A spaceship travels through the endless and boundless expanse of space, while the crew on board fear for their safety and try to save their lives. Among them is an impostor, an intruder who wants to harm the crew: the crew members know this, but there is nothing they can do about it. For this reason, they must be careful.
Danger at every turn
Members of the crew should be wary even of empty rooms, and be ready for an attack at any moment. Particular care should be taken when alone with someone else on the team in case that person is plotting something bad.
The intruder wants to kill all members of the crew, and is willing to go to any lengths. He can hide in the darkness and wait for his victim, or he can attack from the back. It is difficult to identify him among the crew members.
