Fort Hagen Satellite Array

Fallout 4 guide · assaulting the robot army base

This location serves as the heavily fortified subterranean lair for the Rust Devils raider gang and their cobbled-together robots during the Automatron DLC storyline. You must fight your way down through the dish installation into the hangar depths to recover the second Robobrain beacon. The assault culminates in a chaotic boss arena fight against the Rust Devils' mechanized leader and a reprogrammed sentry bot.

Tips

Bring weapons optimized for energy damage or high armor penetration, as nearly every hostile here is either made of metal or wearing power armor.
You can use the terminal overlooking the final arena to tamper with or disrupt the arena spotlight systems before jumping into combat against Ivey and Ahab.
Target the fusion cores of the Scrap Sentry Bots when they overheat to trigger an immediate, devastating explosion that clears out nearby raiders.
