The deer who hired you runs your tutorial, grades your shifts — and carries the same TOP SECRET briefcase as everyone else tangled in the Animal Corp story. The July 10 update is literally named after him.

"Your sanity is important. Don't DIE on me."
The list above is the order. This is what it means at the window — because two of those three unlocks decide what you are even capable of seeing.
| Unlock | What you can do afterwards that you could not before |
|---|---|
| Shutters after Shift 1 | Refuse a patient at the window. This is the cheapest tool in the game — it costs no sanity, no ammunition and no shift score, and it stays the right answer any time you are unsure. |
| CCTV after Shift 1 | See the 8 of the 19 anomalies that are invisible any other way. Until this unlock you are not missing them through carelessness — you physically cannot detect them. |
| Shop + Rooms 6–8 after Shift 2 | Buy supplies at all, and take more patients per shift — the cap on patients is the number of rooms you have open. Room 8 is also where the Tentacle surgery event can trigger, so the unlock brings a threat with it. |
| Taser after Shift 3 | Your first weapon — and the answer to three of the nine threats. Tasing a confirmed anomaly is +2 sanity; tasing a normal animal by mistake is −15, which is why it arrives after the identification tools rather than before. |
Read in order, the sequence is deliberate: refuse, then see, then act. You spend your first two shifts with no weapon at all, which is not a handicap — it is the game teaching you that shutting the window is the move that never backfires.
Harlow appears from Shift 1 and grades you at the end of each shift through Shift 7, then disappears from the run. Nothing further unlocks after that — by the time he leaves you already have every tool the tutorial hands out, and Shifts 8 onward are the same hospital with a rising threat count rather than new equipment.
One honest gap: the grade he gives at the end of a shift is visible, but the formula behind it is not documented anywhere we could verify — not in the community wiki, not in patch notes. Anyone telling you exactly how the score is calculated is guessing. What is confirmed is what feeds into a bad run rather than a bad grade: animal deaths, of which three end the run.
The community theory: Harlow knows exactly what's infecting the patients and keeps hiring anyway. The game confirms none of it — we label theories as theories.
The update named after him shipped a new Dr. Harlow model and new Harlow interactions. What those interactions contain — and whether they advance the Animal Corp story — is still being documented by the community; we're tracking it on the updates page and will expand this section as details are verified.
Everything below is the character record: appearance, story role, what he or she knows, and where the open questions still sit — kept separate from the walkthrough above.
| Species | Light-orange muntjac deer — blue scrubs, white coat, head mirror |
|---|---|
| Role in the story | Hired you; grades every shift and unlocks your tools (Shifts 1–7) |
| Carries | A black suitcase stamped TOP SECRET in red |
| Catchphrase | “Your sanity is important. Don't DIE on me.” |
A light-orange muntjac deer in blue scrubs, white coat, stethoscope, and head mirror. Dr. Harlow hired you, appears every shift to grade your performance, and progressively unlocks the tools you need to survive: shutters and cameras after Shift 1, the shop and emergency rooms after Shift 2, the taser after Shift 3.
His catchphrase — "Your sanity is important. Don't DIE on me" — is the closest thing to warmth he shows. On paper, he's just a competent, slightly detached boss.
He carries a black suitcase stamped TOP SECRETin red — the same marking that shows up on Ron from Accounting's briefcase, and again inside the safe Ratthew leads you to in Room 5. Three separate people, three matching briefcases, zero explanation.
Through a lobby-window glitch, players have spotted an anomaly version of Harlow— hollow eyes, blank expression — staring back in. He's also been seen stepping outside to talk with someone in a hazmat suit before returning to work like nothing happened.
None of this is treated as suspicious in-game. He keeps grading your shifts, keeps handing out gear, keeps saying the same lines. If he knows what's happening at Animal Corp, the game gives him zero visible reaction to it.
The July 10, 2026 update — literally named after him — gave Harlow a new model and new interactions. Naming a major content drop after the most quietly suspicious character in the game, without resolving any of the suspicion, reads either as a coincidence or a very deliberate tease. The community leans toward the latter.
Dr. Harlow has never been said to work for the Corporation. The link is an object — and an object is the weakest kind of evidence and the hardest to explain away, which is exactly why this one keeps coming up.
| Character | Link | What the game actually shows |
|---|---|---|
| 🐈 Liz | Worked for the Corporation | Worked for Animal Corp's news channel and was fired for telling the truth about the infection. |
| 🐁 Rattina | Worked for the Corporation | Worked for the Corporation, then vanished before the game begins. Her photo is filed in the Room 5 safe. |
| 🐭 Ratthew | Connected by family | No link of his own — his twin sister Rattina is the connection, and finding her is what his whole storyline is about. |
| 🦌 Dr. Harlow ← this page | Carries Corporation material | Carries a black suitcase stamped TOP SECRET in red — the same object that turns up in the Room 5 safe. |
| 🐰 Barney | No documented link | Nothing ties him to the Corporation. What he proves is separate and arguably worse: the screening scanner reads him green across all five visits. |
| 🦆 Officer Duckman | No documented link | The only character doing ordinary work for an ordinary reason. He is not investigating the Corporation — he is looking for one specific criminal. |
One object shows up three separate times, and it is the same object each time: a black suitcase stamped TOP SECRET in red. It is never opened on screen.
Three carriers, no contents. Treat any account of what is inside as invention — the game has not shown it, and neither have we.
Sorted by what each of them does with what they have, the cast falls into four positions — and Dr. Harlow is in the one labelled knows and does not say. Barney occupies the same position. The two who withhold are the two you spend the most time with, which is most of why the game feels the way it does.
| Character | What they know | What they do with it |
|---|---|---|
| 🐈 Liz Knows and tells you | That the infection is real, and that Animal Corp buried the story. | Tells you, and hands you a camera so you can gather the proof she was fired for trying to publish. |
| 🐭 Ratthew Knows and tells you | That a government is hunting him for what he uncovered, and that his sister disappeared into the same organisation. | Warns you to trust nobody in the building, then leaves you the key rather than the answer. |
| 🐁 Rattina Knew, and is gone | Unknown — whatever it was, it was worth disappearing over. | Nothing. She is gone before the game starts, and the only thing she leaves is a photograph in someone else's safe. |
| 🦌 Dr. Harlow Knows and does not say | Unclear, and that is the point. He carries Corporation material and has been seen outside the hospital talking to an animal in a hazmat suit. | Runs your tutorial, grades your shifts, and explains none of it. |
| 🐰 Barney Knows and does not say | What he is. He is the only character who knows he is an anomaly and behaves accordingly. | Asks you for coffee, a scalpel, and finally to hide him — never once explaining why any of it is necessary. |
| 🦆 Officer Duckman Does not know | Less than you do, by the time he arrives. He has a photograph and a name. | Asks his questions and acts on your answer — which is why the choice lands on you rather than him. |

View the Timeline →Dr. Harlow is your boss — an orange muntjac deer in blue scrubs who appears at the start of your run, unlocks core features after each early shift (shutters and cameras, then the shop and ER, then the taser), and grades your performance at the end of every shift.
Unconfirmed. An anomaly version of Harlow with hollow eyes can be glimpsed at the lobby window through an easter egg, and he's been seen talking to an animal in a hazmat suit outside the hospital — the community suspects he knows more than he says, but the game hasn't confirmed anything.
Three things, in this order: shutters and the CCTV system after Shift 1, the shop and emergency Rooms 6–8 after Shift 2, and the taser after Shift 3. Nothing unlocks after that — he keeps grading you through Shift 7 and then stops appearing entirely.
Because what does Dr. Harlow unlock first tells you how the game wants you to play: refuse, then see, then act. Shutting the window costs nothing and can never be wrong, CCTV is the only way to detect 8 of the 19 anomalies, and only once you can identify a target does he hand you something that costs −15 sanity to use on the wrong animal.
No. He appears from Shift 1 and leaves after Shift 7, taking the tutorial and the end-of-shift grade with him. Everything from Shift 8 on runs on the tools you already have.
Harlow's Favorite Update — named after him — shipped a new Dr. Harlow model and new interactions with him. The full content of the new interactions is still being documented.
Unconfirmed. An anomaly version of him — hollow-eyed, blank expression — has been glimpsed through a lobby-window glitch, and he's been seen talking to someone in a hazmat suit outside the hospital. The game hasn't confirmed anything either way.
He carries the same TOP SECRET briefcase as Ron from Accounting and the one hidden in the Room 5 safe — three separate storylines all pointing at the same unexplained secret.
