Walls, objects and bunkers are no longer absolute protection. You use now

What you shoot, what you penetrate, really matters.

Module Overview

This mod introduces a fully dynamic engine-level bullet penetration system to Fallout 4, powered by F4SE.

Each projectile hit is evaluated in real time based on ammunition type, weapon type, material properties and object thickness.

Bullets don't just stay on invisible obstacles, but penetrate walls, bunkers and objects as physical conditions allow.

Afterwards, the projectiles continue to be used, but with reduced range, penetration, and damage, ensuring that the penetration doesn't feel unfair or overly powerful.
