Project Clean Appalachia

"You've bravely left Vault 76 for the untamed wilds of West Virginia, unlocked the secrets of the Wasteland, and maybe even made a few friends (or enemies) along the way. What's next?

Vault-Tec has the answer: Project Clean Appalachia! As a former dweller, it is YOUR responsibility to restore the region to its former glory and allow survivors to resettle some of the most beautiful land America has to offer - starting with hazardous wildlife.

Join other dwellers in exterminating pests over the next six weeks, and Vault-Tec is prepared to reward everyone for their dedication to rebuilding this great nation with special cosmetics, steep discounts at The Purveyor, and the return of fan-favorite Meat Week!

Happy Cleaning!"
