Fallout Shelter is the No. 1 downloaded game in 48 countries

The first mobile Fallout game has everyone coming out of their shelters.

Fallout Shelter, a mobile game about life in a post-apocalyptic world, is now the top downloaded free game on the App Store. Bethesda released the title at last week’s Electronic Entertainment Expo (E3), and it only took about two days for it to knock mobile game juggernaut Candy Crush out of its top-grossing spot in the United States. That growth continues — Bethesda announced today that Fallout Shelter is the No. 1 downloaded game in 48 countries, and the top downloaded app of any kind in 25 countries.
