The Autocannon is one of the most reliable and versatile support weapons in Helldivers 2. It delivers powerful explosive rounds, capable of tearing through hordes of Terminids or knocking down tough Automatons with ease. But to make the most out of this weapon, you need the right loadout, Stratagems, and team setup. In this guide, we’ll go over five of the strongest Autocannon builds that will help you dominate the battlefield and support your squad effectively.
1. Heavy Infantry Support Build
If your squad relies on you for suppressive fire, this setup ensures you can hold the line.
- Primary Weapon: AR-23 Liberator
- Support Weapon: Autocannon
- Grenade: Impact Grenade
- Stratagems: Supply Pack, Shield Generator Pack, Eagle Cluster Bomb, Reinforce
Playstyle:
Use the Shield Generator Pack to tank damage while laying down consistent Autocannon fire. This build works great in choke points and defensive missions. Your Supply Pack ensures you never run dry on ammo, allowing continuous suppression against incoming swarms.
2. Anti-Armor Specialist Build
Perfect for missions filled with tanks, Devastators, or Chargers.
- Primary Weapon: Eruptor
- Support Weapon: Autocannon
- Grenade: Thermite
- Stratagems: Orbital Railcannon Strike, Recoilless Rifle, Ammo Drop, Guard Dog
Playstyle:
The Autocannon’s high-velocity rounds can take out medium armor, while your Orbital Railcannon deals with the big threats. Pairing with another heavy user gives you strong burst potential. Always aim for weak spots and let your Guard Dog cover smaller enemies while you reload.
3. Mobile Fire Support Build
This one’s for players who like to stay on the move while dealing massive damage.
- Primary Weapon: SMG-37 Defender
- Support Weapon: Autocannon
- Grenade: Stun Grenade
- Stratagems: Jump Pack, Eagle Strafing Run, Supply Pack, Resupply

Mobility is the key here. Use your Jump Pack to reposition and find safe firing angles. The Stun Grenade helps you control crowds when you need a moment to reload. This setup excels in missions where mobility and flexibility are essential to survival.
4. Defensive Turret Commander Build
If you love turning missions into a fortress of steel and explosions, this is your go-to.
- Primary Weapon: SG-225 Breaker
- Support Weapon: Autocannon
- Grenade: Incendiary
- Stratagems: Machine Gun Turret, Mortar Sentry, Shield Generator Relay, Resupply
Playstyle:
Set up a perimeter with sentries and hold your ground. The Autocannon provides additional firepower, shredding enemies that breach your turret defenses. The Shield Relay keeps your team protected while your turrets and Autocannon handle most of the work.
5. Solo Survival Build
For those who prefer solo drops or need to clutch a mission when things go wrong.
- Primary Weapon: LAS-5 Scythe
- Support Weapon: Autocannon
- Grenade: Smoke Grenade
- Stratagems: Orbital Precision Strike, Supply Pack, Resupply, Reinforce
Playstyle:
The Autocannon’s damage output gives you a strong edge against waves of enemies. Use smoke to escape or reload safely. The Scythe’s infinite ammo ensures you always have a backup weapon ready, while Orbital Precision Strike handles distant targets.
Final Tips for Mastering the Autocannon
The Autocannon’s biggest weakness is its reload time. Always communicate with your team so someone can cover you during reloads. Remember that its explosive splash can damage teammates—maintain good positioning and fire discipline.
