New Vegas Script Extender (NVSE xNVSE)

The New Vegas Script Extender, or NVSE for short, is a modder's resource that expands the scripting capabilities of Fallout: NV. It does so without modifying the executable files on disk, so there are no permanent side effects.

Once installed, no additional steps are needed to launch Fallout New Vegas with NVSE's added functionality. You can start the game using NVSE from nvse_loader.exe

xNVSE is compatible with the Steam and GOG versions of the game.

Not supported: German No Gore, Xbox Gamepass, Epic Games Store, and Bethesda.net versions.

For Epic Games Store version owners, consider using lStewieAl's patcher to make that version work with xNVSE.
