Two big DLC expansions for Pokémon Sword and Shield are on the way this year: The Isle of Armor and The Crown Tundra. Isle of Armor is already out and The Crown Tundra will be coming out on Fall of this year. Since Isle of Armor and The Crown Tundra were officially unveiled, The Pokémon Company has been gradually revealing more details about the expansions in the lead up to their launch. Isle of Armor and The Crown Tundra are bundled together as part of the Pokémon Sword and Shield Expansion Pass, which is available through the Switch Eshop for $30 USD / £27. The expansions cannot be purchased individually.
Game Freak is bringing back a whole array of old Pokémon alongside each expansion. These monsters are being added as free updates, so gamers don't need to own the Expansion Pass to get them; they’ll be able to receive the Pokémon through trades or import them via Pokémon Home even if they don't pick up the DLC. However, the returning Pokémon can only be encountered in the wild if you own the Expansion Pass. In total, more than 200 old Pokémon will be added to Sword and Shield, including practically every Legendary from previous games.
Besides all the returning Pokémon, each expansion introduces new Pokémon to the games. Chief among these are two new legendaries: Kubfu, the mascot of Isle of Armor; and Calyrex, the mascot of The Crown Tundra. The expansions introduce new forms of some older Pokémon as well, including Galarian variants of Slowpoke, Slowbro, and Slowking, as well as Gigantamax versions of Venusaur and Blastoise. The Pokemon Company has also shown off Galarian forms of Articuno, Zapdos, and Moltres, as well as two new Regis: the Electric-type Regieleki and the Dragon-type Regidrago.
The Isle of Armor expansion takes place on the island, which lies off the coast of Galar proper. The isle is home to a Pokémon dojo, where aspiring trainers learn under the tutelage of an old man named Mustard, who is the longest-reigning champion in Galar history and Leon's former mentor. The second expansion for Sword and Shield takes place in the eponymous Crown Tundra, a mountainous region blanketed in snow. According to The Pokémon Company, the theme of this expansion is "exploration." Players will be appointed leader of an exploration team by "a certain person" and will be tasked with investigating the area. In addition to the new Pokémon and locations, each expansion will introduce some new gameplay mechanics to Sword and Shield. The Pokémon Company hasn't revealed too many details about these as of yet. The Isle of Armor expansion is out now, while The Crown Tundra will follow in Fall 2020. Stay tuned for more updates.
