Limbo

Limbo (stylized as LIMBO) is a puzzle-platform game played by Markiplier.

Plot
The primary character in Limbo is a nameless boy, who awakens in the middle of a forest on the "edge of hell". While seeking his missing elder sister, he encounters only a few human characters who either attack him, run away, or are dead. At one point during his journey, he encounters a female character, who abruptly vanishes before he can reach her. The forest eventually gives way to a crumbling city environment. On completion of the final puzzle, the boy is thrown through a pane of glass and back into the forest. He walks a short distance until he again encounters a girl, who, upon his approach, stands up, startled. At this point, the game abruptly ends.

Gameplay
The game's set in a two-dimensional world where the player controls the boy who can run left or right, jump, climb onto short ledges or up and down ladders and ropes, and interact with objects which will be required for the second half of the game where the player needs to solve mechanical puzzles and avoid traps in order to progress. Limbo is presented through dark, greyscale graphics and with minimalist ambient sounds, creating an eerie, haunting environment. The dark visuals also hide numerous environmental and physical hazards, as well as lethal monsters.
