The ARC-3 Arc Thrower has quickly become one of the standout tools in Helldivers 2, offering a unique chain lightning effect that can wipe out groups of enemies if used correctly. For players new to the weapon—or those looking to refine their technique—understanding the fundamentals of its mechanics is essential.
Understanding Chain Lightning
The ARC-3 doesn’t operate like your standard projectile weapon. Instead, it emits electrical arcs that jump between enemies, making positioning and target priority crucial. The lightning chains most effectively when enemies are clustered together, so keeping an eye out for dense enemy packs is key. Unlike single-target weapons, the ARC-3 rewards careful planning over rapid firing.
Optimal Usage
Engage Early, Then Retreat
Start by targeting the front line of enemy waves. The chain effect will naturally seek nearby targets, allowing you to thin out clusters without exposing yourself too much. After the initial strike, repositioning is critical to avoid being overwhelmed.
Environmental Awareness
The ARC-3 interacts with the environment in subtle ways. Metallic surfaces can sometimes amplify the chain effect, but walls and obstacles may block arcs from reaching their next target. Knowing the terrain can make the difference between a devastating chain and wasted energy.
Energy Management
Unlike conventional weapons, the ARC-3’s ammo pool is limited and recharges slowly. Timing your shots for maximum impact is far more important than continuous firing. Conserving energy for moments where multiple enemies are lined up will yield the highest efficiency.
Gear Synergy and Considerations
Pairing the ARC-3 with crowd control grenades or abilities can create devastating combos. For example, temporarily slowing enemy movement before unleashing the chain lightning ensures more hits and faster wave clear. In cooperative play, coordinating with teammates to funnel enemies into tighter formations will amplify the weapon’s effectiveness.
