Star Wars: Jedi Knight II: Jedi Outcast (aka JK2, JKO, or JO) is a Star Wars computer game released in 2002. It was developed by Raven Software and published, distributed and marketed by LucasArts in North America and by Activision in the rest of the world. It was released for Microsoft Windows, Apple Macintosh, Nintendo GameCube and Microsoft Xbox. It is powered by the Quake III Arena engine. This game was followed by the very similar sequel Star Wars: Jedi Knight: Jedi Academy. The game was generally well received and is praised for its advanced lightsaber dueling.
Following The Walt Disney Company decision to close LucasArts on April 3rd, 2013, the developers at Raven Software released the source code for the game on SourceForge under GNU GPLv2 licensing. However, the source code for both games disappeared from SourceForge without an explanation. SourceForge later explained that Raven had requested the removal of the code, and it is believed that this was due to the presence of proprietary code that was not intended to be made public.
