“Raven is sad to hear about the closing of LucasArts today, we respected them and enjoyed working with them over the years, we wish the best for all the talented people who were let go and hope they find good work in studios in the industry. We loved and appreciated the experience of getting to make Jedi Knight II: Jedi Outcast and Jedi Academy for LucasArts. As a gift to the persistently loyal fanbase for our Jedi games and in memory of LucasArts, we are releasing the source code for both games for people to enjoy and play with." said Raven talking to Kotaku Australia.
Both games were made on the Quake 3 engine. Whilst Raven have stated that it may take some work to get the source code working with all of the retail assets, it should be relatively easy for dedicated modders to add or improve upon the single player portion of the game.
