The Arc Thrower in Helldivers 2 is one of those weapons that feels completely unique. It chains lightning between enemies, shreds through armored targets, and can turn a messy fight into a clean sweep if you know how to handle it. But like any stratagem, the Arc Thrower really shines once you start upgrading it. Below, we’ll go through six must-have upgrades that will make your loadouts stronger and your co-op missions smoother.

1. Increased Chain Range

The Arc Thrower is all about hitting multiple targets at once. By boosting the chain range, you can zap groups that aren’t tightly clustered. This makes it especially effective against bug swarms and patrol groups, ensuring you don’t waste shots.

2. Faster Charge Time

One of the Arc Thrower’s weaknesses is its initial wind-up. With a faster charge upgrade, you’ll be able to fire quicker in the middle of chaotic battles. This is especially useful when enemies rush objectives, and you don’t have time to line up a long charge.

3. Improved Damage Output

It sounds obvious, but the damage upgrade is what makes the Arc Thrower terrifying. When paired with its natural chaining ability, this means you can wipe out both light enemies and medium armor threats in fewer hits, conserving energy for prolonged fights.

4. Expanded Ammo Capacity

Running out of power during an intense firefight can leave you relying on weaker weapons. With expanded capacity, the Arc Thrower can stay active for longer, making it one of the best sustained-damage options when combined with team suppression fire.

5. Overload Burst Mode

This upgrade adds a tactical layer. Overload fires a devastating burst at the cost of more energy, giving you an emergency option for when heavy enemies close in. It’s a risky but rewarding tool that experienced Helldivers can use to flip a fight instantly.

6. Stabilized Aim

Arc Throwers can be tricky to handle, especially when you’re moving under fire. Stabilized aim helps keep your shots steady and ensures your lightning arcs hit priority targets instead of scattering unpredictably.

The Arc Thrower rewards precision and patience. With these upgrades, you’ll turn it from a situational weapon into a squad-carrying powerhouse. Whether you’re farming medals, experimenting with Warbond gear, or just having fun with electrified chaos, these upgrades will keep you ahead of the curve.
