Astral Chain is a 2019 action-adventure hack and slash video game developed by PlatinumGames and published by Nintendo for Nintendo Switch. It was directed by Takahisa Taura, who was previously lead game designer for Nier: Automata, under supervision by Devil May Cry and Bayonetta series creator Hideki Kamiya, and character designs from manga artist Masakazu Katsura. Set in a dystopian future Earth, the game follows the events of a special police task force that protect remnants of humanity from interdimensional creatures and aberrations that invade the planet, with the story centering on the task force's two new twin recruits. Utilizing the titular "Astral Chain", the twins restrain and tether the creatures, employing them in combat and investigation, referring to them as "Legions". The setting of the game draws heavy inspiration from various cyberpunk manga and anime, while the gameplay combines hack and slash combat with role-playing elements and investigative adventure game sections. These segments revolve heavily around the simultaneous controlling of two characters; the player character twin and their Legion.
