In the game, you are put in the role of the Overseer of a Vault of your choosing (the number is selected by you), and the goal is to successfully lead generations of Vault Dwellers to survive and thrive in post-nuclear America - which means, at the bare minimum, making it an okay place to live. The game was later ported to PC, Xbox One, PlayStation 4, and Nintendo Switch. Unfortunately, the game isn't available on the Amazon App Store, thus denying folks with uncertified Android devices access to the game. The game is available for the iOS, and beginning August 12th, 2015, also for Android devices with Google Play Store access (the release coincides with the 1.1.0 update for iOS).

The game is free to play, with in-app purchases. The game was released after Bethesda's first E3 showcase, on June 14, 2015. Fallout Shelter is a vault management Life Simulation Game set in the Fallout franchise, designed for mobile platforms, developed by Behavior Interactive and Bethesda Game Studios and published by Bethesda Softworks.
