G-31 Arc Guide: Stats, Tips, and How to Use It in Helldivers 2

The G-31 Arc is one of those throwables that looks simple on paper but feels completely different once you actually use it in a mission. It's not your standard “pull pin, boom” grenade. Instead, it acts more like a portable lightning storm that you throw on the ground and immediately regret standing near. If you're trying to figure out whether it's worth unlocking or how to use it safely, this guide breaks down everything you need to know — in simple, easy-to-read terms.

What Exactly Is the G-31 Arc?

The G-31 Arc is a Special Throwable found in the Control Group Premium Warbond (Page 3) and costs 65 Medals to unlock.

Instead of exploding once, it fires five bursts of electrical arcs in a wide area. After you throw it, it becomes static on the ground and starts zapping everything around it. Think of it as a mini De-Escalator — except it bounces a bit and acts like it's had too much coffee.

If you ever find yourself just a few Medals short, some players simply buy helldivers 2 medals online from U4GM to unlock tools like the G-31 Arc a little sooner without slowing down their grind.

How the Arc Effect Works

Each arc deals 100 Arc damage (70 vs. Durable targets), has Heavy penetration, and can reach up to 10 meters.

Key points:

• It fires five arc bursts in total.
• Each burst can hit multiple targets or, sometimes, the same target several times if nothing else is nearby.
• It can stun small enemies, giving you room to reposition.
• It bounces slightly between bursts, which can make its path unpredictable.

And yes — it can kill you. Very fast. Even in heavy armor. If you're the only “valid target” nearby, the grenade will absolutely choose you.

How Effective Is It Compared to Other Throwables?

Great For:

• Crowds and swarm control
• Bug Rushes, tight corridors, defensive holds
• Stunning lighter enemies so your team can clean up
• Creating danger zones that slow pushes from hordes

Not Great For:

• Destroying structures (bug holes, fabricators, etc.)
• Heavy armored enemies (the damage helps but won't delete them)
• Precision use — it's chaotic by nature
• Tight spaces when teammates are nearby (unless you dislike your squad)

If you want pure destruction, you'll need something like the Grenade Launcher, Exploding Crossbow, or Grenade Pistol.

Drawbacks and Limitations

Some things to watch out for:

• Unpredictable bounce behavior — terrain makes it wiggle in weird ways.
• Friendly fire magnet — arc weapons don't care who they hit.
• Cannot destroy bug holes or fabricators due to low demolition force.
• Activates only after you throw or drop it — no cooking.
• Hard to use in tight tunnels because you might zap yourself by accident.

If you're playing with random teammates, maybe warn them before tossing one. Or don't — but expect screams.

Best Ways to Use the G-31 Arc

A few simple play tips:

1. Use It for Area Denial

Drop it in front of a swarm and let the arcs do the job while you keep shooting or repositioning.

2. Combine With Stagger Weapons

Weapons like shotguns, arc rifles, or crowd-control stratagems pair well with it.

3. Avoid Throwing It Uphill or on Slopes

Its bounce becomes even more random on uneven ground.

4. Use It While Kiting

Throw it behind you as you retreat — the chasing enemies run straight into the zap zone.

5. Keep Distance

Arc damage chains. Distance is safety. Armor doesn't guarantee survival.

Is It Good in High-Difficulty Missions?

Surprisingly, yes — but only in the right hands.

The G-31 Arc scales well for:

• Clearing huge waves
• Stunning mobs long enough to escape
• Supporting teams holding a point or uploading data

However, it's not a replacement for structure-destroying tools, and careless use can ruin a mission fast. On higher difficulties, its friendly-fire risk becomes the main thing you need to master.

How to Unlock the G-31 Arc

• Find it in the Control Group Premium Warbond
• Located on Page 3
• Costs 65 Medals

Once unlocked, you get 2 starting grenades and 4 spares, which is enough to get a lot of value during missions.

Do Players Actually Use It?

Yes — but usually players who enjoy utility tools, area control, or chaotic weapons.

Most players see it as:

• Fun: The arcs look cool and feel satisfying against hordes.
• Situational: Not good for every biome or mission type.
• Deadly: Both to enemies and careless teammates.
• Useful: When you know what you're doing.

It isn't meta, but it has a strong niche and rewards smart positioning.

Summary

The G-31 Arc is a unique throwable that acts like a roaming lightning trap. It shines at clearing hordes, stunning light enemies, and controlling enemy paths. Its weaknesses — friendly fire, unpredictability, and poor structure-breaking power — mean it requires careful play. If you enjoy chaotic tools that reward smart placement, it's absolutely worth unlocking and mastering.
