Among Us

Among Us is a multiplayer game for four to fifteen players. Up to three players, based on the number of players and the game host's choice, are randomly and secretly chosen to be the Impostors each round. As of 2026, five playable maps are available: a spaceship called "The Skeld", an office building called "MIRA HQ", a planet base called "Polus", "The Airship", a setting from Innersloth's Henry Stickmin series, and the Fungle, a mushroom jungle map. The Crewmates can win the game one of two ways: either by completing all assigned tasks or by ejecting all Impostors.

Impostors can likewise win in two ways: either by killing or ejecting enough Crewmates, so that the number of Crewmates matches the number of Imposters, or by sabotaging a critical system on the map (provided the Crewmates do not resolve it in time). At the start of the game, Crewmates are assigned "tasks" to complete around the map in the form of minigames, minipuzzles, and simple toggles, mostly consisting of maintenance work on vital systems such as fixing wires and downloading data. Impostors cannot complete tasks but may pretend to perform them to feign appearance as legitimate Crewmates. Impostors, however, can perform sabotages, ranging from minor (such as disabling lights, limiting the Crewmates' vision) to critical (such as disabling oxygen generators), requiring immediate counteraction by Crewmates to prevent their deaths.

Among Us was inspired by the live party game Mafia, and the science fiction horror film The Thing. The idea for the concept was originally given by Marcus Bromander, co-founder of Innersloth, who had played Mafia since he was a kid. In the original game, function cards were dealt and players wandered around a house, aimlessly, while another person secretly killed the players, drawing a finger around their neck. Most of its mechanics were still present in Among Us, but the team wanted to "alleviate the need to create an interesting home model and have someone wandering around in a boring environment". So, they decided that the game would be space-themed and also added tasks, which, according to Forest Willard, programmer at Innersloth, "changed several times during development".

Development began in November 2017. The game was initially intended to be a mobile-only local multiplayer game with a single map. Bromander paused development on Innersloth's other game, The Henry Stickmin Collection, in order to build Among Us's first map, The Skeld. When they began developing the first map, they intended that the ship was always in crisis and that the Impostors could do tasks.

Among Us was well received by critics. On the aggregator website Metacritic, the PC port received a 85 of 100 score based on 9 critic reviews, while the Nintendo Switch version received a 79 of 100 score based on 9 critic reviews, both them indicating "generally favorable reviews". It was also considered one of the "Best PC Games for 2018", being ranked 17th, and as the "#38 Best Discussed PC Game of 2018". Since December 2020, IGN considered it one of 2020's best reviewed games so far.

Elliott Osange of Bonus Stage considered that the game is "silly fun", but felt that it is more fun "to be an Impostor". Craig Pearson of Rock, Paper, Shotgun had the same opinion, found playing as an Impostor "a lot more fun" than playing as a Crewmate, which he called "exhausting". In reference to the game's popularity among streamers, Evelyn Lau of The National said: "Watching the reactions of people trying to guess who the imposter is (and sometimes getting it very wrong) or lying terribly about not being the imposter is all quite entertaining." Alice O'Conner of Rock, Paper, Shotgun described the game as "Mafia or Werewolf but with minigames".

Among Us has done collaborations and cross-overs with other games and studios. The first game they collaborated with was Fall Guys, who added Among Us-themed skins to their game. Characters from Among Us have made cameos in the indie games Astroneer, Space Warlord Organ Trading Simulator, Cosmonious High, Samurai Gunn 2, and Fraymakers, and Among Us is referenced in several stickers in the game A Hat in Time. In a major update in collaboration with Innersloth, indie developer Triband added characters and 35 Among Us-themed levels to the game What the Golf?

Several Among Us-themed cards are included in The Binding of Isaac: Four Souls Requiem. Among Us also appears a skin for the Hearts suit in Balatro, using Crewmates in lieu of the King, Queen, and Jack. The Crewmate was added as a playable DLC character in Super Monkey Ball Banana Rumble in January 2025. Triband also developed a similar collaboration for What the Car?
