Automatron adds several new weapons, outfits, armor pieces, and rather than present an entirely new area has opted instead for tweaking several current locations, though the tweaks are substantial enough to make the areas stand out, and there's certainly no shortage of "Phat Lewt" in these changed locales.
The basic premise of Automatron is that a familiar-sounding fellow called The Mechanist has unleashed an army of homemade robots onto The Commonwealth under the guise of peace. In reality, the machines are killing just about anyone they come across, and it is up to you as the only person who can get shit done to put a stop to it. You are aided in this quest by Ada, a new Robot companion (Who you may also tweak to your whims), and the entirely new mechanic of Robot Workbenches. This is the meat of this DLC, and I'm happy to report it's very well realized.
