As you'll see in the brand new trailer above, the new games will feature a brand new area called 'Ramanas Park'. Described as "an expansive new facility", Ramanas Park will allow you to encounter a variety of Legendary Pokémon.
From the sounds of things, getting to Ramanas Park is no easy task – you'll need to have entered the Hall of Fame (which means you'll need to have defeated the game's Elite Four), and you'll also need to explore Sinnoh for special slates.
Inside the rooms of Ramanas Park are pedestals, and it’s said that if you insert the corresponding slate into a pedestal, a Legendary Pokémon will appear.
It’s unclear exactly how these slates can be obtained, so you’ll have to do some research as you explore the Sinnoh region.
It's been confirmed that Mewtwo and Rayquaza will be available, and some Legendary Pokémon will be exclusive to particular versions. Raikou, Entei, Suicune, and Ho-Oh can all be found in Brilliant Diamond, while Articuno, Zapdos, Moltres, and Lugia can be found in Shining Pearl.
As for the slates? Well, we think long time fans will get a kick out of their designs:
Pokémon Brilliant Diamond and Shining Pearl launch on Nintendo Switch on 19th November, and pre-orders are available now. To explore Ramanas Park, you'll need to update your game with a patch that's set to launch tomorrow, ahead of the games' release.
