Pokemon Go Global Challenge Will Unlock Zapdos Day on July 21

This year, Pokemon Go Fest 2018 is returning to Chicago's Lincoln Park on July 14-15. Pokemon Go players will gather to play the game and complete challenges. If certain areas around the world reach their challenge requirements, it'll unlock bonuses. These bonuses will improve your ability to capture Pokemon, participate in Raid Battles, and even hatch eggs.

Assuming all challenge goals are achieved, Zapdos Day will unlock on July 21. On that day, Zapdos will be available for Raid Battles for a three-hour window! Players worldwide will potentially receive up to five free Raid passes when they spin a Photo Disc at a Gym on Zapdos Day.

All Zapdos caught during this period will know the Fast Attack Thundershock and players may even encounter a Shiny Zapdos if they're lucky.

This is the second such event in Pokemon Go, with the previous one offering the ability to unlock and capture Articuno. One can assume that another event will take place allowing players to fight and pick up Moltres. If you want to know more about Pokemon Go Fest Global Challenge, you can check out our handy guide.
