Dissidia Duodecim Prologus Final Fantasy is a promotional tie-in prequel for Dissidia 012 Final Fantasy.

This prologue features a single storyline with Lightning and the Warrior of Light as the main characters. It also contains an arcade mode with eight characters, one of whom must be unlocked.

The game features its own set of accomplishments, which give certain accessories as rewards, though there is no means of equipping them in either mode. However, all accessories gained can be carried over to Dissidia 012.
