Niantic announced on Thursday that it has added Legendary Pokémon Raikou, Entei, and Suicune to its Pokémon GO smartphone game.
Niantic also announced that it will hold field testing for its Exclusive Raid Battle feature, now titled EX Raid Battle.
Mewtwo will be the first Pokémon available through EX Raid Battles, but Niantic said that “other powerful Pokémon may also start to hatch from the Raid Eggs found at EX Raid Battles.”
The Pokémon can be caught in Raid Battles at Gyms, and will be available in different locations around the world in coming months.
