A promotional mini expansion that introduces five alternate item cards so players can choose which version of the items they want to play with each game. The alternates retain the original spirit of the base cards but enhance or modify them to create a unique experience.

The Nightfall expansion introduces a new component and mechanic to The Stifling Dark while also adding two investigators, four items, and one cursed item.

The large flashlights cover more ground than the small flashlights included with the base game, but they can't reveal the adversary. The flashlight augments introduce ways to modify your flashlight to perform different functions that either help your fellow investigators or hinder the adversary.
