Atelier Resleriana release date announced for Nintendo Switch, new trailer

Today, Koei Tecmo and Gust unveiled the release date for Atelier Resleriana: The Red Alchemist & the White Guardian. Nintendo Switch owners can play the RPG starting on September 26, 2025.

Atelier Resleriana was originally announced last September. Last we heard, it was on track to launch sometime this year – now we know when.

Here’s the latest information about the game:

Atelier Resleriana: The Red Alchemist & the White Guardian takes players on a new mysterious and cosy adventure alongside new characters 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. These two protagonists will 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 various characters who will help them, including familiar faces from the Atelier series such as 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 will blend strategy with turn-based combat for strategic timeline command battles where players can form a team of six characters (three in the front line and three in the back). By using action points and equipped items to their advantage, users will be able to inflict damage and influence the timeline of characters’ turns, triggering consecutive turns for allies and activating powerful unite attacks.

Using ingredients gathered during exploration or combat, Rias will be able to synthesise various items during a process called “Gift Colour Synthesis”. During this synthesis process, players will have to connect the “Gift Colours” of the ingredients together to create new items. They will also be able to assign traits or change recipes depending on the ingredients used. When certain characters come to lend Rias a hand, this will further strengthen the item created.

In addition to the traditional Atelier gameplay system alternating between exploration, combat and synthesis, users will be able to sell items via Rias’ shop while helping to develop the town. By selling synthesised items, players will earn money they can invest in the development of Hallfein, thus unlocking new recipes and progressing through the main story.
