How do I turn on Survival Mode?

The release notes for the latest version of Fallout Shelter include the following item:

  • Faced all the challenges the "normal" Vault simulation can provide? Introducing Survival Mode! More danger, More glory. Make Vault-Tec proud.

I have gone through every menu item in the game and started a new vault, but I cannot figure out how to turn on Survival Mode. How is it turned on?


Solution 1:

You have to start a new vault. It has a box to check if you want to play survival mode.
