If you’ve been following Joyce or Dr Garrows Leads in Atomfall, you’ll end up in the Casterfell Woods Dam Data Store, where you’ll need to make an important choice. Before you get to that though, you’ll need to figure out a perplexing puzzle inside the building. The puzzle involves redirecting the circuit around the room allowing you to press the button on the console at the front of it. Read on to find out the solution to the puzzle.

Casterfell Dam Data Store Location¶

The Casterfell Dam Data Store is located in the far north of Casterfell Woods at these coordinates: 22.5E , 92.4N. The easiest way to find it is to follow the main road north from the Village Outskirts, and then head west at the top. This means going through the Garden Center Landmark as you progress north. When you reach the area where the Data Store is, you’ll need to follow the rubble down to the bottom, but be careful of the Druid patrol that sometimes walks near it. At the bottom, you’ll find the door leading to the Data Store.

Junction Box Puzzle¶

When you enter the building, you’ll be in a hallway leading to a large open room, and if you wait a minute, you’ll see a large robot patrolling clockwise around the room. Go forward until you reach an open crate on its side and loot at the wall to your left to find a crawlspace (at the top) into the Security Room. Climb into it, loot the area, and use the Pneumatic Tube if you need it.

Exit the room via the door to the north, and wait for the robot to walk past you. Slowly walk behind it while heading to the Electrical Room situated in the northwest corner of the room. This door will be locked and requires you to have the Dam Data Store keycard, which involves you progressing Dr Garrow’s Lead up until the point that she gives you the keycard (she sends you here) in the Skethermoor Prison. With the card in hand, unlock the door and head inside.

At the back of the room is a junction box that you can activate with the Signal Redirector, equip it if you haven’t already, and then press the button on it to turn on the vents inside the main room.

Be careful as you leave because now a turret will be activated at the bottom of the stairs. Make your way down the stairs and hug the concrete pillar that the turret is on. When the laser points in the opposite direction, quickly walk around and activate the junction box on the pillar.

Note that when you do this, it will activate the vents to the right of the Electrical Room, which will spawn an endless stream of rats until you activate the next junction box. This is a great time to use an Explosive Lure if you have one, otherwise run to the next junction box, which is on the ceiling in the center of the room.

You can reach this by climbing the crates to the east of the junction box you just activated. Climb these onto the server and activate the junction box.

This opens up the Control Room while also turning on another turret. The Control Room is in the southeast corner of the room and the turret will be on the pillar just in front of the stairs. Wait for the laser to pass to the right and then sprint up the stairs into the Control Room. Inside the room, head up the stairs and press the button on the console to the north, which will power up the facility.

The last thing to do is to hit the button on the small terminal back in the main room (below the now deactivated turret) and you’ll have an important choice to make, which you can find out what that entails by reading our Gen Era or Gen Move Choice Guide.

That’s it for the puzzle, you can make things easier on yourself by disabling the Robot, but as long as you stay behind it, you’ll be fine. Also, there is plenty of loot to be found in the side rooms in this facility, including a BARD crate and some Training Stimulants.
