Today, Trainers will be able to get their hands on special codes to receive Shiny Zamazenta in their Pokémon Sword game and Shiny Zacian in their Pokémon Shield game. Codes are available from GAME stores in the UK and GameStop stores in Ireland between 22 October and 18 November. These codes can be obtained at no cost, while supplies last (no purchase necessary).
Zacian and Zamazenta were introduced as Legendary Pokémon when the Pokémon Sword and Pokémon Shield games were first released. In its Crowned Sword form, Zacian is a Fairy- and Steel-type Pokémon that holds a sword in its mouth and attacks with grace, and Zamazenta—when it’s in Crowned Shield form—is a Fighting- and Steel-type Pokémon that has a shield-covered body and regal movements.
Pokémon Sword and Pokémon Shield are core Pokémon video game titles and are both available on Nintendo Switch systems.
