Ghost โ€” quick reference

Where you meet itSpawns after a patient dies. Floats freely through the whole hospital and goes invisible when you get close.
Damageโˆ’2 sanity per second while it's nearby (labeled in-game as "Ghostly Presence").
How to counter itSpray it with the fire extinguisher to force it visible, then taser or shoot it. Watch for doors opening on their own and stray white particles โ€” both are early warning signs before you actually see it.

How the Animal Hospital Ghost works

Because a Ghost only spawns after a patient death, the real prevention here isn't a Ghost-specific tactic โ€” it's minimizing patient deaths in the first place (correct anomaly identification, not misfiring the taser or gun on normal animals). Once one's active, the โˆ’2/second drain adds up fast if you don't hunt it down, since it follows you through multiple rooms rather than staying put.

What the Ghost costs, in sanity you actually have

The raw figure is โˆ’2 per second while it is near you. 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 โ€” a teammate can revive you with a $1,000 Teddy Bear, but you cannot use one on yourself.

  • As a drain it runs at 2 sanity a second, so a full 61-sanity bar lasts about 31 seconds of continuous exposure.
  • On a Psychologist every one of those numbers doubles โ€” that class starts at 100% sanity but takes double from everything, so this threat is exactly twice as expensive there.

What you want in your hands for the Ghost

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 Ghost is answered by more than one:

Gun

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 โ€” the same item also handles the Mimic and the Hiders.

Taser

The front-desk taser is the fallback when you get caught without a gun โ€” the Mimic is slower than you, so you can reach it.

Carrying it is not a single-purpose decision โ€” the same item also handles the Mimic and the Hiders.

Fire extinguisher

The only way to make a Ghost visible. Also clears Hiders outright.

Carrying it is not a single-purpose decision โ€” the same item also handles the Hiders.

When you can expect the Ghost

The nine threats split into three planning problems. The Ghost is in the group you set off yourself โ€” it does not roll at random โ€” a specific event brings it out, which means the counter-play starts before it exists.

The others in that bracket are the Tentacle and the Camera Monster. 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 โ€” and only the last one justifies carrying gear all shift.

The Ghost next to the other 9 threats

Every threat in the game, so you can see which ones share a counter with this one and which demand something completely different.

Does any class make the Ghost easier?

3 classes start you holding something this threat responds to, which removes the scramble to find one mid-shift:

  • Security

    starts every run with an X-Taser โ€” 5 charges at level 1, 6 at level 2, and a charge refunded each round at level 3.

  • Secret Agent

    starts with a gun โ€” 20 rounds at level 1, 30 at level 2, plus a round back each round at level 3.

  • Head Nurse

    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 โ€” a trade that only pays if you are confident you will not be touched.
