The Pokémon Legends: Arceus game honors past Pokémon games’ core gameplay while infusing new action and RPG elements. You’ll need to catch, survey, and research wild Pokémon in a long-gone era of the Sinnoh region to create and complete the region’s first Pokédex. The story starts with the main character getting sent back in time by Arceus to the Hisui region, the Sinnoh region of ancient times, with one task in hand—to seek out all Pokemon. From the same day onward, strange lightning from the rift starts striking the Noble Pokemon, causing them to enter a frenzied state.
