How do activated Maintenance Shafts affect adjacency and range?

Question

Accepted Answer

For the Final Girl an activated shaft makes the two rooms adjacent for movement and, mechanically, for range, so a range-1 Flamethrower can shoot across (a table may use Rules of Ambiguity to disallow it). Enemies can't use shafts, so the far side is not 'closest' for a Killer or Evomorph. Finish your current action before using a keycard to open a shaft.
