Description from the publisher: In Project Airlock, the crew of a starship must work together to survive the hazardous journey back to their home planet. However, one member of the crew is secretly a saboteur, plotting to destroy the ship. The other crew members must do their best to keep the ship intact and force the saboteur out of the airlock, but if they choose the wrong person, the consequences could be dire. In this intense game for 3-6 players, the crew must fend off hazards ranging from hull breaches to wormholes, and at the same time try to identify an unknown saboteur. Meanwhile, the saboteur must destroy the ship's oxygen supply while pitting the crew members' suspicions against one another.
