Casterfell Dam Data Store Junction Box Puzzle Guide

Locate the Casterfell Dam Data Store in the far north of Casterfell Woods at coordinates 22.5E, 92.4N. Follow the main road north from Village Outskirts, then head west, passing the Garden Center Landmark. Descend through rubble, being mindful of potential Druid patrols, to find the entrance.

Inside, proceed through the hallway to a large room patrolled by a robot. Loot an open crate and find a crawlspace on the left wall to enter the Security Room. Loot the room and use the Pneumatic Tube if needed.

Exit the Security Room via the north door. Wait for the robot to pass, then slowly follow it to the Electrical Room in the northwest corner. This door is locked and requires the Dam Data Store keycard. Progress Dr. Garrow's Lead until she provides the keycard (she sends you here).

With the keycard, unlock the Electrical Room door. Activate the junction box at the back of the room using the Signal Redirector. This will turn on the vents in the main room.

As you leave the Electrical Room, a turret will activate at the bottom of the stairs. Descend carefully and hug the concrete pillar the turret is on. When the turret's laser points away, quickly move around and activate the junction box on the pillar to disable it. Be aware that this also spawns an endless stream of rats from the vents to the right of the Electrical Room; use an Explosive Lure or quickly proceed to the next junction box.

The next junction box is on the ceiling in the center of the main room. Climb the crates to the east of the pillar junction box, then onto the server to reach and activate this junction box.

Activating the center junction box opens the Control Room in the southeast corner and activates another turret on the pillar in front of the Control Room stairs. Wait for the turret's laser to pass to the right, then sprint up the stairs into the Control Room.

Inside the Control Room, ascend the stairs and press the button on the console to the north to power up the facility.

Return to the main room and activate the button on the small terminal located below the now-deactivated turret. This completes the puzzle and presents a choice regarding the Gen Era or Gen Move.
