Before GRIN went bust, the Swedish developer was working on a new action-RPG related to Final Fantasy. Known internally as Fortress, footage and further info about the title has leaked, along with the suggestion that it is still in development at one of Square Enix’s other studios.

FORTRESS is the codename of an official, but currently unannounced sequel to FINAL FANTASY XII.
It is an action game set some time after the events of FINAL FANTASY XII: REVENANT WINGS, and is intended for the PlayStation 3, Xbox 360 and Windows platforms.

The project was originally developed by GRIN and supervised by Square Enix, but issues between the two companies led to GRIN going bankrupt and Square Enix reclaiming the project from them.

The project has not been officially announced yet, but its existence is known due to information leaked by former members of the development team and sources in the video game industry.

The Fortress project is still supported by Square Enix and in development at a currently undisclosed studio — possibly Eidos Montreal, Square Enix’s main Western branch.
