Skip to 1:08. This is only gonna be available in day 1 editions of FF Type-0. This makes no sense because there is some story aspects in the demo like meeting Cidny (Cid) so I really don't understand how this is supposed to work.
Edit: FYI they say what Episode Duscae is to FFXV is what Ground Zeros is to MGSV.
