Square Enix has just announced a new Final Fantasy spin-off on mobile. Originally a 3DS title, Final Fantasy Explorers will be remade and released as Final Fantasy Explorers Force(ファイナルファンタジー エクスプローラーズ フォース)on iOS and Android in 2017.
Despite being a remake, Explorers Force is more like a complete new game with improved graphics. Not only can players breed the characters available, they can also turn them into characters from the previous Final Fantasy titles. The game supports at most five-player cooperation.
