Inside is a puzzle platformer in which the player character is an unnamed young red-shirted boy who explores a surreal environment presented as a primarily monochromatic 2.5D platform game, using color only to highlight parts of the environment. The game is very dark in nature and mostly silent, with only occasional musical cues. The player controls the boy who walks, runs, swims, climbs, and uses objects to overcome obstacles and progress in the game. Later the boy gains the ability to control bodies to complete certain puzzles, a mechanic that IGN's Marty Sliva compared to a similar mechanic in The Swapper. At various points in the game, the player may discover hidden rooms containing glowing orbs. If all the orbs are deactivated during a playthrough, the player can unlock the game's alternate ending.
The boy can die in various ways, such as being shot with a tranquilizer dart, mutilated by dogs, ensnared by security machines, blown apart by shockwaves, or drowning. As in the predecessor game Limbo, these deaths are presented realistically and are often graphic. If the character dies, the game continues from the most recent checkpoint.
