How to Spot Anomalies
Compare → decide → act. A checklist of the verified signs, what to compare each one against, and the safest action.
Quick answer
Check the patient at the window in three layers: appearance (face, eyes, posture), photo (does it match, is it static), behavior (voice, staring, movement). Any clear sign is enough to reject. One weak sign is not proof — compare more before you act.
Signs you can see by eye
| Sign | What to compare | Action |
|---|---|---|
| Smiling face with big eyes, dark pupils and drawn-on smile | Real face is gone; tasing removes the smile | Reject (clear sign) |
| Three glowing red eyes | Eyes look off-center; original eyes may still peek through | Reject (clear sign) |
| Crooked, distorted smile with sharp teeth and mismatched high eyes | Eyeballs stay visible even if the smile changes | Reject (clear sign) |
| X-ray-style face: small wide circular eyes with realistic teeth | Face turns normal when the expression changes | Watch and compare |
| Staring at you through the window, head turning up to ~60° | Ratthew also stares and is NOT an anomaly | Compare with other layers |
| Hollow dark eyes, twitching, hunched posture | Hollow Face — will do a Death Ritual during recovery | Reject; if already in, stay in the room with it |
| Twitching in arms/head/neck, hunched back | May only show on cameras; may also walk out calmly | Check cameras before deciding |
| Extremely small patient, high-pitched voice (pink bunny, three red eyes) | Tiny Anomaly — hostile once checked in | Reject (clear sign) |
Signs you only see on the photo
| Sign | What to compare | Action |
|---|---|---|
| Photo does not match the patient (face, ears, ear color) | Compare photo to the patient at the window | Reject (clear sign) |
| Static, grainy photo | Before shift 10 a static photo is a strong sign; after shift 10 it is not guaranteed | Reject early, or close the shutters instead of tasing |
| Cursed photo that gets picked up too early | Costs 10 sanity | Let photos finish developing before inspecting |
What about the camera?
Some signs — staring and twitching in particular — can appear only through the security cameras, including when a Mimic is disguised as an anomaly or a normal patient. When in doubt, take a photo and watch the patient's movement between rooms before reacting.
Common mistakes
- Tasing a normal patient to 'test' — costs 15 sanity and skips their treatment.
- Treating fire as an anomaly sign — burning and critical patients still need treatment first.
- Trusting a rumour over a sign you can compare — if the clue is unverified, do not rely on it alone.
- Shooting a static-photo patient after shift 10 — they faint, which shows they are a normal patient, but you lose the shift-peace instead of closing the shutters.
