Right now, this game has two secret locations that are covered by question marks in the early goings. These locations are Asgard and Pandora, and both will remain locked even once you discover what their names are. The following Billionaire tips, as you’ll see, tell you just what you should do to unlock these secret spots.
It is easier to unlock Pandora than it is to unlock Asgard, but it may still take some time before you’re able to unlock it. You’ll have to buy all the single negative threat buildings in the in-game world, namely Noah’s Ark, Community Center, Botanical Garden, Charity Center, Search and Rescue, Wildlife Foundation, Public Library, Museum of Science, Recycling Megaplex, Blue Energy Tower, and Eden. And no, you don’t have to upgrade those buildings to Level 5 like what some have speculated.
Just as a warning, there is a reason why we named Eden last among the single negative threat buildings in the above tip. That’s because it is very, very expensive, and will have you paying to the tune of 1,500 crystals, crystals being the game’s premium currency. You’d be best advised to keep watching ad videos for free gems, and watch as many of them as possible. You also have to be logged in every day so you can collect those gems and add them to your stash.
As for Asgard, you have to get the four highest-tier buildings in the game, and after that, upgrade them till they reach Level 10. These buildings are Avalon, El Dorado, Mountain of the Eye, and Underwater City.
Some have claimed that you also need Area 48, the Dinobot Museum, and the Imperial Star in order to unlock Asgard. Fortunately, that isn’t true, though it’s still a good thing to have those buildings, so that they can earn you more money if you’ve got them, and enough money for you to actually purchase them. Bear in mind that you also need to have all the negative threat buildings in order to make the most out of these buildings, and that you should sell any building that may jeopardize your threat level.
