Imposter

The crew of a spacecraft is attempting to survive while it travels into infinite space. They must remain vigilant because one of them is a fake. When left alone with someone else, they should be on the lookout for vacant rooms and prepared for an attack—what if that someone is an impostor? The Impostor will stop at nothing to achieve his goal of killing everyone, even if it means destroying the ship. He is sly and crafty. He has the ability to wait for his prey in shadowy areas or to leap out of a ventilation shaft and launch a surprise attack from behind. He is not easily recognised among the team, unless he makes a mistake. Impostor, you wouldn't do that would you?
