Among Us is a 2018 online multiplayer social deduction game developed and published by American game studio Innersloth. Among Us takes place in space-themed (https://en.m.wikipedia.org/wiki/Science_fiction) settings where players are colorful armless cartoon astronauts. Each player takes on one of two roles: most are Crewmates, but a small number play Impostors. Crewmates work to complete assigned tasks in the game while identifying and voting out suspected Impostors (which appear identical to Crewma
tes) by means of social deduction, while Impostors have the objective of killing the Crewmates. 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 all Crewmates, 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 tasks to feign appearance as legitimate Crewmates, and are given a list of sample "fake" tasks to do so. Impostors, however, can perform sabotages, ranging from minor (such as disabling lights, making Crewmates blind) to critical (such as disabling oxygen generators, requiring immediate counteraction by Crewmates to prevent their deaths. Impostors may also enter and traverse ventilation ducts (commonly known as "venting"), and kill nearby Crewmates. To help Crewmates identify Impostors, there are various surveillance systems (on each map, such as security cameras on The Skeld, a doorlog system with sensors in MIRA HQ,
and a vitals indicator in Polus that shows the living status of all players. In addition, certain "visual tasks" provide animated cues, such as scanning oneself in the Skeld's medbay. As Impostors cannot perform tasks, Crewmates can use visual tasks to confirm their identity to nearby Crewmates. Any living player may call a group meeting by reporting a dead body, or by pressing an Emergency Meeting button (except during critical sabotages, when Emergency Meetings cannot be called, but dead bodies can still be reported). During meetings, players discuss — via the in-game chat on who they believe to be Impostors based on available witness testimonies, with Impost
