Stage all four tools on floor before first Scalpel prompt. Runner stays at door with backup Coffee. No hallway breaks mid-sequence if avoidable.

Failed surgery retry doubles drain time—get prompts right first pass via calm input.

Skinwalker transformation mid-surgery aborts normal tools—combat switch overrides Tentacle lesson.

Co-op Room 8 Roles

Surgeon only inside; runner feeds Coffee cups through door without entering gaze hazards. Third player holds Extinguisher if fire event cross-triggers.

Shutter continues unless Eyeless—do not pull surgeon to window.

Call Tentacle at spawn so team knows Room 8 unavailable for item requests temporarily.
