Fallout 4: Automatron

Automatron is the first DLC for Fallout 4. It takes the player on a quest to stop the mysterious Mechanist who has unleashed a horde of evil robots into the Commonwealth, including the devious Robobrain. The player has to be at least level 15 to see the quest Mechanical Menace pop up. Mechanical Menace instructs you to listen to a caravan distress frequency, which will lead you to a besieged caravan by Watt’s Consumer Electronics.

The general objective of the Automatron DLC has the player restoring peace and order to the Commonwealth, by destroying the malfunctioning robots that are threatening the citizens. Automatron adds 5 new quests and five new achievements. A large number of items have also been added.

Additionally, this DLC adds the possibility to build and mod your own custom robot companions. Very much like the Power Armor modification, you can mix and match limbs, armor, abilities, weapons and even voice patterns.
