The PlayStation 4 version of Fallen Legion, both versions have their own story and events following a different main character.

"Get ready to battle the beastly hordes in Fallen Legion: Sins of an Empire! Join Princess Cecille, a steely warrior guided by an enigmatic talking Grimoire, on a quest to save her crumbling kingdom.

Fallen Legion has an intense battle system where you control up to four characters simultaneously. One second your Exemplars are knocking a drake out of the sky and the next you’re commanding your team to block right before a magic spell hits to reflect it back at your foes. In between battles, you make split-second decisions that change how the game unfolds. Will you blackmail a prince for a speed buff? Or stand up to a warmongering governor instead of resurrecting a fallen party member? Each choice you make bestows a different power-up and permanently changes the world."

"A crumbling empire is in your hands, will you restore glory to Fenumia? Join Princess Cecille and a saucy, talking grimoire on her journey home as she fights hordes of monsters and a coup led by Legatus Laendur."
