Theme recipe fragment

Theme recipe fragments are a resource in Fallout Shelter that was added in the 1.8 Update.

Overview
Theme recipe fragments are in fragments of 9 pieces and when put together they can make a theme for any fully merged and upgraded diner and living rooms at a theme workshop.

The game's four themes are based on the four different factions featured in Fallout 4: the Minutemen, The Railroad, the Brotherhood of Steel and The Institute. Once themes have been applied to rooms, they can be toggled on and off.

Collecting theme fragments after all themes have been unlocked results in receiving caps or recipes for weapons and armor.

Obtaining theme fragments
There are two basic ways of obtaining theme fragments:
 * Spending 27-3 Nuka-Cola Quantums to unlock a theme.
 * Completing quests from the overseer's office
