Among Us takes place in a space-themed setting where players look like colorful armless cartoon astronauts; however, since the release of "The Skeld" spaceship, three other maps have been added in later years: the skyscraper "MIRA HQ", the "Polus" planetary station, and "The Airship" (based on Infiltrating the Airship from the Henry Stickmin series, also developed by Innersloth). Each player takes on one of two roles—most are Crewmates, but a small number play Impostors—which does not alter their appearance.[d] The goal of the Crewmates is to either identify and vote out the Impostors, or to complete all the tasks around the map; the goal of the Impostors is to covertly sabotage the mission either by killing the Crewmates before they complete all their tasks or by triggering a disaster that is not resolved in time.
