A scene of the Limbo world. Left: The Nameless Boy. Right: A deceased, hanging human.

The World (a.k.a LIMBO or Purgatory) is a state of existence between life and death. The ultimate goal of the game is for the boy to escape LIMBO and be at peace in death by locating his sister.

The world is filled with hazards, including traps, creatures (most notably The spider), and other, much more hostile humans. Other details of this monochromatic world are absent.
