An unofficial guide to Alien: Isolation, the greatest, scariest horror game ever made. There aren't many computer games that can justify an entire book, but for superfans, Alien: Isolation is truly extraordinary and Perfect Organism reveals all there is to know about every aspect of this masterful game. Discover the rationale and authenticity of the set design and art direction, learn about the alien's unnerving abilities to second-guess the players and the importance of its unique height, find out more about the importance of the dynamic audio and the use of seventies archive soundbites, as well as the darkly beautiful music. And immerse yourself in the technical brilliance of the level design and the user interface, before reading about the deleted content, and the scenes and features that never made the final cut. Alien: Isolation is a game of remarkable depth, complexity, and detail, and together with a level-by-level mission guide, this book will answer all of your questions, as well as many you haven't yet thought to ask!
