After Grin's first release Ballistics, Grin released the critically acclaimed ' and several arcade machines, as well as military and civilian simulators. Grin went on to develop two games for Ubisoft, Tom Clancy's Ghost Recon Advanced Warfighter and Tom Clancy'sGhost Recon Advanced Warfighter 2. Bionic Commando Rearmed, Bionic Commando, ' and Terminator Salvation were the last titles, released in 2008-2009. In 2007, Grin expanded into offices on the Barcelona, Spain beach front, in the Torre Mapfre skyscraper, followed by another studio in the center of Gothenburg, Sweden, along with the Grin Jakarta QA studio, located in the center of Jakarta, Indonesia. 250 people in total were developing games for the Xbox 360, PlayStation 3 and PC. Grin began preproduction work on a Final Fantasy spin-off game, Fortress, in the second half of 2008 when Square Enix outsourced it to the Swedish developer. The development team, based in Stockholm, began creating concept art, 3D models and a game engine, thinking of Fortress as a "game with an epic scale both in story and production values". In addition to original characters and locations, concept art for the game depicted Ashe and a Judge character from Final Fantasy XII, and chocobos and other recurring creatures of the series. The score was also being produced. However, after six months of development, Square Enix reclaimed the project without paying Grin, due to concerns over the quality of the work. Grin co-founders Ulf and Bo Andersson claimed that "Square Enix had already made up its mind that Fortress wasn't a project it wanted anymore". Square Enix's withdrawal left the Swedish developer in financial difficulty and with no other ongoing game project. In 2009, Grin closed its offices in Barcelona and Gothenburg, citing financial difficulties. On August 12, 2009 Grin filed for bankruptcy. Later the same day, the official Grin site published the news that the company was closing down. Grin noted that delayed payments from "too many publishers" caused "an unbearable cashflow situation" and mentioning in a farewell note their "unreleased masterpiece that weren't allowed to finish". Former members of Grin formed a new development studio, Might and Delight, which focuses on small, downloadable games. Together with the owners of Fatshark, the former lead engineers of Grin started middleware developer Bitsquid, which was later bought by Autodesk. Former quality assurance members formed a separate studio called Trinity QA Studio in June 2010. Bo and Ulf Andersson went on to form Overkill Software. Bertil Hörberg, who worked on both Bionic Commando and Bionic Commando Rearmed, went on to form Hörberg Productions, a one-man studio responsible for the well-received Gunman Clive and its sequel Gunman Clive 2. The games were bundled together as Gunman Clive HD Collection for Wii U and Nintendo Switch.
