宇宙船は無限の空間を旅している, そしてその乗組員は生き残ろうとしている. 彼らの間に詐欺師がいて、彼らは警戒する必要があります. They need to be aware of empty rooms, and be ready for an attack when left alone with someone else, what if that someone is the impostor. The Impostor wants to kill everyone and will stop at nothing, even if it means sabotaging the ship. He is cunning and sneaky. He can hide in dark corners and wait for his victim, or suddenly jump out of a ventilation shaft and attack from behind. It is difficult to identify him among the crew members, unless he makes a mistake. You wouldn't do that, would you, 詐欺師?
