Sentient

Sentient is a first-person adventure game developed and published by Psygnosis, originally released in 1997 for the PlayStation and PC. Set aboard the space station Icarus, players are sent to investigate a radiation sickness outbreak, only to discover a murdered captain, a threatened senior Senator, and a station hurtling toward the sun. The game utilizes a sophisticated artificial intelligence system to control multiple crew members, each with their own assignments, behaviors, and opinions. Players interact through an elaborate parser interface and navigate through 200 real-time rendered locations. With automatically randomized sub-plots, the game offers a different experience every playthrough as you try to save the ship and yourself.
