Survival Mode (Fallout Shelter)

Survival mode is an optional difficulty setting in Fallout Shelter that presents a higher level of challenge to experienced overseers.

Survival mode is enabled by checking the corresponding box above the vault number selection when creating a new vault. It cannot be enabled or disabled from an existing vault.

When selecting the Survival mode button while creating a vault, the game will display a message advising the player not to choose this difficulty unless they are experienced.
