G-142 Pyrotech – Helldivers 2 Full Guide

If you enjoy throwable weapons that feel chaotic, flashy, and genuinely useful across multiple situations, the G-142 Pyrotech is one of those grenades that instantly clicks. It's technically a Special Throwable, but in practice it behaves like a mini area-denial tool, an anti-armor splash weapon, and a “set-everything-on-fire-at-once” button. After a few sessions with it, you start to understand why players call it one of the most versatile throwables in the game.

Below is a full breakdown of how it works, its strengths and weaknesses, and how to build around it.

Main Parameters

Basic Profile 
• Damage: 20 Fire DPS + 50 Explosion

Lingering Fire DPS Mode

Strengths

Wide Area Coverage 
The Pyrotech sprays sparks before exploding, which means you're already softening crowds and lighting up the battlefield even before the main blast goes off. It controls space extremely well.

Surprisingly Strong Anti-Armor 
Even though the base stat says “Medium Penetration,” the fire damage itself actually penetrates Heavy armor tier. That's why the Pyrotech can:

• Kill Hulks reliably 
• Melt Factory Striders with 2 well-placed throws 
• Chip Chargers (less consistent, but doable) 
• Burn through armored patrols without aiming a weak point

This alone makes Pyrotech more flexible than most grenades in Helldivers 2.

Crowd Control + Area Denial 
Between the sparks, the explosion, and the lingering fire, enemies entering your zone basically set themselves on fire. On high-density missions, this buys your squad breathing room.

Resupplies Well 
Getting 3 charges per resupply means you can keep the pressure up without constantly worrying about running dry.

Weaknesses

Friendly Fire Hazard 
Everything here spreads fire aggressively. Your team will get roasted if they walk into your line of sight. Coordination is key.

Unpredictable Sparks 
The initial spark spray has some randomness. Most of the time this is great, but occasionally it sends a flame burst into a teammate or fails to hit the target you intended.

Less Reliable on Solo vs Striders/Chargers 
Multiplayer spawns additional sparks, which boosts damage output. Solo runs feel slightly weaker against large units.

Not a Quick Precision Tool 
If you need an instant pop with no lingering effect — e.g., blowing up a single Charger at a very specific timing — Pyrotech is slower and messier than impact grenades.

Even with its fiery chaos and occasional friendly-fire drama, the Pyrotech stays one of the most satisfying throwables to master in the game. And if you ever need extra resources to speed up your loadout progression, U4GM is the best site to buy helldivers 2 medals without any hassle.

Community Reviews (Player-Style Summary)

Most Helldivers describe the Pyrotech as:

• “The best hybrid grenade in the game.” 
• “Ridiculous at clearing chaff while melting big stuff.” 
• “A bit too spicy for teammates, but worth it.” 
• “Feels like cheating when you learn how far the flames reach.”

Players especially appreciate how it lets them replace dedicated anti-armor tools on certain builds, giving more freedom in stratagem loadouts.

Build Guide: How to Use the G-142 Pyrotech Effectively

Primary Weapon Synergies 
If you use the Pyrotech as your anti-armor option, lean toward primaries that handle crowds or precision roles:

• R-63 Diligence / Patriot Rifle – good for picking off survivors 
• SG-225 Breaker – clears softened mobs instantly 
• JAR-5 Dominator – pairs well for melting medium bugs 
• LAS-5 Scythe – works great since Pyrotech covers big AoEs

Stratagem Pairings 
• Eagle Cluster Bomb / Airstrike – follow up after fire softens groups 
• Orbital 120mm HE – Pyrotech gathers enemies tightly; HE finishes them 
• Recoilless Rifle or Spear – for consistent anti-armor if you don't trust fire RNG 
• Shield Generator Pack – helps reduce accidental self-immolation

When to Throw 
• Throw ahead of approaching swarms to create a burning corridor. 
• For large armor units, aim near the feet, not the torso — fire climbs upward. 
• For Striders, drop 2 grenades between the legs and let the flames do the work. 
• During objective defense, treat Pyrotech as a paint roller: coat the ground in fire.

Small Tips 
• If a group is chasing you, throw backwards — they run into the flames. 
• Don't spam in close quarters unless you enjoy dramatic self-rescues. 
• The explosion's shockwave is strong; you can knock smaller enemies away even if they don't light up.

The G-142 Pyrotech stands out because it's not just a grenade — it's a multi-phase lockdown tool that deals damage, controls space, melts armor, and reshapes the battlefield. Its randomness makes it feel wild, but once you get used to the spark patterns, it becomes one of the most reliable “all-rounder” throwables in Helldivers 2. If you like big effects and high utility with just a pinch of chaos, Pyrotech earns its Warbond medal cost easily.
