The latest official release of NVScript, along with full source code, is always available here:

https://github.com/NamelessVoice/NVScript/releases

You can download the latest beta (and non-beta, if that's what's the latest) build of NVScript here - while SS2Tool always installs this, a separate download might come in handy for those with custom/manual installs of SS2. Some wip stuff from the Engineering might require the latest build to work properly, and you can also use it to update the old versions that are included in many mods and fan missions to fix stuff. But, as with everything available here, you should have at least some basic knowledge of SS2 workings if you want to play around, if you don't, you are probably better off downloading the finished stuff from the Mods subforum.

Will attach new builds as they become available.


You also may have to unblock the script file after extracting, see the screenshot.
