Finding all anomalies in Buenos Aires Mirror Line means successfully identifying over 90 unique paranormal events classified into four distinct types: Displacements, Intrusions, Auditory shifts, and the deadly Mimics. This guide provides a complete, location-by-location checklist to ensure you can spot every discrepancy, maintain reality's integrity, and survive your shift.
Your primary tool is your observation log. When you spot an anomaly, you must correctly identify its location and type from your terminal to resolve it. Misidentifying an anomaly or, worse, failing to spot one, will cause the timeline's stability to degrade, eventually leading to a run-ending collapse.
What Are the Main Anomaly Types?
Success hinges on understanding the four categories of paranormal phenomena. While some are subtle and harmless, others are aggressive and can end your run instantly if not reported. The game's difficulty scales with how many of these types can manifest simultaneously.
- Displacement Anomalies (Subtle Changes): These are the most common but often the hardest to spot. A Displacement is any alteration to an existing object in the environment. This can be an object moving, disappearing entirely, changing color or material, or an alteration to a detail, like a painting's subject suddenly smiling.
- Intrusion Anomalies (Unwelcome Guests): An Intrusion is the appearance of something new that wasn't there before. These range from innocuous new objects (a misplaced book) to terrifying apparitions (a shadowy figure in a corner). Intrusions are generally more dangerous to timeline stability than Displacements.
- Auditory Anomalies (Things That Go Bump): These are sound-based events with no visible source. You might hear footsteps in an empty hall, a distant, untraceable phone ringing, or distorted whispers. Wearing headphones is critical, as these are easy to miss but still degrade stability.
- Mimic Anomalies (The Most Dangerous): The rarest and most lethal category. A Mimic is an entity that replaces a mundane object and attacks if you fail to report it in time. The familiar armchair in the corner might suddenly sprout an eye or a hand. Reporting these is your absolute highest priority.
Location 1: The Recoleta Apartment
Your first assignment is a seemingly normal apartment in the historic Recoleta neighborhood. Its tight, cramped layout makes it a breeding ground for subtle Displacement anomalies. Your primary challenge here is visual noise; learn to memorize the placement of every book, frame, and piece of furniture.
Key focus areas: The cluttered bookshelves, the hallway mirror, the portrait of the woman, and the rotary telephone.
Here is a checklist of all known anomalies for this map:
| Anomaly Name | Type | Description | Threat Level |
|---|---|---|---|
| Weeping Portrait | Displacement | The woman in the large portrait in the living room appears to cry tears of black ink. | Medium |
| Shifting Books | Displacement | Books on the main shelf have changed order, color, or disappeared entirely. | Low |
| Hallway Mirror | Displacement | Your reflection in the hallway mirror is distorted, absent, or delayed. | Medium |
| Open/Closed Door | Displacement | A door that was previously closed is now open, or vice versa. Usually the bedroom. | Low |
| Flickering Lamp | Displacement | The desk lamp flickers erratically or changes color. | Low |
| Wrong Time | Displacement | The time on the analog clock is wildly incorrect or the hands are spinning. | Low |
| The Man in the Hall | Intrusion | A tall, slender, featureless dark figure stands at the far end of the hallway. Vanishes if stared at. | High |
| Extra Painting | Intrusion | A new, often disturbing, painting has appeared on a wall. | Medium |

Location 2: The Subte Station
The abandoned Line H Subte (subway) station is a significant step up in difficulty. The large, open spaces and long sightlines mean anomalies can be harder to spot at a distance. This level introduces more aggressive and visually jarring Intrusions. Auditory cues are paramount here, as the natural echo of the station can mask paranormal sounds.
Key focus areas: The vending machine, the far end of the tunnels, the ticketing booths, and the advertisements on the walls.
| Anomaly Name | Type | Description | Threat Level |
|---|---|---|---|
| Shifting Tiles | Displacement | A pattern on the floor tiles has changed, or a single tile is a completely different color. | Low |
| Ad Poster Change | Displacement | The advertisement posters on the walls have changed to show different products or unsettling imagery. | Medium |
| Vending Machine Lights | Displacement | The lights inside the vending machine have changed color or are off when they should be on. | Low |
| Ghost Train | Auditory/Intrusion | The sound of a train arriving at the platform, but no train appears. Sometimes a faint light is seen. | Medium |
| The Platform Wanderer | Intrusion | A semi-translucent figure paces back and forth on the opposite platform. | High |
| Vending Machine Face | Intrusion | A distorted human face is pressed against the inside of the vending machine glass. | High |
| New Exit Sign | Intrusion | A new, glowing exit sign appears, pointing towards a solid wall. | Medium |
| Tunnel Screech | Auditory | A loud, metallic screeching sound echoes from deep within one of the tunnels. | Medium |
| Ticket Booth Knocker | Auditory | A sharp knocking sound comes from inside the abandoned, locked ticket booth. | Low |
| The Watcher | Intrusion | A humanoid figure with glowing eyes is briefly visible at the far end of the tunnel. | High |
| Puddle Reflection | Displacement | The reflection in a puddle on the ground shows the ceiling, but with a hanging body. | Medium |
| Bench Mimic | Mimic | A section of a metal bench briefly contorts into a metallic, jaw-like shape. | Critical |

Location 3: The Palermo Art Gallery
The final location is a sterile, minimalist art gallery in Palermo. The lack of clutter makes changes seem obvious, but the game uses this to its advantage with abstract and surreal anomalies that can blend in with the art. This level is the ultimate test of your memory and sanity, featuring the highest concentration of high-threat Intrusions and Mimics.
Key focus areas: The central marble sculpture, the mannequin exhibit, the 'Empty Room' installation, and the video art screen.
| Anomaly Name | Type | Description | Threat Level |
|---|---|---|---|
| Bleeding Sculpture | Displacement | The central white marble sculpture appears to be "bleeding" a thick, dark red or black substance. | High |
| Mannequin Migration | Intrusion | The art mannequins have changed their poses or moved to entirely different locations in the gallery. | Medium |
| Wrong Exhibit Name | Displacement | The small plaque next to a piece of art has a different title or artist name. | Low |
| Whispering Exhibit | Auditory | Faint, overlapping whispers can be heard emanating from the 'Empty Room' installation. | Medium |
| The Gallery Patron | Intrusion | A shadowy figure dressed in a trench coat and hat can be seen observing a painting, vanishing when approached. | High |
| The Red Door | Intrusion | A stark, red door has appeared on a previously blank white wall. | Medium |
| Glitching Video Art | Displacement | The video loop on the screen freezes, corrupts, or shows unsettling imagery not part of the original piece. | Medium |
| Footsteps on Marble | Auditory | The clear, sharp sound of footsteps on the marble floor with no visible source. | Low |
| The Follower | Intrusion | A piece of 'kinetic' art, a floating sphere, detaches from its installation and slowly follows you. | High |
| Painted Smile | Displacement | A figure in a painted portrait now has a wide, unnatural smile. | Medium |
| Living Paint | Mimic | A splotch of paint on a canvas writhes and extends a tendril towards the viewer. | Critical |
| Pedestal Mimic | Mimic | The white pedestal for a sculpture briefly opens like a mouth filled with teeth. | Critical |
Tips for a Perfect Anomaly-Hunting Run
Simply knowing the anomalies isn't enough. You need a strategy to spot them efficiently under pressure. A perfect, no-miss run is possible if you follow a strict methodology.

Establish a Mental Baseline
When the level begins, don't just start cycling through cameras. Spend the first 60-90 seconds taking a mental snapshot of everything. Go through each room and consciously note the state of key objects: the position of the clock's hands, the number of books on a shelf, the exact pose of a mannequin. Your memory is your most important weapon.
The "Blink" Method
Anomalies often manifest when you're not looking. You can force this. Stare at one camera for 5-10 seconds, then quickly switch to another camera and immediately back to the first. This rapid "blink" will often make a new change pop out at you, as your short-term memory of the scene just seconds prior will still be fresh.
Sound is Half the Battle
Play with good headphones. This is not optional. Auditory anomalies are the easiest to miss and will silently tank your stability rating. Listen for anything that breaks the ambient noise of the location—a whisper, a footstep, a knock. These are free points if you're paying attention.
Prioritize Your Reporting
Not all anomalies are created equal. A flickering light is a minor issue; a Mimic is a run-ending catastrophe. If you spot multiple anomalies at once, always report the Mimic or high-threat Intrusion first. These degrade stability fastest and can trigger a game over on their own. A simple Displacement can wait a few extra seconds.
Frequently Asked Questions (FAQ)
How many anomalies are there in total in Buenos Aires Mirror Line? There are over 90 documented anomalies across the three main locations. Each run randomizes which ones appear, so you won't see all of them in a single playthrough.
What happens if you miss an anomaly? Missing an anomaly causes the timeline stability to decrease. If stability drops to zero, reality collapses and your run ends. Certain high-threat anomalies, especially Mimics, can cause an instant game over if not reported quickly.
Is there a "true ending" for finding all anomalies? While there isn't a special cutscene for a single perfect run, achieving a high completion percentage across multiple runs contributes to unlocking diary entries and lore fragments that piece together the game's overarching narrative.
Which anomaly is the hardest to spot? Generally, the most difficult are subtle Displacements in cluttered areas, like a single book changing color on a packed shelf in the Recoleta Apartment. Auditory anomalies without clear directional cues are also frequently missed by new players.
Final Take
Buenos Aires Mirror Line is a game of inches and seconds. It rewards methodical, almost obsessive, attention to detail. The true horror isn't in the jump scares, but in the slow-creeping doubt that makes you question your own memory. With this checklist, you can turn that doubt into a weapon, transforming from the hunted into the expert paranormal investigator the job requires.
