The game is set on a spaceship where the players are divided into two groups: crew members and impostors. The goal of the crew members is to complete various tasks aboard the spaceship, while the impostors try to kill them off and sabotage their efforts.
The game consists of rounds that last about 10-20 minutes, depending on the number of players. At the beginning of each round, players are randomly assigned their roles and the game begins. The crew members have to work together to complete tasks around the spaceship, while the impostors try to blend in and kill off the crew members one by one. The catch is that impostors are among the crew members, and they have to deceive others to succeed.
