As part of the main quest in Fallout 4’s Far Harbor DLC you will be tasked with hacking into DiMA’s old memories. These are located inside the Children of Atom base and present a new gameplay mechanic in Fallout 4.'; document.getElementById("serge_648ac998c20ba86b43957c42").style.display = "block"; } There are these five bug like creatures that need to go to the memory retrieval point and back to the starting point. The way between these is blocked by red force fields or there is no road they can cross. You have an interface similar to the workshop screen where you can build three things – regular code blocks (used to build paths), Defense constructs (you get 5 of these turrets to defend against security) and decoder relay (used to redirect the light beam that breaks down red force fields). Your task is to construct roads with code blocks, redirect the light beam to destroy red force fields blocking the path and at the end secure the path so the little bugs can safely retrieve data to the starting point. In this guide we’ll provide you with a video showing solutions to all puzzles and some detailed explanations on how to solve some of the harder parts.

Memory retrieval puzzle tips

The first thing you should be aware of is that the puzzle solving works like building in your settlement. This means that you can store Code blocks, turrets and relays. This is extremely helpful later on because you can store your stuff from one place and use it in another. I recommend you just store every block you come across and when you are sure what and where you need to build you start building with stored blocks.

Keep in mind that you can also rotate the placement of decoder relays with your right mouse button to direct the beam in the direction you need it to go.

Defending the little bugs once they start retrieving data is easy. Red security attackers spawn at two places on the map. Make sure you place at least two turrets near their spawning points. This should help protect your guys throughout their journey.

The main problem is finding a way to redirect the light beam to destroy all red force fields blocking the path of your little friends. Make sure you explore the whole puzzle and look vertically as well, because solutions are mostly on different ground levels than where you start at.

Memory puzzle 5 solution – 0Y-8K7D

The only puzzle that is a real challenge is the fifth (last) one. Zone is much larger and you need to figure out how to get rid of all the force fields and how to place the relays to get the beam to remove the last force field protecting the core. First make sure you pick up and store any and all code blocks at the start. You will need them to build paths. Images bellow shows the path you should be taking as you solve the puzzle.

1. Go to the central structure and store all code blocks and a relay into your workshop inventory. Now put up three code blocks and a relay facing left under the light beam to unlock the structure to the left.
2. Build a bridge to over there and pick up code blocks and a relay.
3. In the middle put another three blocks and a relay facing straight (away from where you started and the end is).
4. You can build a bridge to the structure behind to pick up extra code blocks (you need to do this to have enough). Make sure you pick back up the code blocks you used to build the bridge.
5. Build a bridge to the little island top left and make the code block pillar and relay redirecting the light beam towards the right side of the room.
6. Build a bridge to the furthest central structure. Pick up all the code blocks there to free the way for the light beam.

7. Go back to the beginning and create a bridge to the structure to the right. Pick up the relay and also jump up and climb until you reach the upper floors of the right hand structures. Pick up all the code blocks you can.
8. Inside the central right structure build a small sideways block and attach the relay sideways so you remove the force field in the bottom right structure.

9. Now build a bridge to get the relay on top of the bottom right structure and jump down to get the relay you just freed from the force field.

10. The hard part is this. Go to the central right structure and drop down to where the light beam comes out.
11. Build a pillar here that is 6 blocks high and attach a relay that will redirect the light beam in the direction of the final force field.
12. Build another pillar and relay to redirect the light beam towards the final force field.
13. Back at where you started put another relay that will finally unlock the end point.
