Attention everyone! There is an imposter on the ship! Nobody knows who it is, but the trace of dead bodies convincingly suggests he isn’t going to stop. He will keep killing until there is no person left alive on board! The crew has to take care of their own survival by watching each other closely and figuring out who the murderer is. The task of the traitor, on the other hand, is to make sure they remain undiscovered and keep doing their bloody business quietly to win the game!
