Do I have to unlock the elevators in order?

star-wars-tiny-death-star

In tiny death star, do I have to buy all the elevators to unlock the next one, or can I somehow unlock them all? I would not like to waste bux on elevators that I am upgrading away from immediately.


Solution 1:

From what I gathered they unlock one elevator at the time. I spent months playing Tiny Tower and the game dynamics is very similar here, so although I started building my death star yesterday, I upgraded my elevator and then it unlocked the next upgrade for 75 bux :-)

UPDATE: I upgraded to the elevator for 75 bux and it again unlocked the next lift for 125, again only the one.
