Six Pokemon Go Legendaries Are Back Again For December's Field Research

December is here, which means Niantic has rolled out a new batch of Field Research tasks for Pokemon Go. As usual, if you complete enough of these before the month ends, you'll earn an encounter with a rare Pokemon. This time around, however, the developer is giving players another chance to catch not one, but six previously featured Legendaries.

Each time you achieve a Research Breakthrough in December, you'll earn another chance to capture one of six Legendaries: Articuno, Zapdos, Moltres, Raikou, Entei, or Suicune. Each of these Pokemon was featured alongside previous Field Research tasks this year, making this a good opportunity to catch any of the ones you missed the first time around (or simply add more Legendaries to your collection).

The Legendaries aren't the only things returning to Pokemon Go in December. Niantic says it is also bringing back "some of the most popular Field Research tasks from past months." As before, you'll be able to acquire these by spinning the Photo Disc at different Poke Stops. In order to achieve a Research Breakthrough, you'll need to complete at least one Field Research task a day for seven days.

The new Field Research tasks rolled out on December 1 at 1 PM PT / 4 PM ET. Players had until then to complete November's slate of tasks and earn an encounter with Shedinja, the Bug/Ghost Pokemon first introduced in Ruby and Sapphire.

Pokemon Go's latest Community Day celebration took place on Friday, November 30. This time, the event ran through the entire weekend and brought back every featured Pokemon and special move from previous Community Days. Another Gen 4 Legendary, Cresselia, is also now available in Raid Battles and will remain there until December 18.
