You are a vault dweller in Vault 63. The mission of this vault is to prepare for the repopulation of the surface world. In order to do that, the vault requires more women than men. On every male's 18th birthday, they evaluated, and only the most virile, the top 20% of men, get to remain men. The rest go through a mutagenic process that turns them into women. You are one of these new women. Will you resign yourself to your fate as a woman in Vault 63, or will you escape and try your luck in the unforgiving, post apocalyptic surface world of Fallout?
