Fallout – Does radio studio upgrade increases happiness level

fallout-shelter

In Fallout Shelter it says, that radio studio increases dwellers happiness level. Does upgrade of this room increases this effect?

Best Answer

The radio room serves two purposes:

  1. To entertain dwellers in your vault
  2. To broadcast into the wasteland to attract more dwellers

As @camelCase stated already, high Charisma increases the happiness of dwellers in your vault, as part of #1 above. Upgrading the radio room serves to point #2, in that it increases the chance of attracting a dweller. Expanding (adding additional rooms) of the radio room and putting additional dwellers into the radio room serves to make the cooldown for the search for dwellers to take less time.

So if you're interested in only keeping existing dwellers happy, high Charisma is what you want. (Plus probably a 3-room expanded radio room, so you can have the maximum number of high Charisma dwellers broadcasting)

If you're interested in finding dwellers in the wasteland, you'd want to focus on upgrading and/or expanding the radio room (or both) faster, and in my experiences, Charisma doesn't seem to have any affect on dweller-finding.
