FreeSpace 2 Source Code Project
Some notable original mods and campaigns have been created, such as "Wings of Dawn" which takes place in an anime-style world, and "Blue Planet" which offers a continuation of "Freespace 2", telling of a civil war between Earth and the GTVA. "The FreeSpace Port", sometimes called FSPort, ports the original "Descent: FreeSpaceThe Great War" to the "FreeSpace 2" and SCP engine with many graphical enhancements, and serves as a base for many mods set in the FreeSpace: Great War era, such as "Shrouding the Light" and "Awakenings". "Silent Threat: Reborn" similarly ports the "Silent Threat" expansion for Descent: Freespace into the Freespace 2 SCP engine.
Parallax Software
On December 29, 2015, it was revealed in a GOG.com forum post that Parallax Software still exists and owns the copyrights to "Descent" and "Descent II". Due to a royalties dispute with "Descent" and "Descent II"s publisher, Interplay, where Parallax is claiming that since 2007 they have not been paid any royalties from the sales of "Descent" and "Descent II", Parallax terminated the 21 year sales agreement with Interplay, so Interplay no longer has the rights to sell "Descent" and "Descent II".
