Bonus Adventure: A Halloween Night Out

The monsters crash a hospital canteen turned party. But danger lurks beneath the decorations:

• The retiring head nurse is secretly a monster hunter.

• The night guard is undead—and starving.

• A relic in the morgue is stirring restless spirits.
  To top it off, Joannie, a reckless teenager, has wandered in and needs protection before she blows everyone’s cover.

This two-hour one-shot includes NPCs, ready-to-run problems, and rising suspense that pushes the Suspicion Dial to the brink. It’s perfect for new players and veterans alike, balancing tension, comedy, and a dramatic race to midnight.
