Limbo launched as part of Microsoft's 2010 Summer of Arcade promotion. After a successful critical reception on the Xbox 360, the game saw release on the PlayStation 3 and PC, and it has now crossed a significant sales milestone.
Playdead announced that its silhouette-heavy side-scroller has crossed the 1 million units sold mark across platforms. Accompanying this milestone comes word that a Mac version of the game is set to land before the end of the year. As part of its announcement, Playdead also said that Limbo's success has allowed the studio to become fully independent by buying out early investors in the company.
Limbo puts players in the shoes of a small child who must find his way through a black-and-white world filled with puzzles and dangerous, often deadly obstacles. The game won critical acclaim upon release, which was followed by a small avalanche of award nominations that yielded multiple Interactive Achievement Awards and a Game Developers Choice Award.
