In March 1997 in North America and mid-1997 in Europe, the PlayStation version of "Descent II", known as "Descent Maximum" was launched. Instead of a straight port, it included new levels (for a total of 30), textures and FMV over the PC version of "Descent II". On October 29, 1997 "Descent I and II: The Definitive Collection" was released. A compilation, it contains the full version of "Descent", "Descent II" and "Descent II: Vertigo Series". In 1998, "Descent II" was released in a standalone jewel case (as opposed to a box) by SoftKey, with an AOL trial offered on-disc. Also in 1998, the "Descent II" source code, like that of "Descent" before it, was released to the general public under a copyrighted proprietary license, leading to community source ports. It was later ported to RISC OS by R-Comp Interactive, and the port debuted at the annual Wakefield Acorn RISC OS Show on May 19, 2001.
