Fallout Shelter is a free resource management and strategy game that is based in the same world as the rest of the Fallout series from Bethesda. In this game, you are responsible for the creation of a survival bunker, so you must pay attention to every detail related to community interactions, resources available, and space.

Constructing your shelter is one of the best aspects of the game. You'll start with a small shelter, but as you progress through the game, you'll add more rooms that perform more functions. You can add elevators, bedrooms, generators, labs, coffee shops, weapons stores, and much more. You can even build a famous Nuke Cola factory in your shelter.

The raw materials for the buildings in your shelter will have to be collected. As you let in residents for the shelter, those residents will be able to help you with collecting resources. You'll eventually gain the ability to arm the inhabitants of your shelter so they can explore the outside world in search of resources.

Visually, this game is pretty stunning. It offers the same premium animation like you'd expect from any other Bethesda product, and since it bears the official license from the developer, the game has a lot of legitimacy.
