Grin made Bionic Commando — Square Enix cancelled a Final Fantasy project without paying

Grin was founded in 1997 in Stockholm, Sweden, by brothers Bo and Ulf Andersson. The studio built a reputation for high-quality PC ports of console games, including Tom Clancy's Ghost Recon Advanced Warfighter and its sequel. It later developed original titles including Ballistics and Bandits: Phoenix Rising, and became best known for Bionic Commando Rearmed (2008), a critically acclaimed remake of the classic NES game. At its peak Grin had around 150 employees across offices in Stockholm, Barcelona, and Gothenburg.

In 2008, Square Enix outsourced development of a Final Fantasy spin-off codenamed Fortress to Grin. The project had been in development for approximately six months when Square Enix reclaimed it, citing quality concerns — and crucially, did not pay Grin for the work already completed. Left without a major project and with a large team to support, Grin began to unravel.

Compounding the loss, Grin's original Bionic Commando reboot (2009) and Terminator Salvation (2009) both underperformed commercially. Delayed payments from multiple publishers created what the studio described as 'an unbearable cashflow situation.' In early 2009, Grin closed its Barcelona and Gothenburg offices in an attempt to cut costs, but the financial hole was too deep.

On 12 August 2009, Grin filed for bankruptcy. The studio's farewell note referenced 'an unreleased masterpiece that we weren't allowed to finish' — the cancelled Final Fantasy project. Most of the 150 staff lost their jobs. The Andersson brothers went on to found Overkill Software, which later developed the Payday series.
