That kit had me stumped for a while, but I finally worked it out. Okay, so I asked in the official LSW topic, but whatever.
Well, I'm approximately 96% through the game. Because I rock like that. Anyways, I just have a couple of minikit special levels to do (ESB and ROTJ) and ROTJ Super Story to do (which I gave up on when the droids wouldn't go and press the buttons on the other half of the gate section on Endor...), and I still haven't got around to getting ghost Obi-Wan yet. I also need a few more extras, most of them being the score multipliers. I've been taking my time, and so I'm up to 30 hours gameplay.
I should get a job or something...
So yeah. And I'm pretty proud that I didn't use a guide at all.
