It appears the ‘unreleased masterpiece’ GRIN was working on before it closed its doors last week was a Final Fantasy game, based on a former employee’s LinkedIn profile page. Swedish 3D artist, Tomislav Spajic, says he worked on an “unannounced Final Fantasy project” on his LinkedIn page.
You can check out some of his work on his personal page, which includes images of a game named Fortress, which is likely the unreleased Final Fantasy game.
GRIN closed last week because of financial struggles.
