Chains of Duty: Heroic Heavy Bolter
HeavyPairs the Heroic-tier Chains of Duty Heavy Bolter with stacked ranged and health damage reduction to turn the Heavy into a frontline anchor. The Heroic variant fires at maximum rate from the first trigger pull and gives a 50% wider fencing parry window, so the class's classic melee weakness disappears. Hover at low health and ammo on purpose to keep proccing Adamant Restoration and Conviction.

Instant max-rate Heavy Bolter burst, +15% Heavy Might, +15% Brute Force, +25% Discipline stack at low ammo
Survivability
25% squad-wide ranged DR (Encompassing Aegis), 25% health DR on armour break (Conviction), +30% HP pool (Fortitude)

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.
Heroic-tier Heavy Bolter variant and the entire reason this build works. Skips the Heavy Bolter's usual spool-up so the first trigger pull is already at maximum fire rate, and the exclusive Reinforced Guncasing perk widens the perfect parry window by 50% and fully cools the gun after every Gun Strike. That combination patches the Heavy's two biggest weaknesses (slow time-to-damage and weak melee defense) on a single weapon.
How to Obtain
Combat Strategy
- ▸Enter Heavy Stance the moment you engage so Heavy Immunity (no Heavy Hit interruption) and Heavy Might (+15% damage) are live before the first shot lands.
- ▸Pre-position inside the squad's 10-metre cone so Overwhelming Power's +10% ranged damage buff lights up the team the moment Iron Halo deploys.
- ▸Confirm Chains of Duty is the active primary. Reinforced Guncasing is what makes the parry-Gun Strike-reset loop work, and it does not exist on any other variant.
- ▸Open the fight with a full-rate Bolter burst from the first trigger pull. Instant max fire rate is the entire point of the Heroic variant.
- ▸Fire until heat builds, then perform a Gun Strike to fully reset the heat bar via Reinforced Guncasing and immediately return to firing.
- ▸Stack Heavy Might, Brute Force, and Discipline by deliberately running into low-ammo territory, where all three multipliers are stacking at once.
- ▸Cycle Consecutive Execution for grenade refunds (Melta Bombs and Shock Grenades) every time you chain 7 rapid kills.
- ▸Activate Iron Halo on cooldown. Overwhelming Power lifts squad ranged damage by 10% while it's up; the moment it deactivates, Brute Force takes over with +15% ranged damage. Buff uptime is effectively permanent.
- ▸Stay inside Iron Halo's 5-metre core so Offensive Capability's damage-over-time aura shreds anything that closed the gap during the buff window.
- ▸Save grenades for the burst window. Consecutive Execution refunds them, so spending freely is correct.
- ▸Hover at low health on purpose. Below 30% HP, Adamant Restoration refunds 25% of your ammo reserve on a 30-second cooldown, and Conviction kicks in 25% health damage reduction the moment your armour drops.
- ▸Restore armour segments by chaining 10 rapid kills for Restoration (15s cooldown). The Heavy Bolter's horde clear keeps the trigger primed for this.
- ▸Reset heat mid-fight with a perfect dodge to proc Perfect Cooling if you can't reach a parry target.
- ▸Abuse the fencing parry window. The Heroic variant widens the perfect parry by 50%, so Warriors, Whip Warriors, and Chaos Spawn melee chains are now safe to bait and counter.
- ▸Swap to Plasma Pistol for charged-shot stagger when the Bolter can't break an Extremis stance fast enough. Vent heat by holstering back to the Bolter so the pistol is always ready.
- ▸Carry Inferno Pistol instead of Plasma for Chaos Spawn runs. Concentrated burn DPS out-trades plasma splash on a single fleshy boss.
- ▸Auxiliary Reload pays out on melee kills against Extremis-tier and higher targets, so bait those kills into a Gun Strike finisher to refund a primary magazine on top of the heat reset.
