Rust Devils (Automatron)

Rust Devils are a hostile faction appearing in the Commonwealth in 2287.

Background
The Rust Devils are similar to Raiders and The Forged, but tend to use robotic scrap parts as armor and construct robots to defend their base. The can only be found at Fort Hagen satellite array, their base of operations, where they will attack anyone and everyone on sight.

Based on Ada's words, she and her caravan encountered them while crossing a river into a city (presumably Diamond City), utilizing robots for their nefarious practices. They scavenge throughout the Commonwealth, looking for functional robots; if theY can't capture or reprogram these functional robots, they strip them for parts, making them into armor or spare parts for other reprogrammed robots.

Appearances
Rust Devils appear only in the Fallout 4 add-on Automatron.
