This mod makes sure that game’s script is sufficiently extended letting hundreds of mods to work at the same time. NVESE does so without modifying the executable files on disk, so there are no permanent side effects. It is a modder’s resource expanding the scripting capabilities of Fallout: New Vegas. Looking for bigger and complex Fallout: New Vegas mods, you are required to use New Vegas S cript Extender (NVSE).
