Developer YummyYummyTummy announced that it will be releasing Fallen Legion for PC via Steam on January 5, 2018. The PC version, titled Fallen Legion+, will include the content from both versions of the game: the original PlayStation 4 version Sins of an Empire and the original PlayStation Vita version Flames of Rebellion, the latter of which also releases for PlayStation 4 on December 12, 2017.

Fallen Legion is set in the Fenumian Empire after its ruler passes away, with the two versions telling different sides of the tale. Sins of an Empire follows Princess Cecille as she comes into possession of a talking and powerful grimoire and attempts to keep the empire intact, while Flames of Rebellion follows military leader Legatus Laendur as he attempts to overthrow the royal family.
