Players will collect, raise and take into battle the monsters of Final Fantasy lore, making it sound like Monster Hunter but it will actually be a more traditional RPG. It will use the 'Active Time Battle' system which involves turn-by-turn combat used in older Final Fantasy – making it sound like Pokémon to us. Monsters will include Cactuar, Chocobo, and Behemoth.

"One of the key features of the game is the 'stacking' ability, the siblings can adjust their size, turning small enough to jump onto the monsters during combat, or vice versa, shrink the monsters small enough to ride on the twins. By customizing and stacking their army of monsters, players can create strategic tower combinations and take on challenging opponents," said Square Enix.
