Helldivers 2's bug front just got nastier. Arrowhead Game Studios has pushed a new Terminid variant into the galaxy, the Noxious strain, and it arrives alongside a quieter but arguably bigger change: Terminid cave networks are no longer confined to a handful of planets and can now turn up beneath far more of the biomes on the Galactic map. Both changes went live on November 3, and they come with something the game has not had in this form before: a dedicated poison status with its own HUD icon and two escalating stages.
What the Noxious strain actually is
The Noxious strain is not an entirely new family of bugs. It is a venomous take on two familiar Terminid types, Scavengers and Spewers, rebuilt around speed and poison. In practice that matters because Helldivers already have muscle memory for both, and the new versions are designed to punish exactly that familiarity. A Scavenger you would normally ignore until it is at your ankles, or a Spewer you would expect to drag itself slowly towards you, now closes the gap far faster than the old habits allow for.
The common thread is venom. Every bite from a Noxious bug applies poison, and Arrowhead has framed the whole strain around what that poison does to a squad over the course of a fight rather than in a single hit.
Noxious Scavenger: small, fast and quick to bite again
The Noxious Scavenger looks almost identical to the standard version at a glance, which is the point. It is noticeably faster than its cousin, harder to keep in your sights, and each bite carries a dose of poison. It also recovers quickly enough to bite again almost immediately, so a single one that slips through a firing line can do far more damage than its size suggests.
The trade-off is that it is fragile. Arrowhead's own advice is to favour weapons that reward volume over precision, such as shotguns, flamethrowers and grenades. Swarms of fast, weak enemies have always been where spread and area damage shine, and the Noxious Scavenger leans hard into that.

Noxious Spewer: the big one, and the source of the webs
The headline addition is the Noxious Spewer, a hulking bug that throws out the old idea of Spewers as slow, lumbering artillery. It moves with real speed, and it is responsible for the webbing that now coats parts of the battlefield.
Its kit has three parts worth knowing. At medium range it uses a Web Spit; one hit removes your ability to sprint, which is precisely how it sets up its next move. Up close it has a quick bite with surprising reach that carries a heavier dose of venom than anything a Scavenger can inflict. And its abdomen, swollen with web, is completely unarmoured, while its head sits behind medium armour.
That soft abdomen is the obvious weak point, but it comes with a catch. When the sac bursts it triggers a Web Explosion that snares every Helldiver and every bug caught nearby. Shooting it from a distance is the clean answer. Shooting it while a teammate is standing next to it is a good way to pin your own squad in place in the middle of a swarm.

How poison works now
Poison gets its own icon on the HUD so you can see how badly you have been hit, and it runs in two stages:
- Lightly poisoned: your vision begins to haze and the poison starts eating away at your health.
- Heavily poisoned: the damage over time increases, you lose the ability to sprint, and your vision hazes further.
Stims cure the condition, which turns them into a resource you will have to think about more carefully than before. A poisoned squadmate may need that stim more than you need the top-up, and a team that burns through its supply early in a bug mission is going to feel it later. Losing sprint at the heavy stage stacks badly with the Spewer's Web Spit, too: between the two, getting caught out in the open becomes much more dangerous than it was a week ago.
Bug caves can now appear on far more planets
The second half of the update is arguably the bigger change to how missions play. Terminid cave networks, which were previously limited to a handful of worlds, now have a chance to appear across more biomes on the Galactic map, from desert worlds to frozen tundra. In other words, almost any Terminid planet may now have a hive beneath it.
Caves change the rhythm of a mission. Sightlines are short, corners are blind, and fast enemies can be on you before you hear them coming, which makes them ideal territory for a strain built around speed and venom. Arrowhead's recommendation is close-range firepower, a squad that stays together, and a stim kept back for whoever wanders too far ahead.

Why it matters
Helldivers 2 has spent much of this year adding variety through Warbonds, crossovers and enemy reworks. This update instead changes the threat itself. A status effect that removes sprint and drains health over time, and a cave layout that can now appear on far more worlds, both push squads towards tighter play and more deliberate loadouts on the Terminid front. If you have been running long-range builds against the bugs, now is a good time to pack a shotgun, a flamethrower or a few extra grenades before you drop.
