Atelier Karia: The Night Kingdom & the Guide of Memories — unofficial guide

Atelier Karia is an upcoming single-player alchemy RPG from the Atelier series, listed by KOEI TECMO GAMES on Steam and on the official Atelier site. The official website, the PlayStation Store and the Xbox Store all give a release date of 25 February 2027 for PlayStation 5, Nintendo Switch 2, Xbox Series X|S and Steam.

KOEI TECMO’s Steam announcements also point readers to Gust’s official X account, and the game’s website sits on the long-running Atelier portal. This site treats Gust and KOEI TECMO as the official sources, and does not fill gaps with rumour.

What the official pages say the game is

The official story places Karia, an adventurer on the Aladiss Pioneering Team who has no memories of her past, two years after the alchemist Yumia uncovered the mysteries of the continent of Aladiss. A phenomenon called the mana withering begins to appear. While investigating ruins with the researcher Servio, Karia finds a vast world beneath Aladiss — later named Noctrem — a large cauldron, and alchemy itself.

The announced loop is to gather ingredients, synthesise items, use those items in exploration and battle, and eat ingredients or finished items to change Karia’s appearance and abilities. The official features pages also describe a new mana-piece synthesis board, real-time combat with a command menu, battles against colossal enemies, and bases you can build and furnish across the map.

How this guide is written

Every fact here is taken from the official website (including its English story, features and character pages), the Steam store and news posts, the PlayStation and Xbox storefronts, and the NIS America Premium Box page, all listed on the sources page. Wording is our own. Where those pages disagree — most clearly on the Steam date — both figures are given. Where they are silent, the page says so instead of guessing. Nothing here is from a play session; the game has not been released.
