Speargun Gas AND Stun Payload 2026-09-29

A Mod for Helldivers 2
Speargun Gas AND Stun Payload akl_mod_preview_image
Adds a native in-game Programmable Ammo menu to the S-11 Speargun, allowing you to switch between the default Gas payload and a new Stun payload by holding Reload.

Great Counter to War Striders by the way.

Ammo Modes​

GAS — Default​

  • Uses the Speargun's original gas payload
  • Native Gas projectile: Projectile Type 125
  • Native Gas explosion: Explosion Type 97
  • Preserves the normal gas cloud and gas effects
  • Retains the Speargun's normal direct-hit damage

STUN ROUNDS — Alternate​

  • Uses the same flying spear projectile behavior
  • Alternate projectile: Projectile Type 300
  • Uses the native StunMassive impact effect
  • Stun explosion: Explosion Type 335
  • 50 Stagger
  • 0 Push
  • 0 Blast Damage
  • 0 Durable Blast Damage
  • 0 Demolition Force
  • Preserves the native stun/status behavior
  • Will stun War Striders
  • Illuminate and Terminid balance testing is still needed
The stun explosion itself is intentionally harmless. Damage still comes from the spear's normal direct impact.

Base Spear Stats​

Both ammo modes retain the Speargun's normal direct-hit characteristics:

  • 650 Standard Damage
  • 275 Durable Damage
  • AP5
  • Same spear model
  • Same projectile speed
  • Same gravity and flight behavior
  • Same direct-impact damage
Only the payload effect changes between Gas and Stun.

Programmable Ammo​

The ammo selector uses Helldivers 2's native Programmable Ammo system, similar to other weapons with selectable ammunition.

Hold Reload and select:

GAS

or

STUN ROUNDS

No separate keybind or external menu is required.

Testing​

I haven't fully tested every enemy interaction yet, particularly against the Illuminate, so feedback and additional testing results are welcome.

Compatibility​

Disable other Speargun payload mods that modify the same weapon records.

Bingus Shared Loader is required.

HD2Runtime is not required.

An LLM was used to do the bulk of the mod building and reverse-engineering work.

is it possible to just buff the speargun? like giving the gas payload more AOE? like i fire it and the gas covers nothing its so small. is it possible to just be as big as the gas strike or like half that size?
next spear gun update may just increase size to that of a gas grenade, but not increase damage or duration

That’s a great idea! What if we took it a step further and implemented various types of arrows? For example: gas (already included by default), stun (already implemented), arc (like a grenade, but weaker), and fire or explosive projectiles. We could also try a purely kinetic arrow with a stun effect—causing the target to stagger or interrupting their action—but with higher damage.

i have already accidently discover arc payload works. theres alot you can probably do with this weapon, looking forward to messing with it more

hey, since you figured out how to add a new function to a weapon, I was wondering if I could get help with a couple things

1. Adding a 1200rpm mode for the MG43 Standard Machine Gun

2. Adding the Arbitrator's Masterkey Shotgun to the Sta-52

Can you update this mod again? Sometimes it gets overridden by mods that affect the hoverpack or jump pack.
