Key takeaways

  • Among Us belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Among Us to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Among Us from memory before moving on to harder problems.

Reference excerpt

Among Us is a 2018 online multiplayer social deduction game developed and published by the American game studio Innersloth. The game allows for cross-platform play; it was released on iOS and Android devices in June 2018 and on Windows later that year in November. It was ported to the Nintendo Switch in December 2020 and on the PlayStation 4, PlayStation 5, Xbox One and Xbox Series X/S in December 2021. Among Us takes place in space-themed settings where players are colorful, armless cartoon astronauts. Each player takes on one of two roles: most are Crewmates, but a small number are Impostors. Crewmates work to complete assigned tasks in the game while identifying and voting out suspected Impostors (who appear identical to Crewmates) using social deduction, while Impostors have the objective of killing the Crewmates. The game was inspired by the party game Mafia and the science fiction horror film The Thing. While the game was initially released in 2018 to little mainstream attention, it received a massive rise in popularity in 2020 due to many Twitch streamers and YouTubers playing it during the COVID-19 pandemic. It received favorable reviews from critics for fun and entertaining gameplay. The game and its stylized characters have been the subject of various internet memes. Following the game's success in 2020, the game has received multiple updates and spawned a multimedia franchise, with Among Us 3D launching in 2022, a TV series launching all-at-once in 2026, and a spinoff game, Among Us Story: On Guard, in development as of June 2026.

Gameplay

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. Impostors may 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 door log 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 can initiate a group meeting either by reporting a dead body or by pressing the Emergency Meeting button. During meetings, players discuss—via the in-game text chat or an external voice chat application such as Discord—who they believe to be Impostors based on available witness testimonies, with Impostors lying to hide their identity or falsely accusing other players. Impostors can be identified beyond reasonable doubt if they are seen killing a Crewmate unless there are Shapeshifters, or seen venting unless there are Engineers or Shapeshifters, but ultimately players must weigh the veracity or value of each other's statements. Players then vote for who they believe is an Impostor; if a plurality vote is obtained, the player who received the most votes is "ejected" from the game. Players who are killed or ejected become ghosts, which can still perform tasks (Crewmates) or sabotages (Impostors) but are otherwise unable to be seen by or interact with living players. Effectively, spectators and ghosts may see and pass through walls, follow players or other ghosts, and chat with other ghosts. A November 2021 update added additional specialized roles to the game: Crewmates can also be Engineers, Scientists, as well as regular Crewmates. The first Crewmate that dies can also become a Guardian Angel, the role of which is not given at the beginning of a round. Engineers can traverse vents like Impostors, albeit to a limited capacity. On the other hand, Impostors can stay in the vent as long as they want. Scientists can check vitals from anywhere on the map to see if any player has been killed this round. The ghost of the first Crewmate that dies can become the Guardian Angel, which can temporarily protect living players from being killed. Impostors likewise can be Shapeshifters, allowing them to temporarily morph into other players and assume their color and appearance. However, they might leave evidence behind depending on the game settings. An additional update in June 2024 added three more roles, including Noisemakers and Trackers to the roles of Crewmates, and Phantoms to those of Impostors. Noisemakers trigger an alert when they are killed that can visually indicate their death's location to other Crewmates. Trackers can track the location of another player for a limited amount of time. Phantoms are able to briefly turn invisible to avoid detection. In September 2025, two more roles were added: the Detective for Crewmates and the Viper for Impostors. Detectives are able to open case files for every murder and use their interrogation ability to find out where players were when a player was killed. Vipers are able to dissolve bodies over time, leaving no evidence. In August 2026, a new role was added: the Judge for crewmates. Judges are able to overrule votes in meetings and decide who gets ejected.

Worked examples

Example 1 — a first encounter with Among Us

Start with the simplest possible case. Write down what Among Us claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Among Us before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Among Us ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Among Us

In research
Among Us appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Among Us in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Among Us is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 video games, 2020 in Internet culture, Among Us, so understanding it makes those chapters shorter.
In everyday life
Look for Among Us outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
