📋 About This Mod
What is BallistX and how does it differ?
BallistX is a mod that adds a ballistic trajectory to most projectiles by actually following real ballistic models. That means that unlike other ballistics mods, which only possess static velocity and basic bullet drop for projectiles, projectiles in BallistX will in fact loose velocity over time due to drag and get deflected by wind!
Additionally, BallistX has a damage drop system which is proportional to the velocity. Worth noting is the extensive research went into finding credible values for each ammo type that will influnce the projectile's muzzle velocity and behavior during flight, first of which will also be decided by barrel length and can be easily customized.
It also comes with a plethora of new and optional calibers, each with unique load data and attributes!

✨ Key Features
📊 Pros & Cons
✅ Pros
- Adds a whole new layer of realism for gun nerds who want their shots to actually drop and drift.
- Solid community backing with 369 endorsements and nearly 19k downloads.
- Actively maintained—last updated April 2024, so it's likely compatible with current game patches.
⚠️ Cons
- Requires a mod manager and possibly F4SE or other dependencies, but the description doesn't say which.
- Realistic ballistics can be brutal for casual players—expect to miss a lot more until you learn the new physics.
For Fallout 4 players who crave hardcore realism and want every shot to feel like a real ballistic calculation. If you're a casual shooter who just wants to point and click, skip this—it'll frustrate you.
💡 Beginner Tips
- Use a mod manager like Vortex or MO2 to install and manage load order—this mod likely needs to load after other gameplay overhauls.
- Test your weapon's zeroing at different ranges in a settlement to get a feel for bullet drop before heading into combat.
- Check the mod's forum posts for user-reported compatibility with popular weapon mods, since the description doesn't list any.
