Post-EAC rebuild. The loader is gone. This is a manual file swap.​


JAR-5 Dominator: Rechambered​


Ministry of Defense — Procurement Notice

The Ministry of Defense has authorized a field conversion for the venerable JAR-5 Dominator, reconditioning the rifle's chamber to accept the explosive gyrojet cartridges originally developed for the P/40-K sidearm program. Helldivers wielding the Dominator have long prized its stopping power against armored threats but field reports consistently noted the rifle's 15×100mm ammunition lacked the terminal effect required to breach the heaviy enemy armor now encountered across the galaxy.

This conversion corrects that deficiency — and then some. The Rechambered Dominator fires the same rocket-propelled, high-explosive warhead as the P/40-K, loaded behind a hotter and larger gyrojet rocket which drives the round to 380 m/s — more than double the stock round's 180. Heavy armor penetration and explosive fragmentation on impact now with the veloctity and maximum range of a rifle.

Additionally, all JAR-5 Dominator's have been been modified by armorers and are now proper select fires (semi, burst, full automatic).

Managed Democracy demands overwhelming firepower. This conversion ensures it.

— Ministry of Defense, Office of Armaments



Post-EAC stat plan json format. This is no longer a dl_bin swap mod so it doesn't require any merging with other dl_bin swap mods.

WHAT IT DOES
Rechambers the JAR-5 Dominator to the P/40-K Bolt Pistol's explosive warhead. Two ballistic profiles. Optional firing sound.

REGULAR
  • Speed: 380 m/s, up from 180.
  • Range: 532 m. The rocket motor burns out and the round despawns.
  • Arming distance: 7 m.
  • Recoil: about 1.2x stock.
  • Spare magazines: 6.
  • Blast: the bolt pistol's. Full damage inside 1 m, falls off through 6 m, nothing at 7 m.

REALISTIC
  • Speed: 450 m/s. The game stores one speed, so this is the speed after the motor finishes, not the crawl at the muzzle.
  • Range: 360 m.
  • Arming distance: 3 m.
  • Recoil: 0.60x stock. Most of the push happens after the round has left.
  • Spare magazines: 4. Fifteen rounds are still in the gun.
  • Spread: +1 on both cones.
  • Blast: a private copy. Full damage inside 1 m, nothing past 2 m. The bolt pistol keeps its own wider blast.
INSTALL
  • The dl_bin file swap versions will load into any mod manager. They will conflict with any other dl_bin swap mods and you will need a mod merger to reconcile.
  • The statplan versions are compatible with Ordnance and require only Ordnance.

FIRING SOUND
Pick one, or leave it stock. Darktide, Space Marine II, Boltgun, or Necromunda. The stat swap and the sound are independent. Install a profile, then a sound, or use the sound alone.

KNOWN ISSUES
  • The armory still shows the stock Medium text. The Heavy / Explosive tags are not on the card.
  • There is no full-auto, and no SAFE/UNSAFE wheel. Those belonged to the old loader build. They are not in this one.
  • The Space Marine 2 audio file is 3 dB too loud.

v3.4.14 Changelog

Fixed

  • The armory and first-life values were late. The magazine, trait, and recoil tables sit in memory before the entry that identifies the Dominator. A bug in the code that connects them — a function had been declared twice, so the call did nothing — meant those tables waited for a second, much later search. The visible result: a stock first life (6 spare magazines, no SAFE/UNSAFE wheel, no full auto) and an armory card that stayed vanilla until a respawn or a card reopen. Fixed. All values now land on the first life and the armory card is correct the first time it opens, in both Regular and Realistic.
  • Realistic UNSAFE kept the full pistol blast. If the UNSAFE round was built before the 1 m / 2 m blast copy existed, it stayed on the pistol blast. UNSAFE now always fires the tight 1 m / 2 m blast.
Improved
  • Faster, more reliable startup. The mod now walks the game's table headers directly — the same method SHODAN's Stat Editor uses — instead of byte-scanning hundreds of megabytes, so the patch lands within moments of loading.
  • Better logs. Every log line carries a frame number, and internal errors are now reported instead of silently ignored, so problems are easier to pin down.
Known Issues
  • The Space Marine 2 bolter sound effect is 3 dB too loud.

thank god it seems youve worked on the performance problems this had before, and now I don't need to run a seperate concurrent full auto mod alongside yours. Yours is now all in one!! c:

Okay, it's a little unpolished right now and it is NOT compatible with regular mod managers (will have a script install) but I do have a basic version working.

Right now I'm working on getting SAFE/UNSAFE modes and full-auto back on the weapon wheel. Will continue testing but I'll definitely be able to bring this bad boy back if not every previous extra feature it had.

Man, I really miss this mod. It’s like bringing my heavy bolter from Space Marine 2 over to Helldivers.

Without BSL or runtime, how are any of these latest mods supposed to work? Haven't notice any change after the download.

For anyone wanting these and other stat changes back, Shodan Stat Editor works.
