All Atomfall endings explained

Complete guide to all six Atomfall endings with detailed walkthroughs, strategic tips, and optimal choices explained

Understanding Atomfall’s Multiple Endings

Atomfall delivers a branching narrative experience where your alliances determine the fate of the Quarantine Zone. The game’s conclusion isn’t predetermined but emerges from the relationships you build and decisions you make throughout your journey.

Your primary objective involves activating The Interchange to access the mysterious Oberon meteorite beneath Windscale Plant, but the path you take and the allies you choose create dramatically different outcomes. Each character faction presents unique philosophies about how to handle the alien threat and what should become of the contaminated zone.

Strategic planning is essential since committing to one character’s questline typically locks you out of others. The game tracks your allegiance through completed missions and key decisions, so inconsistent loyalty may leave you without any viable escape options when you reach the final confrontation.

Six distinct conclusions await discovery, each tied to a specific character’s assistance. These aren’t just cosmetic variations—they fundamentally alter the future of the region and provide different perspectives on the catastrophe’s origins. Major narrative spoilers follow, so proceed with caution if you prefer to discover these endings organically.

Successfully reaching any ending requires completing that character’s entire quest chain before activating the final sequence at Oberon. Partial completion or switching allegiances mid-game often results in being stranded without evacuation options when the climax arrives.

Detailed Ending Walkthroughs

The Voice on the Telephone

This mysterious communicator offers the most straightforward path to destruction. His agenda focuses solely on eliminating the Oberon threat without extraction or preservation attempts. This approach represents the purest form of containment through annihilation.

Navigation through Windscale Plant leads to Oberon, guarded by three formidable B.A.R.D robots. The control room contains documentation revealing the site is pre-rigged for demolition—you simply need to activate four explosive charges positioned around the meteorite’s perimeter.

Pro Tip: Approach B.A.R.D robots from elevated positions and target their back canisters with grenades for efficient elimination. The explosion radius can damage nearby robots, creating chain reactions that clear the area faster.

After arming all explosives, return to the control room, activate the countdown sequence, and evacuate immediately. The subsequent phone call directs you back to your original starting bunker in Slatten Dale for a final conversation that concludes your journey.

Joyce Tanner

Tanner operates with ambiguous motives, requesting sample extraction before destruction. Her ending suggests external organizations with interests in Oberon’s properties, leaving the player questioning who they’ve truly assisted.

The sample extraction process requires significant preparation. One Atomic Battery resides in a nearby storeroom protected by a Thrall, while the second must be harvested from a B.A.R.D unit. Strategic elimination of the robot closest to the entrance prevents alerting its companions.

Advanced Strategy: Craft EMP grenades before this sequence to disable B.A.R.D robots temporarily, creating safe windows for battery extraction. Always target power cells on their backs for maximum damage efficiency.

After obtaining both batteries, install them in the power station behind control, activate the extraction sequence, collect the sample from the grinder, then trigger the destruction. The concluding meeting occurs at coordinates in Casterfell Woods where Tanner provides air evacuation.

Captain Grant Sims

Sims represents military extremism, advocating complete annihilation of the zone after evacuation. His conclusion delivers the darkest outcome, with chilling implications about protocol forces’ true intentions.

The demolition process mirrors the telephone ending, but the aftermath diverges dramatically. Post-destruction, a note at Wyndham Village Hall reveals protocol forces have consolidated at Skethermoor camp.

Travel to this location to find Sims waiting with air transport. During evacuation, he initiates ‘Operation Atomfall’—a comprehensive cleansing of the entire zone—accompanied by disturbingly casual commentary about the destruction.

Dr Alan Holder

Holder’s path involves significant narrative twists, beginning with discovering his hidden laboratory beneath St. Katherine’s Church. His questline reveals personal vendettas and contamination concerns that reshape understanding of the disaster.

The poisoning method requires precise execution. First, activate both Fire Safety System Valves flanking the dig site, then insert the contaminated Sample One into the Fluid Input mechanism left of the crater near the control room.

Common Mistake: Attempting this ending without previously completing Holder’s quest to retrieve Sample One from Medical and eliminate Dr Garrow will make this path inaccessible. Ensure full quest completion before Oberon.

Activating the system releases a green mist that neutralizes Oberon. During exit, disembodied voices express disappointment with your actions. At The Interchange, Holder announces tunnel escape routes through Medical, where he reveals shared contamination and fading psychic influences.

Dr Diane Garrow

Garrow’s route provides maximum exposition, revealing Oberon’s role in Britain’s technological advancement and the catastrophe’s true origins. This path favors knowledge acquisition over moral purity.

The extraction process resembles Joyce Tanner’s method but crucially omits the destruction phase. After securing two Atomic Batteries (using identical acquisition methods), power the drill, extract the sample, but deliberately avoid triggering explosives.

Resource Management Tip: Since this ending shares battery requirements with Tanner’s path, plan your resource gathering accordingly. Batteries don’t respawn, so wasted attempts necessitate reloading or finding alternatives.

Return to Garrow’s Robotics office where a concealed tunnel behind a painting provides escape. This conclusion preserves the quarantine but potentially advances scientific progress through the smuggled sample.

Mother Jago

Jago’s conclusion represents ultimate surrender to the alien influence. The Druids seek symbiosis with Oberon rather than escape, offering a uniquely spiritual conclusion contrasting with scientific or military solutions.

The process structurally mirrors Holder’s method but uses Growth Stimulant instead of poison. After retrieving the serum from Medical Tunnels, activate both safety valves and install the stimulant in the Fluid Input system.

Activation releases a blue mist that accelerates plant growth throughout the area. During evacuation, ethereal voices encourage communion with the soil. The finale occurs in Druid Castle caves where self-sacrifice to the pit completes the transformation cycle.

Philosophical Choice: This ending requires embracing the alien presence as a positive evolution rather than a contamination, representing the most radical perspective shift available.

Ending Comparison and Strategic Analysis

Each conclusion carries distinct moral weight and gameplay implications. Understanding these differences helps align your choices with preferred outcomes and playstyle preferences.

Moral Spectrum: The endings range from humanitarian (Voice) to extremist (Sims) with various gray areas between. Holder and Garrow involve morally questionable actions despite noble intentions, while Jago represents complete abandonment of conventional morality.

Lore Revelation Levels: Garrow’s path delivers maximum exposition about Oberon’s origins and the disaster. Holder provides personal context and contamination insights, while Voice and Sims offer minimal backstory in favor of decisive action.

Gameplay Difficulty: Tanner and Garrow require the most complex preparation with battery collection and robot combat. Voice and Sims offer relatively straightforward demolition objectives. Holder and Jago demand specific item retrieval before the finale.

Long-term Consequences: Voice creates the cleanest resolution by eliminating the threat entirely. Garrow preserves scientific potential but maintains the quarantine. Sims annihilates the zone and its inhabitants. Jago allows continued growth of the alien presence with uncertain long-term effects.

Choosing Your Perfect Ending

Selecting an optimal conclusion depends entirely on your priorities as a player. Different endings cater to varying preferences regarding narrative satisfaction, moral alignment, and gameplay challenge.

For players seeking the most positive outcome for zone inhabitants, the Voice on the telephone delivers the definitive solution. This path eliminates Oberon completely, lifts the quarantine, and exposes the dangerous research, providing closure for the affected population.

Story enthusiasts wanting maximum background revelation should pursue Dr Diane Garrow’s elaborate questline. Despite moral compromises, her route explains Oberon’s origins, the scientific ambitions, and the catastrophe’s triggering events more completely than any alternative.

Each conclusion leaves certain mysteries unresolved—Tanner’s affiliations, the telephone voice’s identity, and your character’s background remain ambiguous regardless of selection. This intentional ambiguity encourages multiple playthroughs to piece together the complete picture.

Consider your preferred gameplay style when committing to an ending path. Stealth-focused players may prefer Garrow or Holder, while combat-oriented approaches align better with Sims or Voice. Preparation-heavy players will appreciate the technical challenges of Tanner or Garrow’s battery requirements.
