The expansion will feature new story content, characters, Pokémon (including version exclusives and Legendaries), Gigantamax forms of existing Pokémon, and gyms.
The Pokémon Direct livestream presentation announced on Thursday that the Pokémon Sword and Pokémon Shield Nintendo Switch role-playing games are getting two expansions.
The games are set in the Kanto region of the first Pokémon games, and are specifically based on 1998’s Pokémon Yellow: Special Pikachu Edition.
The Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee! games, the franchise’s first games for the Nintendo Switch, shipped in November 2018.
