Fallout Shelter is the wildly successful mobile game released by Bethesda studios, developer of the iconic Fallout series. Released back in June, the game crushed all records set in the App Store, making over $5 Million in the first two weeks.
The premise of the game is simple - you are in charge of running a fallout shelter, making sure everything runs smoothly and your citizens are happy. There are in-app purchases to speed up wait times, but the game is fully free to play otherwise.
