Fallout Shelter resources

Resources are a core gameplay component of Fallout Shelter. Managing them properly is essential to maintaining the well-being of a Vault.

Primary resources
There are three basic resources in the game:
 * Power: The vault cannot run without power. If power runs low, rooms will begin shutting down. Rooms which are most distant from the generator room(s) will shut down first.
 * Water: Clean water is hard to come by in the wasteland. Running low on water will result in the vault dwellers taking radiation damage. Excess water will negate their radiation damage over time.
 * Food: Dwellers need to eat to stay healthy. Running low on food causes dwellers to lose health. Excess food will heal dwellers over time.

Secondary resources

 * Vault dwellers - used to gain resources, go on quests, perform tasks, etc.
