Helldivers 2 Noxious Strain: How to Kill Noxious Spewers, Scavengers and Cure Poison

Quick answer (updated November 6, 2026): The Noxious Strain is a new Terminid sub-faction that went live in Helldivers 2 on November 3, 2026, running on the current Devoid of Liberty 7.2.2 build. It adds two units: the Noxious Scavenger (tiny, very fast, fragile, poisons on every bite) and the Noxious Spewer (a fast, hulking Spewer that fires a sprint-blocking Web Spit and bursts into a Web Explosion when you pop its unarmored abdomen). Poison comes in two tiers, and Arrowhead says stims help cure it. They knock poison back, but they aren't an instant full reset. To win: bring volume-of-fire weapons (shotguns, flamethrowers, grenades) for Scavengers, shoot Spewers in the abdomen from outside the web blast, and avoid the bites in the first place. The same drop also made bug caves appear on far more biomes.

This guide covers what each Noxious unit does, how the poison system works, how to deal with webs, and the loadout that holds up in the new caves on difficulties 7 to 10. Everything below comes from Arrowhead's official Ministry of Truth announcement on Steam and the PlayStation Blog, checked against what players are reporting in their first three days with the strain.

What is the Noxious Strain in Helldivers 2?

The Noxious Strain is the newest Terminid sub-faction. It sits alongside the earlier ones, like the Spore Burst Strain and the Predator Strain. Arrowhead's announcement opens with the line every briefing now quotes:

"Designated the Noxious strain, these menaces are fast, venomous, and fundamentally opposed to Managed Democracy." (Ministry of Truth, Helldivers 2 Steam announcement, November 3, 2026)

Here's the strain at a glance:

Fact	Detail
Live since	November 3, 2026 (no separate patch note; current build is Devoid of Liberty 7.2.2 from October 29)
Faction	Terminids
New units	2: Noxious Scavenger, Noxious Spewer
New status effect	Poison, with 2 tiers (Lightly / Heavily poisoned) and a new HUD icon
New hazards	Web Spit (blocks sprint), Web Explosion (snares everyone nearby)
Counter	Stims "help cure" it (official); avoiding bites matters more
Paired change	Bug caves can now appear on far more biomes, "from scorched deserts to frozen tundras"

The design idea is simple: take away your mobility, then punish you for it. Webs and heavy poison both stop you sprinting. On bugs, sprinting is how you escape a bad position, so the whole strain is built to make you stand and fight at close range. That's why your loadout matters more than usual on a Noxious planet.

How do Noxious Scavengers work, and how do you kill them?

At a glance a Noxious Scavenger looks like a normal Scavenger. The difference shows once it reaches you. Per the official breakdown, they're "noticeably quicker than their cousins," every bite delivers "a deadly dose of poison," and they're "ready to bite again almost immediately."

The good news is in the same paragraph: they're fragile. Arrowhead says straight out that "weapons that reward volume over precision such as shotguns, flamethrowers, and grenades, will make short work of them." Translated into a practical plan:

• Don't track them with a precision rifle at close range. They move too fast for that to work, and one missed shot means a bite and a poison stack.
• Use spread weapons. The SG-225 Breaker, the SG-8 Punisher and the incendiary SG-451 Cookout all clear a Scavenger pack in a burst or two. Our best shotgun ranking after the 7.2 buffs covers which one fits your playstyle.
• Flame anything that bunches up. The FLAM-40 Flamethrower turns a narrow cave tunnel into a kill zone, and Scavengers are too flimsy to survive running through fire.
• Throw grenades early. A grenade into a pack before it reaches you saves a stim later.

The bigger risk with Noxious Scavengers isn't any single bug. It's the bites adding up. Each bite poisons you, and they bite again fast, so one Scavenger left alive on your flank can push you from Lightly to Heavily poisoned while you're busy with something else. Kill them first, even when bigger targets are on screen.

How do you kill a Noxious Spewer?

Forget everything you know about Spewers dragging themselves across the ground. The official description calls the Noxious Spewer "a hulking monstrosity that moves with unsettling speed," and it's the unit responsible for the webs now covering Noxious battlefields. The community wiki lists it as a variant of the Nursing Spewer, but it doesn't play like one. Players in the reveal thread describe it as able to leap at you "like a hunter" as well as spit and bite.

It has three attacks:

• Web Spit (medium range): "One hit and you lose the ability to sprint." That's the setup for everything else, because it slows you so the Spewer can close the gap.
• Bite (close range): quick, with "surprising reach," and it carries "a stronger dose of venom than anything a Scavenger can deliver."
• Web Explosion (on death, from the abdomen): when its sac bursts, "it will snare every Helldiver and bug nearby."

Where is the Noxious Spewer's weak spot?

The armor layout is the most useful fact in the whole announcement: its head has medium armor, and its web-filled abdomen has no armor at all. So:

• Aim for the abdomen. Any weapon kills it there, light-penetration primaries included. You don't need anti-tank or a medium-pen primary to deal with this unit.
• Kill it at range, never up close. The abdomen burst snares everyone nearby, bugs included. Pop it while it's still at medium range and the web lands on it and any Terminids around it, not on you.
• Use the explosion on purpose. Since the Web Explosion also snares bugs, a Spewer walking into a pack of Scavengers is a free crowd-control tool. Wait until it's in the middle of the pack, then burst it.
• Shoot the head only if you have to. Medium armor means light-pen weapons bounce. If you're forced to fight one face-on, switch to a medium- or heavy-pen option or reposition for an abdomen shot.

One early player report from the reveal thread backs up the precision approach for anyone who'd rather not run shotguns: they found the R-40 Sightliner from the Scope of Authority Warbond killed the new bugs "with one headshot," with the AMW-20 Apex handling the big targets. Treat that as one squad's experience, not an official number, but it lines up with Arrowhead's armor description.

How does poison work in Helldivers 2?

Poison is a brand-new status effect, and it has its own icon on your HUD so you always know your state. Arrowhead splits it into two tiers:

Poison tier	What it does
Lightly poisoned	Your vision starts to haze and the poison "begins to eat away at your health"
Heavily poisoned	Damage over time increases, you lose the ability to sprint, your vision hazes, and (in Arrowhead's words) "Lady Liberty comes to visit you"

How do you cure poison?

Stims are your answer, with a catch. Arrowhead's guidance: "your stims will help cure your condition, so ration them wisely." Note the wording, "help cure." The community wiki's status-effect breakdown says a stim strips poison build-up rather than wiping the effect instantly, so poison already ticking can keep hurting for a moment and your sprint may not come back the second you inject. Treat a stim as damage control, not an undo button.

One player in the reveal thread summed the strain up as "just a stim-tax subfaction," and that's the right mindset for planning. Your stim economy is your health bar now.

Practical rules that follow from it:

• Stim early, not late. Because a stim knocks poison back instead of resetting it, stimming as the poison builds keeps you out of the Heavily poisoned tier, where you lose your sprint. Waiting until you're already heavy means fighting slowed for a while even after you stim.
• Avoiding bites beats curing them. Kill Scavengers before they reach you and pop Spewers at range. Every bite you don't take is a stim you keep.
• Bring a stim source for the team. Players are already suggesting that "a few stim guns in the squad could do wonders." A teammate with a stim-firing sidearm can stim you without spending your own supply.
• Watch your squadmates. Arrowhead's own advice: "a poisoned squadmate may need that stim to keep going." Whoever is holding back the Scavengers usually needs it first.

How do you deal with webs?

Webs are the other half of the mobility attack. You'll run into them three ways: a Web Spit hit, a Web Explosion, and the webs "now draped across the battlefield" on Noxious maps. In every case the effect is the same: you lose your sprint.

How to play around them:

• Break line of sight on a Spewer you can't kill yet. Web Spit is a medium-range attack. Behind a rock, it can't land it.
• Don't group up around a Spewer kill. That's how one abdomen burst snares the whole squad. Spread out before you pop it.
• Clear the Scavengers first, then fight Spewers. A webbed Helldiver with Scavengers already on them is in trouble. A webbed Helldiver with nothing nearby is just slow for a moment.
• Lean on stratagems over movement. If you can't run, make sure you don't have to. Sentries and turrets that cover your position do the running for you.

What changed with bug caves?

The second half of the November 3 drop matters just as much. Per the Ministry of Truth, "bug caves are no longer limited to a handful of worlds; they now have a chance to appear across more biomes on the Galactic map." In their words: "Every planet may have a hive beneath it."

Caves and the Noxious Strain are designed as a pair. Arrowhead describes the tunnels plainly: "sightlines are short, corners are blind, and fast enemies arrive before you hear them. Absolutely ideal territory for those Noxious bugs." Its loadout advice for the caves: "Bring close-range firepower, stay with your squad, and keep a stim in reserve for whoever wandered too far ahead."

What that means in practice:

• Long-range builds lose value underground. A sniper that's great on an open plateau fights at a disadvantage around a blind corner.
• Don't count on your Eagle underground. Players are already joking about the relief of "when you finally exit a cave, and can use Eagle 1." Plan to fight a cave mostly with what you carry in, and treat your Eagle and orbital calls as surface tools.
• Stick together. A diver who wanders off in a cave gets poisoned, webbed and isolated, and nobody can reach them with a stim.

What is the best loadout for the Noxious Strain?

Helldivers 2 has no single "best" loadout. The right kit depends on difficulty and on whether your mission sends you underground. This is a starting point for difficulties 7 to 10 (Suicide Mission through Super Helldive) on a Noxious planet with caves, built directly on Arrowhead's own advice:

Slot	Recommendation	Why
Primary	SG-225 Breaker or SG-451 Cookout (or R-40 Sightliner if you can land headshots)	Volume of fire for fast, fragile Scavengers; the Sightliner is the precision option players are reporting
Secondary	A stim-delivery sidearm, or a fast-firing pistol	Stim a poisoned teammate without burning your own stims
Grenade	Impact or incendiary grenades	Break Scavenger packs before they reach you
Support weapon	FLAM-40 Flamethrower for caves; a medium-pen support for open maps	Flame dominates tunnels; you still need an answer for Chargers and Bile Titans on the surface
Armor passive	Anything that adds stims or stim efficiency	Your stims now do double duty against poison
Stratagems	One sentry, one anti-heavy option, one cave-safe tool	Webs stop you running, so let turrets hold the line

For your anti-heavy slot, the regular Terminid threats haven't gone anywhere. Our best Terminid loadout guide and the best support weapons ranking cover Chargers, Impalers and Bile Titans. The Noxious units don't replace those, they come on top of them.

Is the Noxious Strain hard?

Players are split. Some early reactions call it a stim tax, while others argue the strain is a welcome change to bug fights that had become routine. The honest answer: it isn't harder if you change your habits, and it's much harder if you don't. Squads that sprint away from every fight, spread out in caves, and spend stims at full health will struggle. Squads that clear Scavengers first, pop Spewers at range and ration stims will find it manageable on every difficulty up to Super Helldive.

The community is already asking for more. One popular thread asks which other spiders the strain should borrow from next, with suggestions like brood mothers and wall-crawlers. Nothing beyond the two units has been announced, so treat any "new Noxious unit" claim you see before an official post as speculation.

FAQ

When did the Noxious Strain come out in Helldivers 2? It went live on November 3, 2026, announced the same day on Steam and the PlayStation Blog. It didn't come with a numbered patch. The current build is still Devoid of Liberty 7.2.2 from October 29, 2026.

How many Noxious enemies are there? Two have been announced: the Noxious Scavenger and the Noxious Spewer. Arrowhead hasn't confirmed any other Noxious units, so ignore lists claiming more.

How do you cure poison in Helldivers 2? Use a stim. Arrowhead says stims "help cure" poison. They knock the build-up back rather than resetting it instantly, so stim as poison builds instead of waiting until you're Heavily poisoned and can't sprint. A teammate's stim sidearm saves your own supply.

Where is the Noxious Spewer's weak spot? Its abdomen. The head has medium armor, but the web-filled abdomen has no armor at all. Hit it from range, because bursting it triggers a Web Explosion that snares every Helldiver and bug nearby.

Why can't I sprint in Helldivers 2? On Noxious planets it's almost always a web or heavy poison. A Noxious Spewer's Web Spit, its Web Explosion, and the Heavily poisoned state all take away your sprint. Stim early so poison never reaches the heavy tier, and break line of sight on any Spewer you can't kill yet.

Are bug caves on every planet now? Not guaranteed. Caves now have a chance to appear across more biomes, not just the handful of worlds they used to be limited to. Expect them on Terminid planets of almost any climate.
