Alone in the Dark is a survival horror video game, and the fifth installment of the series under the same name created by Atari. The game was released for Microsoft Windows, PlayStation 2, Xbox 360 and Wii in Europe, North America, and Australia in June 2008. The PlayStation 3 version, titled Alone in the Dark: Inferno, was released in November 2008 and includes several enhancements from the other versions. The Windows, Xbox 360 and PlayStation 3 versions were released by Electronic Arts in Japan on December 25, 2008.
The Windows, Xbox 360 and PlayStation 3 versions were developed by Eden Games while the PS2 and Wii versions were simultaneously developed by Hydravision Entertainment. The PS2 and Wii version of Alone in the Dark is a completely different game from the PlayStation 3 and Xbox 360 version. Though both have a similar plot, it has largely different levels, removing all the free-roaming from the other versions. Despite receiving mixed reviews, Alone in the Dark was a financial success.
The game begins with an amnesiac Edward Carnby, a paranormal investigator recovering from an exorcism performed on him by a group of occultists led by Crowley. A guard is instructed to take him to the roof for execution, only to be dragged away and slaughtered by an unseen force. He wanders the collapsing building in search of an exit; witnessing several people being killed in a similar fashion as the guard, as well as a young woman becoming possessed by a demon which claims to know of his past. After battling the entity, he meets art dealer Sarah Flores. They make their way to the basement parking garage where they meet Theophile Paddington, the occultist who performed Edward's exorcism and an old apprentice and friend of Carnby's. Theo explains the nature of the Philosopher's Stone and Crowley's desire to unleash its evil power.
Hijacking a car, they drive into New York City, finding it in the same destroyed state as the building; supernatural fissures erupting from the earth. They crash in Central Park and Theo gives Edward the Stone, telling him to find him in a room of a museum before killing himself. On the way to the museum, Edward begins to bleed out from his injuries. Making his way through the destruction, Edward learns his surname from Crowley. Later, his past medical records from an attending medic reveals that he is over a hundred years old, having disappeared in 1938. Finding Room 943 of the Metropolitan Museum of Art, Theo's ghost explains more of the Stone's history. Forged by Lucifer after his fall from Heaven, the Stone tempted men with promises of mass wealth and immortality; in actuality, it merely made them vessels for the Devil's soul.
Sarah stays behind in the museum to research Paddington's notes, emailing Edward various texts as well as receiving some from Crowley, both of which reveal more of his past and the Stone. Delving deep beneath Belvedere Castle, he solves various puzzles trailing the Path of Light. Reaching a hidden chamber in the underground temple, Edward meets Hermes Treismajice, one of the alchemists who built Central Park and the holder of the other half of the Stone - rendering him effectively immortal as he waited for the Carrier of the Stone (Edward) to release him. While driving Hermes back to the museum, Sarah is kidnapped by Crowley and held hostage. In a final confrontation, Edward finally kills the mad occultist by quickly shooting him in the head while he was struggling with Flores. Treismajice then leads them to the innermost chamber.
Inside the chamber, they find a large portal between the living world and the afterlife; a gateway for Lucifer to return to a body. Needing both halves of the Stone to unlock it, Edward and Hermes reunite it on the pedestal only for the Light Bringer to begin repossessing Carnby. Sarah - unwilling to let Edward sacrifice himself - takes the Stone from him, allowing Lucifer to begin possessing her instead. The player is given a choice: to kill her and take the Light Bringer into his own body, or to let her live and allow the Devil to use her as his vessel. If he chooses the former, he becomes fully possessed by Lucifer and declares his intention to rule over humanity. If he chooses the latter, Sarah becomes possessed and the Devil mocks Edward for being so alone; to which he replies, "I'm used to it," before walking away in defeat.
