| Damage | Grabs you, steals whatever item is in your hand, and stuns you. If you're caught empty-handed, that's −10 sanity instead. |
| How to counter it | Fire extinguisher spray, taser, or gun all work. You can also lure one to a Bed Monster to have it dealt with indirectly, or just keep your distance until it despawns on its own. Carrying a cheap "sacrifice" item is a community trick — if it grabs the item instead of you, you lose nothing important. |
Hiders are the one monster where item management matters as much as combat — holding literally anything (even something low-value) changes the outcome of a grab from a sanity hit to an item loss you can afford. Worth carrying a spare cheap item specifically for this reason if you're heading into a room with reported Hider activity.
The raw figure is −10 if it grabs you empty-handed. What matters is what that is a fraction of: with no class bought you start a shift on 61 sanity, and reaching zero puts you down — a teammate can revive you with a $1,000 Teddy Bear, but you cannot use one on yourself.
Worth knowing before you spend a shift carrying the wrong thing: a weapon is the answer to only 3 of the 10 threats in this game. The Hiders is answered by more than one:
One round puts a Mimic down. On a Ghost it only works once the fire extinguisher has forced it visible.
Carrying it is not a single-purpose decision — the same item also handles the Mimic and the Ghost.
The front-desk taser is the fallback when you get caught without a gun — the Mimic is slower than you, so you can reach it.
Carrying it is not a single-purpose decision — the same item also handles the Mimic and the Ghost.
The only way to make a Ghost visible. Also clears Hiders outright.
Carrying it is not a single-purpose decision — the same item also handles the Ghost.
The nine threats split into three planning problems. The Hiders is in the group that can arrive at any point — it has no shift gate and no trigger you control, so the only defence is being equipped before it happens.
The others in that bracket are the Mimic, the Bed Monster and the Stalker. Grouping them this way is more useful than a flat list, because a threat you can wait out, a threat you set off yourself and a threat that can arrive unannounced each call for a different habit — and only the last one justifies carrying gear all shift.
Every threat in the game, so you can see which ones share a counter with this one and which demand something completely different.
| Threat | Where | What it costs | Counter |
|---|---|---|---|
| 🎭 Mimic | Disguised as a patient — check-in, treatment or recovery | −15 initial, then −6 per 0.5s | 1 gun round or a taser |
| 🚪 Head Banger | Shifts 2–5, at the side check-in window | −20 sanity jumpscare if shooed without coffee | Hand it a coffee (sip twice first for +10 net) |
| 🛏️ Bed Monster | Under patient beds in Rooms 1–5 and Room 7 | −10 on the grab, then −5 every 2s | Feed it Maple Syrup, an Organ or a Transplant; stay off the red floor |
| 👤 Stalker | Hallway corners, the lobby and the surgery room | −10 sanity on eye contact | Cannot be killed — look at its legs, not its face |
| 🫥 Hiders ← this page | Camouflaged as wallpaper, in groups of 1–6 | Steals your held item and stuns you | Fire extinguisher, taser or gun |
| 👻 Ghost | Spawns after a patient dies, roams the whole hospital | −2 sanity per second nearby | Fire extinguisher to force it visible, then taser or gun |
| 👀 Mass of Eyes | Ceilings of patient rooms and the front desk, Shift 2+ | −2 to −5 sanity per 0.5s while you look up | Don't look up — or hand it Eyedrops from the window ledge |
| 📹 Camera Monster | 50% chance on a broken CCTV feed | −20 sanity jumpscare if you zoom in | Switch feeds or close the camera; repair cameras in advance |
| 🧬 Tentacle | Random 'Monster emerging' event after surgery in Room 8 | Kills the patient outright on a mistake or timeout | Scissors → Transplant → Scissors → Transplant, then 3 random steps |
| 🟢 Slimebert | Slime Shift — from around Shift 10 onward | −20 sanity on catch, then −3/s while digested | Fire extinguisher stuns; Cough Syrup blocks; no taser/gun |
3 classes start you holding something this threat responds to, which removes the scramble to find one mid-shift:
starts every run with an X-Taser — 5 charges at level 1, 6 at level 2, and a charge refunded each round at level 3.
starts with a gun — 20 rounds at level 1, 30 at level 2, plus a round back each round at level 3.
at level 3 begins each round with the backpack already full of supplies, which is how you have the consumable before you need it.
One to avoid for this specific fight: the Psychologist doubles every sanity effect in both directions. It starts you at 100% rather than 61%, but it also makes this threat cost twice what the numbers above say — a trade that only pays if you are confident you will not be touched.

Gun or Taser or Fire extinguisher. One round puts a Mimic down. On a Ghost it only works once the fire extinguisher has forced it visible. The same item also answers the Mimic and the Ghost.
