Fallout 4’s first expansion ‘Automation’ will be available from March 22 on Xbox One, PC and PS4.

The mysterious Mechanist has unleashed hordes of evil robots and it’s up to you, John Connor (or whatever your Fallout 4 character’s name is) to create your own custom robot companions to fight metal with metal.

Choose from hundreds of different parts, weapons and abilities to customize your robot. You can even customize the looks from paint schemes and personalize it with various voice packs.
