📋 About This Mod
Description
This mod adds weapon inertia. As a part of Project B42, this feature can now be released separately thanks to new functions by JazzIsParis.
Now with customization! Though still no movement inertia.
Pics don't really explain what this mod does exactly, so that's why there's only one for header. These videos should explain it well enough:

This mod requires an edited skeleton.
As of version 1. 0, this skeleton is provided wholly by Compatibility Skeleton, meaning any other mods which change the skeleton will need to get their changes merged in to that in order to be compatible with Inertia.
If you have any mod compatibility requests, I suggest you direct them towards the author of both your desired mod, and Compatibility Skeleton.
Just install and play the game.
Check the config to tune the mod to your preferences.
Could be unstable, due to the very nature of the mod - we never tried before to mess with meshes directly, nobody knows what's going to happen. This seems to have been proven false. Over the years, mods have made use of these functions with no issue, so I think it's safe to say the mod is pretty stable.

Installation
Install required mods first. They are essential and without them – this mod will not work.
"Weapon Inertia" mod installs like any other mod, manually or using a mod manager.
I recommend the latter for easy uninstallation.
Un-installation
Same as installation, in reverse.

B42 Weapon Inertia adds realistic weapon sway and momentum to Project Zomboid, making firearms feel heavier and more dynamic. With nearly 20k endorsements and 2.1M downloads, it's a highly popular animation mod for players seeking immersive combat. Part of the Project B42 series.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Massive community approval—nearly 20k endorsements and 2.1M downloads prove it's a must-have.
- Simple, focused mod: does one thing (weapon inertia) and does it well.
- Part of the Project B42 series, so it's likely polished and integrated with other B42 mods.
⚠️ Cons
- Last updated July 2026—if you're on an older game version, compatibility might be an issue.
- Weapon inertia isn't for everyone—if you prefer snappy, arcade-style aiming, this might feel sluggish.
For Project Zomboid players who want more realistic gunplay and immersive weapon handling. If you're into hardcore survival sims and appreciate subtle animation details, this is for you. Skip if you prefer fast, responsive combat without extra sway.
💡 Beginner Tips
- Since it's part of Project B42, check if you have other B42 mods installed to ensure they work together.
- Test the inertia in a sandbox game first to see if the sway feels right—you can adjust settings if needed.
- If you're using a mod manager, enable this mod after other animation mods to avoid conflicts.
