📋 About This Mod

XM4 RAW

After almost three months of work, the XM4 RAW is ready to release. I’m FINALLY happy with the state the mod is in and I’m releasing it now before I find something else to tweak, change or edit about it… This is probably the most detailed weapons I’ve made, it has the largest ‘support structure’ behind it, if you would. There are new sounds, new meshes, new textures, new activators, a new(ish) bunker for you guys to find it in, new scripts that do lots of clever little things, new (well, edited) explosion effects, and of course, one shiny new weapon for you peeps to shoot bad guys with. The XM4 RAW is a ballistic weapon with an energy kick if you use the right ammo. Version 1. 4 adds a select fire feature to allow you to choose between Full Auto and Single Fire modes. The new version is DLC and NVSE + JIP/LN dependent so you'll need to have those to get it to work. I may make a Non-DLC version if there is interest but a Non-NVSE+JIP/LN version is not possible. The other versions are still 'up to date' as the only change made in version 1. 4 is the addition of Select Fire.

Videos

Here's some videos by commanderxbox and AlChestBreach respectively, featuring the weapon in action, I would like to thank them both for taking the time to review and play with the weapon, thanks guys.

[DISCLAIMER You do NOT have to/aren't supposed to reach through the forcefields to acquire the weapon and its mods as is shown in commanderxbox's video, there is a wall terminal opposite the forcefields that shuts down the fields if you can hack it. Also, Al's video is a perfect example of what the mod looks and acts like when you don't have NVSE and/JIP installed.]

Lore

I have included lore for the weapon in the mod, but in case some things are unclear, here’s a rundown. The XM4 RAW is a prototype weapon designed in a Pre-War USAF research facility located in the Mojave dessert desert. Based on designs provided by the researchers that worked on the X277 "Viper" magnetic Rail cannon, and the pre-existing M4 (Assault Carbine in FNV), the XM4 RAW design was completed just days before the bombs went off. BTW, for anyone wondering about the name, my reasoning is thus:

“’X’ – US Military Designation for experimental weapons –‘M4’ – Name of the weapon being experimented on – ‘R. A. W.’ – Rail Assisted Weapon”

The weapon utilises magnetic rails (Or coils, depending on who you ask, lol) to accelerate a Ferromagnetic bullet, fired from a low power casing, down the barrel to extremely high velocities. This allows the weapon to fire low power, quiet, maintenance friendly rounds that have extr
