World of Final Fantasy PS4 Players will lead a pair of twins through varied FINAL FANTASY worlds and encounter the adorably familiar monsters therein. Capture and raise such familiar beasts as cactuar chocobo and behemoth to discover alternate forms and learn new abilities.One of the key features of the game is a “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 the most challenging opponents.
