Fallout 4 Guide: Far Harbor Memory Puzzle Solutions GameGuides  Fallout Guide Fallout 4 DLC Fallout 4 Fallout

One of the best things that Fallout 4 Far Harbor did was expand the variety of quests that were offered in the game. Many felt that Fallout 4 lacked a lot of the richer quests that previous games had, with most boiling down to travelling somewhere and killing everything you saw. However, one of these unique missions is causing a bit of controversy, with some having a lot of trouble figuring it out. This is the Dima’s memory puzzle quest, better known as “Best Left Forgotten”

This quest puts you into a computer simulation where you need to retrieve the memories of Dima, the synth leader. To do this, you need to use all of your Workshop knowledge and skills, because there is no direct combat. Instead, you have to destroy walls, and build bridges so that little computer bots can get to the memories. Some of these are pretty easy, but they ramp up in difficulty fast. So, here are the memory puzzle solutions for Fallout 4 Far Harbor.

Fallout 4: Far Harbor Memory Puzzle 1

This is the easiest memory puzzle found in Far Harbor, but they still don’t start you off all that easy. Thankfully, Dima’s voice will help you along. Just grab the nearby blocks, or store them for use later. Use them to build a bridge to the next platform. Here you are introduced to the red walls that will block your progress throughout. To get rid of it, you need the green laser beam to hit the cube on the wall. Move the block that is in the way, and it will disappear. Build another bridge and the bots will have all the access they need. Drones will begin flying in to take them out though, so build your turrets along the path they take and you should be good to go.

Fallout 4: Far Harbor Memory Puzzle 2

Walk forward just a little bit and there will be a platform on the left. Head down there and grab the block to free up the green laser. Then just follow the pathway forward, storing any blocks along the way, and clearing the path of the green laser. Eventually you’ll find a new decoder relay, which is able to redirect the green laser beam. Put it on the stack of two, with the green side facing the right, or where you want the green beam to go. If you sent it through the hole on the right then it should clear away the red wall, but there is one more left. You now need to grab the code blocks and decoder relay on the left, and all around the platform, then build a tower (two code blocks, and the decoder) in the green beam’s path, sending it toward the key block in the final red wall. Build a bridge to the final platform, and set up some turrets here, and near the original entrance, and you’re all set.

Fallout 4: Far Harbor Memory Puzzle 3

Go ahead and store the code blocks in front of you, then use them to build a bridge to the next platform. turn left and hop up the stairs, then build a way across to the alcove above the red wall. Store everything inside, and retrieve the blocks used for the walkway, then head back down. You now need to get rid of the large red wall nearby, so build another tower. This one should be two code blocks tall, with the decoder relay on top, and be sure to place it so the green beam will hit the blue block inside the wall.

This should open up a new alcove full of blocks, so just store them all for later use. Behind these you should see a “decoder beam array” wedge into the wall (it’s the glowing block beneath the green section). Move your previous block tower so that the green beam hits this block. You can go ahead and place some turrets here if you want, they’ll be needed later. Also, go ahead and build a bridge across to the platform on the right.

You aren’t going there just yet though. Head back upstairs where the green beam is now travelling. Far down the path is another red wall with a blue block inside, build another two code block tall tower right in the path of the beam and place a decoder relay on top pointing right at it. This clears away the last wall, so just build bridges to the final platform, and place some turrets along the walkway to finish up.

Fallout 4: Far Harbor Memory Puzzle 4

Alright, things are starting to really heat up. Turn right and grab all of these blocks, then build into the center area so that you have a tower of two code blocks right in the center. Place the newly acquired decoder relay on the top, facing to the left so that it hits the red wall there. Head in and store all of the items inside, then move back to the center. Remove one block and move the decoder relay down, pointing it now toward the front. Now look to the right corner where you will see the glowing blue cube. Build a bridge in front of the current decoder relay tower you have built, so that you can set the second decoder relay where it will direct the beam to the other key block, which should be three out, and one code block high, with the decoder relay on top. Once the wall disappears you should store all the blocks used here for further use.

Now head downstairs via the stairs on the right. Toward the back, where the green beam is, build a bridge out and place a decoder relay on top, pointing forward (toward the end). Now follow the beam to the broken section, and look to the right to see where you need to hit. Put one code block in the ground under the beam, and the decoder relay on top, pointing right to hit the decoder array. This will eliminate the final red wall, so just go through and build your bridges and turrets where necessary.

Fallout 4: Far Harbor Memory Puzzle 5

Alright, this is the real tough one. Memory puzzle 5 puts everything you’ve learned so far in Far Harbor’s memory quest and puts it to the test. It’s really one of Fallout 4’s toughest missions, but it is also optional. However, without it you can’t get the best armor in the entire game. To start off, just grab every block you see around the platform, storing them for later use.

Now, with your back to the red firewall, build a bridge to the right platform. Explore this whole section, storing every block you find, then head back. Do the same to the platform on the left (again, facing away from the end firewall), building a bridge and grabbing all of the blocks there (if you need more blocks just head to the center platform. Be sure to grab the blocks you used for the bridges, you’ll need all you can get.

Once you’ve raided all of the nearby platforms, head to the center area where you’ll find the green beam firing from the ceiling and hitting the center of a pyramid. Store all the blocks here if you haven’t already, and use the decoder relay in the center to eliminate the red wall to the left. This just requires two code blocks in the middle, with the relay on the top. Build a bridge and set up a tower in the middle that is three code blocks tall, with a decoder relay at the top, pointing toward the red firewall at the back corner. Grab the blocks, but leave the decoder relay in place, then head back to the center.

Now head straight toward the back, building a bridge as you go. Store all of the blocks on this massive platform, then build a bridge to the platform at the back left, grabbing the decoder relay there. Set up a tower that is three blocks high, and place the decoder relay right in the path of the beam, pointing it back the way you came. This should have the beam heading right through the previous platform and into the decoder array at the back right. If not, make sure you grabbed all of the code blocks here.

You should now see the green beam firing up all the way to the left (facing back toward the last red firewall). You need to use this to eliminate the last two walls, so head to the platform that it is firing into, and go to the top of it. The green beam should be hitting the ceiling of a small room. Collect any code blocks you missed, and set up a decoder relay so that it fires back the way you came, via the lower hole. So just build one block on the floor, and the decoder attached to it. This clears one of the red walls, where you can go and grab the final decoder relay.

Now, you need to go back to the large, center pyramid and build a bridge out to the right, where the beam is firing up from below. Build a tower that is two blocks taller than your bridge and place a decoder relay on top, facing toward the final red wall (to the right of your bridge). Then delete the tower and bridge blocks. Head all the way back to the beginning, and off to the right where the beam is flying by. On the edge of this platform, with the beam over your head, build a tower that is two blocks tall with the decoder relay on top, pointing to the right, toward the red wall again. Head back to the original spawn point and build another tower two blocks tall, with the decoder relay pointing right at the key block on the final red firewall. Build your bridge and a few turrets and you’re finally done.

That was certainly one of the toughest, but also more unique missions in Fallout 4 Far Harbor. Hopefully this guide helps you get through it. And check out our other guides for more tips, including where to find that armor that you just earned.

    Fuck Puzzle 5, Fuck these Portal-wannabe puzzles, and fuck the stupid voice that constantly plays in the background

    • John

      Why the hell do people have to complain about everything? Seriously, nobody is satisfied. They give us content that changes things up from the other mission types, and people still bitch. Get a fucking life you dissenting douche.

      • Butts

        It sucks because it changes, I just wanna shoot things

        • ShirtAndTieler

          You literally have the entire game to “just shoot things” – that’s the #1 thing that this game is good at. Plus, this quest is *optional* meaning you don’t *have* to complete it…

  • Niles Miller

    On the final puzzle I collected everything and was thinking on how to do it when all of a sudden the 5 turrets i placed near the door were shooting at an orb and one of them missed and hit the target…. the wall collapsed and I was like seriously I spent 15 minutes collecting everything on the map to do this!???????????

    • Darsithis

      You and me both. I spent an hour meticulously removing every block and clearing every single red firewall except the final one. Couldn’t find a good way to redirect the beam, so I googled it after another 30 minutes of trying. I saw your comment, placed all 5 in front of the firewall, and boom, firewall down.

    • Ashley Wade

      Omg I love you
      I’m playing on the PS4 but one of the beams isn’t working. I did this and it brought the wall down. Xoxo

    • Dashad mitchell


    • Kazuu

      Can confirm this still works. Thank you!

    • Guest Star

      Still works. I was 1 short on relay decoder to direct the beam to the last firewall, came here to see how many relay decoder in total in this puzzle and if I was missing 1. Tried this method in frustration (not proud of it)

    • Charlene Michelle

      Works! OMG

    • Charlene Michelle


  • John

    I have the laser firing past the last door, but I have no more decoder relay blocks, and you can’t take any from previous positions or the laser stops completely. What do I do?

    • fallout4_m8

      OMG thanks i spended 30 minutes colleting everything and it didnt work i tried the thing with the lasers and i only took 1 minute

  • James Vincent

    If I wanted to play Minecraft or Portal–I would have played them and not fallout 4.

    • Nipple

      Cry about it you inbred fuck

      • Johnny Randall

        You’re a fucking troll. You’re mother should have swallowed

  • Un-Popular Opinions

    If people honestly need a guide for these “puzzles”… I feel bad for you. Perhaps some brain training games would help.

    • OrderedChaos420

      For someone who is looking at the solution to the puzzle you sure are talking a lot of shit. I suppose you googled how to solve the puzzle right after you solved it on your own just to mock all the people who did.

      • Un-Popular Opinions

        Eh. I was actually looking to see if there was a quest line that allowed you to clear the fog out completely, or near enough.
        Since that returned no results, I decided to see what other people were talking about.

        These “puzzles”, while time consuming, do not take much brain power to solve. Looking up the answer is just a waste of time… and makes you look moronic in my book. Yes, I am an asshole. #DealWithIt

        • PCZero

          The last one’s a bit borked because it’s very misleading in the way it’s laid out. It requires you to ignore what would of been a valid solution in a previous stage because suddenly the laser doesn’t go through blocks that it could pass through in the previous puzzle, combined with a rather deceptive layout.

          That said, the puzzles are primarily super simple. All one needs to figure out the fifth puzzle with ease is the simple hint that the middle pyramid with the laser source is a red herring when it comes to opening the final firewall and you actually need to curve the beam around the edge of the stage, not the pyramid.

          Other than that, it’s pretty easy. But it you haven’t done the puzzle yourself without prior hints, it’s kind of silly to make the statement that brain training games would help. The main issue is lack of consistency in the mechanics more than anything. That and too many unnecessary pieces, which generally eat up your time more than anything, as you end up collecting them thinking they’re necessary when they are simply not.

  • Ruben

    Need help here, the boxes to pick up, (lighter shaded cubes) to plant aren’t highlighting to move or store, it’s very frustrating and can’t get anything done. I am
    Not sure if this is one of a few bugs in the new expansion but I am
    Not enjoying this

    • iron

      Same problem.

  • Jamie Phillips you get the turrets to shoot the block job done 3 mins

    • Nicholas

      I just did it thank you lol

  • Chris L.

    I had to LOL at all the people (including the guide poster) who do all this “collect all the blocks” stuff to make all these bridges – you only need two or three blocks to get from one platform to the next (it’s easier with three) just walk out, turn around, grab the block behind you, walk up, place, repeat… when you get to a platform and set up the relay, just jump off, and get reset back to the start – no need to bother with making your way back. Also, once a block is placed, the block holding it up can be re-used, so you only need two blocks to get the relay 3 or 4 blocks high.
    Be sure to use your scroll-wheel for near/far positioning of the blocks.

    (FWIW, I came across this because I thought I’d figured the puzzle out but seemed to be short one relay – I didn’t notice the one all the way on the top to the right)

  • Ryan Owen

    I’m on memory puzzle 1 I have 80% of memory retrieved now my bugs just sit inside the orange one doing nothing is any one else had this problem and how can I go about fixing this I don’t want to load the game back because its to far there must be a solution

    • Marissa Worley

      I’m having this same problem! Would love to know the solution :(

      • Dashad mitchell

        Try loading a previous save I’ve had the same problem

      • Ryan Owen

        I had to load a last save and I had done a lot had to do it all over again worth it tho

        • Marissa Worley

          No way am I loading a previous save; I’m at least 12 hours of gameplay past this.

          • PCZero

            move a turret

  • Aaron Patrick Policoff

    Have an ulcer after that challenge…..mission accomplished.

  • Kris

    Great guide, thanks so much!!!!

  • Number 16

    So this is what now Fallout games are all about..

    • PCZero

      No, it’s a 30 minute mini-segment in a 20+ hour dlc.

  • Twest

    I’m still stuck on fucking puzzle 5!!!!

  • Sharron Curry

    Question plz…..I had to quit on the last puzzle and get some sleep! When I tried to go back to the puzzle all I have is a black screen, ugh! Have I screwed up and can’t solve the last one?

  • joop

    Question, when i start puzzle 5 on the terminal and can,t walk like in the outside whats wrong?
    is there anyone who knows what to do?
