Helldivers 2: Best Support Weapons

Weaponry in Helldivers 2 isn’t just limited to rifles and pistols. Support weapons are designed to fill-in for specific combat roles, giving players the edge they need to beat back huge swarms or bust heavy armor open.

Some of these support weapons do have overlapping roles, and one option might be better than the other at doing its specified job. Here’s a list of the best support weapons in Helldivers 2 to give you an idea of what you should unlock first.

5 M-105 Stalwart

High Mobility Bullet Hose

• Role: Anti-Infantry
• Call-in Time: 3 Seconds
• Cooldown Time: 480 Seconds

The Stalwart is essentially a high-capacity assault rifle. It isn’t as cumbersome to handle as the heavier MG-43 Machine Gun, but it doesn’t deal as much damage as its larger counterpart either. Still, this gun serves as an excellent support weapon for laying down suppressive fire on bots or cutting down swarms of bugs while on the move.

One of the best things about the Stalwart is its ability to reach a blistering rate of fire. Hold down the Reload button to open the Fire Mode selector, set the weapon to 1150 RPM, and watch as it shreds lightly armored targets to ribbons.

4 AC-8 Autocannon

Outflank and Destroy

• Role: Heavy Infantry Destroyer
• Call-in Time: 3 Seconds
• Cooldown Time: 480 Seconds

The Autocannon is great for taking out medium-sized enemies like Devastators, Scout Striders, and Spewers. It’s also useful in a pinch against heavily-armored targets like Chargers, Bile Titans, and Hulks as long as the gunner can aim for vulnerable spots, which are usually on the flanks, backs, or faces of enemies.

Autocannons don’t need to be reloaded with every shot, and when it does need a new clip, a manual reload from the gunners themselves doesn’t take too long, keeping it reliable even if team reloads aren’t available. However, if you’re looking for a precision anti-armor weapon that’s even lighter, then the Anti-Materiel Rifle is a good alternative.

3 GL-21 Grenade Launcher

Anti-Infantry Pocket Artillery

• Role: Anti-Infantry/Spawner Destroyer
• Call-in Time: 3 Seconds
• Cooldown Time: 480 Seconds

While it isn’t intended for taking down armor, the Grenade Launcher is amazing at clearing clustered groups of enemies. It’s also very effective at blowing bug holes and bot fabricators, destroying Spore Spewers, and taking out Automaton machine gun nests.

If you bring a Supply Pack, you’ll essentially get unlimited grenades for as long as the pack contains ammunition. Bring a Grenade Launcher if no one else takes an anti-infantry weapon with them.

2 GR-8 Recoilless Rifle/Expendable Anti-Tank Launcher

SEAF Standard Tank Busters

• Role: Anti-Tank
• Call-in Time: 3 Seconds
• Cooldown Time 480 Seconds (GR-8)/70 Seconds (EAT)

These two rocket launchers are the staple anti-tank weapons in Helldivers 2. The Recoilless Rifle can blow up priority targets very quickly if the gunner has a teammate to assist with reloads. Both are great for anything that’s heavily armored, and every team should bring at least one of these if they’re going on hard missions.

The main thing to consider when picking between these is team coordination. If you’re playing a casual public game with strangers, it’s better to bring the EAT so you don’t have to worry about team reloads. Otherwise, ask your squadmates if they can carry a Recoilless Rifle backpack for you.

1 RS-422 Railgun

The Most Versatile Armor Hunter

• Role: Anti-Armor
• Call-in Time: 3 Seconds
• Cooldown Time: 480 Seconds

As of launch, the Railgun is arguably the best support weapon in Helldivers 2. It can strip heavy armor and knock medium enemies out in one shot, especially if that shot is overcharged. The Railgun is much better than the Autocannon and AMR for fighting armor, but its DPS is poor, making it less valuable when the immediate extermination of a target is required.

Railgun shots can punch through even Bile Titan armor. However, using it against targets with high health should only be a last resort. Rely on dedicated anti-tank weapons or stratagems to deal with large targets as quickly as possible.
