What is the Fallout 4 Script Extender?

Fallout 4 Script Extender, also known as F4SE or FOSE is a community made modder’s resource that expands the scripting capabilities of Fallout 4. It’s required for a few mods that currently exist.

I currently have two mods installed that require me to use F4SE. These mods are “Place Everywhere” which allow me to build settlement objects anywhere I want, such as in side of walls and terrain.

The second mod is Achievements, which allows me to keep earning achievements whilst using mods. Bethesda decided to disable gaining achievements a whilst back for some unknown and bizarre reason.

How to install Fallout 4 Script Extender

Installing F4SE is a ridiculously easy task, but it can seem a bit confusing to anyone who has never done it or is slightly new to the modding world.

  1. To start, head to the F4SE website.
  2. Now you can choose to either use the installer, which will place all the files where they need to go automatically. Or you can download the 7z archive if you’re not someone who trusts running executable files.
  3.  If you’ve chosen the installer, just go through the setup and choose your Fallout 4 directory. It’s usually C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 but varies person to person.
  4. If you’ve chosen the 7z archive, you’ll receive a ZIP File. All you need to do is highlight all of the files inside, and drop them into your Fallout 4 Folder. Again, this is usually at C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 but may be different for you. You want f4se_loader.exe to be in the same folder as Fallout4.exe
  5. That’s it. You’ll just need to remember to update the Fallout 4 Script Extender whenever Bethesda updates Fallout 4. To actually use F4SE, you will need to run f4se_loader.exe instead of Fallout4.exe to run the game. Mods that require F4SE won’t run unless you run the game through f4se_loader.exe
