Helldivers 2 R-36 Eruptor Build, Attachments, Vs Crossbow

The R-36 Eruptor is a bolt-action explosive rifle in Helldivers 2 that functions more like a portable cannon than a traditional primary weapon. It is unlocked on the second page of the Democratic Detonation Premium Warbond.

Key Features & Stats

• Ammunition: Fires jet-assisted shells that explode on impact, releasing shrapnel.
• Armor Penetration: It is one of the rare primary weapons with heavy armor penetration, capable of damaging most enemy types.
• Maximum Range: Rounds automatically air-burst after traveling approximately 180 meters.
• Utility: Can destroy Bug Holes, Automaton Fabricators (by hitting vents), and Illegal Broadcast Towers.

Performance vs. Factions

• Terminids: Effective for clearing groups of small bugs and medium targets like Hive Guards and Spewers. It can even bleed out Bile Titans by shooting their unarmored undersides.
• Automatons: Excellent for sniping Devastators and can destroy Gunships in two hits to the engines. It can two-shot a Hulk's visor with precision.
• Illuminate: Highly effective against flesh mobs and can one-shot many shielded units.

Combat Tips & Loadouts

1. Mind the Distance: The explosive radius is large; firing at enemies closer than 7-10 meters will likely kill you.
2. Pairing: Because of its slow fire rate, it is best paired with a high-rate-of-fire secondary like the P-19 Redeemer or a support weapon like the Stalwart or Machine Gun to handle close-range "chaff".
3. Ergonomics: Use armor with the Peak Physique perk to improve the weapon's slow handling and aim speed.
4. Reload Trick: You can technically skip part of the bolt-action animation by quickly switching weapons after a shot, though this requires precise timing.

Building around the R-36 Eruptor requires balancing its massive explosive power and utility (like closing bug holes/fabricators) against its slow fire rate and poor close-quarters performance.

1. The "Crowd Clear" Build (Best for Bugs/Illuminate)

This setup uses the Eruptor as a "secondary" utility weapon while relying on a high-RPM support weapon for self-defense.

• Support Weapon: MG-43 Machine Gun or M-105 Stalwart (use the Stalwart for mobility or the MG for medium armor).
• Secondary: GP-31 Grenade Pistol or P-19 Redeemer to bail out of close-range ambushes.
• Backpack: AX/AR-23 Guard Dog Rover to thin out chaff enemies that get too close.
• Armor: Any with the Peak Physique passive (improves weapon handling/ergonomics) or Fortified (reduces explosive self-damage and recoil).

2. The "Anti-Armor Sniper" Build (Best for Bots)

Focuses on long-range precision and taking down medium-to-heavy targets from safety.

• Support Weapon: LAS-98 Laser Cannon or GR-8 Recoilless Rifle for infinite-range utility against Gunships and Hulks.
• Secondary: P-4 Senator for reliable, punchy backup.
• Grenade: G-23 Stun Grenade to freeze Heavies in place for an easy Eruptor eye-shot.
• Stratagems: Eagle Airstrike and Orbital Precision Strike for clearing outposts and tanks.

3. Key Weapon Attachments

If you have access to weapon customization, prioritize these to offset the Eruptor's sluggish feel:

• Underbarrel: Vertical Foregrip (-25 Vertical Recoil) or Angled Foregrip (+5 Ergonomics).
• Optics: Stick to the high-magnification scopes to leverage its long-range accuracy.

Pro Tips

• Distance is Safety: Never fire at an enemy within 5–10 meters; the explosive shrapnel can and will kill you.
• Utility King: Use the Eruptor to destroy Bug Holes and Automaton Fabricators from a distance, saving your grenades for combat.
• Reload Trick: You can cancel the bolt-action animation by quickly swapping to your secondary and back, though recent patches have adjusted the timing.

Helldivers 2 Eruptor Vs Crossbow

In Helldivers 2, choosing between the R-36 Eruptor and the CB-9 Explosive Crossbow depends on whether you value raw, heavy-hitting power at a distance or mobile, versatile utility.

Take the Eruptor for: Automaton missions where you need to snipe Devastators from a distance or Illuminate missions where shrapnel shreds flesh mobs. Pair it with the Stalwart to handle close-range swarms.

Take the Crossbow for: Bug missions where you need to stay mobile, or when using a Ballistic Shield against bots. It excels as a primary for players who carry objective items (like SSSDs) since it stays usable while carrying.
