Hayama spent four years at SCE as its vice president, and will now take up a role at Bossa as creative director on its upcoming projects.

Bossa launched its first title, Monstermind, on Facebook earlier this year. A week prior to the release, the company was acquired by Shine Group, the British media company wholly owned by American media conglomerate News Corporation.

Regarding his move to Bossa, Hayama explained in a Eurogamer report, "The future of gaming is definitely online and thanks to recent developments with Flash 11, there is no reason why a social game can no longer be as visually stunning and as compelling as the big console titles," reports Eurogamer.

He continued, "Together at Bossa we have plans to bring a plethora of games to Facebook and eventually other appropriate social media channels, which include 3D elements and can be enjoyed by all age and interest groups."

Development on The Last Guardian has seen a troubling year. The game was delayed in April, while last month it was rumored that Ico creator Fumito Ueda had left Sony.
