Dissidia Duodecim [012] Prologus is a trademark that suddenly appeared. Many fans speculated that this might be a prologue to the events that will happen in Dissidia 012 while some speculate it as a paid demo of the game to get them hype with the finish product... and they are right. Yep, this game is a paid demo.
Square Enix formally announced it at their press event (which also confirms a FFXIII-2). It’s coming to PlayStation Network now and it exclusively adds Final Fantasy VII character Aerith/Aeris as an assist character! This demo will have an original short scenario and an arcade mode. You can get it for 300 yen or about $3.75. Take note, you must buy the game for you to play Aerith!
Special thanks to Siliconera!
