Here is an overview of the game, via Arc System Works:
Created in collaboration with developer French-Bread, Under Night In-Birth II Sys:Celes brings the final chapter in the “Hollow Night” storyline that began with the first series release over a decade ago. As an original addition to the fight game genre, the game brings novel-styled action, powerful duels with foes, fantastic visual environments, 21 returning characters, new In-Births joining the roster, compelling background music, and for the first time in the series, rollback netcode has been implemented.
Players take the protagonist role of high school youth Hyde as he encounters the mysterious girl, Linne, prompting his inner EXS powers to awaken. As the two band together, they struggle to defeat the fearsome Paradox. This leads to the appearance of the enigmatic Kuon the Aeon, who crushes the two victors and proclaims his advent of the world’s end. Linne disappears and Hyde, now determined to save their world from Kuon, ventures alone into the Night…
Under Night In-Birth II Sys:Celes is due out for PlayStation 5, PlayStation 4, Switch, and PC via Steam on January 25, 2024 worldwide. An open beta test will run across PlayStation 5 and PlayStation 4 from today until November 19.
