Beyond the city is a large factory of flooded rooms, a shock wave atrium, and a laboratory environment where scientists perform underwater experiments on bodies. The boy uses the farm animals and equipment to escape to a seemingly abandoned city where lines of zombie-like people are moved through mind control. He escapes the guards, then crosses a road where a block has been set up with more vehicles and guards, to a farm where parasitic worms cause pigs to run rampant. While running through a forest, he encounters masked guards with flashlights, as well as vehicles with mounted spotlights, and fierce guard dogs. If the character dies, the game continues from the most recent checkpoint. As in the predecessor game Limbo, these deaths are presented realistically and are often graphic, but to a larger degree, earning the ESRB's Mature rating as opposed to Limbo 's Teen rating. The boy can die in a multitude of ways, including drowning, being shot with a gun or tranquilizer dart, mauled by dogs, ensnared by security machines, being blown apart by shockwaves, and others. If all the orbs are deactivated during a playthrough, the player unlocks the game's alternate ending. At various points in the game, the player may discover hidden rooms containing glowing orbs. 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. The player controls the boy who walks, runs, swims, climbs, and uses objects to overcome obstacles and progress in the game. The game is mostly silent, with the exception of occasional musical cues, the boy's vocals, dogs barking, equipment and sound effects. The game is dark, with color used sparingly to highlight both the player and certain parts of the environment. The player character is an unnamed boy who explores a surreal and mostly monochromatic environment presented as a 2.5D platform game.

As with Limbo, Inside is included on multiple lists of the greatest video games of all time as compiled by game journalists. The game was nominated for numerous accolades, including game of the year, and won several independent and technical achievements. Critics noted it as an improvement over Limbo, praising its art direction, atmosphere and gameplay. Inside premiered at Microsoft's E3 2014 conference, with a planned release in 2015, but was delayed to 2016. The game was partially funded by a grant from the Danish Film Institute. The team switched to Unity to simplify development, adding their own rendering routines, later released as open source, to create a signature look. Playdead began work on Inside shortly after the release of Limbo, using Limbo 's custom game engine. It is the successor to Playdead's 2010 Limbo, with similar 2.5D gameplay. The player controls a boy in a dystopic world, solving environmental puzzles and avoiding death. A macOS version was released in June 2020. The game was released for iOS in December 2017 and Nintendo Switch in June 2018. Inside is a puzzle-platform game developed and published by Playdead in 2016, and was released on June 29, for Xbox One, Windows, on July 7, and August 23, for PlayStation 4.
