The official Twitter account for the Mist Gears multimedia collaboration project by mobile gaming company Alim, tri-Ace, and Shueisha revealed on Thursday that the game will debut for iOS and Android devices on November 26.

The project's story begins with the "Day of Purgatory" marking the arrival of Mist, a calamitous mist that becomes the worst disaster in known history. Life crumbles with its arrival, and strange beasts emerge from it. Humanity seems to be on the path to extinction. 70 years after the Day of Purgatory, the Valks Kingdom begins "Mist Gear," a project that will restore hope to humanity.

The game is labeled an "environment RPG." Players explore a world hidden in Mist, with Mist affecting battles, and also powering up skills called Mist Cores. Up to four players can team up with their Mist Gears to explore, investigate, and fight together.

The franchise also has a manga by Yōichi Amano, and a novel.
