Koei Tecmo and Akatsuki Games announced the release date of the latest Atelier game, Atelier Resleriana: Wasure Rareta Renkinjutsu to Goku Yoru no Kaihou-sha.
It'll be released in Japan on September 23 for IOS and Android. A PC release on Steam will also come, but it won't be at the same time as the mobile version.
For now, the release is only for the Japanese market, as a potential English localization has not been announced just yet.
Given the game's nature as mobile (for now) and free to play (with optional microtransactions), it remains to be seen whether Koei Tecmo will bring it westward at all.
Perhaps they may be waiting for the PC version, but that's just my personal speculation. To celebrate the announcement of the release date, we also got two character trailers focusing on Esca and Logy from Atelier Escha & Logy: Alchemists of the Dusk Sky.
... And below you can check out Logy in action.
Atelier Resleriana is basically an all-stars title, with characters from all Atelier games. This likely isn't too surprising as it fits the gacha model quite well.
The title translates as "Forgotten Alchemy and the Liberator of the Polar Night."
If you want to see more, you can check out the first gameplay revealed a few weeks ago, two trailers introducing the protagonists of the Gramnad series, Judie and Vio, and three more featuring the characters from Ryza's trilogy, Ryza, Lent, and Tao, on top of a bunch more from other series.
