Just a few months back, Niantic added its first “Special Research” to Pokémon GO. Sort of like an in-game quest, the research had players complete a series of tasks (often over a number of days) to unlock an otherwise unobtainable Pokémon.
Now they’re back with another one.
The company will be adding a second Special Research quest to the game on August 20th. Whereas the last set unlocked Mew from the first generation of Pokémon games, this one brings out Gen II’s Celebi.
