📋 About This Mod
Fallout 4's Gatling Laser always disappointed me, primarily because of how poorly it handles its ammunition source. You're either forced to maintain only a single fusion core in your inventory, or will inevitably end up with 50 different fusion cores in your inventory that all have differing charge levels.
To address this issue, I created this mod: any time you equip a weapon that uses standard fusion cores, it'll apply a special weapon mod to convert it to use "partially depleted" fusion cores, and will convert standard fusion cores into partially depleted fusion cores as needed. In this way, you'll only ever discharge one fusion core at a time, and won't end up with loads of slightly discharged fusion cores cluttering up your inventory.

This also includes a fix for magazine capacity, to avoid the thing where you need to unload then reload the same fusion core back into your gun part-way through its charge, and an option to disable the spin-up/charge time on a fusion core weapon to make it a little more practical to use.
-- Ammo Recycling --
Perhaps the main drawback of this system is that it disables normal manual reloading. As an alternative, this mod offers a way to recycle your ammunition. The way this works is very simple - when you use the aid item in your inventory, your current (e.g.) Partially Depleted Fusion Core will be destroyed, and its remaining health will be converted into Recycled Fusion Core Charges. For each 0. 1% of health your ammunition has remaining, you will receive 1 Recycled Fusion Core Charge; as soon as you collect 1000 of these, they will automatically be recycled into a full ammunition item that you can use again.
In case you want to discourage your own Chronic Reload Syndrome, you can also set a penalty for this system via the holotape. Recycling efficiency is 100% by default, so that e.g. a 25% charged Fusion Core will recycle into 250 Recycled Charges. If you were to set this to 75% instead, you'd receive 187 charges, or at 50% 125 charges, and so forth.
For convenience, I recommend assigning your item to a hotkey. If you don't use it already, I also recommend registrator2000's Hotkeys mod, so that you can assign this item to any key or key combination that you'd like.
-- Config --
The first time you equip a compatible weapon, you'll get a config holotape added to your inventory. Provided you don't have a holotape already, you can also craft one at a chem bench. Its options are as follows:
- for manually configuring your current weapon, particularly if automatic setup doesn't work properly.
- If GLAF doesn't corre

✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust (3,135 endorsements, 527k downloads)
- Fixes a genuinely annoying vanilla mechanic without overhauling the whole game
- Configurable, so you can tune it to your preferred balance
⚠️ Cons
- Last updated in 2021 — may not be compatible with the latest Fallout 4 patches or DLC
- Requires script extender (F4SE) and likely MCM for full configuration, adding setup steps
- Only affects Gatling Laser — if you wanted broader fusion core fixes, this won't cover other weapons
For Fallout 4 players who love energy weapons but hate how the Gatling Laser chews through fusion cores. If you're a modded playthrough veteran comfortable with F4SE and MCM, this is a must-have. Skip if you rarely use the Gatling Laser or prefer a complete overhaul of ammo systems.
💡 Beginner Tips
- Install F4SE first and launch the game through f4se_loader.exe, not the default launcher, or the scripted mod won't work.
- Use a mod manager like Vortex or Mod Organizer 2 to handle the file structure and avoid overwriting issues.
- After installing, check the MCM in-game to adjust the fusion core drain rate to your liking — start with a moderate setting to see how it feels.
