It looks like a Tech Demo for a FF game codnamed 'Fortress' set in the world of Final Fantasy XII has been leaked.

As this 'demo' is still pretty basic it is unknown what console this game was or is still being developed for. Square-Enix had outsourced studo GRIN to work on this project but since they have gone under it remains unclear whether they will proceed with this game, perhaps using one of the Edios studios instead, or whether it will be lost along with the studio.
Interesting anyway
