Fallout 4's first add-on, Automatron, is almost here, and we're excited to share the official trailer with you today. Automatron will be available for download across Xbox One, PlayStation 4 and PC on Tuesday, March 22.

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.)
