Square-Enix has announced that Dissidia Duodecim Prologus Final Fantasy, the demo for the upcoming Dissidia Duodecim, will be coming to the North American PlayStation Network on March 15. This demo tells a prologue story to Dissidia Duodecim featuring Lightning from Final Fantasy XIII. People who play this demo will get to carry over certain items into the main game, and will unlock Aerith from Final Fantasy VII as an assist character. Unfortunately, this demo is not free, and will cost $2.99 to download.

In addition to the news about Dissidia Duodecim Prologus, we also have several more screenshots for the game, which can be found here.
