Pokémon Unite, Tencent's free-to-play Pokémon MOBA, arrives for Nintendo Switch next week on 21st July.
Download the game and log in anytime before 31st August and you also gain access to the Mythical Pokémon Zeraora.
As previously announced, Pokémon Unite's mobile version then launches at some point in September (and there will be a way for mobile players to get Zeraora then as well).
