The Acting Physician is one of the nastier Deviants roaming Nalcott, and it has a reputation for wasting ammo. Players kept dumping magazines into its body, watched it heal itself back up, and then got dragged into a grab. The fight only makes sense once you know that its housing is not the target.
Quick answer: Ignore the body. Wait for the glowing blue computer terminal to appear during its skill casts, destroy that, then kill the enemy normally once it stands back up.
Where the Acting Physician spawns in Once Human
This Deviant lives in medical spaces inside strongholds in the workshop area, so hospitals, medical rooms, and operating rooms are where you will run into it. Before it activates, it looks like a surgical or patient coat lying flat on the floor, with only faint static sparking around the edges. Get close and a harsh blue light fills the coat, orb lightning inflates it, and the thing stands up.
In its exposed form you can see the glowing terminal across its chest and abdomen, a medical headlamp on its head, and four mechanical tentacles spilling out from under the coat. The feet use suction cups, so it can stick itself to walls and ceilings mid-fight and drop on you from an angle you were not watching.
The nameplate above the enemy reads ACTING PSYCHICAN in game, even though it is known as the Acting Physician everywhere else. Same enemy.

The terminal is the real creature. The coat and tentacles are a shell. If you push the Acting Physician to low HP without breaking the terminal, it triggers a recovery and claws its health back, which is exactly the loop that made players ask for a nerf in the first place.
The terminal is not always available. It is only exposed while the enemy is casting certain skills, so the fight is really about waiting for those windows and hitting them hard enough to matter.
| State | What you see | What it can do |
|---|---|---|
| Disguised | Coat on the floor, faint sparks | Ambush when you approach |
| Exposed | Blue terminal on chest, four tentacles | Grab you, steal energy, recover HP |
| Terminal destroyed | Collapses, then rises on mechanical legs | No recovery, no grab |
Energy drain: eat before you fight
The Acting Physician is obsessed with your stomach, and that obsession is a real mechanic rather than flavor text. Its attacks go after your energy first, and what happens next depends entirely on how full you are.
- Hits prioritize stealing your energy instead of only chipping HP.
- A successful steal heals the Acting Physician.
- If your energy hits 0, its attacks deal massive damage.
- Getting grabbed drags you into its “surgery,” and a timely QTE struggle breaks you free.
- Keeping food on hand and topping up mid-fight is the cheapest counter to all of this.
How to kill the Acting Physician


How to tell the terminal actually broke
You get two clear signals. First, the Acting Physician drops to the ground the instant the terminal is destroyed, which does not happen from regular body damage. Second, after it stands back up it stops grabbing and stops healing itself, so its health bar only moves in one direction.
If you push it low and it suddenly recovers HP instead, the terminal is still intact. Back off, stop feeding it energy, and wait for the next cast window.
The Acting Physician nerf: what is confirmed
The complaints landed. Feedback about how punishing this enemy is has been accepted, and a nerf is being planned. No specific patch, date, or list of changes has been confirmed yet, so there is nothing concrete to plan around beyond knowing adjustments are on the way.
Until that lands, the terminal rule is the whole fight. Turn up fed, keep your distance from the tentacles, and treat every skill cast as your damage window rather than something to run from.
