25 Rare Fallout 4 Weapons That Are Impossible To Find (2024)

Some of the most unique, funny and amazing guns, melee weapons and swords can be found within Fallout 4, but it's definitely not always straightforward how to get your hands on these powerful and rare pieces of firepower. You can survive the Commonwealth with the simplest of weapons, or you can choose to blast your enemies with Nuka-Cola-charged mini-nukes, because why not?

Fallout 4's legendary weapons are often somewhat niche, bizarre, yet most of all incredibly powerful. If you're returning to Fallout 4 now to live out the nostalgia, finding every rare weapon might be one your goals. Moreover, they all definitely change the way you can strategically fight your enemies. Here's where to find these rare Fallout 4 weapons.

Updated June 14, 2024, by Zackary Wiggs: Fallout 4 is still here for you to dive into. With the popularity of the Fallout series and with Fallout 76 gaining more and more players, there's never a better time to hop back into the single-player adventure to the post-apocalyptic Commonwealth. But, you'll need some pretty snazzy weaponry if you want to reach the highest levels as the Sole Survivor. Luckily, Fallout 4 has quite a unique arsenal for you to choose from. You just may need to do some work to get them.

25 The Cryolator

Freeze Evildoer!

Ironically enough, this unique weapon in Fallout 4 can be found at the beginning of the game. However, players may be so focused on getting the hang of their character that they fail to explore the Overseer’s office thoroughly enough.

Return here to retrieve the weapon once you have master lockpicking skill levels. It shoots out cryo-energy much like a flamethrower throws out fire, and freezes enemies in their place. The Cryolator does 20 damage which makes it devastating early on in the game.

24 Lorenzo’s Artifact Gun

Science, Or Something Mystical?

This is a reward for a side quest you happen upon if you visit the Third Rail bar in Goodneighbor. Working for the Cabot family, you eventually discover their secret to immortality and have to end a crazed father attached to an ancient artifact to save the rest of the family.

A week in the game goes by, and the son will let you know he has a unique and rare weapon for you based on the artifact. It deals 28 damage using gamma rounds, which is a fairly good rate compared to other radiation-damage-based weapons.

23 Alien Blaster Pistol

Weapons From Another World

As with all Fallout games, aliens have to come into play at some point. After either reaching level 20 with your character or discovering Vault 75, an alien ship will crash in the Commonwealth.

Start at Oberland Station, and head northeast until you find the crashed ship. Follow a trail to find the alien and a unique Fallout 4 weapon: the Alien Blaster Pistol. It deals 63 damage but uses rare AB rounds, so use it sparingly.

22 Shishkebab

Extra Crispy

There are two ways you can gain this unique melee weapon in Fallout 4. Either you wait until a random legendary enemy drops it or you take on a mission for Abraham Finch, where you recover his family’s sword from Saugus Ironworks, after which you'll get this weapon as a reward.

The mission involves Finch’s son taking the sword to join these raiders, and you can either bring both the son and weapon back, or leave the son to his fate. It deals three damage, and only weighs three lbs, so it won’t take up much of your carrying weight.

21 Kremvh’s Tooth

Straight From The Miskatonic

A very rare and powerful melee weapon indeed, this weapon can be discovered at the very bottom of Dunwich Borers quarry.

Hinting at the series' fascination with HP Lovecraft and Cthulhu mythology, the weapon is found at the bottom of a pool in the caves, after witnessing a vision of cultists from before the bombs fell. Take off any power armor, as you’ll need to swim to retrieve it. It deals 49 damage upon use.

20 Grognak’s Axe

No Shirt Required

One interesting thing about this game is that it seems to have several comic book influences. If you discover Hubris Comics while exploring the Commonwealth or you are given its location when working the Silver Shroud quests, this melee weapon has a damage of 37 per hit.

Based upon the infamous Grognak comics in the Fallout universe, the weapon lies in a glass case near the entrance, but be prepared to fight a horde of feral ghouls to get to it.

19 Furious Power Fist

Get Mad

Another unique melee weapon in Fallout 4, the Furious Power Fist does a damage of 57 per hit, and is more powerful than Grognak’s axe. However, acquiring it will be tricky, as it requires going up against one of the toughest enemies around the area of Diamond City.

Exploring the Boston Commons area, you will discover a location known as Swan’s Pond. There, a behemoth super mutant named Swan will emerge, and you will have to hit him with everything you have to acquire the weapon off its body.

18 Atom’s Judgement

The Nuclear Option

A rare weapon in the Far Harbor DLC, Atom's Judgement is by far the most powerful melee weapon in Fallout 4. Investing in the Nuclear Physicist perk will increase its power thanks to the fusion cells attached to it.

The weapon deals 315 points of damage, and you can find it by completing a Children of Atom quest. However, if you decide to handle it, you must deal with a former member causing trouble named Gwenyth. Once dealt with, Grand Zealot Richter will reward you with the weapon.

17 The Harvester

You Reap What You Sow

This unique weapon comes exclusively with the Far Harbor DLC. A melee weapon, it can be found at the ghoul-infested lumber mill known as Echo Lake. It makes for a great early to mid-game weapon for melee builds.

16 The Striker

No 7-10 Split Here

Found in the Far Harbor DLC, this Fat Man nuclear warhead weapon has a unique twist. Normally this weapon fires mini-nukes and shells out an incredible amount of firepower and radiation at its enemies, but those are hard to come by in the game.

They are rarer than other forms of ammo. However, this weapon fires bowling balls instead, dealing a damage of 275 points. It can be found at the Beaver Creek Lanes in Far Harbor.

15 Nuka-Nuke Launcher

The Other Nuclear Option

A rare weapon in the Nuka World DLC, this Fat Man nuke launcher deals 833 points of damage utilizing special Nuka-Nuke ammo. This makes it an even deadlier version of the already fearsome launcher.

Found after the Cappy in a Haystack quest, the quest’s originator Sierra will direct you to John-Caleb Bradberton’s office in the park. There you will discover him alive, barely, after all these years. If you agree to take him off life-support, he will direct you to a secret vault of weapons, including this one.

14 The Problem Solver

No Problem Too Complex

Obtaining The Problem Solver involves getting on good terms with the leader of a wild group of raiders. A rare weapon in the Nuka World DLC, the weapon deals 21 points of damage utilizing 7.62 ammo. However, this weapon is unique in that it doesn’t require purchase or completing a quest.

Instead, you get this weapon by passing a charisma check with the character Mason, who gives it to you if you pass during the 'An Ambitious Plan' quest. Make sure to pick all the most aggressive dialogue choices when speaking with him.

13 Cito’s Shiny Slugger

Dazzle Them

A powerful and unique melee weapon discovered in Nuka World, Cito’s Shiny Slugger is a modified melee aluminum baseball bat with metal spikes and rockets attached to the weapon. It deals 56 points of damage and can be found after completing the quest Safari Adventure.

12 Eddie’s Peace

Peace Was Never An Option

Discovering him alive in a secret chamber, you take out Eddie together, gaining Nick’s loyalty and this weapon, which deals out 84 points of damage using .44 ammo. Plus, it comes with a short scope attached to it from the get-go.

11 Justice

I Am Justice

This weapon seems simple enough to obtain. A special shotgun that deals 78 points of damage, it can be found near Covenant. The easy-to-find shotgun shells make this weapon a great choice for most levels in the game.

You can purchase the weapon from the town’s store owner named Penny. However, due to the nefarious backstory of the town, there’s a chance Penny might be taken out in the game. Purchase the weapon before completing the quest for this town, otherwise, the weapon will be lost forever.

So Nice He Made It Twice

9 The Gainer

Unleash Your Inner Dirty Harry

This is one of the few instances in the game where it’ll take equal amounts of brainpower to acquire this weapon (as well as brawn). To acquire this powerful weapon, you’ll need to head to the Vitale Pumphouse, where you will have to solve a puzzle with the combination of 10-4-5-1.

The Gainer will be lying on the floor next to a skeleton. It deals 60 hits of damage utilizing .44 ammo. It’s considered one of the more powerful handguns in the game, although at the disadvantage of a six-round cylinder.

8 The Last Minute

The Nick Of Time

During the game, most players will immerse themselves in the world of the Minutemen, local militia soldiers helping the average citizen survive the Commonwealth. As the appointed general of the group, you will help retake their stronghold known as The Castle from a Mirelurk infestation. Later, a seasoned soldier named Ronnie Shaw will ask for help gaining access to the old armory, during the quest Old Guns.

6 Prototype UP77 “Limitless Potential”

Unlimited Power?

A very rare Fallout 4 weapon indeed, this energy weapon is tough to find. It deals 18 hits of damage using energy cell ammo rounds, and to obtain it, you have to get past an army of synths at University Point until you find the student credit union.

Using a side door that leads to a bank vault, you’ll have to hack a novice terminal, then lockpick a master locked safe on the second row of the vault. That will allow you to hit a button that reveals a secret room, where the weapon will be waiting.
