ARC-3 Arc Thrower Best Methods in Helldivers 2
 

The ARC-3 Arc Thrower in Helldivers 2 is one of the most powerful yet tricky support weapons to master. Unlike traditional firearms, it fires a chain of electricity that can arc between multiple targets, dealing devastating damage when used correctly. However, its effectiveness depends heavily on positioning, timing, and awareness of your squadmates. Below are some of the best methods to get the most out of the ARC-3 Arc Thrower.

Learn Its Unique Targeting

The ARC-3 does not behave like a standard rifle or heavy weapon. It locks onto enemies within its arc range, making it perfect against clustered groups. The weapon automatically chains between targets, so staying near groups of enemies increases your efficiency. Try to funnel enemies into choke points or tight areas to maximize the chain damage.

Maintain Squad Awareness

The biggest drawback of the ARC-3 is its friendly fire potential. If a teammate steps into your arc, they can get shocked, which can disrupt their actions and even knock them down. Communication is key when running this weapon. Let your squad know when you’re using it, and position yourself slightly behind the frontline to avoid accidental zaps.

Manage Reloads and Cooldowns

The ARC-3 has a long charge time, so you need to plan each attack. Don’t spam it in open fields where enemies are scattered. Instead, hold your fire until a group closes in. Pairing the ARC-3 with stratagems that slow or funnel enemies makes it easier to land devastating chain shots.

Pairing with Other Gear

Consider combining the ARC-3 with gear that helps manage crowd control. Turrets and airstrikes can keep enemies grouped together, giving you more targets for your electric arcs. This synergy makes it one of the most satisfying weapons to use in tough missions.

Building Around the ARC-3

When you plan your loadout, think about how the ARC-3 fits your overall strategy. It works best in defensive holds, escort missions, or objective defense scenarios where enemies are forced into tight areas. While it may not always be the most versatile weapon, in the right situation it can wipe out hordes in seconds.

Many players experiment with different gear setups while working toward upgrades and stronger equipment. If you’re looking to expand your arsenal, some choose to buy helldivers 2 items to save time. Others prefer to grind missions and even buy helldivers 2 super credits to unlock specific gear more quickly. However you approach progression, having the ARC-3 in your loadout adds a unique tool for taking on massive waves.


The ARC-3 Arc Thrower is not for everyone, but for players willing to master its quirks, it becomes a game-changing weapon. With smart positioning, teamwork, and careful timing, you can turn the battlefield into an electrified nightmare for your enemies. If you enjoy high-risk, high-reward weapons, the ARC-3 is well worth adding to your rotation.
