Helldivers 2 Update Adds Poisonous Noxious Bugs and Underground Cave Networks

Arrowhead Game Studios community manager Mitchell Ayre detailed a major Helldivers 2 update on November 3, 2026, confirming the arrival of a new venomous Terminid strain alongside subterranean cave networks expanding across all galactic biomes. Designated as the Noxious strain, these web-weaving bugs add lethal poison status effects and tight underground combat to the Galactic War.

According to the official Ministry of Truth briefing, the update brings two primary new enemy variants—the skittering Noxious Scavenger and the heavy-armored Noxious Spewer—while forcing squads into low-visibility tunnel operations on planets ranging from frozen tundras to scorched deserts.

The details

• New enemy variants: Noxious Scavenger (small, fast, venomous) and Noxious Spewer (hulking, web-spitting, unarmored abdomen).
• Poison status mechanics: Bites inflict Light (hazed vision, health decay) or Heavy (increased damage over time, sprint disabled) poison status tracked on the HUD; cured using stims.
• Expanded cave biomes: Bug caves now appear across all planet biomes on the Galactic map, featuring short sightlines and blind corners.
• Web hazards: Noxious Spewers use Web Spit to disable sprinting and explode into snaring webs upon death if their unarmored abdomen bursts.

How does the Noxious strain attack

The Noxious Scavenger moves significantly faster than standard Scavengers, delivering immediate doses of venom with rapid, repeated bites. Arrowhead noted that high-volume area weapons—including shotguns, flamethrowers, and grenades—are the most efficient counter to their low health pools, reminding players that ammunition remains cheaper than antivenom.

The larger Noxious Spewer introduces crowd-control hazards to medium-range engagements. Beyond its rapid venomous bite, the creature fires Web Spit that removes a player's ability to sprint. While its head is protected by medium armor, its web-filled abdomen remains unarmored. Destroying the abdomen triggers a Web Explosion, snaring all nearby Helldivers and bugs in silk.

Poison damage is monitored through a dedicated HUD icon across two distinct severity levels:

• Lightly poisoned: Hazed vision accompanied by gradual health decay.
• Heavily poisoned: Increased damage over time, hazed vision, and the complete loss of sprint capability.

Stims cure both forms of poisoning, making tactical resource sharing essential for survival.

Where are bug caves appearing

Subterranean Terminid cave networks are no longer restricted to select environments. Under the new update, bug hives have a chance to generate across any biome on the Galactic map, bringing close-quarters underground warfare to environments from desert sands to icy tundra.

Inside the tunnels, short sightlines and blind corners amplify the speed of Noxious bugs, requiring squads to rely on close-range firepower, tight formations, and reserved stim supplies to survive ambushes.

Why it matters

The addition of the Noxious strain and map-wide subterranean cave generation systematically alters combat pacing across the Terminid front. By introducing mandatory sprint-disabling webs and HUD-tracked venom damage that requires tactical stim management, Arrowhead Game Studios has expanded environmental hazard complexity within procedural missions across the Galactic map.
