Heh. Been a long time since I played JK last. But, having lost the Jedi Academy CD (slaps self in face) I may need to. As for getting good, the rBots are great for that. I can't beat them myself, at least not easily! But yeah, we may play yet.
And I think those are in the JK Mods section. I don't know why the link includes 'levels'. But it is in the Mods section.
