Creative Assembly takes some time to talk about the creation and growth of the terrifying, stalking monster that will be lurking throughout Alien: Isolation.

This developer diary video features firsthand accounts about how the alien creature should be reacting to a stranger in its presence. Unlike the AI atrocities of Aliens: Colonial Marines, the alien in Isolation will not just sporadically spawn throughout the level and run straight at you. Instead, the alien is methodical, it hunts and it patiently stalks you until the time is right. It will try to blend into the shadows and if you alert it to your location (via making sound or being out in the open), it will try to creep up on you from the darkness.

No one will be able to hear you scream when Alien: Isolation hatches for Xbox 360, Xbox One, PlayStation 3, PlayStation 4 and PC near the end of the year.
