It's kinda like Werewolf, Mafia, or Town of Salem. There are two roles, the vast majority of the players are "crewmates" who need to do various minigames around the ship, if the crewmates do them all then they win. The other role is the "Imposter" which usually only has one or two per game. Their job is to murder crewmates while going undetected, Imposters know who all the Imposters are but Crewmates don't know what role anyone is.They can sabotage various parts of the ship like turning out the lights to make sneaking around easier or messing with the Oxygen/Reactor to lure crewmates to an easy spot to kill them. If a Crewmate finds a deadbody they can report it which instantly pauses the game and goes to a discussion phase where everyone shares information and trys to figure out who the imposter is, ifthey figure it out correctly they can vote them out and throw them out the airlock, an Imposter needs to lie their way out of suspicion and manipulate the Crewmates into voting out one of their own instead. Crewmates win if they finish all tasks or vote out all Imposters, Imposters win by killing enough Crewmates until the living Crewmates are equal in number to the Imposters, Imposters also win if reactor/Oxygen sabotage isn't fixed after a certain amount of time. >>WHO are they among? There are two Imposters among us.
