Developed by Applibot and published by Square Enix, the free-to-play mobile game NieR Re[in]carnation features original music by Keiichi Okabe and Shotaro Seo of Monaca music studio.

Set in a series of towers and dungeons dubbed "the Cage," the mobile game was first announced in 2020 alongside the NieR Replicant remake. The scenario, written by Yoko Taro and Saito Yosuke, takes place at an unspecified period within the NieR timeline. Rooting the world-building in visual elements familiar to the franchise, art for the title was overseen by concept artist Kazuma Koda and character designer Akihiko Yoshida.

The 18-track soundtrack album ships on a single compact disc from the Square Enix store for North America and Europe, along with distributors CDJapan and Play-Asia. Excerpts of each track are streaming on the official album website.

From the product page:

A girl awakens on a cold stone floor. She finds herself in an infinitely vast place filled with buildings that touch the very sky. Guided by a mysterious creature who calls herself Mama, she begins to explore her new surroundings. To reclaim what she has lost —and atone for her sins—she sets off on a journey through this place of unknown creation.
