Though Ridley Scott’s classic Alien takes place in a distant future, the film’s production values were a product of the late 1970s, with sets and props cobbled together with elements from the era. Rather than evolve the original designs-of-necessity in its upcoming and inspired Alien: Isolation into more modern props and environments, developer The Creative Assembly chose to embrace the “lo-fi sci-fi” concepts found in the horror masterpiece.

“You could say the first part of development was this phase of deconstruction,” Creative Lead Al Hope explains. “Kind of taking everything we knew and loved about the film and pulling it apart, so that when we built new content it would still look and feel as though it were from the film.”

To achieve an in-game design that would mesh with the original film’s aesthetic, The Creative Assembly pored over three terabytes of behind-the-scenes video, photos, handwritten notes on props and continuity photos from the production of Alien, courtesy of the 20th Century Fox archives. The treasure trove even included some rarely seen production pieces, such as detailed blueprints of the cargo vessel Nostromo, which proved vital for creating the spaces within Isolation. Using the source material, the developer made what Hope calls “a brave decision,” and began populating its game with objects and environments created by replicating production techniques used for the film’s development. Computers are slow, clunky and always seem on the verge of breaking down. And it’s all by design.
