I know there was a file called NWP 19.2 (New Weapon Project)
Here's some link

Don't know if this NWP file is compatible with the STEAM version.
I myself has two disc version - The old for XP and a newer one for Vista, 7 and 10. and this NWP 19.2 worked fine with the latest.
I had 3.2 something to my older FC version.
