Japanese developer Compile Heart, the studio behind the Record of Agarest War and Hyperdimension Neptunia series, will bring Mugen Souls Z to the Japanese PlayStation 3 in spring 2013, the company announced.
Mugen Souls Z is the sequel to Mugen Souls, a PS3 role-playing game with turn-based combat released in March 2012 in Japan and in North America and Europe this past fall. Mugen Souls follows a group of children led by Chou-Chou, a young girl who seeks to conquer the universe by forging a union between seven parallel worlds.
According to the most recent issue of Dengenki PlayStation, Mugen Souls Z will introduce a new protagonist named Shirma who seeks to replace Chou-Chou as the "Undisputed God." Shirma will have to conquer 12 worlds rather than seven, and players can now team up with companions for more cooperative attacks. The magazine also mentioned a mechanic called "Chou-Chou Energy."
Currently the game is slated to release in Japan only. Polygon has reached out to Nippon Ichi Software America, publisher of Mugen Souls in North America, to ask if the company plans to release Mugen Souls Z internationally.
