Pokémon Legends: Arceus is an action role-playing game developed by Game Freak and published by Nintendo and The Pokémon Company for the Nintendo Switch. Released worldwide on January 28, 2022, it serves as a prequel to the core Pokémon series, taking players to the Hisui region—a bygone era that would eventually become the Sinnoh region of Pokémon Diamond and Pearl. The game introduces a new style of gameplay that blends traditional Pokémon catching and battling with open-area exploration, emphasizing observation and research to complete the region's first Pokédex.
The story follows a young protagonist who is transported through time to the Hisui region, where they join the Galaxy Expedition Team's Survey Corps. Tasked with studying Pokémon to create the region's first Pokédex, the player navigates a world where humans and Pokémon do not yet live in harmony. The game explores themes of coexistence, discovery, and the origins of the bond between people and Pokémon, all while unraveling the mystery surrounding the mythical Pokémon Arceus.
Pokémon Legends: Arceus was praised for its bold reinvention of the Pokémon formula, offering a more immersive and dynamic experience than previous entries. Its setting in an ancient, untamed version of a familiar region provided rich narrative opportunities, and the game's focus on research and crafting added depth to the classic catch-and-battle loop. The Hisui region's distinct aesthetic, inspired by feudal Japan, and its roster of regional variant Pokémon and new evolutions were widely celebrated by fans and critics alike.
