best left forgotten fallout 4 Complete Quest Walkthrough and Choices

The Far Harbor expansion for Fallout 4 introduces players to some of the most morally complex decisions in the entire post-apocalyptic wasteland. At the center of this narrative is the pivotal mission titled Best Left Forgotten, which tasks the Sole Survivor with uncovering the buried memories of the synth leader DiMA. Navigating this quest requires a mix of patient puzzle-solving and strategic foresight regarding the future of the island's fragile factions.
Navigating the Memory Retrieval Simulation
To begin the extraction process, players must travel to the Nucleus and access a high-tech pre-war computer terminal. Inside this digital simulation, you must direct indexer sprites to retrieve data packets while building paths out of code blocks. The early simulation puzzles focus on simple structural navigation and redirecting security light beams to destroy data firewalls.
As you progress to the fifth and final memory block, the layout becomes significantly more intricate and time-consuming. Players must strategically position code blocks to defend their sprites against active automated counter-measures. Successfully completing this virtual gauntlet rewards you with incriminating audio logs that reveal DiMA's deeply hidden secrets.
Uncovering DiMA's Buried Secrets
The retrieved data files expose several critical pieces of hidden history that alter your understanding of the island's conflict. First, you discover the exact coordinates of a secret medical facility where DiMA replaced a prominent local political figure with a synth double. This covert operation was executed to maintain diplomatic relations between Arcadia and the human settlement of Far Harbor.
Additionally, the memories reveal emergency launch codes for a nuclear missile housed inside the children of atom base. You also uncover the authorization codes to disable the wind turbine array that protects the main civilian dock from radioactive fog. These powerful secrets give the player total leverage over the survival of every major faction on the island.
Evaluating Your Moral Choices and Consequences
Once you exit the terminal, you must decide how to handle the shocking truth regarding the replaced prime captain. You can choose to confront DiMA directly in Arcadia, allowing him to explain his utilitarian motives for the murder. Players can then convince him to turn himself in to the citizens of Far Harbor, which often leads to his immediate public execution.
Alternatively, you can choose to keep the secret hidden to preserve the peaceful status quo among the distinct communities. Deciding to share the launch codes or the turbine override will lead to the complete destruction of the respective factions. Choosing a diplomatic path requires immense careful balancing but yields the most stable long-term resolution for the commonwealth region.
