Casterfell Dam is an important location inAtomfall, though it might not look like it at first glance. Early on, it’s a good place to ransack for resources, but if you’re thorough you’ll find a well-defended bunker underneath it.
The Dam Data Store is protected by a dangerous robot and locked down by top-level clearance, and it protects important secrets about the Wyndscale Plant and the discoveries that were made there. Getting to that data, though, requires some very specific events to take place. Here’s what you need to do in order to access it.
How To Reach The Dam Data Store
The Casterfell Dam takes upthe northwest corner of the map in Casterfell Woods.The Data Store is in a low section on the right side (facing the dam), and there are two main ways to approach it.
The Ferals and toxic gas mean that you shouldonly use the second route in extreme emergencies, even though it’s much shorter.
What You Need To Access The Data Store’s Secrets
The Dam Data Store has plenty of supplies to take, even if you don’t have the key to the control room, anddisabling the flamethrower robot insideon your first visit can save you trouble later on.
When you’re ready to go for the top-secret data, you’ll need the following:
Doctor Garrow carries her keycard with her at all times. To get it, you’ll need tofirst rescue her from Skethermoor Prison, which will also get you the Signal Redirector. She’ll flee to the Central Processing room in the Interchange. Meet her there and eitherkill her, ortellDoctor Holderwhere she isand he’ll do it himself the next time you return to the Interchange. Take the keycard from her body. Alternately,recover her research notes from Roboticsand she’ll give you the key if you agree to continue working with her.
Obviously, killing Garrow you out from continuing her storyline.
Joyce Tanner appears in Data Store C after it’s powered up at the Interchange;help her activate the radio towers around the Quarantine Zoneto get her on your side.
How To Get The Top-Secret Data Tape
Once you have Garrow’s Dam Data Store Keycard,return to the DamBunkerand climb the stairs at the rear left. Use the keycard to enter the locked room, thenuse the Signal Redirectoron the junction box inside. Watch your step as you leave, as this will haveactivated the turret at the bottom of the stairs.
Carefully make your way to the other side of the turret’s pillar;equip an Explosive Lure to a quick slot,use an Antidote, then use the Signal Redirector on the second junction box to disable the turret. This willactivate the vent on the far wall, allowing a constant swarm of rats to come in.
The rats' nest isinside the vent, so you can’t destroy it. The only way to stop the rats is toswitch the next box, by the doors on the right side of the room, as quickly a possible. Throw an Explosive Lure at the swarm to distract them, thenrun to the junction box.Finish off any remaining rats with melee attacks.
Loot the rooms that the box opened, thenclimb onto the pile of crates in the center of the room. This will put you within reach of thefinal junction box, on the ceiling.Switching it on willopen the door to the control room, up the stairs on your left if you’re facing the entrance.
Go into the control room anduse the center console to turn the main power back on.Joyce will come in on the speakers and give you the command to transfer the bunker’s data to a tape. She’ll alsoinsist that you bring it to her, or she’ll stop helping you.
Return to the main room anduse the terminal next to the pile of crates that you climbed(it looks like an arcade booth). Use the commandGEN MOVEto transfer the data and get the Top-Secret Tape, orGEN ERAif it was given to you by Doctor Garrow to purge the data. If you want to play both sides, you can do both; just be sure to useGEN MOVE before GEN ERA,or there will be no data to copy.
