Re: Zeffo: Gone a wrong 'un !!
There is a cave on the beach that will take you to the ice caves. The ice caves have tram cars that will take you to various places. The OTHER tram car with Storm trooper guards will take you right to the hanger (not the one you come out of).
Also, other routes: The tram car that has no guards (there is a big monster nearby) will take you back to the windswept ruins. There is a passage in those ruins that will take you back to the outside the way you came (probe Droid in that passage).
Zeffo is super convoluted but once you figure it out, it's not so bad and you can use the ice caves to get all over the place.
