GW revealed a new way to arm your Space Marines with the Horus Heresy melee weapons upgrade pack, featuring chainswords, power weapons, and more.
Horus Heresy Melee Weapons Upgrade Pack: Equip Your Space Marines for Ultimate Carnage
Horus Heresy—where brother fights brother, galaxies burn, and no one is safe from betrayal. In this grim age, every self-respecting Space Marine knows that bludgeoning someone with style is half the battle. Enter the latest Legiones Astartes Melee Weapon upgrade pack, a kit so packed with sharp objects and grim relics of war that even Angron might nod in approval.
Let’s take a stroll through this arsenal. It’s not every day we’re treated to a bit of this hefty cache of destruction.
10 Chainswords
Who doesn’t love a chainsword? There’s nothing quite like revving a motorized, serrated blade and bringing righteous fury to the battlefield. These ten beauties are ready to slice through traitors like they’re made of parchment. Each chainsword, forged in the blood-soaked history of the Great Crusade, is the kind of tool every aspiring hero (or anti-hero) needs to survive the grind of war. Plus, the whirr of the teeth as they carve through ceramite and flesh? Now that’s music to the ears.
Two Chainswords in Sheathes
For the warrior with a penchant for style and subtlety, these sheathed chainswords add that extra touch of menace. You’re not swinging them yet, but oh, you will—and when you do, the last thing your foe will hear is the click of the sword leaving its scabbard before everything goes black.
Two Heavy Chainswords
Because sometimes, a regular chainsword just doesn’t scream, “I mean business.” These hefty monsters are the answer when you want to leave nothing but red mist behind. Heavy chainswords are what you grab 
When you’re tired of close calls and want your opponent in pieces before you even finish that war chant.
Two Charnabal Sabres
For the more refined killer, these sabres are elegant, vicious, and steeped in the tradition of noble duels. Their sharp, wicked curves are designed to dispatch foes with finesse, perhaps reminding some of those ill-fated warrior kings of Old Terra, who lived and died by their blades.
Two Thunder Hammers
What’s more satisfying than a chainsword? How about a hammer that cracks tanks like eggs? Thunder hammers are the perfect tool for Astartes who appreciate the art of overkill. Whether you’re smashing apart power armour or, you know, turning a Titan’s knee joint into paste, these bad boys get the job done with the subtlety of a meteor impact.
Four Power Swords
Power swords: classic, reliable, and capable of cleaving through just about anything. Two drawn, two sheathed—ready to ignite with a field of energy that can slice through even the toughest armour. These relics of war remind us that sometimes, the old ways are still the best ways.
Two Power Lances
Looking to strike down a foe with speed and precision? Power lances are your answer. Perfect for lightning-fast charges, they’re reminiscent of the cavalry lances of old, only, you know, charged with enough energy to make an ork warboss sweat.
Four Power Axes
For the Space Marine who prefers his enemies in chunks rather than halves, power axes offer just the right balance of brutality and elegance. Whether chopping through an opponent’s armour or a Traitor Legionnaire’s neck, they’re reliable and devastating.
Four Power Mauls
Power mauls are for those who enjoy the “blunt force trauma” method of combat. You don’t just want to kill your opponent—you want to pulverize them, leaving nothing but a crushed ruin in your wake. They bring a certain primal satisfaction, don’t they?
Four Power Fists
Sometimes, you just need to punch a tank. Enter the power fist. These massive gauntlets amplify a Marine’s strength to catastrophic levels, making them ideal for those situations where only a crater will suffice.
Four Claw Assemblies (for turning Power Fists into Lightning Claws)
Need to spice up those power fists? Just attach these claws, and suddenly your tactical brute has transformed into an apex predator, ready to rip and tear through anything unlucky enough to stand in their way.
The Bonus Gear
But wait, there’s more! Augury scanners for spying on distant threats, melta bombs for turning enemy vehicles into smoldering wrecks, and a whole host of pistols and bolt weapons that prove your Space Marines mean business, even at range. Flamers, plasma pistols, volkite serpenta—this kit doesn’t just equip you for battle, it gives you the tools to annihilate.
Whether you’re building a squad of veteran warriors or outfitting your Despoilers for the next brutal melee, this upgrade pack provides an array of weapons to keep your enemies guessing—and bleeding.
Final Thoughts on the Horus Heresy Melee Weapons Upgrade Set
So there you have it—a collection of weapons that could make even the Primarchs pause and take notes. Whether you’re a newcomer just starting to kit out your first squad or someone who’s been battling through the Horus Heresy since the days of Rogue Trader, this upgrade pack has a little something for everyone. Chainswords, power weapons, thunder hammers… you name it; this set turns your Space Marines into walking arsenals of destruction.
