try buying all of the characters

You've got to get enough Studs in each level. this will build the Tantive IV outside and
unlock a new level!

I have two more carecters left to buy what do I do.

You can unlock it by filling the "true jedi meter" when you get the certain amount of
studs Ex: 60,000+ studs in Kashyyk the meter flashes and that mean you filled it.
