A new campaign. It is a sequel to Jedi Knight Academy, Jaden Korr turned to the dark side and stole the scepter.
I consider this mod is one of the best single player mods for Jedi Academy. With a similar duration to JA, the new option to pick up lightsabers of defeated enemies and very exotic types of lightsabers.
The bad is that certain enemies have a ridiculously large health pool, but the mods are usually to be more difficult than the original.
