Ask anyone who spent a hundred hours wandering the Commonwealth what they remember most, and they might mention the Prydwen flying over Diamond City. Ask them what they actually liked most, and the answer is almost always Fallout 4 Far Harbor. It’s weird. Normally, DLC is just "more of the same," but Bethesda took a sharp left turn with this one. They went to Maine. They brought the fog. And honestly, they fixed the biggest complaints people had about the base game's shallow writing.
The island is a nightmare. It’s radioactive, soggy, and filled with things that want to eat your face. But it’s also the most "Fallout" that Fallout 4 ever gets. You aren't just looking for a kid; you're deciding if an entire ecosystem of people—Synths, cultists, and grumpy fishermen—deserves to keep breathing.
Why The Fog In Fallout 4 Far Harbor Changes Everything
The atmosphere isn't just a visual trick. It’s a mechanic. In the base game, radiation is an annoyance you fix with a quick RadAway. On the Island? It’s a constant, oppressive weight. The Fog defines the culture of the people living in the town of Far Harbor. They’re desperate. They’re angry. They’ve been pushed to the literal edge of the pier by a creeping, glowing mist that brings monsters with it.

You meet Old Longfellow at the Last Plank, and he basically tells you you’re going to die. He’s right. If the Gulpers don't get you, the Fog Crawlers will. These things are massive. They look like prehistoric shrimp that spent too much time in a microwave, and they have enough damage resistance to make a Fat Man look like a toy. It forces you to play differently. You can’t just sprint through the woods. You have to watch the tree line. You have to listen for the clicking.
Then there’s the Children of Atom. Usually, these guys are just cannon fodder in the Commonwealth. In Fallout 4 Far Harbor, they are a fully realized faction with a base inside a literal nuclear submarine called the Nucleus. They aren't just crazy; they’re a legitimate political power on the island. High Confessor Tektus is a piece of work—paranoid, manipulative, and dangerous. But the game lets you join them. It lets you understand why someone would worship the very thing that destroyed the world. That’s a level of nuance the base game’s "good vs. evil" binary often missed.
The Synth Question No One Can Answer
The core of the story revolves around Acadia. This is a sanctuary for Synths who just want to be left alone. It's led by DiMA, a prototype Synth who happens to be Nick Valentine’s brother. Sorta. It’s complicated. DiMA is easily one of the best characters Bethesda has ever written because he’s a massive hypocrite who thinks he’s a saint.
He’s deleted his own memories because he couldn't live with the guilt of the things he’s done to keep the peace. Think about that for a second. He committed atrocities to save lives, then chose to forget them so he could keep feeling like a "good" leader. It’s messed up. It forces you, the player, to ask if a lie is worth a life.
If you bring Nick Valentine along—and you really should, it's basically mandatory for the best experience—the dialogue gets heavy. Nick is struggling with his own identity, and seeing DiMA is like looking into a dark, distorted mirror. The writing here actually respects your intelligence. It doesn't give you a "Press X to be a hero" button. Every ending feels a little bit oily. Even the "peaceful" resolution requires you to be a massive liar and an accomplice to murder. It’s fantastic.
Dealing With the Memory Puzzles
Okay, we have to talk about the "Best Left Forgotten" quest. It’s the part everyone hates. You have to go into a digital simulation to retrieve DiMA’s memories. It’s a tower-defense-style puzzle game inside a VR world. It’s slow. It’s clunky. It feels like it belongs in a different game entirely.
If you're playing on PC, there are mods to skip this. If you're on console, my advice is to just grit your teeth and look up a guide for the final puzzle. Don’t let it ruin the DLC for you. The payoff—the actual narrative revelations—is worth the twenty minutes of frustration moving blue blocks around.
The Gear You Actually Care About
Let’s be real: we’re here for the loot too. Fallout 4 Far Harbor delivers some of the best equipment in the entire franchise.
- The Kiloton Radium Rifle: You buy this from Brother Kane at the Nucleus. It deals ballistic, radiation, and explosive damage if you get the right legendary roll. It’s arguably the best all-around weapon in the game.
- Marine Combat Armor: Forget Power Armor for a minute. This is the strongest non-power armor in the game. It looks like something a futuristic Navy SEAL would wear. You get it by completing those annoying memory puzzles, which is the "carrot" Bethesda dangles to make you finish them.
- The Striker: It’s a Fat Man that shoots bowling balls. It’s ridiculous. It’s impractical. It’s hilarious when you headshot a Trapper with a Brunswick pro-roll.
- Atom’s Judgement: A super sledge with glowing green fusion cores strapped to it. It deals massive radiation damage. It’s the ultimate "bonk" weapon.
The enemies require this gear. Anglers spit fire. Trappers—human raiders who have lost their minds to the fog—are way better geared than the bandits back in Boston. They use harpoon guns. Have you ever been hit by a harpoon? It hurts.
Making the Hard Choices
The finale of Fallout 4 Far Harbor is a three-way standoff. You have the town of Far Harbor, the Synths of Acadia, and the Children of Atom. You can wipe out any of them. You can wipe out all of them.
If you tell the people of Far Harbor that DiMA replaced one of their own with a Synth, they will form a lynch mob. It’s a brutal, uncomfortable scene to watch. Or you can help the Children of Atom achieve "Division" by nuking their submarine. Or you can use the wind turbine kill switch to let the Fog consume the town.
The "best" ending is the most morally gray one. You replace High Confessor Tektus with a Synth who is loyal to DiMA. You murder a man and replace him with a robot to ensure the two sides stop killing each other. It’s a peace built on a foundation of corpses and secrets. That is the essence of Fallout. It’s not about being the hero; it’s about choosing which brand of "bad" you can live with.
Actionable Tips for Your Next Run
If you’re heading back to the Island, do these things first. It makes the experience much smoother.
- Level up to at least 25. You can start it earlier, but the enemies have huge health pools. You'll just waste all your ammo on a single Fog Crawler if you're underleveled.
- Bring Nick Valentine. I mentioned this before, but seriously. He has unique voice lines for almost every major interaction. It turns the DLC into a personal story for him.
- Invest in the "Aqueous" perks or Lead Lined armor. You spend a lot of time in the water or near it. The rads add up fast.
- Don't rush the main quest. The side quests in Far Harbor—like the murder mystery in the Vault under the hotel (Brain Dead)—are some of the funniest and most creative missions Bethesda has ever made.
- Collect the Magazines. The "SCAV!" magazines on the island give significant buffs that actually matter for high-level builds.
The Island doesn't care about your feelings. It's a cold, radioactive rock filled with people who have every reason to hate you. But that’s why it works. It takes the systems of Fallout 4 and actually gives them stakes. It’s the gold standard for what an expansion should be.

Before you leave the Commonwealth, make sure your storage is empty. You’re going to be bringing back a lot of seafood and a lot of heavy armor. And maybe a bit of a guilty conscience.
