Pokémon Ultra Sun Moon: Official Complete Guide

Pokémon Ultra Sun[a] and Pokémon Ultra Moon[b] are 2017 role-playing video games developed by Game Freak and published by The Pokémon Company and Nintendo for the Nintendo 3DS. Part of the seventh generation of the Pokémon video game series, the games are enhanced versions of Pokémon Sun and Pokémon Moon, which released the previous year. They are the final mainline Pokémon games for the Nintendo 3DS family of systems. Announced in June 2017, they were released worldwide on 17 November 2017.

As with previous installments, the games follow the journey of a young Pokémon trainer, taking place in the Alola region — based on Hawaii. Differences from Sun and Moon include an alternate storyline and new gameplay features, characters, Pokémon, and Pokémon forms, including new forms of the legendary Pokémon Necrozma as version mascots.

The games received generally positive reception, with critics praising the additional features included over Sun and Moon, although some criticized it for being too similar for a majority of the story. By the end of 2018, Ultra Sun and Ultra Moon had sold over eight million copies worldwide.
