Fallout 4: Poseidon Energy (The Glowing Sea) Fallout 4 Guide

An abandoned facility that consists of few annexes outside and a large area inside the complex. The whole area is swarming with large number of ghouls and among them you can meet both legendary and glowing opponents.

Outside, while walking upstairs you will find a group of ghouls, with one legendary among them. Inside you can find few valuable items.

It is easy to miss the entrance if you don't keep attention while walking around the building.

You can get inside through the door on one of the walls (entrance is on the ground level).

Just after entering the building in the room on the right side you will find a terminal that open the door leading to the southeastern part of the complex. There you will find one glowing ghoul and a safe on master level. It contains some ammunition, few armor parts and a good weapon.
