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

Characteristics

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.

Features

• Resources drain at a faster rate.
• Incidents do more damage, and occur more frequently.
• Vault dwellers can't be revived, whether in the Vault, in the Wasteland, or on quests. They also don't heal themselves over time inside the Vault (although they recover radiation damage).
• Objectives are more demanding, but give better rewards.
• Quests are more challenging.
• Deathclaws start appearing at 35+ dwellers instead of 60+.
