Fallout 4 er lige ved at modtage sin første udvidelse, nemlig Automatron, der rammer PC, PS4 og Xbox One d. 22 marts og koster cirka 75 kroner. Bethesda har netop givet os den nyeste trailer, som har følgende beskrivelse:
In Automatron, the mysterious Mechanist has unleashed a horde of evil robots into the Commonwealth, including the devious Robobrain. Hunt them down and harvest their parts to build and mod your own custom robot companions. Choose from hundreds of mods; mixing limbs, armor, abilities, and weapons such as the all-new lightning chain gun. Even customize their paint schemes and choose their voices! (For characters level 15 or higher.)
