As you explore the world ofAtomfall, you’ll likely come across radio towers, locked up tight and inaccessible. If you’re familiar with open world games, chances are good that you’ll search high and low for ways to get in and see what secrets they hold; these sorts of things exist for a reason, after all.

Atomfall’s radio towers are a key part of one specific storyline. If you’re working toward unlocking Joyce Tanner’s ending, you’ll need to visit and activate all three towers. This guide has everything you need to know to make it happen

Slatten Dale

31.0E, 75.0N

Once you enter a radio tower, you’ll need to find its keycard to actually power up its console. Luckily, each has a note saying where the keycard was last seen.

How To Find The Casterfell Woods Radio Tower Keycard

The keycard to activate Casterfell Woods' radio tower is inBunker L9, below the dam in the northwest. The coordinates of the entrance are23.3E, 90.6N. The area is fenced off, but you cansqueeze through small gaps in the fenceto get inside, then unlock the gate from within.

You can also go through the gas-filled tunnel across from the entrance to theDam Data Store, but it’s not usually worth the damage you’ll take unless you really don’t want to sneak past the Ferals beyond the fence.

The inside of Bunker L9 is crawling with Ferals; again, you’ll have to either deal with them or brave poison gas to get the keycard.

Avoiding The Ferals

To avoid the Ferals,go through the vent to the leftand make your way to the office above the entrance.Drink an Antidoteto increase your Poison Resistance, thenrun into the office and grab the keycard from the desk on the right.The longer you stay, the more damage you take, so be quick.

How To Activate The Vents

If you have aSignal Redirectorand don’t mind fighting the Ferals, go ahead to the main room andtake an immediate right.The Feral behind the crate will wake up and attempt to spit spores at you, and the ruckus will likely attract the rest of the pack.

Once the Ferals are all dealt with,continue clockwise around to the room with the vent controls.You can use the Signal Redirector through the wall to switch the Junction Box, orgo around and through the hole in the wall outsideto get eyes on it directly. Once the box is switched,turn on the ventsto drain the poison gas from the office, then go upstairs and get the keycard.

Climb through the office window onto the catwalk over the warehouse to find abriefcase with the Combat Stim crafting recipe inside.

How To Get The Skethermoor Radio Tower Keycard

The note inside Skethermoor’s radio tower indicates that the keycard has been taken to “the nearby bunker.” It refers to theVehicle Depot Bunker, a short walk to the east. The main entrance is covered in rubble, so you’ll need to use thesecondary entrance up the hill to the northwest, at 43.4E, 74.6N.

Outlaws patrol the ruined greenhouses near the main entrance. While they don’t usually go up the hill, there’s a possibility that they’ll see you from below and close in.

The bunker is also occupied by Outlaws, and most of them have guns.Use the cover at the top of the stairswhen entering the main room to fire back at them, andthrow a grenade when they group together.If they close to melee range, fall back to the entryway if necessary.

Once the bunker is cleared,go to the room at the rear left, under the stairs. Crawl through the hole in the wall andclimb the cratesthat you find. At the top,crawl through a vent in the floor on your rightto reach the locked office at the top of the stairs. The keycard is on the large square of desks in the center of the room, and there’s aNail Bomb Recipetacked to the far wall.

How To Get The Slatten Dale Radio Tower Keycard

The radio tower in Slatten Dale is in Outlaw territory, specifically in the camp they have outside the northern entrance to the Slate Mine Caves. This can actually be advantageous, as it means you canreach the tower by going through the caves, then going right once you’re back outside. Doing so avoids all the Outlaws in the area unless you’re extremely unlucky and one happens to be walking by.

To get the keycard, though, you’ll need to risk being spotted;it’s in the quarry below the radio tower, and Outlaws patrol the area regularly. If you aren’t in a hurry, it can be a good idea totry cleaning the area before going into the quarryso that enemies can’t shoot at you from above.

Also stay out of the water as much as you can while in the quarry, as it’s infested with vicious lampreys that will damage you and inflict the Bleeding status effect if you linger too long.

At the bottom of the quarry, look for a cave in the eastern wall; you can either climb the flat rocks on the right or simplywalk up the fallen steel scaffolding to reach it.Inside,there’s a wooden barricade along the left hand wall toward the back;crawl through the hole in it to find a dead scientist with the keycard.

What To Do With The Radio Towers

Once you’ve gotten the keycard for each radio tower,return to the tower and use it to power the console.Joyce will confirm that the tower is online over the speaker. When all three radio towers are active,a mysterious broadcast will go out over the Quarantine Zone. If you’ve been exploring and paying attention to the notes you’ve been finding, you may recognize at least one of the code words included in the message.

Return to Joyce at Data Store Charlie, and she’ll give you the final mission of her storyline;extract a core sample from Oberon, then blow up the dig site. Following her instructions, then meeting her for extraction in Casterfell Woods, will unlock her ending and get you theEmergency ExtractionAchievement / Trophy.

If you’ve activated the Dam Data Store, Joyce will require that youcopy the data with command GEN MOVEand bring her the Top Secret Tape. If you refuse to hand it over, or delete the data before copying, you’ll be locked out from seeing Joyce’s ending even if you’ve otherwise cooperated with her.
