Niantic has announced that all 24 challenges in the Global Challenge Arena during Pokémon GO Fest 2021 were completed and the details for the Ultra Unlock Part 1: Time and Ultra Unlock Part 2: Space have been revealed.

Prepare for Ultra Unlock Part 1: Time and Ultra Unlock Part 2: Space!

Trainers, Incredible work completing all 24 challenges in the Global Challenge Arena during Pokémon GO Fest 2021! As is tradition with Pokémon GO Fest events, we’re excited to unveil more details on this year’s Ultra Unlock bonus events.

As you know, the Mythical Pokémon Hoopa appeared during Pokémon GO Fest 2021 just the other day. Hoopa seemed intent on causing mischief and summoned all kinds of Legendary Pokémon to raids! That mischief is continuing even now, and it seems the Legendary Pokémon Dialga and Palkia will be summoned to raids next! Keep an eye on how time and space are distorted by the appearance of each of these Legendary Pokémon. There’s still no sign of Hoopa reappearing, but we’ll continue to monitor the situation. For now, read on to learn about what awaits you in Parts 1 and 2 of this year’s Ultra Unlock!
