Niantic has announced that level 40 players of Pokemon Go can now begin exporting their captured monsters from the mobile game into Pokemon Sword and Shield via Pokemon Home.
Transfer of any creature will also unlock a special Melmetal in Pokemon Home that can use the Gigantamax ability in Pokemon Sword and Shield.
You can read up on more details on how the transfer works over here on the Pokemon Go official website.
The functionality is available in Pokemon Go on Android and iOS now for Level 40 trainers, and is expected to roll out to other players over the next few weeks.
