"Pokémon Sword" and "Pokémon Shield" were released worldwide in November, but Nintendo is already offering players a massive expansion pass that will add more than 200 collectible monsters to the games and provide hours worth of new areas to explore.

The "Pokémon Sword and Shield" Expansion Pass will be released in two parts - The Isle of Armor and The Crown Tundra. Both parts will introduce new explorable areas with dozens of unique Pokémon that can't be found in the main game. Players who don't purchase the expansion pass will still be able to trade for those Pokémon or transfer them from other games once the updates are released.

Here's what to expect.
