before examining the surrounding loot, since the walkthrough shows them interrupting the search.

Negotiate for the Protocol Pass

The walkthrough next visits the Village Hall, reports the murder, and follows dialogue about helping Protocol and receiving something in return. The player accepts a task and obtains a Protocol pass.

In this player experience, the pass prevents immediate hostile reactions from Protocol personnel encountered on the approach to the camp. However, the video later enters a restricted Interchange approach where the player is trespassing and can still be attacked.

A good approach is to treat the pass as access assistance while continuing to watch for restricted areas.

The investigation and the access negotiation are distinct activities in the demonstrated sequence. A good approach is to track the evidence conversation separately from the agreement that awards the pass, rather than assume the shopkeeper’s reward grants camp access.

Recover the Signal Redirector

During the bunker exploration, the video collects a safe-room access key. Inside the associated rooms, the player finds a windfall key card on a body.

That card opens a crate in another bunker, providing the signal redirector, training stimulant, and first-aid supplies. The walkthrough demonstrates using the redirector on electrical devices to change the current’s direction and open access to an armory.

Village or bunker activity	Result shown in the player experience	Connection to the demonstrated route
Gather murder evidence	Evidence for confronting the hardware-store owner	Supports the investigation dialogue
Bargain with the shopkeeper	Crafting manual and training stimulant	Provides a skill-book detour
Negotiate at Village Hall	Protocol pass	Assists the camp approach
Search the bunker rooms	windfall key card	Opens the crate containing the redirector
Open the windfall crate	Signal redirector	Used on electrical devices in the armory sequence

The prison itself is not entered in the video’s main-story route. Camp armory visits provide additional weapons, but the walkthrough treats the prison interior as a separate side-quest destination.

Power the Interchange and Track Data-Store Visits

The Interchange is the central connection between these objectives. In the player experience shown, the initial visit restores power, opens previously inaccessible doors, and reveals Oberon.

Later visits continue the data-store work. The walkthrough powers data store B and data store C using additional atomic batteries.

For this ATOMFALL quest list, a good approach is to track completed power systems rather than count visits. The video enters through different regional access points, so use the terminal activations described below as your checklist milestones.

Separate Access From Power Restoration

The initial Interchange sequence uses the modified key card to open the large entrance through a control-room interaction. Farther inside, the player finds a body carrying an atomic battery and inserts it into the nearby machine.

In this player experience, that activation supplies power and allows another door to open. The player proceeds downstairs and inserts another battery into a second machine, revealing Oberon’s location.

The walkthrough also shows laser turrets and robots becoming active. A good approach is to prepare for those hazards before retracing the route out, since restoring power changes the dangers encountered inside.

Interchange task	Preparation shown in the player video	Completion cue described in the player experience
Open the large entrance	Use the modified key card in the control room	The large door opens
Restore initial power	Collect the battery from the nearby body	Power activates and additional doors become accessible
Reveal Oberon	Insert another atomic battery into the next machine	Oberon’s location is revealed
Activate data store B	Carry an atomic battery	The system activates and progress is displayed
Activate data store C	Carry another atomic battery	Another data-store system is restored

Recognize the Short Village Visit

In the player experience, the village Interchange visit is brief. The narrator opens the entrance, passes beneath a partially obstructed doorway, operates a button, and opens another door downstairs before returning outside.

That visit differs from the later battery installations. A good approach is to note the specific interaction completed rather than mark an entire Interchange area finished after entering it.

During the later camp-side visit, the player encounters spore enemies and finds an antidote recipe on a wall before descending toward a power machine. The narrator recommends searching defeated spore enemies for spores, although the enemies searched in that attempt do not supply them.

A good approach is to keep recipe discovery and ingredient collection separate on your checklist. Finding a recipe does not mean the demonstrated enemy search will produce the material you are looking for.

Equipment Detours and the Druids’ Castle Approach

The final section of this ATOMFALL quest list covers the equipment stops and woodland approach shown around the Interchange work. These activities offer additional supplies without establishing a complete ending checklist.

Examine the Training and Armory Stops

In the player experience, an upstairs trader offers a training manual and a combat-stimulant recipe. The narrator describes the manual as providing access to Firearms Mastery skills.

The walkthrough also demonstrates killing that trader and collecting items from the body, while noting that this removes access to the trader’s shop. A good approach is to examine the trade before choosing violence, especially when you still want to use that inventory.

Another armory sequence uses a key card collected within the camp. Inside the armory, the player finds an LMG, a bow, and arrows.

The separate bunker armory opened with the signal redirector contains ammunition, other supplies, and a battle rifle. A good approach is to distinguish these armory visits from data-store activations: collecting a weapon and inserting a battery are different checklist objectives.

Travel Toward the Castle

After the data-store visits, the player returns through the village and takes the road past the hotel toward the woods. The next destination in this part of the player experience is the Druids’ camp, described as a castle.

The approach includes Druids carrying bows and plants that attack the player. A good approach is to review ammunition and healing supplies before crossing the woods, using the equipment and storage opportunities already demonstrated.

At the castle entrance, the walkthrough shows the player approaching the main building and entering through a large door with a blue sign. This provides a clear destination for the woodland leg of the checklist.

Keep that arrival distinct from the earlier Interchange objectives. The batteries, evidence notes, access pass, and signal redirector each have a demonstrated use; reaching the castle is another location milestone.

FAQ

Does this ATOMFALL quest list cover every quest?

It covers the player-documented equipment stops, village investigation, bunker exploration, Interchange activations, and Druids’ castle approach described here. It does not catalog every lead, alternative ending, prison side quest, or expansion objective.

Do you have to kill traders to collect atomic batteries?

The player video demonstrates both trading and killing as acquisition methods. It explicitly describes barter options with Molly and Nora, so killing those traders is not required for their batteries in the demonstrated route.

What is the signal redirector used for?

In the player walkthrough, it redirects electrical current to open access to an armory. The player obtains it from the crate opened with the windfall key card.

What should you prepare before another Interchange visit?

Following the player experience shown, a good approach is to retrieve the atomic batteries needed for the demonstrated power-machine interactions. The walkthrough also shows hostile enemies and active defenses, so checking ammunition and healing supplies follows directly from those encounters.
