Located in the bombed out ruins of Rio Bravo, Mexico, La Ciudadela as it was nicknamed during construction is among the few large scale Vault-Tec imitations in Latin America that succeeded in its goal to keep its occupants alive. Since the bombs fell and Rio Bravo was burned off the face of the earth in nuclear hellfire, La Ciudadela has remained safe and secure and more recently has become the palace of the self-proclaimed “Reyes of Mexico” who have run the vault and the surrounding shantytown with an iron fist and self-interest in their goal of establishing a new Mexican Empire and more recently, in defeating Pancho Mendoza’s communist People’s Legion who seek to open the vault’s amenities to the poor paisanos who live outside it, or so they claim.
