Bethesda Softwares new release Fallout 4 is one of the most anticipated video game releases of the year, and the company is promoting it with the Fallout Pip-Boy app, which recreates the game series iconic communicator.

The app synchronises with users progress in the main game, enabling users to check their statistics, inventory and other features while out and about, as well as access data on the game and its universe. It is designed to work in conjunction with a wearable wrist-mounted display that comes with a special edition version of the game.

In addition, players can find mini-games within the main Fallout 4 game which can then be loaded onto the Pip-Boy app, furthering their immersion. One game, Atomic Command, is included when the app is downloaded, while others must be discovered as players explore the games open world.

The app is the latest in a series of mobile promotions the company has created for the game, including a dedicated emoji keyboard that uses images, graphics and GIFS from the game, and the Fallout Shelter game which places users in control of an underground vault that has survived a nuclear attack and must manage its supplies and build a thriving community.

Fallout Shelter topped iOS and Android charts in multiple countries and the iOS version was played 70m times a day during its first week of release.

“We play games on our phones all the time, and have always wanted to make one,” said Todd Howard, game director at Bethesda Game Studios. “To have our first mobile game be enjoyed by so many is stunning. It just shows that gamers appreciate more depth and being treated fairly.”
