What is Vault+ Service?

These are permanent upgrades and daily services that you can purchase to increase your Vault’s security, capacity etc. Go to your Manor’s controller, then select Vault. Go to the Vault+ tab to see the upgrades and services. There are two tabs in the bottom: Permanent Technology and Enhance Service.

Permanent Technology costs Security Points and dollars. Here, you can purchase additional floors for your vault (which can satisfy even your most severe hoarding problem), structure cap, defense cap, and furniture cap.

Enhance Service are services that will require daily upkeep (800 Security Points and 500 dollars). Building+ increases your vault HP by 40% while Activity increases the spread of gas inside your vault by 20%.
