GRIN closed its doors last week, causing a flood of ex-staffers to put their work online in the hopes of scoring a job. Tomislav Spajic is one of those former employees and has confirmed on his LinkedIn profile that GRIN's "unreleased masterpiece" was actually a Final Fantasy game for Square Enix. Yeah, we can hardly believe it, too.
In fact, Spajic's personal site has a whole bunch of concept art and one of the games listed (called "Fortress") is likely the Final Fantasy game for Square Enix. We've seen it on other ex-GRINners' LinkedIn pages, like Erik Lindqvist's here, where Lindqvist flat-out says, "During 2009 I've been working on the preproduction for an unannounced, and now canceled project with the production name 'Fortress' for Square Enix."
