How do you unlock all the levels on Tony Hawk’s Proving Ground?

It seems like the Internet only has a cheat code for three levels, the air and space museum, the outdoor park, and something else. Anywhere there is more, so how do you unlock them? Is there a cheat or do you have to complete the story mode?
