Warhammer 40,000: Dark Imperium (2017), p7 — Plague Marines

No Traitor Legion stands as high in Nurgle's favour as the Death Guard. Swollen with the Plague God's blessings and utterly devoted to the corruption of realspace in his name, the hulking Plague Marines that comprise their mainstay despoil all in their path while chanting praise to their gruesome patron.

Plague Marines are relentless and deadly warriors, whose apparent plodding nature belies their lethality. The traitors' advance is slow but inexorable, and almost impossible to stop with anything but the heaviest weaponry.

Decaying within their armour, Plague Marines' bodies have long since become immune to pain or fatigue. Their living flesh fuses directly with their Chaos-twisted power armour, forming a disgustingly resilient whole. Blasts and bolts may crater the Plague Marines' bodies, but few will do more than slow the traitors down and splatter their tainted blood across friend and foe alike. Those who plunge blades or claws into the Plague Marines' forms will be fortunate to do any sort of meaningful damage, and may well find their weapons trapped between sucking folds of rancid fat.

In return, the Plague Marines' every blow is delivered with clubbing strength, their every shot well placed and explosively deadly. Grime-encrusted bolters roar as they spew volleys of self-propelled bolts into the enemy, mowing them down like corn before a scythe. Foul plague knives are driven into the foe, the seething toxins that befoul the blades turning flesh black with rot and clotting blood into sludge. Blight grenades loop end-over-end through the air, bursting in great showers of pathogenic spores and putrescent slime.

Like a ponderously swung sledgehammer, the Plague Marines drive unstoppably through the enemy ranks, their rusted boots grinding flesh and bone as they catch the foe in expert fire-spreads and relentless, overlapping advances. The Plague Marines chuckle wetly through clogged vox grills, flies buzzing in choking clouds about them as they bring Nurgle's wrath to their foes.
