The game will use Switch's more unique features to allow for local ad-hoc multiplayer, as well as single-JoyCon play.
The update will feature 5 new Pokemon - Darkrai, Scizor, Empoleon, Croagunk and Pokemon Sun and Moon's owl archer, Decidueye.
The new version also introduces 3v3 team battles, online ranked play, and friend-only group matches.
