Fallout Shelter

In the irradiated aftermath of nuclear devastation, players assume command of an underground Vault as its Overseer, responsible for transforming a sanctuary into a functioning society. Survivors fleeing the toxic wasteland arrive seeking refuge, and it falls to the player to nurture them through resource management—maintaining adequate food supplies, power generation, and morale while methodically expanding the subterranean complex. The vault dwellers face constant peril from external threats including raider incursions, mutant infestations, and other environmental dangers that test the Overseer's ability to protect their growing population and maintain stability in humanity's last refuge.
