A roleplaying game of apocalypse survivors, emerging from an underground bunker decades after the fall to discover how the world has changed.
One day, the Vault opens and they taste the wind and see the open sky for the first time. Having absolutely no information about how the world has changed, they're unequipped and unprepared to deal with what they are bound to encounter. What will they discover when the door of their Vault opens? What new world awaits their sheltered eyes and unguarded brains? How will their confrontation with what's out there transform their relationships to each other?
