There’s a new patch out today for Fallout 76, and along with the usual bug fixes and adjustments comes a brand-new questline. Called "Lying Lowe," the quest sends players hunting for clues to help determine the fate of a pre-war brother and sister, who may have crossed paths with a legendary West Virginia cryptid called the Sheepsquatch.

The adventure begins in Lewisburg, where players can find posters put up by someone named Shelley van Lowe. It seems Shelley was in search of her brother Calvin, and believed that he may have met a gruesome fate at the hands of the Sheepsquatch—the "fabled wooly terror" of West Virginia, according to Bethesda.
