Enemy

Hiders

Updated:

Flat humanoid shapes that peel off the walls, dash at the player, and steal inventory items.

Overview

Hiders are the corridor-spawned ambush enemy that pretends to be wall art. Their bodies colour-match whatever wall they spawn on, so what you actually see is a grin and a pair of eyes hovering over a faint outline. The grin is the giveaway — once you train your eye for it, you spot them before they ever activate.

They arrive in groups of 1 to 6 per zone and stay completely still until you close the gap while looking directly at one. That's the activation trigger. The Hider drops off the wall, its body turns solid black, the heavy-breathing audio kicks in, and it chases for 5 to 6 seconds before evaporating. A successful melee tag drains sanity and frequently steals a Treatment item right out of your hand, which can blow up a downstream patient encounter if you were carrying the wrong thing at the wrong time.

Key Mechanics

Spawn in groups of 1–6 in patient rooms or hallways. Stay stationary while viewed from distance. If a player closes the gap while looking directly at one, it drops off the wall, its body turns black, and it chases for 5–6 seconds before evaporating. Heavy-breathing audio cue plays on approach. A successful contact drains sanity and often steals a Treatment item from the player's hand.

Pros & Cons

Pros

  • ✓ Telegraphed by a clear visual tell (the grin and eye-pair) before activation, so disciplined wall-scanning prevents most encounters
  • ✓ Self-resolves: if you survive the 5–6 second chase, the Hider evaporates and the encounter ends
  • ✓ Can be killed cleanly with three different weapons (Fire Extinguisher, Taser, Gun) — broad counter coverage

Cons

  • ✗ Spawns in groups of up to 6 per zone, multiplying both the spotting workload and the chase risk
  • ✗ Steals Treatment items on contact — losing a key item mid-shift can cascade into patient deaths
  • ✗ X-Ray room has a known overlap bug where two Hiders can spawn on top of each other, doubling the chase pressure

How to Handle

Hold a wider corridor scan than you would for any other enemy. Hiders camouflage to wall colour but their grins and eyes stay visible — sweep your camera across each wall surface before moving deeper into a hallway. Mark the spots mentally; you don't need to engage every Hider, you just need to know where they are so you don't accidentally activate one.

If engagement is required: equip Fire Extinguisher, Taser, or Gun (in roughly that order of resource efficiency) before approaching. All three work on both dormant and chasing Hiders. A single shot or a single extinguisher burst takes one down.

If you accidentally activate one and you're unarmed, sprint. The chase window is only 5–6 seconds and breaks fully on line-of-sight loss around a corner. Don't try to outrun in a straight line — corners are what cuts the chase. Keep your hands empty during the sprint so you don't trigger a Treatment-item steal if the Hider catches you at the corner.

Advanced: if a Bed Monster is active in an adjacent room with its red hitbox up, lead a chasing Hider through the hitbox. The Bed Monster grabs the Hider for the bribe slot, eliminating both threats at once without using any of your Maple Syrup or weapon charges.

Patch History

X-Ray room dual-spawn bug is known and unresolved as of the 2026-06-28 Fandom snapshot. No balance changes to Hider damage, chase duration, or theft rate are documented.

Frequently Asked Questions

How do I spot a Hider before it activates?
Look for the grin and eyes — those don't camouflage. The body colour matches the wall, so you'll see a face hovering over a faint outline.
What triggers a Hider to chase me?
Looking directly at one while closing the gap. Distance viewing is safe; the activation happens when proximity drops below a threshold with eye contact.
How long does the chase last?
5 to 6 seconds. After that the Hider evaporates whether it caught you or not. Breaking line-of-sight around a corner ends the chase early.
What happens if a Hider catches me?
Sanity damage plus a high chance of having a Treatment item stolen from your hand. Don't carry irreplaceable items into known Hider zones.
How many Hiders can spawn at once?
Groups of 1 to 6 per zone. The X-Ray room has a documented bug where two can overlap on the same wall.
Which weapons work best against Hiders?
Fire Extinguisher, Taser, and Gun all work. All three function whether the Hider is dormant on the wall or actively chasing.
Can I bait Hiders into another enemy?
Yes — lead a chasing Hider into a Bed Monster's red hitbox. The Bed Monster grabs the Hider for the bribe slot, eliminating both threats without using your supplies.
Does avoiding eye contact stop the activation?
It reduces the trigger window but doesn't eliminate it at close range. Proximity alone can activate a Hider if you walk right past one, even with the camera angled away.

A wall-flat enemy with three behaviour phases

Hiders move through three documented states:

  1. Flat on the wall — visible as a 2D silhouette painted on a corridor surface. Passive.
  2. Drop into 3D — peels off the wall, becomes a standing humanoid.
  3. Short pursuit — sprints at the player briefly to grab an inventory item, then retreats.

The detection beat is recognising the flat-wall state before phase 2 triggers. Once Hiders are 3D, your window for a clean Fire Extinguisher hit narrows.

Two valid counters, situationally

Per Destructoid + community sources, both Fire Extinguisher and Taser work as direct counters. Practical choice:

  • Fire Extinguisher — wider area of effect, more total uses per refill. Better if you're not sure exactly which corridor segment they're in.
  • Taser — precise, fewer uses. Better if you've already spotted the 3D silhouette and have a clear line.

If both are on cooldown or out of charges, the fallback is to sprint past corners until they fade out of pursuit. They have a short chase range and disengage on their own if you break line-of-sight long enough.

What they steal

The inventory-item grab is the cost of a failed encounter. Hiders don't kill you; they remove a treatment item or utility from your bar. If you were carrying a Fire Extinguisher and forgot to swap to it before they reached you, the irony is they may grab the very item you needed for the next room.

Stack discipline: keep counters in adjacent inventory slots so a quick swap is possible even mid-encounter.
