Niantic and The Pokémon Company International just announced a new in game event for Pokémon GO.
Pokémon GO Adventure Week begins this Friday at 9 PM and will go on until 9 PM on May 25. There will be increased encounter rates for Rock-Type Pokémon including the elusive ones like Onix. Each Pokestop will have more items available for trainers. Candy will be found in a fourth of the distance travelled. There will be a new avatar wardrobe item that will be given to all Trainers for free called the Adventurer’s Hat. More information about the event is available here.
Pokémon GO is available on iOS and Android devices.
