GRIN had many undisclosed projects in the works before they closed down under the threat of bankruptcy. One of them was Project Fortress, the Ivalice Alliance game for Square Enix. Another was "Blue Steel," which many believe to be a Mega Man game for Capcom.
A third unnamed project has now been uncovered, thanks to an artist resumé. Pre-production material for this one, unlike the other two, details a complex battle system, featuring a ninja character with a sword and shield as seen above.
