The Perfect Organism

One of the biggest AI-driven titles of modern times, Alien: Isolation brings the terror of the xenomorph to video games. While the alien, LV-426 and many other key elements of the franchise have previously been explored, Alien: Isolation takes a different route. A horror game steeped in the aesthetic and style of Ridley Scott's classic 1979 movie: in which the player is trapped on the Sevastopol space station with a single, intelligent, near-invincible alien. For this experience to play out as expected, the alien itself has to carry a large amount of the experience: a demanding feat for any AI in an industry in which non-player characters are either heavily scripted or suffer really short life spans. So how did developers Creative Assembly pull it off?
