This mod was also known as Nova Upgrade. During further development most of the Tasks of Nova Upgrade were integrated into NTP, which is however mostly a translation project that translates Freespace campaigns into several languages. Right now, NTP gives translations for FreeSpace 2 from English into French, German, Italian, Japanese, Polish, and Spanish. The old Nova Upgrade releases can also still be found here which are bugfixes, so that the campaign can be played through with then-current builds and mediavps.
