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.
