Mass Pike Interchange

Fallout 4 guide · clearing the gunner base

Mass Pike Interchange is a multi-level Gunner fortification built across a section of collapsed highway. Players must take a yellow personnel elevator to reach the elevated road, eliminate heavy Gunner defenses, and defeat their commanding officer. Clearing the site requires navigating traps, automated turrets, and high-damage enemy explosives.
