Inside (stylized as INSIDE) is a puzzle-platformer adventure game developed and published by Playdead in 2016 for PlayStation 4, Xbox One and Microsoft Windows. The game was released for iOS in December 2017. The player controls a boy in a dystopic world, solving environmental puzzles and avoiding death. It is the spiritual successor to Playdead's 2010 game Limbo, and features similar 2.5D gameplay.
Playdead began work on Inside shortly after the release of Limbo, using Limbo's custom game engine. The team switched to Unity to simplify development, adding their own rendering routines, later released as open source, to create a signature look. The game was partially funded by a grant from the Danish Film Institute.
Inside premiered at Microsoft's E3 2014 conference, with a planned release in 2015. The game was released for Xbox One on June 29, 2016, Microsoft Windows on July 7, PlayStation 4 on August 23, for iOS and Apple TV on December 15, 2017 and for Nintendo Switch on June 28, 2018.
Gameplay
Inside is a puzzle platformer. The player character is an unnamed boy who explores a surreal and mostly monochromatic environment presented as a 2.5D platform game. The game is dark, with color used sparingly to highlight both the player and certain parts of the environment. The game is also mostly silent, with the exception of occasional musical cues. The player controls the boy who walks, runs, swims, climbs, and uses objects to overcome obstacles and progress in the game. 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 unlocks the game's alternate ending.
The boy can die in various ways, such as being shot with a tranquilizer dart, mauled 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.
Plot
A boy slides down a rocky incline. While running through a forest, he encounters masked guards with flashlights, as well as vehicles with mounted spotlights, and fierce guard dogs. 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. 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. 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.
While traversing these areas, the boy uses a mind-control helmet to control lifeless grey bodies. The boy eventually comes across an underwater siren-like creature that attaches a device to him, allowing him to breathe underwater.
Continuing through the office and laboratories, the boy sees scientists observing a large spherical chamber. The boy enters the chamber and discovers a large blob-like creature, the Huddle, made of humanoid limbs connected to four control rods. After disconnecting the rods, the boy is pulled into the Huddle.
The Huddle escapes confinement, crashing through offices, killing some of the scientists in its path. The scientists trap the Huddle in another tank, but the Huddle escapes again and breaks through a wooden wall. It rolls down a forest hill and comes to a stop at a grassy coastline bathed in light.
Alternate ending
If the player deactivated the hidden light orbs in the various bunkers, the boy returns to one of the bunkers and gains access to a new area. He reaches an area that includes a bank of computers and one of the mind-control helmets, powered by a nearby socket. The boy pulls the plug from the socket, upon which the character takes the same stance as the zombies, and the game ends moments later.
Theories
Journalists and players have offered several different theories about the game's main ending (the freeing of the Huddle) and the alternative ending.
One theory speculates that the boy is controlled by the Huddle throughout most of the game, leading him to help free the Huddle from containment. As described by Jeffrey Matulef of Eurogamer, the game impresses that the Huddle has a magnetic-like draw that leads the boy to endanger himself and unquestioningly enter the tank where the Huddle is kept so as to free it. Players speculated on the theory that taking the alternate ending is working contrary to the Huddle's goal, and the act of unplugging the computers is to release the Huddle's control on the boy. A similar theory has the boy being controlled by one or more of the scientists, evidenced by how some of the scientists appear to aid the Huddle in escaping the facility. In this theory, the scientists put the boy through many dangers to gain strength and intelligence, so that these qualities can be absorbed by the Huddle when the boy frees it, improving the creature in a desirable manner for these scientists.
A more metafiction interpretation of the game from its alternate ending, and considered the most popular among players, is based on the notion of player agency. Matulef summarizes this theory as "the boy is being controlled by a renegade force represented by the player". The act of pulling the plug in the final area is similar to the concept of The Matrix, as described by PC Gamer's Tim Clark. Matulef explains that the location of the alternate ending is only known to the player with knowledge of the main ending and not to the Huddle or the scientists. With knowledge of the game's true ending, achieving the alternate ending is to reach a conclusion to the game that "ostensibly puts an end to the boy, the blob, and any inhumane experiments being conducted".
Reception
Inside received universal acclaim, according to video game review aggregator Metacritic. Critics favorably compared the title as a worthy successor to Limbo. The game was one of Polygon and IGN's most anticipated 2016 releases. From previewing the game at E3 2016, IGN's Marty Sliva considered the title to be "Super Limbo", polishing and improving from Playdead's first game into the new title in the same manner that Nintendo had done for its previous games in bringing them to the Super Nintendo Entertainment System. Kirk Hamilton of Kotaku called the game an "evolution" on what Playdead has succeeded to do with Limbo. Jaz Rignall of USgamer previewed Inside and wrote that it was one of the best puzzle platformers he has played, even better than its predecessor.
