Mastering the Autocannon and Heavy Weapons
To effectively use the Autocannon and other heavy weapons in Helldivers 2, you need to master a trifecta of roles: positioning as a mobile firebase, understanding precise ammunition mechanics, and coordinating with your team’s loadout. It’s not just about having the biggest gun; it’s about being the team’s strategic linchpin. This involves knowing when to engage, what to prioritize, and how to manage your resources to avoid becoming a liability.
The Autocannon: Your Go-To All-Rounder
Think of the Autocannon as the workhorse of the heavy weapon category. It strikes a critical balance between rate of fire, damage output, and ammunition efficiency. Unlike a single-shot recoilless rifle, the Autocannon allows for sustained suppression and can handle waves of medium armor targets with precision. Its effectiveness, however, is entirely dependent on your positioning. You are most effective when deployed on a slight elevation or with a clear line of sight, as the weapon’s accuracy suffers significantly when fired on the move. The key is to find a spot that covers a choke point or a major approach path, drop to a prone or crouched position, and unleash controlled bursts. A common mistake is treating it like an assault rifle and trying to advance while firing; this wastes ammo and gets you killed. A three-round burst is typically enough to destroy a Devastator or a Hunter, while a full five to eight rounds might be necessary for the side armor of a Hulk.
The ammunition system is what separates good Autocannon users from great ones. You carry a finite amount of shells, and resupply is a strategic decision. Each ammo pack replenishes a specific number of rounds, not a percentage of your total capacity. This makes ammunition conservation paramount. You should never “spray and pray.” Instead, focus on disciplined, aimed fire. Prioritize high-value targets that pose an immediate threat to the team’s objective or that other weapons struggle with. Let your teammates with standard rifles handle the small fry. The following table breaks down the Autocannon’s engagement profile against common armored threats on Superm Earth’s more challenging difficulties.
| Target | Armor Type | Recommended Shot Placement | Average Rounds to Destroy (Helldive Difficulty) |
|---|---|---|---|
| Hulk (Automaton) | Heavy (Front), Medium (Back) | Rear exposed core | 10-12 |
| Tank (Automaton) | Heavy (All Sides) | Does not penetrate; use for support/suppression | N/A (Ineffective) |
| Bile Titan (Terminid) | Heavy (Body), Medium (Head) | Mouth when open or legs to slow it | |
| Charger (Terminid) | Heavy (Head/Front), None (Rear Leg) | Unarmored back leg | 5-7 |
Heavy Weapon Arsenal: Choosing the Right Tool
The Autocannon is brilliant, but it’s not always the perfect choice. Your team’s success hinges on having a balanced arsenal that can address any threat. This is where understanding the other heavy weapons becomes critical. The Recoilless Rifle is your premier tank-buster. It’s a single-shot, high-velocity weapon that requires a backpack for reloads, making a two-person team incredibly efficient. One person fires, the other reloads, creating a continuous cycle of destruction. It’s the only man-portable weapon that can reliably one-shot a Automaton Tank from the front with a precise hit. However, its slow rate of fire and reliance on a buddy make it vulnerable in chaotic, close-quarters fights.
On the opposite end of the spectrum is the Flamethrower. Its effectiveness is not measured in single-target damage but in area denial and crowd control. Against the Terminid swarm, a well-placed wall of fire can stop an entire charge of Hunters and Warriors in their tracks. It ignores armor on smaller creatures and causes them to panic, buying your team precious seconds. The downside is its extremely short range and the very real risk of friendly fire. Using a flamethrower requires strict communication and spatial awareness.
Then there’s the Spear, a lock-on missile launcher. It’s the ultimate “fire-and-forget” weapon for taking out high-priority targets like Bile Titans or Factories. The lock-on mechanic requires a steady aim and a clear view of the target for a few seconds, which can be difficult under heavy fire. It also has very limited ammunition, so every shot must count. Wasting a missile on a trivial target is a major strategic blunder.
Advanced Tactics and Team Synergy
Your effectiveness with a heavy weapon is multiplied when you synergize with your team’s Stratagems and other gear. For example, an Autocannon user becomes exponentially more deadly when a teammate calls in a Tesla Tower or deploys a Machine Gun Sentry. These Stratagems can thin out the smaller enemies, allowing you to focus entirely on the armored threats that your weapon is designed for. Similarly, using an Eagle Smoke Strike can provide the cover needed for a Recoilless Rifle team to safely reposition and reload.
Communication is non-negotiable. Calling out your targets and your ammo status prevents your teammates from wasting their own resources. A simple callout like “Autocannon on the Hulk’s back, cover me” tells your team exactly what you’re doing and what you need from them. Furthermore, always be aware of your team’s overall loadout. If no one has brought a dedicated anti-tank weapon like the Recoilless Rifle or Spear, then your role with the Autocannon shifts; you become the primary handler for medium armor, and the team must rely on Stratagems like the Eagle 500kg Bomb or Orbital Railcannon Strike to deal with the heaviest targets.
Finally, manage your stamina. Heavy weapons slow you down. Constantly sprinting will drain your stamina bar, leaving you unable to dive—your primary evasion tool—when a Charger decides to charge. Pace your movements, use cover intelligently, and never be the last one in the retreat. A live heavy weapons specialist is a strategic asset; a dead one is just a marker on the map.
