Square Enix has given us some details of the downloadable episode called Sazh: Heads or Tails for Final Fantasy XIII-2. As Final Fantasy is not a series known for DLC like this, it should be interesting to tsee how long and good these updates are. The basic story takes place in Xanadu when Sazh arrives searching for Dazh.
The release date given was Feb 28th. I have not yet seen any specific pricing information on this yet, but it will be interesting to see how this DLC is received.
