Best Fallout 4 DLCs to Get on Steam Ranked

Fallout 4 might be turning heads again in 2025 thanks to its Steam Deck compatibility, modding renaissance, and constant discounts—but let’s not forget what helped give this game its second wind: the DLCs. Expansions in Fallout 4 aren’t just cosmetic fluff. They reshape gameplay, rewire narrative arcs, and retool the way players experience the Commonwealth and beyond.

So, if you’re about to pick up Fallout 4 on Steam, or already have it and are thinking about expanding your horizons, here’s your ultimate guide to the best Fallout 4 DLCs ranked, from essential to optional—but still fun.

And for those ready to jump in now, you can buy Fallout 4 Steam CD Key at RoyalCDKeys for less than what you’d spend on lunch.

1. Far Harbor

Why it’s #1: If Fallout 4 has a masterpiece in its DLC lineup, it’s this one. Far Harbor introduces a fog-drenched, Lovecraftian island off the coast of Maine that’s equal parts eerie and immersive. Think coastal mystery with branching storylines, high-stakes moral choices, and synth politics taken to the next level.

Highlights:

• Largest landmass in any Fallout DLC
• Dense atmosphere with new creatures like Fog Crawlers
• Introduces new faction tension between the Children of Atom, Acadia, and Far Harbor settlers

Gameplay Impact: This is a full-blown RPG expansion—not just more guns and armor. It rewards exploration and replayability, with serious philosophical weight packed into the narrative.

2. Nuka-World

Why it’s #2: If Far Harbor is Fallout’s noir thriller, Nuka-World is its post-apocalyptic amusement park gone off the rails. You’re not just a visitor—you’re the Overboss. That’s right, you get to lead raiders and reshape how you interact with the Commonwealth.

Highlights:

• Fully explorable theme park zones (think Galaxy Zone, Safari Adventure, Kiddie Kingdom)
• Raider faction control system
• New weapons, power armor, and a morally grey sandbox

Gameplay Impact: You get an entirely new power fantasy: becoming a raider boss. Whether you embrace the chaos or manipulate it for your gain, this DLC flips the script on Fallout 4’s original morality.

3. Automatron

Why it’s #3: This is where you build your own robot army. Automatron brings customization to the forefront, letting you assemble, mod, and fight alongside robot companions. It also introduces the mysterious Mechanist and a tightly woven mini-campaign.

Highlights:

• Deep robot crafting system
• Fun, linear story with satisfying boss fights
• Sparks creativity with mix-and-match robotic parts

Gameplay Impact: While not the longest DLC, it adds tools that remain useful the entire game. And who doesn’t want a robo-butler with miniguns?

4. Vault-Tec Workshop

Why it’s #4: More of a builder’s toolkit than a narrative expansion. But for settlement fans? Pure gold. This DLC gives you your very own vault to customize from scratch—and with it, a ton of new mechanics to experiment on dwellers (ethically or otherwise).

Highlights:

• Build and manage your own vault
• New population experiments and morality choices
• A trove of vault-themed decor and construction items

Gameplay Impact: If you enjoy the settlement building side of Fallout 4, this DLC is a must-have. It’s less story, more sandbox.

5. Contraptions Workshop

Why it’s #5: This one's for players who live to tinker. Contraptions Workshop doesn’t add narrative but turns your settlements into playgrounds for automation, logic, and Rube Goldberg-style machines.

Highlights:

• Conveyor belts, manufacturing lines, logic gates
• Weapon and armor manufacturing
• Fireworks and other flair to show off your base

Gameplay Impact: Highly niche. If you’re into logistics and engineering, you’ll get dozens of hours here. Otherwise, it’s more of a novelty.

6. Wasteland Workshop

Why it’s #6: The smallest of the DLCs, Wasteland Workshop adds features to capture, tame—or pit—wasteland creatures and settlers against each other. It’s light on story, heavy on spectacle.

Highlights:

• Build arenas and fight cages
• Capture Deathclaws (yes, really)
• Neon signs, new furniture, and design options

Gameplay Impact: Fun for those who want to turn their settlements into arenas or zoos. Not essential, but it’s a quirky touch.

DLC Comparison Overview

Instead of a table, here’s how these expansions compare:

• Most Story-Rich: Far Harbor
• Most Sandbox Potential: Vault-Tec Workshop
• Most Combat-Driven: Automatron
• Most Visually Unique: Nuka-World
• Most Customization: Contraptions Workshop
• Most Fun for Settlers: Wasteland Workshop

If you want it all, the Game of the Year Edition bundles every DLC into one package. Combine that with a good deal, and you’re set. Better yet, check RoyalCDKeys for Fallout 4 Steam CD Key prices that often undercut Steam.

When to Buy the DLCs on Steam

• Steam Summer Sale (June/July)
