Immerse yourself in a whiteout nuclear winter in the first quest book for Fallout: The Roleplaying Game.

In the ruins of old Boston, the Commonwealth settles in for a long, deadly winter. As its hungry communities do their best to find food and survive the cold, a new sect of the Church of the Children of Atom arrives. Their flock grows as they spread their worship of nuclear division and radiation across the region. Led by an enigmatic prophet calling himself the Last Son of Atom, the Church's army plans to ignite an all-out winter war with the settlements that dare reject their atomic god. A group of ragtag survivors must do whatever it takes to protect their communities and keep the Commonwealth from becoming ground zero... again.

Winter of Atom's themes include exploring frozen wastelands, harsh winter survival, building relationships with communities, explosive action against terrifying monsters, high-stakes warfare against a relentless foe, and weird and unexplainable supernatural horrors.
