What Starfield Script Extender is

Starfield Script Extender (SFSE) adds scripting capabilities and plugin support to Starfield on Windows. It supports only the latest Starfield version available on Steam; the Windows Store and Game Pass editions are not supported. The official site lists build 0.2.21 for Starfield version 1.16.244. Its changelog includes a plugin manager, a Scaleform menu plugin interface, and preliminary support for custom Papyrus native functions. Installation instructions say to use Steam or the installer, copy the DLL and EXE files into the Starfield folder—not its Data folder—and launch the game with sfse_loader.exe. The site warns against using anything from the Windows App Store. Updates to Starfield have sometimes meant plugins need recompiling or compatibility data updates. SFSE components use a code signature intended to reduce false positives from virus scanners. The software is free, listed as free. The official site provides a team email and disclaims express and implied warranties.
