The developer of Game of War Machine Zone, and Square Enix announced that an all new MMO mobile game for Square Enix's next Iteration in the Final Fantasy series Final Fantasy XV was in development.
Unfortunately there is no info as to what the game is called, or when it will be released. However, the characters, story and music from Final Fantasy XV will all be featured in the game, which uses Machine Zone's technology to unite millions of players around the world in real time, all within a single, shared universe.
I'm not familiar with Machine Zone, but it will be interesting to see how they'll bring this to mobile. I am curious as to whether or not they'll use something similar to their previous MMO title Final Fantasy XIV: A Realm Reborn. Hopefully we will receive more details soon.
Final Fantasy XV will be available on November 29, 2016 for Playstation 4, and Xbox One.
