Alien: Isolation is a survival horror game developed by Creative Assembly and based on the Alien science fiction horror film series. It was published by Sega and released for Windows, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One in October 2014. The game is set 15 years after the events of the 1979 Alien film and follows Amanda Ripley, daughter of Alien protagonist Ellen Ripley, as she investigates the disappearance of her mother.
Unlike previous game adaptations of the Alien franchise, 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 Alien film rather than the 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.
Alien: Isolation received generally positive reviews and had sold over two million copies by May 2015. Critics praised the game's retro-futuristic art direction, sound design, and the alien's artificial intelligence, but criticised its story, characters, and long runtime. The game won several year-end awards, including Best Audio at the 2015 Game Developers Choice Awards and Audio Achievement at the 2015 British Academy of Film and Television Arts Awards. Several downloadable content packs were also released.
