StairwellHorror

The hunt

The Human wakes on Floor 9 and must find the Security Room Key, open the Security Room for the Exit Key, then escape through the main exit at C1. The Ghost starts on Floor 1 and wins by sharing the same space, floor and area (stairwell or corridor) with the Human.

Spaces A, B and C overlap. You always know your floor, never your space letter. Stairs twist between spaces — use the public map and your wits.

Turns

The Human moves first. Each turn has 4 steps: going up or down a flight, entering or leaving a corridor each cost 1. Skills cost energy instead. Choose End Turn to hand over. Each handoff, both players outside quantum state roll for energy: 75% +0.5, 25% +1.

Above C9 an Electronic Sun blocks the stairs.
