Fallout 4: Automatron

Automatron is a story expansion for Fallout 4 in which a mysterious Mechanist sends aggressive robots into the Commonwealth. You track down the origin of the machines and can assemble parts of defeated enemies into your own robot companions. Fallout 4 is required to play.

Automatron released on March 22, 2016 for PC, PlayStation 4 and Xbox One. Native versions for PlayStation 5 and Xbox Series X|S followed in April 2024. Since February 24, 2026, the expansion has also been part of Fallout 4: Anniversary Edition for Nintendo Switch 2.

Automatron is available for PC, PS4, PS5, Xbox One and Xbox Series X|S. The PS5 version is part of the native port of Fallout 4 and requires the corresponding main game. On Switch 2, Automatron is included in the Anniversary Edition, without requiring a separate DLC purchase.

The Mechanist deploys hostile machines in the Commonwealth, including Robo-brains. After battles, you can collect their components and use them for a self-built companion. This way the expansion links new quests with a lasting robot building and equipment system.

Automatron was the first major Fallout 4 expansion. It is included in the Season Pass along with Wasteland Workshop, Far Harbor, Contraptions Workshop, Vault-Tec Workshop and Nuka-World. The Game of the Year Edition and the Anniversary Edition also include the add-on.

The expansion requires Fallout 4 on PC. On Steam, the minimum requirements are listed as 8 GB RAM, a 64-bit Windows system, an Intel Core i5-2300 or AMD Phenom II X4 945, and a GeForce GTX 550 Ti with 2 GB or Radeon HD 7870 with 2 GB. The details come from the original PC version.

The Mechanist is the central antagonist of the expansion. You encounter his machines in the Commonwealth and work your way through the new story to its origin. The story remains closely tied to the new robot enemies and the self-built companions.

At the robot workbench, you combine body parts, limbs, armor, weapons and other modules. Bethesda describes hundreds of possible builds, including chain lightning weapons. Colors and voices can also be changed. This creates companions with different combat roles.

The Automatron quest line is aimed at characters from level 15. If you want to follow the Mechanist and use the robot workshop, you also need the installed expansion and Fallout 4. The story can begin within an existing save game.

Automatron is an add-on for the single-player RPG Fallout 4. The Steam version supports German user interface, subtitles and voice audio. The expansion has no standalone co-op or online game mode.
