📋 About This Mod
WHAT IT DOES
It adds two guns:
1. A unique oversized pistol, based very loosely on Alucard's . 454 Casull gun. It is not an exact copy, though, because that's not even possible: the gun is drawn differently every time. Just in the first episode alone, it has three different shapes for the slide, for example. So I've done my own take on it, also constrained by the game's animations and how it sits in the hand and such.
It has a 10 inch barrel (in the anime it says 10 inch on the side of the gun in the small print), and weighs 12 pounds, including the ammo. The barrel is pretty accurately 13mm caliber, to match the number stated by Alucard himself. (Real . 454 ammo is only 11. 5mm.) It ejects custom brass that's 35. 1mm long (same as a . 454 Casull round), wide enough for a 13mm bullet, and rimless like the ejected casings in the anime.
It is fully animated, using the standard game animations. I also at least tried to make it look a little old. The slide and frame are heavily scratched and in places a little stained, especially darkened around the places you'd put your hands on it. Like for example the rear part of the slide, which you paw every time you reload. It also has some faint traces of incipient rusting, especially around where Alucard puts his mouth on it.
It needs 10 Strength and 100 skill for the full accuracy and damage, although at least the strength requirement can be fudged with perks and implants. You can lower the Str requirement by 2 points with a perk, you can get +2 Str with power armour, plus another point with a perk and another point with an implant, so basically an extreme build could meet the requirements while having only 4 Str.
For ammo, it uses . 454 Casull ammo from either the CASE mod or the CaliberX mod. Optionally, if you can't or won't get CASE or CaliberX to run, a vanilla version exists that shoots standard 12. 7mm ammo instead. (Alucard does state it shoots a 13mm bullet, and I figure 12. 7mm is close enough for government work, if all else failed.)
It's repaired with 10mm pistols, or rather, with anything you could repair a 10mm pistol with. Repair kits and a certain perk should still work, as you'd expect.
The gun is accurate, has high range, has high damage per shot, does double damage to limbs and has twice the chance to crit. On a crit, it knocks down. For damage and DPS, it's about on par with the Ranger Sequoia from the base game with the cowboy perk, and it also has a low rate of fire and it IS heavy, so I don't consider it particularly unbalanced.
Also, this is not a silent gun. It's very loud, and it has a big muzzle flash. Don't be surprised if every fiend within half a mile suddenly notices you.
2. A shorter version in 10mm, called the "Baby Joshua", with only an 8 inch barrel and 10 round magazine. It's no
Adds an oversized semi-automatic pistol inspired by Alucard's firearm from Hellsing, plus an optional non-canon 'mini' version. A niche cosmetic weapon mod for Fallout: New Vegas fans of the anime, with 365 endorsements and last updated in 2015.

💡 Beginner Tips
- Since the mod is from 2015, check if your game version is compatible — if you use mod managers like NMM or Vortex, install manually if auto-install fails.
- The 'mini' version is non-canon, so if you want the authentic Hellsing experience, stick with the full-size version.
- Look for the weapon in the game's leveled lists or console commands — the description doesn't specify, so you may need to use the console to spawn it.
