Night At The Infirmary Ending Guide

Night At The Infirmary by A.D. Games is still in UPD 1 beta, and its endings are unlocked by surviving multiple night shifts while making consistent decisions at the reception window. Unlike a linear story game, outcomes appear to track how accurately you filter anomalies, how many nights you clear, and whether you follow specific behavioral patterns across shifts. This guide documents what the community has found so far without spoiling cutscene dialogue or late-night story beats.

We organize every requirement as confirmed (reproduced by multiple players on the current build) or reported (plausible but not yet widely verified). Beta patches can change triggers overnight — bookmark UPD 1 patch notes and revisit this page after major updates. If you have not finished the core loop yet, start with the first night walkthrough and the all nights guide before chasing endings.

This page is spoiler-light by design. Section headings tell you what affects outcomes; detailed story text stays vague so you can skim requirements first and discover narrative payoffs in-game.

Confirmed (UPD 1): Ending sequences do not appear on night one. Players must progress through multiple shifts using the standard three-layer inspection loop — window, photo print, and CCTV — described in our how to play guide. Dying mid-shift or restarting from night one resets the current run's progression toward endings.

Confirmed (UPD 1): Reaching later nights is a baseline gate. The all nights walkthrough explains escalation patterns; most documented ending attempts begin after players can reliably survive without skipping inspection layers.

Reported (community): Some players describe a branching prompt or environmental change on the final shift of a run, triggered only if earlier nights met hidden accuracy thresholds. This has not been datamined or officially confirmed — treat it as a hypothesis until more players replicate it on the same build version.

Reported (community): A few threads suggest endings may require surviving a specific night count (often cited as night five or later) with no incorrect admits. Night counts vary between reports because beta difficulty tuning changes how fast anomalies appear. Use the anomaly checklist tool to stabilize accuracy rather than chasing a single night number.

Not every click affects endings, but several decision types recur in community route notes. Understanding them helps you plan a run without spoiling what happens when a route succeeds or fails.

• Anomaly filtering accuracy — Confirmed: Admitting a confirmed anomaly ends the shift and typically resets ending progress for that run. Rejecting genuine human patients carries penalties that may influence which ending pool you qualify for. See how to reject patients for timing guidance.
• Three-layer discipline — Confirmed: Skipping the photo or CCTV step does not unlock alternate endings; it increases mistake rate. Ending hunters should complete every layer even when the window check feels obvious.
• Patience under pressure — Reported: Late-night queue pressure and audio distractions may push players toward hasty approvals. Several "good ending" attempts emphasize slow, repeatable routing between stations on the infirmary map.
• Consistency across nights — Reported: Mixed strategies (aggressive rejecting one night, permissive admitting the next) correlate with neutral or bad outcomes in player logs, though sample sizes are small.
• Special patient handling — Reported: A subset of anomaly types may need to be rejected in a particular order or before a certain night to stay on a "clean" route. Document your own runs if you test this — beta patches shuffle spawn tables.

None of the reported choice flags are mandatory reading for casual play. They matter most when you are deliberately attempting a second ending after finishing a standard survival route.

Beta builds currently describe a small set of outcome categories. Names below are community labels, not official in-game titles.

Standard Survival Ending

Confirmed: Clearing the final shift of a multi-night run without dying triggers a closing sequence for many players. This is the default "you survived the infirmary" outcome — lower stakes narration, no special prerequisites beyond making it to the last documented night on your build.

High-Accuracy / "Good" Ending

Reported: Players with near-perfect anomaly detection across all layers sometimes describe an alternate closing monologue or environmental detail (extra dialogue, different lighting, or an additional clipboard entry). Requirements commonly cited: zero incorrect admits, minimal wrong rejects, and consistent three-layer checks. Replicate with the detection guide open beside you.

Failure and Bad Endings

Confirmed: Admitting a lethal anomaly mid-shift ends the night immediately — this is the most common bad outcome and does not require a separate route. Reported: Repeated wrong rejects of human patients may lock players into a punitive ending variant with darker epilogue text. Track your mistakes per run if you are testing this branch.

Hidden / Alternate Route

Reported: Fragments of a secret ending circulate in Discord and forum threads: specific anomaly rejects on consecutive nights, then a unique patient on the final shift. Evidence is mixed; no video proof has been verified across multiple UPD 1 builds at the time of writing. Label your own findings reported until three or more independent players match the steps.

Return to the walkthrough hub for shift-by-shift help while you test each route.

Use this checklist when deliberately hunting endings rather than playing casually.

1. Stabilize early nights — Repeat the first night walkthrough until the inspection order is muscle memory.
2. Log accuracy — Note every admit, reject, and layer skipped. Ending requirements hinge on mistake counts more than speed.
3. Read tells reference-first — Keep visual, photo, and camera tells tabs ready; ending routes tolerate zero lazy approvals.
4. Pick one hypothesis per run — Test a single reported requirement set per playthrough. Changing tactics mid-run confounds results.
5. Watch patch notes — After each UPD 1 update, assume reported routes are stale until reconfirmed.

Most players will see the standard survival ending on their first full clear. Treat good and hidden routes as long-term goals — the horror loop in how to survive remains the same regardless of which epilogue you earn.

A.D. Games has not published an official ending flowchart for UPD 1. Everything on this page is compiled from player reports, wiki playtests, and repeatable experiments on public beta servers. Ending triggers, night counts, and dialogue can change without notice.

When a requirement moves from reported to confirmed, we update this guide in place. If you discover a reproducible step on the latest build, compare your run recording against the UPD 1 notes version date before submitting feedback. Until then, enjoy the uncertainty — beta horror is meant to be learned, not fully solved on day one.
