Enemies

Updated:

Every hostile entity that can spawn during a shift — what it looks like, how it attacks, and the counter that ends the encounter.

Not Every Enemy Fights Back

The enemies catalogue covers everything that can spawn on the hospital floor during a shift, but they don't all behave the same way. Roughly three quarters of the entries are passive threats — they damage you only if you engage with them incorrectly (looking at Stalker, staring at Mass of Eyes, walking into Slime). Treat them as environmental hazards. The rest — Skinwalker most importantly — are active hostiles that pursue patients or staff. Counter selection depends entirely on which category you're dealing with.

What to Carry vs Which Enemy

| Enemy | Counter | Sourced From | |---|---|---| | Skinwalker | Gun, Taser, or Fire Extinguisher | Destructoid | | Bed Monster | Maple Syrup (approach with) | Destructoid | | Head Banger / Wall Bangers | Coffee OR food | Destructoid | | Slime | Mop (hold E) | Destructoid | | Surgery Tendril | Finish the surgery minigame — don't shoot it | Destructoid | | Mass of Eyes / Ceiling Monster | Keep camera angled down | Destructoid | | Stalker | Avoid direct eye contact | Destructoid | | Hiders | Fire Extinguisher or Taser, then break line-of-sight | community |

If you're loading inventory before a shift, treat Maple Syrup + Coffee + Fire Extinguisher as the universal three-slot starter — they cover the most common encounters without overlap.

The Sanity-Drain vs Physical-Damage Split

Sanity-drain enemies (Mass of Eyes, Stalker, Camera Figure, Shadow Figure) hurt you indirectly — through prolonged observation. They're almost always survivable if you can break visual contact. Physical-damage enemies (Skinwalker, Hiders) require an actual item or escape route. Decide which category you're in before reaching for the inventory bar; a Gun does nothing against Mass of Eyes.

Skinwalker Is Where Most Runs End

If your run collapses, it's almost always because of a Skinwalker — either one that converted from a missed anomaly at intake, or one that caught you mid-treatment. Three counters work (Gun, Taser, Fire Extinguisher) but they're not interchangeable: Gun has range, Taser has reuse, Fire Extinguisher has the most uses per refill. If a Skinwalker grabs you, mash E to break the pin — don't try to wait it out.

FAQ

What's the difference between an enemy and an event? Enemies persist until countered or avoided. Events have timers and resolve one way or the other when the clock hits zero. Monster Emerging is both — it's an event that spawns an enemy.

Why are Tendril and Tentacle separate entries? Tendril is the Room 8 surgery failure state (purple vines smother the patient when the timer ends). Tentacle is the earlier pressure indicator inside the same room. Same family of mechanic, different game states.

Do enemies follow me between rooms? Most don't. Hiders briefly chase. Skinwalker actively pursues. Stationary spawns (Bed Monster, Tendril) anchor to their room.

Which enemies should I memorise first? Skinwalker counters, Bed Monster's Maple Syrup bribe, and the "don't look up" rule for ceiling threats. Those three patterns cover most early-shift deaths.
