Passage: On August 22, 2008, No Known Survivors, a website similar to an alternate reality game that provides an opportunity for visitors to explore the narrative world of Dead Space, was launched. The site depicts two stories, each divided into four chapters, and uses 3D animations, voice acting, original video, Papervision 3D technology, and various other interactive components. The first, Misplaced Affection, tells the story of an organ replacement technician who falls in love with a capable P-Sec officer and slowly loses his sanity as Necromorphs attempt to break down the door to his shelter. The second, Thirteen, follows a sleeper agent who "makes the wrong decision for the right reason", set after Isaac launches the distress beacon. The site is less like a typical alternate reality game and more like a PC adventure game, such as Myst.
