In this game, you play as the Overseer of a vault. In the Fallout universe, Vaults are self-sufficient subterranean shelters where people thrive even after the nuclear apocalypse. You have all the powers and decision-making how to run your Vault and take care of the dwellers. This might remind you of a Sims-like gameplay since you'll not only have to manage your Dwellers' needs but also their happiness and well-being.
