Raven just Open Sourced Jedi Outcast and Jedi Academy.

Jedi Outcast and Jedi Academy were successors to the original Jedi Knight game which was developed and published by LucasArts itself and released in 1997 as a sequel to the popular Star Wars: Dark Forces, the first official first person shooter set in the Star Wars universe. In a statement given to Kotaku Australia, a Raven spokesperson said: "Raven is sad to hear about the closing of LucasArts today, we respected them and enjoyed working with them over the years". The company also said it was releasing the source code for its two games "for people to enjoy and play with" as a gift to the fanbase of the Jedi Knight games and as a tribute to LucasArts.

The source code for both Star Wars Jedi Knight II: Jedi Outcast (originally released in 2002) and Star Wars Jedi Knight: Jedi Academy (from 2003) is available from SourceForge. Both code releases comprise single player and multiplayer components, including the server components used to run matches over a LAN and over the internet. Both games run under Windows and Mac OS X, but a community port to Linux seems likely as the id Tech 3 engine has already been ported to the platform.
