Terminids don’t hit hard one by one — they overwhelm you with numbers. Where Automatons demand long-range precision, bugs require mobility, crowd control and two or three anti-tank tools for the big units. Here’s the build that holds up on Helldive.
The anti-bug build logic
Against bugs, standing still gets you killed. The build rests on three pillars:
- Clear waves continuously (fire + explosives) without reloading every 3 seconds
- Handle Chargers and Bile Titans with dedicated anti-tank
- Stay mobile so you’re never surrounded
Primary weapon: fire dominates
An incendiary weapon is the best pick:
- SG-451 Cookout: huge stagger + fire damage over time. Great against Stalkers and Brood Commanders.
- Breaker Incendiary: melts clusters of small bugs almost on its own thanks to the DoT.
- Arc Blitzer: infinite ammo and area stun if you’d rather never manage reloads.
Fire deals continuous damage: tag a group and it burns down while you aim elsewhere.
Secondary and grenades
- Secondary: GP-31 Grenade Pistol — essential for closing bug holes from a distance without spending a stratagem.
- Backup pistol: P-19 Redeemer to escape a melee jam.
- Grenades: Impact or Incendiary Impact for breaches and Brood Commanders.
Support weapon: mandatory anti-tank
This is what separates a clean run from a wipe:
- Recoilless Rifle: one-shots Chargers (head/rear), 2 head shots on a Bile Titan. Reload is shareable with the team.
- Quasar Cannon: no backpack, no reload — just a cooldown. Perfect for solo.
- EAT-17: disposable, short cooldown, spam it on big units.
Stratagems: the breach-clearing combo
Slot 1 — Recoilless Rifle / Quasar
Your anti-tank. The rest of the build revolves around it.
Slot 2 — Eagle Airstrike
Versatile: closes bug holes, shreds medium clusters, short cooldown. The anti-bug Swiss army knife.
Slot 3 — Orbital Gas Strike (or Eagle Napalm)
Dropped directly on a breach, it continuously kills everything crawling out. One of the best kills-per-stratagem ratios in the game against bugs.
Slot 4 — Guard Dog Rover
Automatic small-bug management: it mows down trash mobs while you focus on the big units. Stops you getting nibbled from behind.
How to kill the big units
Charger
- Put a rock or obstacle between you: it charges, collides, stuns itself.
- Hit the exposed rear (the soft part) with your primary.
- Or one-shot the head with Recoilless/Quasar/EAT.
- In a hurry? Stun grenade + anti-tank shot = guaranteed kill.
Bile Titan
- Head with Recoilless/Quasar: 2 well-placed shots is enough.
- Or wait for its spit animation and drop an Eagle 500kg between its legs: it stops moving, the blast finishes it.
- Never waste your primary on it — it’s a waste of time.
How to play the build
Solo
- Stay always moving, run circles, never let yourself get cornered.
- Let the Rover handle the small stuff; focus on Chargers/Titans.
- Keep an EAT/Quasar ready for every big unit that spawns.
- Close breaches with the Gas Strike the moment they open.
Team of 4
- 1-2 players on anti-tank (Recoilless + backpack carrier), 2 players on crowd control (fire + Rover).
- Stack Eagle/Orbital on the same breaches to choke them shut.
- Always keep one stratagem in reserve for extraction.
Common mistakes to avoid
- Standing still → surrounded and drowned in 5 seconds.
- Shooting your primary at a Bile Titan → useless, save the anti-tank.
- Ignoring breaches → they spit endless reinforcements, close them fast.
- Heavy armor → you lose mobility, which is your only defense against bugs.
Patch update
Confirmed working on the current patch (incendiary weapons and anti-tank have dominated the Terminid meta since the early-2026 patches). We update this article with every major balance change.
Conclusion
The anti-bug build rewards movement discipline: as long as you kite and deal with the big units using anti-tank, the waves melt on their own under fire and orbitals. It’s twitchier than the anti-bot setup, but once you find the rhythm, Helldive against Terminids becomes a playground.
Frequently asked questions
Which primary weapon against Terminids?
An incendiary one: the SG-451 Cookout (stagger + fire damage over time) or the Breaker Incendiary. Fire deals continuous damage that clears small-bug waves without burning through ammo.
How do you kill a Charger fast?
Keep an obstacle (a rock) between you so it rams and stuns itself, then hit the exposed rear. Or one-shot the head with a Recoilless Rifle / Quasar / EAT. A stun grenade plus an anti-tank shot is the most reliable method.
What's the best way to kill a Bile Titan?
Aim for the head with the Recoilless/Quasar (2 hits), or drop an Eagle 500kg between its legs during its spit animation: it stops moving and the blast finishes it.
Light or heavy armor against bugs?
Light, no question. Against Terminids it's all about kiting — you must stay mobile to avoid being surrounded. Heavy armor gets you swarmed and killed.
