Limbo is a puzzle platformer in which players control a boy as he traverses side-scrolling landscapes, solves obstacle puzzles, and defeats occasional enemies.

The game is rendered in black and white and the graphics are presented in a 2D side-view silhouette. Enemies throw fireballs, shoot arrows, or try to lure the boy into traps; traps and hazards contain giant boulders, saw blades, electric wires, spikes, and snapping bear traps. When killed, the boy gets flung around environments, impaled on spikes, or sliced into pieces. Black-and-white blood splashes accompany most attacks and death animations.

Playdead announced that its puzzle-platforming adventure, LIMBO, has now sold over one million copies worldwide – played by gamers in 153 countries in 9 languages across 3 platforms. This success has enabled Playdead to expand its independence by fully acquiring the company from early investors, laying the groundwork for the studio to begin developing and financing their next title.

"With the success that LIMBO has achieved, we felt this was the ideal time to fully regain our independence,” explained Dino Patti, Playdead CEO. “We are grateful to everyone who supported us over the past few years, and look forward to forging new partnerships that will both let us reach new heights as a studio and give our director, Arnt Jensen, room to grow creatively.”

Hot on the heels of this milestone, Playdead today also announced that a Mac version of LIMBO is in the works and will be released before the end of the year.
