"Urgent. This is orbital station PEGASUS. Presence of unidentified criminal on board. Demand immediate intervention. Situation of crew intolerable. I repeat, demand immediate intervention." Use observational, analytical, and interrogative abilities to track down a murderer on a space station before they claim their next victim. Save the lives of crew members by staying one step ahead of the killer – or witness their demise if you fall behind. Timing is key: 24 hours remain to solve the mystery, with crew members changing their positions and activities every hour of in-game time. Set the pace with the ability to speed up, slow down, and stop time. Ask the right questions: Interrogate crew members to get at their individual secrets and true intentions. Run biological tests and use specialized gadgets for clue detection and analysis. Dock a space shuttle, conduct a space walk, and explore a fully crewed space station in zero gravity – as imagined by the game's designers 8 years before the launch of the International Space Station.
