Pokémon GO Wild Area: Global is underway Nov. 14-15, featuring the global debut of Gigantamax Duraludon in six-star Max Battles. Trainers worldwide are also more than halfway toward a 500,000 check-in goal that will unlock a code for 10 Max Mushrooms, which double Pokémon’s damage in Max Battles during the event. The event runs from 10 a.m. to 6 p.m. local time each day, with raids, rotating Steel- and Dragon-type wild encounters, mighty Pokémon and GO Safari Balls. Ticket holders can access exclusive Special Research and additional bonuses.
