There appears to be a broken door in uptown: use the Main Street Central Building entrance, then enter the first building on the right. The door on the left will give you the e to enter option but will not let you use it.
How did this game get even 3and a half stars? It IS fun and all, but every top comment is negative, its completely pay to win, and it wont connect half the time!
I think that he comment on the level select mode ("IF you can not go farther start with the first waves...") only really applies to pleayers with low level and money because when u have high level its better to play higher lvls over and over because they get u most money.
