There has been an outbreak of radiation sickness at the Icarus Space Station. You have been sent to investigate it but when you arrive you find that radiation sickness is not the station's only problem. The captain of the Icarus Space Station has been murdered and a power struggle for command of the ship has occured. Now the station is on a trajectory with the sun that no one knows how to fix.
Through interaction with more than 60 characters and exploration of 200 real-time rendered locations you need to try and save the station, and yourself. The game automatically randomizes sub-plots so that it will be different every time you play. Sentient requires six memory blocks for one saved game.
