Pokémon: Let’s Go, Pikachu and Let’s Go, Eevee! both are compatible with Pokémon GO, which lets you bring Pokémon from the mobile game into the console title. To transfer and access these characters, you will head to the GO Park. You can use your own Pokémon GO account, as well as connect accounts belonging to your friends and family.
Pokémon: Let’s Go, Pikachu and Let’s Go, Eevee!’s GO Park is a Fuchsia City complex with multiple functions. There are 20 individual GO Parks in the complex, with each one able to hold 50 Pokémon. Once you transfer a character from Pokémon GO, you have to catch it again in the GO Park to use them.
Details on Pokémon: Let’s Go, Pikachu and Let’s Go, Eevee! Candy details were also revealed. You can use these items to raise stats. Playing a minigame in the GO Complex Play Yard (which seems to involve having 25 of the same type of Pokemon), transferring Pokémon to Professor Oak, walking with Pokémon stored in your Poke Ball Plus in the real world will help you earn them.
Here is the trailer looking at the GO Park. It also shows off the three legendary bird Pokémon, Articuno, Zapdos, and Moltres.
Pokémon: Let’s Go, Pikachu! and Let’s Go, Eevee! release on November 16, 2018 for Nintendo Switch.
