Ultimate Heavy Build Guide for Space Marine 2: Weapons, Perks, and Gameplay Tips

Space Marine 2’s Heavy build is perfect for taking down bosses like the Carnifex and Hellbrute, and it’s also effective in multiplayer. Here’s how to craft this powerful build.

Players familiar with the Warhammer 40K tabletop game will recognize the Heavy Marine loadout as the classic Devastator Marine. Though the term isn’t used in the game, this setup can be employed in the story campaign, Operations, and PvP modes. The build emphasizes the use of heavy weaponry while minimizing melee combat.

This guide will help you assemble the Heavy build to blast Tyranids, Chaos forces, and PvP opponents into pieces.

Hellbrutes are corrupted Space Marine Dreadnoughts that can be defeated with heavy weaponry.

Best Weapons Explained

Primary Weapon – Multi-Melter

The Multi-Melter is an extremely powerful weapon.

While you can utilize multiple perks, these are the best for the Multi-Melter:

Perk	Description
Increased Capacity x2	The maximum Ammo Reserve of this weapon increases by 20%
Heavy Immunity	While in Heavy Stance, you do not lose control from heavy hits
Executioner’s Fire	After a finisher, fire rate increases by 25% for 5 seconds
Heavy Might x2	Killing an enemy restores armor 0.5 seconds earlier
Fast Regeneration	Killing an enemy restores armor 0.5 seconds earlier
Chaos Eliminator	Damage against Chaos enemies increased by 10%
Tyranid Eliminator	Damage against Tyranid enemies increased by 10%

These perks will maximize your damage against enemies from a distance while ensuring your armor stays replenished. We’ve also optimized for perks that assist with ammo capacity, increase the fire rate, and maintain your stability during combat.

Secondary Weapon – Bolt Pistol

The Bolt Pistol perfectly complements the Heavy build. Equip the following perks for maximum efficiency:

Perk	Description
Great Might	Damage increases by 10% against Terminus enemies.
Retaliation	After a perfectly timed Dodge, you deal 25% more damage for 5 seconds.
Gun Strike Reload	After a Gun Strike, the equipped weapon instantly reloads.
Perpetual Precision	Maximum Spread decreases by 10%.
Head Hunter	Headshots deal 10% more damage.
Elite Hunter	After killing a Majoris-level or higher enemy with a melee weapon, headshots deal 50% more damage for 5 seconds.
Extended Magazine	Magazine size increases by 15% of the maximum.
Divine Might	Damage increases by 10%

While the Bolt Pistol serves as your backup weapon, these perks enhance its lethality. Ensuring it reloads instantly, increasing damage, and boosting ammo capacity makes it more formidable in combat.

The Elite Hunter and Retaliation perks also transform the Bolt Pistol into a powerful tool when used in combination with other abilities, allowing it to significantly contribute to your overall damage output.

Best Grenades for Heavy – Melter Bomb

Adopting this build turns you into a relentless battle tank rather than a quick-hit rogue-type Marine like the Vanguard build. Therefore, you’ll need an explosive option that matches this style.

Melter Bombs are perfect for this build; you can place them strategically, get into position, and detonate them when enemies approach, effectively thinning their ranks. While frag or krak grenades can be utilized if you run out, Melter Bombs should be your primary offensive choice.

The Heavy Build is inspired by the classic Devastator Space Marines.

Best Perks for Operations

In PvP, you may choose a grenade, but in Operations, character perks come into play, allowing you to create a powerful version of the Space Marine. Focus on the following perks for the Heavy build:

Perk	Description
Thermal Boost	When a ranged weapon is 50% overheated, damage increases by 15%
Restoration	Killing 10 enemies quickly restores 1 armor segment
Multi-Kill	Killing 5 or more enemies with a Multi-Melter restores ammunition by 1
Auxiliary Ammunition	When your primary weapon is out of ammo, killing 10 enemies quickly restores ammo.
Fortitude	Health increased by 20%
Overcharge	Damage of Charged Attacks increases by 20%
Encompassing Aegis	All squad members take 20% less damage from ranged attacks
Offensive Capability	When active, Iron Halo deals damage over time to all enemies within 5 meters
Overwhelming Power	When Iron Halo is active, all squad members within 10 meters deal 10% more ranged damage

These perks boost your damage output, enhance the effectiveness of your Iron Halo, and improve overall defense in terms of health and shields. The buffs from Iron Halo also extend to your teammates, making the Heavy build an excellent choice for cooperative gameplay.

Key perks that replenish ammo passively serve as a major advantage. The Multi-Melter ammo can deplete quickly, and these perks help to mitigate the risk of being caught without it.

How to Play the Heavy

This build emphasizes ranged firepower over melee combat. Focus on moving and gunning with your Multi-Melter. The strategy is to allow enemies to advance and then incinerate them with melter rounds.

You can still perform executions, which will be essential for replenishing your armor or quickly dispatching groups of Termagants. For long-range encounters, switch to your Bolt Pistol, then return to your Multi-Melter when the opportunity arises. Pay attention to ammo crates, as your Multi-Melter consumes rounds rapidly.

If you’re familiar with the tabletop game, envision yourself as part of a Devastator squad while using this build. Sit back, relax, and incinerate the Tyranids. Don’t hesitate to experiment with different weapons, keeping in mind that your perks are centered on the Multi-Melter.
