The definitive best weapons in Helldivers 2 for Super Helldive and high-difficulty Operations are the JAR-5 Dominator, LAS-16 Sickle, and PLAS-1 Scorcher for Primary slots, paired with the AC-8 Autocannon, LAS-99 Quasar Cannon, and EAT-17 Expendable Anti-Tank in the Support slot. For your Secondary slot, the GP-31 Grenade Pistol stands unmatched due to its ability to instantly destroy Automaton Fabricators and Terminid Bug Holes. With balance patches continually shifting weapon damage values, armor penetration values, and stagger force, staying equipped with top-tier gear is vital for surviving Level 7 to 10 missions.
S-Tier Helldivers 2 Weapons: Absolute Meta Dominance
S-Tier weapons represent the absolute peak of damage output, armor penetration efficiency, and ammo economy. These firearms excel across both the Automaton and Terminid fronts, providing reliable crowd control and high damage per second (DPS) without leaving you vulnerable to heavy counterattacks. If you want to dive into official server missions on Helldivers 2 on Steam with peak loadout efficiency, these are the tools you must prioritize.
JAR-5 Dominator (Primary Rifle)
The JAR-5 Dominator remains a undisputed juggernaut. Firing jet-assisted explosive rounds that deal 275 base damage alongside Medium Armor Penetration (Armor Class 3), this weapon completely trivializes heavily armored infantry like Automaton Devastators, Berserkers, and Terminid Hive Guards. The staggering 30 Stagger Value per shot knocks Devastators out of their rocket-firing animations, interrupting lethal volleys. While its ergonomics are sluggish, adjusting your aiming drag makes this the premiere pick for high-difficulty Automaton operations.
LAS-16 Sickle (Primary Energy Weapon)
For clearing trash mobs across Terminid planets, the LAS-16 Sickle is second to none. Functioning on an energy heat-sink mechanism, it offers theoretically infinite ammunition as long as you swap heat sinks before overheating. Delivering a laser-like fire rate of 750 RPM with zero bullet drop, it rips through Terminid Hunters, Pouncers, and Scavengers effortlessly. Its crisp accuracy and negligible recoil make it superior to basic kinetic assault rifles for clearing light enemies fast.
PLAS-1 Scorcher (Primary Energy Weapon)
The PLAS-1 Scorcher fires plasma projectiles that detonate on impact, creating a small explosive splash that bypasses heavy frontal armor. It is the premier primary counter to Automaton Scout Striders, destroying the pilot behind the armor plate in just two body shots. Furthermore, the splash damage penetrates the rear weak spots of Chargers and Spewers without requiring precise line-of-sight. Its only downside is a modest 15-round magazine, requiring disciplined trigger control.
AC-8 Autocannon (Support Weapon)
The AC-8 Autocannon is the baseline standard against which all Arrowhead Game Studios design decisions are measured. Offering a 10-round internal magazine loaded via 5-round stripper clips, it features Medium-Plus Armor Penetration, explosive area-of-effect damage, and massive armor stripping capabilities. It destroys Automaton Fabricators, Bug Holes, Spore Spewers, and Broadcast Towers from hundreds of meters away. It can stagger Hulks with eye-shot bursts and shatter Gunship engines in two rapid shots, making it an irreplaceable cornerstone of any co-op team synergy build.
LAS-99 Quasar Cannon (Support Energy Weapon)
The LAS-99 Quasar Cannon delivers heavy anti-tank explosive firepower without requiring a backpack slot. By charging up a shot over 3 seconds, it unleashes a high-velocity particle beam that deals massive direct anti-tank damage (Armor Class 6 penetration). A single well-placed shot to the head will instantly kill a Terminid Charger or down an Automaton Drop Ship by hitting one of its four engines. Because it cools down over 15 seconds rather than utilizing reloadable ammo, you can move freely across the map while preparing your next shot.
GP-31 Grenade Pistol (Secondary Firearm)
The GP-31 Grenade Pistol revolutionized secondary slot utility upon its release. Carrying up to 8 high-explosive impact rounds, it gives players the ability to close outpost spawners without wasting throwable grenades or calling in Stratagems. It allows you to run specialized throwables like Stun Grenades or Smoke Grenades while maintaining full demolition capability for outposts and nests.
A-Tier Helldivers 2 Weapons: Powerful and Versatile Pickups
A-Tier weapons are exceptionally strong weapons that narrowly miss S-Tier due to niche drawbacks, specific ammo constraints, or targeted reliance on team synergy. Using these weapons will yield fantastic results when combined with optimized loadout compositions.
SG-225IE Breaker Incendiary (Primary Shotgun)
The SG-225IE Breaker Incendiary is the ultimate Terminid crowd-control weapon. Spraying high-density incendiary pellets over a wide arc, it ignites entire waves of bugs simultaneously. The lingering Damage-over-Time (DoT) burn effect deals steady heat damage that melts Hunters and Warriors before they can leap into melee range. While recent recoil and magazine count tweaks require ammo conservation, pairing it with a Supply Pack Stratagem yields unrivaled kill counts on the bug front.
R-36 Eruptor (Primary Explosive Rifle)
The R-36 Eruptor functions as a mini support rifle in your primary slot. Firing slow, bolt-action explosive shrapnel rounds, it punches through Medium Armor while shattering fabricator vents and bug holes. Its slow fire rate of 25 RPM makes it unsuitable for close-quarters self-defense, but when paired with high fire-rate secondaries like the P-19 Redeemer, it acts as an incredible primary sniper asset.
APW-1 Anti-Materiel Rifle (Support Sniper)
The APW-1 Anti-Materiel Rifle (AMR) excels against Automaton tactical squads. Operating with Medium-Heavy armor penetration, a crisp variable-zoom scope (75m, 150m, 200m), and high projectile velocity, the AMR can eliminate Automaton Hulks with two swift eye-visor hits. It fires as fast as you can pull the trigger, allowing skilled marksmen to clean out Devastator patrols before combat alarms are raised.
EAT-17 Expendable Anti-Tank (Support Rocket)
The EAT-17 Expendable Anti-Tank offers maximum anti-armor burst potential with zero recovery punishment upon death. With a ridiculously low Stratagem cooldown of 70 seconds, you can call down two single-use rocket launchers every minute. Delivering 650 heavy explosive damage, a quick shot to a Charger’s leg strips away the outer shell, exposing soft flesh to basic primary fire.
P-19 Redeemer (Secondary Machine Pistol)
Boasting a rapid fire rate of 1100 RPM, the P-19 Redeemer is the supreme defensive sidearm when running slow, long-range primary weapons like the Eruptor or Dominator. When bugs burst into your personal space, switching to semi-auto or full-auto burst fire with the Redeemer buys immediate breathing room with high burst DPS.
B-Tier Helldivers 2 Weapons: Solid Front-Specific Choices
B-Tier options feature solid statistics but are often held back by noticeable recoil, limited ammo capacity, or specialized usage rules. While not universally overpowered, they perform admirably when built around properly.
BR-14 Adjudicator (Primary Battle Rifle)
The BR-14 Adjudicator received significant buff patches that elevated it into viable territory. Featuring Medium Armor penetration, high damage per bullet (80 physical damage), and full-auto capabilities, it drops tough targets quickly. However, its violent vertical recoil demands crouching or using engineering armor perks that reduce recoil while prone.
R-63AR Liberator (Default Primary Rifle)
The baseline R-63AR Liberator assault rifle is remarkably dependable. Offering balanced stats across damage (60), recoil (15), rate of fire (640 RPM), and magazine size (45 rounds), it serves as a steady benchmark. While it lacks medium armor penetration, its clean sightlines make it reliable for clearing standard infantry targets.
FAF-14 SPEAR (Support Launcher)
The FAF-14 SPEAR utilizes a lock-on targeting system capable of destroying Bile Titans, Automaton Towers, Tanks, and Factory Striders from extreme distances. When the targeting mechanism locks correctly, its damage output is unmatched. However, environmental fog, terrain obstructions, and erratic line-of-sight bugs can occasionally stall lock-on locks, preventing it from reaching consistent S-Tier status.
FLAM-40 Flamethrower (Support Firearm)
The FLAM-40 Flamethrower is a devastating bio-clearing option against bugs. Delivering continuous flame cone damage that bypasses armor mechanics by directly damaging internal body hitboxes, it can roast Chargers in seconds by focusing flame on a single leg. However, high risk of self-immolation and absolute zero utility against Automaton gunlines restrict its deployment to bug-infested planets.
C-Tier and Niche Weapons: Avoid in High Helldive Difficulty
C-Tier weapons suffer from underwhelming damage scaling, excessive recoil penalties, or direct functional overshadowing by superior alternatives. In Level 9 Helldive and Level 10 Super Helldive operations, taking these weapons increases mission failure risks.
SG-8S Slugger (Primary Shotgun)
Once an elite primary rifle, balance nerfs heavily stripped the SG-8S Slugger of its signature stagger force and destruction radius. While it retains Light-Medium armor penetration, its single-slug reload and reduced precision make the JAR-5 Dominator superior in every combat metric.
MP-98 Knight (Submachine Gun)
Exclusive to Super Citizen Edition supporters, the MP-98 Knight shoots at a blazing 1380 RPM. Unfortunately, this fire rate drains its small 50-round magazines in under two seconds while throwing muzzle climb into the sky. Its abysmal ammo economy makes it a poor pick during sustained defensive sieges.
LAS-7 Dagger (Secondary Laser Pistol)
The LAS-7 Dagger secondary laser pistol suffers from negligible DPS output. While it theoretically offers infinite ammunition on heat management, its beam takes far too long to kill basic Scavengers or Troopers compared to quick tap-firing with the Redeemer or Senator revolver.
Faction-Specific Loadout Optimization for Automaton and Terminid Wars
Winning in Helldivers 2 requires tailoring your inventory to the faction you face. Armor mechanics, weak spot designs, and combat ranges vary drastically between the Automaton Legion and the Terminid Swarms. To maintain high performance, check out our guides on optimizing your best PC frame rate settings and general PC performance tweaking so high enemy counts don't lag your aiming response during intense firefights.
Optimized Terminid Bug Front Loadout
The Terminid swarm relies on rapid melee swarms, flank rushes, and heavily armored behemoths like Chargers and Bile Titans. Your loadout must prioritize high mag-capacity primary weapons with fire/explosive utility alongside heavy anti-tank support weapons.
- Primary: SG-225IE Breaker Incendiary or LAS-16 Sickle
- Secondary: GP-31 Grenade Pistol (for fast bug hole clearing)
- Throwable: G-16 Impact or G-23 Stun Grenade
- Support Weapon: LAS-99 Quasar Cannon or EAT-17 Anti-Tank
- Backpack Stratagem: SH-32 Shield Generator Pack or Guard Dog Rover
Optimized Automaton Bot Front Loadout
Automaton battlefields feature heavy ranged artillery, rocket salvoes, and precision weak spots. You need Medium Armor Penetration, sniper-grade optics, high stagger force, and rapid cover usage to survive.
- Primary: JAR-5 Dominator or PLAS-1 Scorcher
- Secondary: P-19 Redeemer or P-4 Senator
- Throwable: G-23 Stun Grenade (locks Hulks in place for easy eye weakspot hits)
- Support Weapon: AC-8 Autocannon or APW-1 Anti-Materiel Rifle
- Backpack Stratagem: Autocannon Ammo Pack or SH-20 Ballistic Shield (if running One-Handed weapons)
Key Weapon Mechanics: Armor Penetration, Stagger, and Heat Management
To master high-end weapon selection, you must understand Helldivers 2's underlying mathematical combat systems detailed across the Helldivers Official Wiki.
Armor Classes & Penetration Multipliers
Every enemy armor plate and player weapon operates on numerical Armor Rating values scale from 0 to 10:
- Light Armor (Class 1-2): Unarmored bug bellies, basic bot Troopers. Weapon class 1 penetration deals 100% full damage.
- Medium Armor (Class 3-4): Devastator chests, Hive Guard frontal heads, Charger unarmored rear. Requires Class 3 weapon penetration (Dominator, Autocannon) to deal full damage; Class 2 weapons suffer 50% damage deflection penalties.
- Heavy Armor (Class 5-6): Charger head plating, Hulk front armor, Bile Titan chest. Basic primary weapons reflect off completely with a red shield icon. Only Class 5+ Anti-Tank launchers (Quasar, EAT-17, SPEAR, Recoilless Rifle) can penetrate or strip this armor.
Durable Damage Mechanics
In addition to basic health, larger enemies possess a metric called Durable Health Percentage. Standard assault rifle bullets deal only 10% to 20% of their base damage against durable parts (such as a Charger's squishy butt or a Bile Titan's sac). However, explosive weapons like the PLAS-1 Scorcher, R-36 Eruptor, and AC-8 Autocannon deal 100% full damage against durable body parts. Selecting weapons with high Durable Damage stats is crucial for efficient endgame combat, much like refining an endgame build optimization strategy.
By tailoring your loadout around the S-Tier and A-Tier weapons in this tier list, matching armor penetration levels to your target faction, and communicating secondary demolition roles with your squad, you will master Helldive difficulty operations and spread Managed Democracy across the galaxy.
