I played around with the noclip feature a little. It sure messes up the cutscenes :p

I got to go in and play around while Chewbacca was holding off the renegades. I also found an extra Chewie out on a ledge.

To much fog in the other section to see anything but I did find some extra stuff in a hard to get area. I didn't post that on my site so no spoilers are exposed.
