The Railgun has quickly become one of the most iconic and versatile weapons in Helldivers 2. While it shines in general combat, its true power is revealed during boss encounters, where precision and massive damage output can make all the difference. In this guide, we’ll break down the best Railgun loadouts for boss fights, along with tips to maximize your efficiency against these tough enemies.
Why the Railgun Works So Well in Boss Fights
The Railgun’s ability to deal consistent, armor-piercing damage makes it ideal for bosses like Chargers, Bile Titans, and other heavily armored threats. When fully charged, a well-placed shot can stagger even the most intimidating enemy, giving your squad breathing room to reposition or unload with other weapons. Unlike explosives, the Railgun is more reliable for precision targeting, especially when you need to hit weak spots.
Best Railgun Loadouts for Boss Encounters
1. The Heavy DPS Loadout

• Primary Weapon: Railgun
• Secondary Weapon: SMG or Shotgun (for crowd control)
• Stratagems: Anti-Tank Mines, Orbital Railcannon Strike, Supply Pack
• Armor Choice: Heavy armor for survivability

This setup is designed to maximize damage output against bosses. The Railgun is your main tool, while mines and orbital strikes serve as backup when the pressure becomes overwhelming.
2. The Balanced Support Loadout

• Primary Weapon: Railgun
• Secondary Weapon: Laser Pistol (no ammo worries)
• Stratagems: Shield Generator, Supply Pack, Eagle Cluster Bomb
• Armor Choice: Balanced armor for mobility and defense

This build is perfect for players who want to contribute to boss takedowns while still supporting the squad. The Shield Generator helps absorb incoming hits, and the Laser Pistol ensures you’re never caught without ammo.
3. The Mobility Boss-Hunter Loadout

• Primary Weapon: Railgun
• Secondary Weapon: SMG for fast handling
• Stratagems: Jump Pack, Eagle Airstrike, Resupply
• Armor Choice: Light armor for maximum mobility

Some boss fights demand constant repositioning. With the Jump Pack and light armor, you can move quickly to avoid devastating attacks while keeping the Railgun charged and ready for weak-point shots.
Extra Tips for Using the Railgun in Boss Fights

1. Aim for Weak Spots: Headshots and exposed areas deal the most damage. Take your time lining up the shot.
2. Charge Wisely: Overcharging risks self-damage, so always find cover when preparing your next shot.
3. Coordinate with Squadmates: Pair your Railgun fire with stun or slow effects from teammates for easier boss takedowns.
4. Manage Resources: Boss fights often run long, so resupply frequently and communicate with your squad to avoid ammo shortages.

The Railgun is one of the best tools for high-stakes encounters in Helldivers 2. By pairing it with the right loadout and strategy, you’ll find that even the toughest bosses can be brought down efficiently. Whether you’re optimizing gear, experimenting with builds, or just farming resources, remember that a well-prepared Railgun user can turn the tide of a battle.
