During Bandai Namco's mobile game panel at Anime Expo 2017, they announced Tales of the Rays will be released for iOS and Android devices sometime this summer as a free-to-play game. They're billing it as a "console-quality" game for mobile platforms.
Here's an overview of the details care of Bandai Namco:
In Tales of the Rays, players travel across diverse landscapes with heroes Ix and Mileena, exploring dungeons full of treasures and battling monstrous enemies in an epic quest to revive their world. Past Tales heroes will make appearances in the game with memories from their original worlds as experienced adventurers to provide Ix and Mileena with guidance as they embark on their journey.
Tales of the Rays features console-quality graphics and gameplay, including the all-new Linear Motion Battles system, with simple controls optimised for mobile devices. Fans can look forward to stories told through animated cut-scenes with the classic soundtrack and music, as well as limited time events with special bonuses.
“We created Tales of The Rays with the intent to make it the best all-star character game ever. The story, music, and game design are handled by the very same team who brought you the Tales series on console, and the character design, voice acting, and opening animation are masterfully crafted by the hottest artists in Japan today. We're all very happy to be able to share the amazing storytelling and 3D gameplay with you, and our hope is that you're looking forward to the game's release as much as we are.” said Yasuhiro Ikeno, Producer of Tales of The Rays at BANDAI NAMCO Entertainment Inc.
Some details were also shared from the panel itself. Much like Fate/Grand Order, your account is tied to the region you have registered it in. Meaning, you will not be able to transfer your character data from the Japanese to the Global servers.
It also doesn't feature a multiplayer component at the moment, and it appears the content of our version may always be 6 months behind the Japanese release due to the speed at which they update the game.
The good news is, you will be able to unlock every character in the game without having to spend any money, of which there are 24 currently available in the Japanese release.
