Alien: Isolation places an emphasis on stealth and survival horror gameplay, requiring the player to avoid and outsmart a single Alien creature with tools such as a motion tracker and flamethrower. It was designed to resemble the original film rather than its more action-oriented 1986 sequel Aliens, and features a similar lo-fi, 1970s vision of what the future would look like. The game runs on an engine built from scratch to accommodate technical aspects such as atmospheric and lighting effects and the Alien's behaviour. Creative Assembly intended to make Alien: Isolation a third-person game, but used first-person to create a more intense experience.
