A Pokémon GO Special Weekend event is scheduled to take place later this year in Korea. It is similar to the one that was recently announced for Japan, featuring special spawns of certain letters of Unown, Farfetch’d and other rare Pokémon. The ticket exchange for the upcoming Korean event is scheduled to take place on July 29 from 10 a.m. to 8 p.m. local time. Korean sponsors include three major companies in Korea: 7-Eleven, Lotteria and SK telecom. To learn more about this particular event, refer to the below poster and click here.
