Best Starter Heavy
HeavyThe full-tank Heavy, built on the one Heavy weapon that fixes the class's biggest weakness. Every other Heavy primary is locked to a Balance parry window, but the Chains of Duty Heroic Heavy Bolter has a Fencing window, which makes melee survivable rather than terrifying. Heavy Immunity then grants no-knockback in heavy stance, which frees you from Strategic Stance entirely and lets the whole perk tree go into bulk. Stack Fortitude, Adamant Will, Encompassing Aegis, and Conviction and you end up tankier than most Bulwarks, without giving anything up, because the Heavy gets there for free. The Iron Halo trick underneath it all is the clever part: activate it and immediately turn it off, and Adamant Will's damage reduction stays up permanently.
Damage
High and sustained. 30% from Heavy Might in heavy stance, plus a stacked 25% from Brute Force and Overwhelming Power running simultaneously
Survivability
The highest in this build set. Fortitude 30% health, permanent 20% from the Adamant Will cycle, 25% ranged reduction from Encompassing Aegis, and Conviction on top
Boss
Strong. Sustained Heavy Bolter fire with stacked damage buffs holds up well against Extremis and boss health pools
Heavy
The walking weapons platform of the Space Marine 2 roster. The Heavy mounts the squad's biggest guns, projects an Iron Halo aura that absorbs ranged fire for the whole team, and trades mobility for the ability to anchor a position and shred Tyranid swarms or Chaos elites with sustained fire.
One of the two best Heavy weapons in the game, and the easiest to use by a wide margin. Every other Heavy weapon is permanently locked to a Balance parry window. This one has a Fencing window, which is the entire reason it is the starter pick: it converts the class's classic melee weakness into something manageable. It also picked up the Patch 13 Bolter buff giving 30% more body shot damage.
How to Obtain
Combat Strategy
- ▸Confirm Heavy Immunity is slotted. The entire full-tank plan depends on skipping Strategic Stance.
- ▸Take Field Adjustment and Adamant Will together. Neither is worth much here without the other.
- ▸Choose the final class perk: Offensive Capability for Chaos-heavy runs, Conversion Field for cooldown reduction.
- ▸Hold heavy stance and lay down sustained fire. Heavy Might adds 30% damage while you are in it.
- ▸Cycle the Iron Halo on and immediately off to keep Adamant Will's damage reduction permanently active.
- ▸Because the Halo reads as on cooldown while active, Brute Force and Overwhelming Power stack for 25% ranged damage.
- ▸Parry anything that reaches you. The Fencing window makes this genuinely reliable.
- ▸Activate the Iron Halo before a big engagement so the whole squad gets Overwhelming Power's 10% ranged damage.
- ▸Fire charged Plasma Pistol shots to stagger Extremis targets that close the distance.
- ▸Offensive Capability's Halo damage clears Rubric Marines and cultists outright.
- ▸Restoration returns an armour segment every 15 seconds for killing seven enemies, which happens constantly.
- ▸Encompassing Aegis protects armour as well as health, so it compounds with armour regeneration.
- ▸Charged Plasma Pistol shots are the fastest contested health return in the kit.
- ▸Execute Extremis enemies in melee to trigger Auxiliary Reload and refill primary ammo.
- ▸Skip the last one or two Heavy Bolter damage nodes for Great Might and Increased Capacity if ammo is running short.
- ▸Duelist does not currently function on Balance or Fencing weapons, so do not take it despite the Fencing parry window.
- ▸The Heroic Heavy Plasma Incinerator is a straight swap if you prefer its damage profile, at the cost of the Fencing parry window.
