Excerpt: Amnesia: The Dark Descent (previously known as Lux Tenebras or Unknown) is a survival horror video game by Frictional Games, who previously developed the Penumbra series. Released for Windows, Mac OS X, and Linux platforms, the game features a protagonist named Daniel exploring a dark and foreboding castle, while avoiding monsters and other obstructions as well as solving puzzles. The game was critically well received, earning two awards from the Independent Games Festival and numerous positive reviews. Originally released independently as a download, the game has since been published in retail by 1C Company in Russia and Eastern Europe as well as THQ in North America. A collection of five short stories set in the world of Amnesia, written by Mikael Hedberg and illustrated by the game's concept artists, was also made available. In addition, the game's soundtrack is available for purchase and a free content expansion called "Justine" has been released as well as many fan made expansions and stories.

In addition to a health indicator, Daniel's sanity must be managed. Being in darkness too long, witnessing unsettling events, or staring at monsters will reduce Daniel's sanity, causing visual
