Control sightlines, movement, and distance first. These threats usually punish panic more than aggression.
Enemy Guide
Control sightlines, movement, and distance first. These threats usually punish panic more than aggression.
Do not freeze, over-watch, or turn a hallway problem into a full-team panic response.
These enemies are often route and awareness checks, not straight damage races.
Hiders become expensive when you are already holding the exact cure or support item the run needs next.
If you protect the item path and keep awareness high, the threat becomes much less dramatic.
Most Hider losses come from moving carelessly between desk, rooms, and storage, not from failing a combat mechanic.

Threat reference art
Current wiki reference image for this specific threat, used to avoid mismatching one enemy with another.
A wall-camouflaged swarm threat that steals the treatment item you are holding if it hits you.
Spot them before contact, then use extinguisher, taser, gun, or raw movement to avoid getting clipped while carrying medicine.
Hiders are described as paper-thin creatures that blend into walls and can spawn in groups of 1 to 6. Their main punishment is knocking the held item out of your hand, which can ruin time-sensitive treatment routes.
Carry threat
Hiders matter most because they steal from you while you are already doing something important. Awareness beats brute force here.
Encounter context
Enemies become much deadlier when you are already juggling sanity, room routing, and event timers. Good play is usually about composure, not just reaction speed.
Community guides do not always use exactly the same label for this threat. This page follows Hiders, while also noting the alternate phrasing: Wall-camouflaged anomaly swarm.
Do not rush through wall-heavy rooms while holding a critical item you cannot afford to drop.
If this threat keeps wiping you
Open treatments when the issue is not spotting Hiders, but protecting the exact item you still need.
Use the room route page when the theft keeps happening in the same movement patterns.
Sometimes the answer is changing what you carry, not only how you react.
Best next step
Open this if Hiders mainly wreck you while carrying cures through treatment rooms.
Use this when the bigger issue is which items you keep exposing to the threat.
Open this if you want the broader short-rule sheet for handling roamers and item threats.
Open the full enemy hub when you want the whole threat list instead of one encounter alone.
Useful when this threat becomes dangerous mainly because it overlaps with room pressure or timed emergencies.
Best follow-up when this enemy causes wipes because panic, hesitation, or bad recovery snowballs too fast.
