You can get them by killing unique enemies (and looting their bodies), or by finishing quests. This guide will show you the best unique and rare weapons in Fallout 4, where to find them and what they do.

Salvaged Assaultron Head

Type: Energy Pistol
Bonus: Charged by reloading repeatedly. The more charges, the higher the damage. Irradiates user.
Location: This weapon was introduced in the Automatron add-on. You’ll find it in Fort Hagen Satellite Array, all the way to the east. When you go down the long, winding stairs, go through the door on your left. The head is in the cage on the right, in a chest. You’ll need to finish the Headhunters quest first (if you’re currently doing the quest, the chest is at the end of the exit route, right before the stairs).

Junk Jet

Type: Junk launcher
Bonus: Uses junk items as ammo, shots can be charged for more damage
Location: The Junk Jet can be found in the basem*nt of ArcJet Systems, in the part of it that’s first accessible during the Call to Arms quest. It’s on a table in the engine control room (the one before the one with the generators), next to the broken concrete wall.

Justice

Type: Shotgun
Bonus: Chance to stagger on hit
Location: This one can be bought from Penny Fitzgerald in Covenant. You’ll have to take a psychological test at the gate to enter, but it seems there’s no wrong answers.

Big Boy

Type: Missile launcher
Bonus: Fires two Mini-Nukes at once
Location: You can buy the Big Boy at the Diamond City Market, from Arturo.

Kellog’s Pistol

Type: Revolver
Bonus: Critical hits refill AP
Location: You can only get it during the Reunions main quest. It’s in Fort Hagen, equipped by Kellog. After you defeat him, loot his body to get the pistol.

Experiment 18-A

Type: Plasma Rifle
Bonus: +25% fire rate, +15% reload speed
Location: This one can be bought from the merchant in the Institute. It’s quite expensive, but also very effective against synths.

Broadsider

Type: Cannon
Bonus: None
Location: You’ll get this cannonball launcher as a reward for doing a relatively long chain of quests to help the robotic crew of the USS Constitution. It uses actual cannonballs as ammo, and we haven’t seen many of those around, but it does great damage.

Deliverer

Type: Pistol
Bonus: Improved VATS hit chance, 25% less Action Point cost.
Location: You will get this pistol during the quest Tradecraft (main quest chain). At the very end of the quest Deacon will whisper to you – Dead guy on the floor. Loot the guy and you’ll get the unique weapon Deliverer.

Short Syringen Rifle

Type: Rifle
Bonus: None
Location: Go to Vault 81, northwest of Diamond City. You’ll have to complete several quests first. After finishing “Hole in the Wall” quest, doctor Forsythe will reward you with this weapon.

AX90 Fury

Type: Gun
Bonus: 50% more damage vs. Super Mutants.
Location: Sold by Teagan, who shows up after completing the main quest Reunions.

The Gainer

Type: Revolver
Bonus: Sets targets on fire for 15 points of damage
Location: The Gainer is in a pump station a bit east from Finch Farm. Go into the building, and follow the corridors until you’ve found a mechanism with four buttons. You should set the numbers above them to 10, 4, 5, 1, by pressing each button a number of times. This will unlock the door to the dead body and the revolver next to it.

Virgil’s Rifle

Type: Rifle
Bonus: +50% damage against super mutants
Location: You can only get this weapon during or after The Glowing Sea quest. Go to the Rocky Cave, south-west of Atom Crater – it looks like it’s outside the edge of the map. It’s a dangerous place, with lots of radiation and a Deathclaw in front of the entrance. Virgil lives in that cave, and you can either steal the rifle from him or kill him and loot it. It works in both his super-mutant and human form.

Cryolator

Type: Rifle
Bonus: Freezes enemies
Location: The Cryolator is in a case with a Master Lock in Vault 111. There’s a glitch that lets you have it without picking the lock, though. Take Dogmeat with you, and when you’re in front of the case, tell him to fetch an item (talk->fetch->items), and he’ll pull it out of the case as if it were lying on the floor.

REBA II

Type: Rifle
Bonus: +50% damage against Mirelurks and bugs, night vision scope
Location: Go to the Rook Family House, on the peninsula in the far north-east. Kill the Mirelurks in the street, then talk to the man on the roof. He’ll ask you to fix some turrets around town, and when you do, he’ll reward you with the REBA II. Don’t think about killing or robbing him – the gun will disappear if you do.

Prototype UP77 “Limitless Potential”

Type: Laser Gun
Bonus: Unlimited ammo capacity (never has to be reloaded)
Location: You’ll find this laser pistol near University Point, on the coast south-east of Diamond City. Go into the bank using the side entrance, then go through the door on the right. Descend into the basem*nt, and go into the bank vault. Open the safe with the Master Lock on it, and press the red button. A secret chamber will open up, and you’ll find the weapon on the table inside.

Grognak’s Axe

Type: Axe
Bonus: Hit cause more stagger, and targets take bleed damage.
Location: Just north-east of Diamond City look for a Hubris Comics building. When you enter the building look to your left, and you’ll see Grognak’s Axe in a locked glass box. You must have the advanced lockpicking skill in order to obtain Grognak’s Axe.

Furious Power Fist Weapon

Type: Melee Weapon
Bonus: Hit cause more stagger, and targets take bleed damage.
Location: In order to get this Melee weapon you have to defeat a huge boss Swan. Head to the Swan’s Pond, it’s to the right of Diamond City. You’ll find him next to the pond. The whole area has a lot of radioactivity. Since the boss is quite strong use Nuka Grenade and Molotov co*cktails to defeat him faster, or drop down mines and lure him into them.

Gamma Gun

Type: Gun
Bonus: None
Location: You can get Gamma Gun on the bottom left corner of the map in Decayed Reactor Site. You’ll need Power Armor, or a Hazmat Suit in this area. You can get Hazmat Suit in the “Hugo Hole” place, on the right side of the map. Inside the crashed dome look for a corpse and loot it. There is a strong mob inside, lure it out before you loot the bead body.

Alien Blaster Pistol


Type: Pistol
Bonus: None
Location: It can be found near Oberland Station, during event Alien Crash Site. This event occurs if you are lvl 14+. Look for a little alien in a nearby cave. Check out screenshot guide for Alien Blaster Pistol.

Overseer’s Guardian

Type: Rifle
Bonus: Shots an additional projectile
Price: 3138
Location: It can be bought in Vault 81 (just left of Diamond City). In order to enter this vault you must have 3 Fusion Cores, so bring them with you. When you enter the vault choose the right path that leads to elevator. From the elevator go right and you will find Alexis Combes in Depo.

Kremvh’s Tooth


Type: Knife
Bonus: Targets bleed and are poisoned. Exceptional damage.
Location: This weapon can be found in Dunwich Borers, on the right side of the map, near Hugo’s Hole. This is a high level area, with numerous mobs, thus be careful. It’s pretty tricky to describe the exact location of the weapon because it’s hidden in an underground pond, and the whole area is radioactive, thus, you have to act fast. We suggest you to watch Kremvh’s Tooth video guide first.

Shem Drowne Sword

Type: Sword
Bonus: Targets take radiation damage.
Location: In Diamond City look for Valentine Detective agency. Take the files from the office, that will trigger the quest The Gilded Grasshopper. It’s a long quest, but at the end it takes you to the graveyard where you have to dig up a grave.
