Fallout 4 Puzzles in Best Left Forgotten

Solution to the Memory Game and How to Finish It

Once you access the terminal in the Children of Atom's base, however you did it, you'll have to hack DiMA's old security measures to access his logs. Each log tells a piece of the story which I will not spoil here. These are simply tips for Accessing DiMA's Memories. You'll be put into something similar to Fallout 4's Settlement construction mode, which acts as a kind of reverse tower defense game combined with Portal. You'll be filling gaps so the little data collectors can walk across to the data store, where they will get it in 20% chunks. You can expect resistance once you complete the path, so have defenses to place to bring down the system security. It's very odd, but kind of fun! If you fall off, you will not lose any progress, and if you have to leave it will let you return to the level that you were playing. There are 5 levels in total.

• You may leave and save your game at any time without losing progress. This is handy, as this can be buggy and you may want to get to reload.
• You can store the blocks into the workbench. Do this for every light-colored block you find. That way, you're not taking out a block behind you to fill a gap in front. You want a walkable path from beginning to end, and some parts give you 5-6 blocks at once.
• Rotate blocks using the left/right mouse buttons while holding them when you need to change the direction of a beam that destroys firewalls. On a console, figure out what button rotates and you're good.
• After the second firewall in the first stage, sentries will begin attack your data collectors. It says they require black ice to make, but you have a few already able to build. Deploy them and let them do their work against sentries. These, too, can be placed back into storage so you can drop them any time you need them, or to rearrange them.
• From here forward, when you complete a path, the sentries will begin to spawn. You can have the turrets placed beforehand to save you some time.
• Make note of where the guards spawn, which seems to be a few points (end, mid, entrance) that way they can be under fire soon after and not have time to destroy your little bug guys.
• Place turrets in high positions, so they have a 360 degree angle of attack.
• Fill in gaps that make your indexers have to walk around holes in the 'code'. This makes their trip faster.
• Sometimes the beam is being inhibited by a single block that's in its way and isn't a relay. This can let the beam make it to the firewall.
• The Firewalls sometimes have a weak point. Use a normal code block to extend the area you can place one of the blocks that relay the beam.
• The relay blocks have a green arrow indicating the direction they will send the beam when you're placing them. This helps immensely to avoid trying multiple times for it to go the direction you want.
• Your indexers are infinite - they'll respawn and you cannot fail at this, but you do need to keep trying until you get it right. Good luck!

Level 3-4 Tips to Retrieve Memories

• Don't bother taking turrets down, you can't take anything with you to the next level.
• You always have 5 of the turrets.
• If the weak point is in a hole 3 blocks up, find the block the beam crosses, build 2 blocks up and make the third a relay to bring down the firewall.
• ALL - Explore for supplies. Sometimes they're up on a heap of blocks and that's where you'll find the relay you need. Other times, you need to build to get there.
• Relays connected to bright green blocks will send the beam to another area, along their path. So they're more complex relays.
• Level 3 - You'll need to build yourself a way up in order to access a relay to divert the beam to the correct direction.
• Level 4 - In the area with the massive firewall and a relay block in midair, that relay is one block too high. Build so you can place it as a 2nd vertical block, and turn it toward the firewall. Now use regular code blocks and make it so you can place a relay and hit the weak spot on the right side (facing the firewall). Now you will probably be out of blocks, and the current setup is useless. Store all the blocks. Now, drop down to the lower level and easily place the blocks to redirect the beam to the relay at the beginning of the green line. The firewall is taken care of. I then jumped off to easily go back up, and placed a turret or two then the blocks necessary to let my data miners across.

When You're Done
If you came here for the puzzle, check my page about the Best Left Forgotten Quest and DiMA's Secrets (which mainly implores you to pace yourself) before you go talk to any faction leaders. You learn a lot about the Island's history from DiMA's memories, but I'll write no spoilers here. You can go further and begin uncovering the secrets of the Wind Farm, Nuke Codes, and Avery in Best Left Forgotten Part 2, part of my Endings Guide.
