Pokemon Go has provided additional details about its Kalos Celebration event. The event, which starts on December 2nd, will help kick off the arrival of Kalos Pokemon to Pokemon Go, as well as launch the first event in Pokemon Go's "Season of Celebration," its first themed season. The event will feature over a dozen new Pokemon, along with special Field Research and Timed Research, in addition to increased spawns of certain Pokemon that first appeared in Pokemon X and Pokemon Y.

The Kalos Celebration Event is just one facet of Pokemon Go's major "Go Beyond" update, which has started its rollout this week. Pokemon Go also overhauled its Go Battle League, increased its Level Cap, and instituted numerous minor changes to other parts of the game.
