Help for the patient in front of you

Use the checker during an examination, or open the exact-night walkthrough when the task prompt, patient count, or leave sequence is holding you up.

Interactive

Anomaly checker

Record form, heart-rate, approximate temperature, night-vision, face, hallucination, and sanity observations without receiving a guessed verdict.

Night 1

First-shift walkthrough

Complete the 10-patient loop, troubleshoot treatment prompts, and leave after the observed 12am-to-6am shift.

Night 2

Second-shift walkthrough

Follow the observed 12-patient target, changed prompts, faceless warning, and limited completion note.

Night 3

UPD3 walkthrough

Use the new badge-backed guide while exact Night 3 patient counts and endings remain held.

Night Shift Protocol

Cross-check before the form decision

The protocol gives warning categories rather than an exact automatic rule. Keep objective evidence separate from frightening visuals.

Current gameplay shows a patient form with photo, name, age, and injury; heart-rate and temperature tools; night vision; hallucination warnings; and a visible sanity meter. Temperature guidance is around 37°C, but exact heart-rate ranges, temperature intervals, and sanity formulas are not confirmed.

Read the beginner guide
1. Identity and form consistencyCompare the patient with the photo, name, age, and injury before submitting.2. Heart-rate checkTreat an abnormal reading as a warning and combine it with other evidence.3. Temperature checkCompare the reading with the approximate 37°C expectation.4. Night-vision checkLook for presences that normal lighting does not reveal.
Current game snapshot

UPD3, three completion milestones

The July 27 check shows the experience as [UPD 3] Night At The Infirmary (Anomaly), with Welcome, Completed Night 1, Completed Night 2, and Completed Night 3 badges.

The official description places you on a night shift examining patients who may not be what they seem. It warns about flashing lights and jumpscares and suggests headphones and high graphics. Roblox data now shows a July 26 UTC update timestamp. Public code pages now mention UPD3, UPD2, classes, traits, and Shards, but no creator-written class roster, complete UPD3 patch list, or exact Night 3 patient count was public in this run.
