A new illustration and details about the content of Season Pass were revealed!
Hertfordshire, 26th September 2025 – Today, KOEI TECMO Europe and developer Gust launched the latest title in the Atelier series, Atelier Resleriana: The Red Alchemist & the White Guardian, worldwide on PlayStation®5, Nintendo Switch™ and PC Windows via Steam®. To celebrate, a launch trailer and new illustration have been released, inviting all players to journey under the stars alongside new protagonists Rias and Slade.
Atelier Resleriana: The Red Alchemist & the White Guardian follows the journey of Rias Eidreise, an adventurer with a talent for alchemy, and Slade Clauslyter, a young man capable of opening entrances to dimensional paths leading to alternate dimensions. The two heroes join forces in an attempt to discover the reason for the disappearance of the inhabitants of Hallfein, while also trying to follow in the footsteps of their loved ones and restore their hometown. During their journey, they will meet familiar faces from the Atelier series who will join their team including Sophie Nuenmuller, Razeluxe Meitzen, Totori Helmold, and Wilbell Voll-Ersleid.
Set in the universe of Atelier Resleriana: Forgotten Alchemy and the Polar Night Liberator, this new Atelier title will transport players to the continent of Lantarna where they can explore, gather ingredients for synthesis, and discover every secret corner, day or night, rain or shine. Players will also have the opportunity to explore multi-level dungeons known as “Dimensional Paths” where the structure will change randomly with each visit, allowing players to gather different ingredients and challenge new enemies depending on the difficulty level chosen.
Fights in Atelier Resleriana: The Red Alchemist & the White Guardian blend strategy with turn-based combat for strategic timeline command battles where action points and equipped items can be used to inflict damage and influence the timeline of characters’ turns, triggering consecutive turns for allies, and activating powerful unite attacks. By using ingredients gathered during exploration or combat, Rias will be able to synthesise various items during a process called “Gift Colour Synthesis” in which players connect the “Gift Colours” of the ingredients together to create new items. In addition to the traditional gameplay loop Atelier fans know and love, players can sell items they have synthesised via Rias’ shop. By visiting the Town Hall, “Star Landing”, money earned can be invested by completing requests and selling items in the five districts composing Hallfein, which will help to rebuild the town.
In celebration of the release of Atelier Resleriana: The Red Alchemist & the White Guardian, the first paid DLC for the game, the Gust Extra BGM Pack, has been released. More details about the content of the Season Pass have also been shared, including content of the three DLCs; the “Beginning of Summer Days” costume set, which includes six costumes* for playable characters, is expected to release November 2025. Upcoming Season Pass DLCs will introduce new playable characters** to the game by end of December 2025, as well as a brand-new high-difficulty dungeon*** by end of January 2026. Please note that some of the content can be purchased outside of the Season Pass. Be careful not to make duplicate purchases.
Aside from the standard version of the game, the Digital Deluxe Edition is also available and includes the base game, a selection of costumes for all playable characters, and a pack of items. Players can also purchase the Ultimate Edition which includes the Season Pass, the Season Pass purchase bonus (a collaborative costume with Atelier Yumia: The Alchemist of Memories & the Envisioned Land for Rias and Slade), and the content from the Digital Deluxe Edition. Everyone who purchases either a physical or digital edition up to the first two weeks after release will receive the “Activewear Adventuring Set” for Rias and Slade, and the “Adventuring Charm Set” as early purchase bonus.
Atelier Resleriana: The Red Alchemist & the White Guardian is now available on PlayStation®5, Nintendo Switch™ and Windows PC via Steam®. The game can be played as entirely offline adventure with no internet connection required (an internet connection is required to apply updates and additional content). The PlayStation® 4 version is not sold outside of Japan.
