Yesterday at A-Kon, Aniplex of America announced that their smartphone title Fate/Grand Order will finally be released on June 25th in the U.S. and Canada for iOS and Android devices. The company ran a teaser trailer for the game during their panel, showing off new the new character class Lancer, which will be joining the Saber, Rider, Assassin, and Caster classes.
Delightworks is developing the North American version of Fate/Grand Order with a proper English version, but sadly, if you're already playing the Japanese version, you won't be able to convert any of your old data. If you start a new game with the English version, you'll need to start fresh.
The game has been downloaded over nine million times since the initial release back in 2015, spawning a Japanese TV special on New Years Eve called Fate/Grand Order: First Order, which brought in impressive numbers on CrunchyRoll the same day.
You can currently play the game in China, Macau, Taiwan, and Hong Kong, with Aniplex looking to branch out even further if the game is a success overseas. But it's probably going to take some time before you see a European version, as they'll want to see if the success translates over to the States first.
