Fallout 4 Script Extender (F4SE) Screenshots

Fallout 4 Script Extender (abbreviated F4SE) is intended for modification developers that extend the capabilities of Fallout 4 scripts. It does not modify executable files on disk, so there are no side effects.

F4SE only supports the latest version available on Steam, and only it. When a new version is released, the file will be updated here. If this does not happen, wait a bit. 

This version is compatible with the game version 1.10.163. You can not take into account any additional numbers after these in the version indication, they do not affect compatibility in any way.

This software package is necessary for the correct operation of a large number of mods and is recommended for installation by anyone who actively uses third-party mods.


Unzip the contents of the “F4SE – 0.6.21” folder if you have a regular version of the game or “F4SE for VR – 0.6.21” in the game folder.
