A tweet from the Fallout Twitter account shared the image above, which shows that a variety of festive items, including turkeys and pilgrim attire, have been added to Fallout Shelter. People on Reddit are also talking about the update, which should be available now for the game's iOS and Android versions.

Bethesda is making holiday-themed updates for Fallout Shelter something of a regular thing. In October, the developer launched a Halloween update for the game that introduced cobwebs, costumes, and cauldrons. We'd expect a Christmas/New Year's update will follow next.

This update, like others before it and the game itself, is free. Bethesda makes money from the game through the sale of in-game lunchboxes. In the two weeks following the game's release in June, it generated more than $5.1 million in revenue from iOS alone, according to one research firm.
